8.1 Wanzhou Eco-Environmental Experimental Station

In 2003, Wanzhou Eco-Environmental Experimental Station continued conducting experimental observation on compound cultivation of grain, economic crops and fruits on ridges in slope field and experimental observation on hedgerow technology in slope land. The station also made investigation on the resources in Wuqiao falling belt of Wanzhou District.

8.1.1 Experiment on compound cultivation of grains, economic crops and fruits on ridges in slope farmlands

In 2003, three modes of cultivation were tested and observed, including compound cultivation of grain, economic crops and fruits on ridges, compound cultivation of grain, economic crops and fruits on flat lands, and compound cultivation of grain and economic crops on flat lands. The results showed that compared with compound cultivation of grain, economic crops and fruits on flat lands and compound cultivation of grain and economic crops on flat lands, compound cultivation of grain, economic crops and fruits on ridges could increase water content of soils and different layers of soils with less lapse rate of soil moisture content after rainy days and obvious water conservation and increasing efficiency. With the mode of compound cultivation of grain, economic crops and fruits on ridges, content of various kinds of nourishment in the soils was obviously higher than the other two modes and increased compared with 2002, and the growth rates of organic substances, total nitrogen, total phosphorus, total kalium, available nitrogen, available phosphorus and available kalium were 25.6%, 24.8%, 3.4%, 1.8%, 14.9%, 11.4% and 13.2% respectively with outstanding efficiency of soil fertilization, effectively reducing soil erosion and surface runoff, showing contribution of vegetable cover to conservation of soil and water.

Results of comparison between furrow soil and ridge soil in the mode of compound cultivation of grain, economic crops and fruits on ridges showed that various kinds of nourishment of furrow soil had reached or exceeded the level of ridge soil. Nourishment of furrow soil and ridge soil was both higher than 2002 with growth rate of the former higher than the latter. Among ridge soil and furrow soil, grains smaller than 0.02mm accounted for 65.8% and 46.2% respectively.

8.1.2 Experiment on hedgerow mode in slope fields

In 2003, comparison tests and observation on hedgerow mode in slope fields were made through establishing mode sub-areas respectively in 2 standard runoff observation fields at the slope of 25¡ã, sub-area in mode of shaddock-king grass hedgerow agricultural technology and sub-area in mode of all-crop flat cultivation along the slope.

The results of comparison showed that the mode of shaddock-king grass hedgerow mode could make the soil containing more water than the mode of all-crop flat cultivation along the slope. After 2 years' cultivation, water conserving and storing capacity of the soil was enhanced and soil moisture content obviously increased with gentle diminishing at a lower lapse rate, and larger changing rates of water content of different soil layers; the soil physical-chemical property was obviously improved; soil fertility was obviously heightened and higher than 2002; the growth rates of organic substances, total nitrogen, total phosphorus, total kalium, available nitrogen, available phosphorus and available kalium were 8.8%, 7.1%, 0.6%, 0.2%, 0.3%, 3.1% and 6.7% respectively. Nourishment was higher on the bottom of the hedgerows than between them, but the whole nourishment was higher than that in 2002 with the growth rate on the bottom of the hedgerows higher than between them. Nourishment content of soil under all-crop flat cultivation mode dropped a little because of serious soil and water losses.

8.1.3 Investigation on the resources in Wuqiao falling belt of Wanzhou District

According to the operation plan of the Three Gorges reservoir water level from 145m to 175m, Wuqiao falling belt in Wanzhou District covers a total area of 1,250.55 hectares. Based on the different types of land-use, the area of cultivation is 707.60 hectares; the area of township and rural residential spots and that occupied by industrial enterprises and mines is 206.64 hectares, the area of landscape is 129.57 hectares, water area is 86.71 hectares, forest area is 69.82 hectares, unused area is 46.20 hectares, traffic used area is 2.06 hectares and the area of grazing grass is just 1.97 hectares, accounting for 56.5%, 16.5%, 10.4%, 6.9%, 5.6%, 3.7%, 0.2% and 0.2% respectively.

8.2 Zigui Eco-Environmental Experimental Station

In 2003, Zigui Eco-Environmental Experimental Station continued the monitoring and research on soil erosion in the front of the Three Gorges reservoir area and pilot tests of ecological agriculture in mountain areas of low hills (altitude < 600m), semi-high hills (altitude from 600m to 900m) and high hills (altitude ¡Ý900m).

