A study was conducted on Cyprinus carpio spawn (0.002±0.00 g) to determine optimum water temperature and pH. For this purpose, four water pH (5.5, 6.5, 7.5 and 8.5) were selected and each one exposed to three water temperatures (26, 28 and 30°C) for 91 days. The maximum weight gain (3.279±0.84 g), Feed Conversion Efficiency (FCE) (86.49±0.64%) and survival (97±3.85%) were recorded with pH 7.5 at water temperature 26°C. However, growth at 7.5 pH under temperatures 26, 28 and 30°C was statistically insignificant indicating that water temperature does not have much influence on the growth of C. carpio fry and they can adopt temperature variations. © 2013 Inderscience Enterprises Ltd.

A study was undertaken to investigate the cause of mortality in semi-fry of wild collected Asian seabass Lates calcarifer during weaning on Anemia nauplii. The samples tested negative for nervous necrosis virus by PCR. On bacteriological analysis Vibrio alginolyticus was isolated from kidney tissue of infected seabass. The pathogen identity was confirmed by biochemical tests and further confirmed by automated bacterial identification system. The likely transmission of infection might be from rearing tanks or Anemia nauplii used for feeding semi-fry as they are considered to be the prime vectors of these bacteria.

This study was conducted for three years to investigate the aquatic parameters and growth of sea bass at varying stocking densities and sizes and requirement of quantity of forage fish for its culture in ponds. Two separate experiments were conducted: one for determining growth and seed stocking density and the other for ascertaining of quantity of forage fish. Under experiment 1, two trials namely, A and B were conducted with three stocking densities viz. 1000, 1500 and 2000 nos./ha of sea bass in each trial. In trial A, the specific growth rate (3.68%/day) was significantly better (P < 0.05) in T2 (1500 nos./ha stocking density), while in trial B, it was higher (2.06 and 2.00%/day) in T1 (1000 nos./ha) and T2 (1500 nos./ha), respectively, and significantly superior from T3. The survival was 100% in trial B, where advance fingerlings were used, as compared with 34.32% in trial A with fry size. The water parameters like temperature pH, salinity, dissolved oxygen, alkalinity nitrate-N 2 nitrite-N 2 and phosphate were recorded in all the experiments.

The efficacy of red worm (Tubifex tubifex) for converting organic wastes like pig dung, poultry excreta and dairy sludge into worm biomass production was investigated. For this purpose, three experiments each for pig dung, poultry excreta and dairy sludge were conducted in cement trenches for 90 days duration. The poultry excreta produced maximum biomass (126.53 ± 2.16 g), followed by the pig dung (99.47 ± 2.07 g) and dairy sludge (10.09 ± 2.55 g). Waste water discharged from residential area was used for circulation in experimental trenches. Copyright © 2010 Inderscience Enterprises Ltd.

Experiment was carried out on seed production using portable FRP carp hatchery developed by Central Institute of Freshwater Aquaculture, Odisha in the existing water quality and climatic condition prevailing at Udgir town of Latur district, Maharashtra. Matured female brood fishes (5.5 kg) and male brood fishes (6.1 kg) collected from polythene lined brood stock pond were used for breeding operation. Total 8,08,960 eggs were obtained from the females with 72 percent of fertilization and 83 percent of hatching, using well oxygenated and plankton free reservoir water. Total numbers of 483400 hatchlings were produced after 17-19 hours of incubation. As this FRP carp hatchery is easy to install, operate, movable and low cost, this standard technology can be adopted by the farmers of Marathwada region for fish seed production.

The objective of this study was to determine the effect of diets supplemented with soybean meal processed by different heat treatments on growth, survival, and body composition of goldfish (Carassius auratus) fry. The fry (5.25±0.27 cm) were fed isonitrogenous (40%) diets containing soybean meal for 60 days. The first treatment contained soybeans toasted in a pan for 10 min. The second and third treatments contained soybeans oven-heated for 30 and 60 min, respectively. The fourth treatment contained raw soybeans. There were no significant differences (p>0.05) in survival between treatments. There was a significant increase in specific growth rate, protein efficiency ratio, and food conversion ratio with the diet containing soybeans oven-heated for 60 min. No significant differences were detected in body composition among the four treatments.

Larvae of swordtail (Xiphophorus helleri) were exposed to pH levels of 5.5, 6.0, 7.0, 8.0, and 8.5 to study growth and survival under laboratory conditions for 42 days. The larvae were fed formulated dry pellets at 7% of their body weight. The growth and survival rates were highest at pH 8.0 and 8.5, while mortality was complete at pH 5.5. In all treatments, the specific growth rate was higher in the first week and decreased in subsequent weeks. Thus, for swordtail larvae, the pH of the water should be between 8.0 and 8.5.
