this study was carried out to determine the appropriate size of caspian trout ( salmo caspius kessler, 1877) juveniles for releasing into the rivers that enter south of the caspian sea for stock enhancement, or possibility of cage culture in the caspian sea. a total of 1611 specimens in 4 weight groups of 5, 10, 15 and 20g were exposed to 3 salinity trials which include caspian sea water (11- 1...

As in many parts of the world, aquaculture production in the Mediterranean has been expanding rapidly over recent years (Basurco & Lovatelli, 2005).

The objective of the study was to determine optimal density fingerlings Nile tilapia (Oreochromis niloticus) culture in floating cages with respect growth performance and know effect temperature on during winter period. Tilapia (mean weight 8.5 ± 0.36 g) were stocked at densities 120, 180 360 fish/m3 for 10 weeks. During culture, fish fed a diet contains 35% protein made peanut seed, cottonseed...

Introduction of sahar in cage-cum-pond integration system of mixed-sex Nile tilapia was evaluated using 15 outdoor cemented ponds of 24 m2 (4.9m × 4.9m) size with 1.25 m water depth placing a cage of 1.2m× 1m × 1m size holding 1 m3 water at the center of each pond at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, for 158 days. The experiment was conducted in a completely r...

-"Shrinkage," or unaccounted-for losses of fish during cage rearing, is widely acknowledged among fish culturists who rear salmonid fishes, but the extent of such losses has not been documented . Over 60,000 Chinook salmon (Oncorhynchus tshawytscha) were reared in floating cages at four locations in Puget Sound, Washington, and were hand-counted at the beginning and end of 200+ d of rearing. Av...

The Persian Gulf and its shores are important and strategic areas with a large variety of fish species. Betanodavirus infection is known to be a serious threat to susceptible fish and causing economic damages to the fisheries and fishing industry. Concerning to isolation and confirmation of VNN virus in the Mullet fish (Chelon aurata and C. saliens) in the Caspian Sea and its damages on Mullet ...

Cage culture of Etroplus suratensis (Pearlspot) was carried out in Krishnagiri reservoir, India, a highly productive reservoir to analyze the feasibility growing this species freshwater cages and investigate effect on selected environmental parameters. Fish average weight 5.98 ± 0.52 g were stocked at 10 ind. m3 High-Density Poly-Ethylene floating (3 × 3 2 m) made nylon knotless net with 12 mm ...