8.2.1 Monitoring of water and soil losses

Results of continuous monitoring on the typical runoff fields in the whole year of 2003 showed that: all the grass coverage, straw coverage and hedgerow technologies had function of water and soil conservation; contour-buried membrane leaking-proof wall had certain capacity of water conservation, but would cause serious soil erosion on bare land. Under shift cultivation mode between bare-land navel orange garden and grass (perennial ryegrass) - grass (Amaranthus hypochondriacus), rainy season caused bare land and artificial cultivation measures could cause  a large amount of water and soil losses. Year round cultivation of Alfafa and flower-generated oil plants accompanied with contour-buried hedgerow technology and mode of navel orange garden interplanted with trifolium repens covered with the straws could bring about better ecological benefits, increasing fertility of the land and protecting water and soil.

Ecological adaptation analysis on the regional navel orange industry showed that it was very important for increasing output of navel orange to change local climate through artificial measures.

8.2.2 Experiment demonstration of upland ecological agriculture

In 2003, this experiment station conducted 5 experiment projects on upland ecological agricultural technologies. They were: high, middle and low altitude stereo-agricultural mode demonstration; high and low altitude soil fertilization technology experiment; high altitude soil maturation technology experiment, Houttuynia cordata Thuhb potash fertilizer test and a complete system of pollution-free navel orange cultivation technologies. The results showed that it would have outstanding economic benefit to develop ecological agriculture in line with local conditions of land at different altitudes in the reservoir area. Compared with current mode of agricultural cultivation, all the following modes could raise economic efficiency, increase output of the land and bring about more economic benefits: cultivating corn, potato and vegetable in high mountain land, cultivating rice and vegetable in middle mountain land and cultivating navel orange interplanted with vegetable and mellow. Using farmyard manure in cultivation of corn, broad bean and wheat was beneficial to land fertilization and maturation, increasing output and enhancing capability of the land in high mountain area; Interplanting navel orange garden with trifolium repens could obviously increase unit productivity of the navel orange and improve the quality. For the upland soil short of phosphorus and potash, using more potash and organic fertilizers could obviously upgrade the output and quality of Houttuynia cordata Thuhb.

8.3 Xiaogang Eco-Environmental Monitoring Station

In 2003, Xiaogang Eco-Environmental Monitoring Station conducted continuous observation on ground water dynamics and soil gleization indicators under different levels along the route between Xiaogang and Shi Dock, and the water balance regarding precipitation and evaporation within Xiaogang Station. The station also gave emphasis to the analysis on the influence of water storage of the reservoir to the water level of the Yangtze River and underground water level in the light of water storage, power generation and navigation opening in the second stage of the Three Gorges project.

8.3.1 Monitoring of groundwater dynamics

Neighboring the Yangtze River to the south and the Jing River, a branch of Han River, to the east, the area of Hong Lake is located in the downward area of the four lakes area in Jiang-Han plain with low and flat terrain. The altitude ranges between 22.0m and 25.0m, with relative altitude difference less than 2.0m and slope less than 5%. The surface water within this area is discharged into the Yangtze River through the Xintan estuary gate on the mainly west-to-east main trunk of the four lakes. In addition to the water generated locally, this area also receives water from mid and up stream areas of the four lakes. With water flow impeded, the water level of the groundwater in this area is rather high. The ground water includes mainly the pore water in the Fourth type of unconsolidated rock (phreatic water and pressure water) and deep crack water.

In 2003, the annual average of groundwater level in all observation wells ranged between 21.45m and 22.57m. The annual variation degree of the groundwater level ranged between 0.76m and 2.07m.

The analysis on correlation between pressure water/phreatic water and the water level dynamics of the Yangtze River indicated that the pressure water and phrealic water had very obvious correlation with the water level of the Yangtze River. In the period of storing water in the Three Gorges reservoir, the water level dynamics of the Yangtze River observed from the side of Honghu Lake showed that the water level of the Yangtze River was gradually dropping after the water storage started, from 27.87m, the peak value before storage, to the valley of 23.95m, and returned gradually by the end of the month. The monthly average water level was 25.72m, 1.96m lower than that in June 2002. During water storage, the level of pressure water also dropped a little with monthly average water level obviously lower than 2002.

8.3.2 Monitoring of soil gleization indicators

In 2003, the monitoring of soil gleization indicators was continued for groundwater sections with different gleization levels from Xiaogang Farm to Shi Dock. The indicators were the same as 2002. The results showed that the gleization indicators were obviously different in winter and summer. The three indicators, the contents of total reducing materials, activated reducing materials and Fe2+, had larger degree of change in winter than in summer. No matter degleization or reducing gleization, changes were violent in surface layer while slowly in core soil layer. So the core soil layer became the soil section layer reflecting the status and degree of soil gleization.

Compared with 2002, the measured value of gleization in 2003 (such as the total amount of reducing materials) was obviously less, especially in winter.

8.4 Terrestrial Plant Monitoring and Experimental Station

In 2003, main works of the terrestrial plant monitoring and experimental station included meteorological element monitoring, sampling belt setting up for biodiversity monitoring, ecological research on Adiantum reniforme var. Sinense and Myricaria laxiflora, and the conservation of rare and endangered plants using ex-situ approach.

8.4.1 Meteorological monitoring

In 2003, the annual mean temperature in Longmen River area was 10.4¡æ, while the extremely highest was 32.8¡æ and the extremely howest was -12.1¡æ. The frost-free period was 186 days. The average temperature was 20.7¡æ in July and 0.0¡æ in January. For most months, the monthly mean temperature varied little compared with those in seven year from 1997 to 2003, but the mean temperature in May (13.9¡æ)was obviously lower than the average value (15.2¡æ) in the same period of the 7 years, and the mean temperature in August (20.6¡æ) was obvious higher than the average value (19.6¡æ) in the same period of the 7 years. The annual precipitation was 1,476.9mm, 79.8mm higher than the mean value for 7 years. Thehighest precipitation occurred in July, reaching up to 348.5mm. There was little difference in monthly precipitation compared with the average in 7 years while the monthly precipitation in April, May, July and September increased significantly compared with the average for 7 years by 47.0mm, 52.7mm, 83.8mm and 44.3mm respectively.

8.4.2 Biodiversity monitoring

In October 2003, the station completed the setting-up and investigation of the fixed sampling belt for monitoring in Yunyang. This sampling belt was located at Nanxi Town of Chongqing Municipality's Yunyang County (on the north bank of the Yangtze River and geographically located at 31o04'N and 108o51'E, with altitude ranging from 290m to 1,040m). Serious influence of human activities for a long period had completely destroyed the primeval vegetation. The land at low altitude was mainly cultivated with fruit trees. The natural vegetation was composed only of the deteriorated shkub-grassland scatter in some parts. In the area at altitude over 700m there were some Pinus massoniana and Cunninghamia lanceolata, which were the main forest resources in this area mainly composed of aerial seeded and man-planted forests added with some secondary natural forests.

Yunyang fixed sampling belt for monitoring is composed of 9 fixed monitoring quadrats varying with altitude gradient varied continuously. The species in the sampling belt was rather less. More than 54 species of higher plants in total were found in the investigation. The species were mainly from families of Gramineae, Rosaceae, Cyperaceae and Compositae etc. The whole monitoring sampling belt was composed of 6 vegetational froms including Pinus massoniana forests, Cotinus coggygria scrub, Cupressus funnebris young forests, Coriaria sinica scrab, Heteropogon contortus herbosa and Imperata cylindrical var. major herbosa.

8.4.3 Ex-situ conservation of rare and endangered plants

By the end of 2003, a total of 35 rare and endangered plant species in the reservoir area had been conserved using ex-situ approach, accounting for 75% of the rare and endangered plants (47 species or varieties in total) in the reservoir area, already exceeding the target preset. Most of them were in good condition and at least 15 stems of more than 50% of the species were reserved. The number of reserved stems of some species that need particular conservation such as Myricaria laxiflora exceeded 500 and the reserved stems of Adiantum reniforme var. sinense exceeded 250, meeting the need for long term reservation.

In the process of ex-situ conservation of rare and endangered plants in 2003, more efforts were given to the protection of those plants already under conservation and long term monitoring of their growth. Through breeding, number of some rare and endangered plants increased, such as Myricaria laxiflora and Adiantum reniforme var. Sinense etc. At the same time, an important evergreen broad-leaf forestation species - Castanopsis fargesii was introduced into the reservoir area.

8.5 Estuary Eco-Environmental Monitoring Station

In 2003, the station continued its monitoring and research on the water salinity dynamics in the border section between land and sea as well as the water eco-environmental monitoring in estuary area.

8.5.1 Water salinity dynamics

Three monitoring sections in Yinyang Town, Daxing Town and Xinglongsha High-quality Seed Farm were set up at the border of land and sea, about 4, 22 and 35 km away from the river mouths. Three monitoring points were established for each section, about 200, 500 and 1,000m away from the Dam of the Yangtze River, mainly for monitoring water quality of the main stream of Yangtze north tributary, water quality inside the water gates near the sections, soil electronic conductivity, negative pressure of the soil, groundwater level and the groundwater electronic conductivity.

The monitoring results showed that soil moisture dynamics and soil salinity dynamics were two factors of the soil water salinity dynamics, among which the groundwater dynamics was the most dynamic and most direct factor affecting soil water salinity dynamics. The monitoring section in Yinyang Town was located at littoral plain, so the burial depth of groundwater was rather less but the salt content of soil was rather high. Precipitation, evaporation and burial depth of groundwater were the most important factors affecting soil water content. In recent years, the burial depth of groundwater showed a tendency of gradual reduction, because the negative pressure of soil was in consistence with the changing pattern of the burial depth of ground water. The soil negative pressure has the lowest value in winter and spring when the water content of soil is the highest. The biggest soil negative pressure occurs in summer and autumn when the soil water content is the lowest. Particularly, the maximum soil negative pressure was measured in August and September. Precipitation and evaporation as well as their relative value decide the speed and direction of moisture movement. In certain degree, the level of groundwater mineralization decides the salt content of soil. Precipitation, evaporation and groundwater mineralization became the most important factors affecting the salt content of soil. In view of the changing pattern of salt content of soil between different years, the salt content of soil showed a overall tendency of decreasing, a status of natural eluviation of salt. There is a close hydraulic relationship between in-land river water and groundwater, with in-land river water supplementing or draining groundwater. So, the electronic conductivity between them is very close.

The change of soil negative pressure in Daxing Section was in consistence with time like the change of groundwater burial depth, mainly along with the change of seasons. The dynamic change of soil salt content was relatively steady. The degree of dynamics was relatively less. The effect of precipitation, evaporation and change of groundwater burial depth was no so obvious as in Yinyang Section, but the overall changing tendency was still rather obvious. It appeared that the change of soil salt content lagged behind the change of groundwater mineralization in certain degree. Electronic conductivity of the Yangtze River water changed along with the change of seasons in rather a large degree, while the electronic conductivity of the groundwater change along with the change of seasons in a lower degree and slowly, reflecting that the effect of the Yangtze River water to the groundwater was lagging behind.

8.5.2 Non-biological environment

¡ñ Hydrological factors
Within the marine area investigated, the water temperature ranged from 18.25¡C to 22.03¡C, with an average of 20.70¡C. By the large, the distribution pattern of water temperature was as follows: The temperature of water was higher inside the Yangtze River estuary and near the coast and higher off the coast. The salinity within the Yangtze River mouth was 3.00-5.47, while the salinity outside the river mouth ranged between 10.82 and 34.32, with an average of 28.83. The seawater near the coast was muddy with low transparency (mainly because of the effect of the muddy river water), while the seawater off the coast was clear with higher transparency.

¡ñ Water Chemical factors
The average monitored values of 6 indicators including dissolved oxygen, pH, phosphate, nitrate, ammonia nitrogen and total nitrogen were lower than those of 2002, but the averages of the other 3 indicators including COD, silicate, nitrite and total phosphorus were higher than those of 2002.

¡ñ Sedimentation factors
The Yangtze River carried a large amount of muddy and sand out of the estuary to the sea. Content of the soliquoid took obvious declivity. In 2003, the annual highest content of soliquid was not found inside the estuary but outside the estuary near the mouth and the northwest of the monitoring area out of the estuary, far lower than the usual monitored level. In the whole monitoring area, the content of soliquid ranged between 0.7 and 747.5 mg/L with an average of 51.0 mg/L. The distribution of ignition loss of soliquoid was quite consistent with that of the soliquid, lower near the estuary and higher in the pelagic sea, lower on surface and higher on bottom layer. The ignition loss of soliquoid ranged between 0.1 and 41.5 mg/L, with an average of 4.6 mg/L, also lower than 2002 obviously.

8.5.3 Biological environment

¡ñ Chlorophyll a and primary productivity
In 2003, the content of chlorophyll a and primary productivity were all significantly higher than 2002. The content of surface chlorophyll a ranged between 0.471-13.956 mg/m3, with an average of 2.010 mg/m³, changing by a big margin. The primary productivity in the ocean area was 35.361 and 999.389 mgC/m^2¡¤d, with an average of 259.001 mgC/m^2¡¤d. Affected by the runoff of the Yangtze River, in water area in the west of 122¡ã15¡äE, the content of soliquid was much higher and the water quality was muddy with transparency lower than 1.0m, and less than 0.5m at the mouth and inside the river course. The primary productivity of these water areas was rather lower.

¡ñPhytoplankton
A total of 95 species of phytoplankton were collected and examined during the monitoring and investigation, including 75 species of diatom and 17 species of inoflagellate, 1 species of blue algae, one species of green algae and one species of gold algae. Among offshore law salt species, Skeletonema costatum was dominant in quantity. The number of phytoplankton in the investigation area was 1.0¡Á104 - 54665.68¡Á104/m³, without significant change, with an average of 3037.11 ¡Á104/m³. In the middle of the investigation area, Skeletonema costatum formed a large concentration area. The domination of Skeletonema costatum was over 99%. Moreover, a small sized concentration area was also formed by the Skeletonema costatum at the mouth of the estuary.

¡ñ Zooplankton
A total of 88 species (classes) of zooplankton (including some bottom dwelling organism and their synchoropaedia) were monitored, investigated, collected and identified, including 30 species of copepod, 12 species of Tubularla crocea, 8 species of synchoropaedia, 6 species of shrimp and 1 species of Cumacea. According to analysis of historical data, the density of zooplankton in the investigation area showed a tendency of decrease from year to year. But in this investigation, the density of individual zooplankton saw a little increase. The overall average density of zooplankton was 150/m³. The largest density of zooplankton was  982/m³ . The distributions of different populations were different in geographical location and density, with different populations of zooplankton dominating different geographical locations.

¡ñ Benthos
In the sampling investigation and analysis appraisal, there were a total of 132 species of benthos, including 34 species of mollusk, accounting for 25.8%; 17 species of carapace, accounting for 12.9%; 66 species of polychaete, accounting for 50.0%; 5 species of echinoderm, accounting for 3.8% and 10 species of others, accounting for 7.6%. In composition of species, polychaeta had the highest percentage, belonging to dominant one. The average of total biomass in the sample was 23.13 g/m². Among them, the average biomass of mollusk was the highest, reaching up to 9.73 g/m², and then the average biomass of the others inorder were 7.88 g/m² for polychaeta, 3.42 g/m² for carapace and 1.8 g/m² for echinoderm. On the other hand, there appeared a large amount of pollution tolerance species, causing increase of the total density of benthos, which means that part of the water near estuary of the Yangtze River was polluted in certain degree.

¡ñ Fishery plankton
In the investigation, 109 spawns and fry fishes were caught in total, including 24, all of which were floating spawns, belonging to 3 families and 4 species. The fry fish totaled 85 tails, belonging to 8 families and 9 species, except 1 fresh water species. In vertical trawl sampling, 24 spawns and 4 tails of fry fish were caught in total. Among spawns, the number of species of Sciaenidae was the largest. In horizontal trawl net sampling, no spawns were caught but 81 tails of fry fish in total, most of which were Engraulidae.

8.5.4 Fishery resources

In the investigation of fishery resources, a total of 61 species of biological resources were obtained, including 39,552 tails, weighing 3,544,262g, with average weight of each individual at 89.6g. Among these, there were 34 species of fish, 15 species of shrimp, 6 species of crab, 3 species of antispdix, 1 species of jellyfish, 1 species of cowfish and 1 species of pomfret. Number of fish species investigated this year was less than before. Except invertebrate whose species were a little more than 2002, the number of fish species was just 53% of that of 1998.

Compared with the autumn of 2002, the dominance of cutlass fish decreased and dominance of Cyanea capillata Linnaeus increased sharply, which distribution had expanded to the whole areas from a few stations in the north.

8.6 Peculiar Fish Experimental Station

In 2003, the major targets of peculiar fish experiment were Procypris rabaudi and Sinilabeo rendahli. The repeated experiments on artificial propagation of Ancherythroculter nigrocauds and Megalobrama Pellegrini in the same time, and information sere further collected on biology and artificial propagation of other peculiar fish. 20 times of habitat investigation were conducted in the whole year. The scope included mainstreams of the Yangtze River, the Laixi River, the Longxi River, the Chishui River, the Tang River, the Jialing River and the Mudong River etc. Through the investigation, information about distribution and catch amount of peculiar fish was obtained and data about Ancherythroculter nigrocauda and Magalobrama pellegrini were supplemented.

8.6.1 Biological characters of Procypris rabaudi

In 2003, the station collected data about Megalobrama pellegrini, Rhinogobio cylindricus, Rhinogobio ventralis Sauvage and Procypris rabaudi etc. were collected, and special research was conducted on biological characters of the Procypris rabaudi. Procypris rabaudi belongs to Cyprinidae family and Procypris genus, a fish species with a larger body and high economic value specially distributing in the upstream of the Yangtze River. As the results of investigation showed, the major distribution spots of Procypris rabaudi included Luzhou section, Hejiang section, Mudong section of the Yangtze River, down stream of the Chishui River, down stream of the Jialing River and first level branch of the Yangtze River near Hejiang. The results of investigation showed that the Procypris rabaudi was composed of 9 age groups, from 0 to 8 years old. Compared with the data of 1970's, the mature ones with larger bodies (over 4 years old) decreased obviously. Procypris rabaudi become sexually mature at 2 years old, but some of their sexual glands would not be mature even by 5 years old. The propagation season is from March to May each year. Among the propagation group, Procypris rabaudi at the age of 2 or 3 account for 60% and the ratio between the male and female is 1:1.08. Procypris rabaudi is a kind of typical omnivore fish. The major foods include fresh water conchocelia, Gastropoda, aquatic insect, aquatic growth and algae etc. The habitats of Procypris rabaudi include river section with rocky geology, rock fissures and deep pond etc. The fry fish often appear in groups in meanders of large rivers, down stream of river branches and estuary etc. in spring and autumn seasons.

8.6.2 Experiment on artificial propagation

In 2003, the Peculiar Fish Experimental Station made dozens of times of experiments on artificial propagation, all adopting medical inducing method.

In the 4 times of artificial propagation experiments on Ancherythroculter nigrocauda, inducing rate reached 100%, average fecundation rate reached 89.5% and average birth rate reached 70.4%. In the 7 times of artificial propagation experiments on Megalobrama pellegrini, average inducing rate reached 91.1%, average fecundation rate reached 84.0% and average birth rate reached 67.7%. The data about early growing of Megalobrama pellegrini was supplemented. In the 4 times of artificial propagation experiments, primary success was achieved one time. No success was made in the 4 times of artificial propagation experiments on Sinilabeo rendahli. In addition to above, artificial propagation experiments were also conducted on major economic fishes in upper reaches of the Yangtze River such as Leiocassis crassilabris, Mystus macropterus,Spinibarbus sinensis, Coreius heterodon and Pelteobagrus vachellii etc. These experiments were significant for protection of the fishery resources in the upper reaches of the Yangtze River. The 5 times of artificial propagation experiment on Spinibarbus sinensis improved its birth pattern, among which 3 times of success were made on reducing, with reducing rate ranging from 42.9% to 75.0%, fecundation rate from 47.7% to 83.3% and birth rate from 50.0% to 72.0%.

8.6.3 Experiment on artificial raising and training

In 2003, artificial raising and training experiments were continued on Ancherythroculter nigrocauda, Megalobrama pellegrini, Procypris rabaudi, Sinilabeo rendahli, Coreius guichenoti, Rhinogobio ventralis Sauvage, Rhinogobio cylindricus, increasing parent fish reservation of Ancherythroculter nigrocauda, Megalobrama pellegrini, Procypris rabaudi and Sinilabeo rendahli. The results of experiment showed that for artificial raising and training, the Procypris rabaudi should be injected with narcosis at the first time when it was caught, otherwise the survival rate in raising and training could not be high, no matter the wild fish was injured or not. It was rather easier to raise and train Sinilabeo rendahli.
