Effect of water current on some growth performance and water quality in a closed rainbow trout (Oncorhynchus mykiss) culture system
The effects of water current increment on rainbow trout ( Oncorhynchus mykiss ) culture were investigated during a 35 day experiment. Fish weighing 5.5 g were stocked in aquarium tanks. Four different water speeds (0, 3.5, 7, 10.5 cm/s) were provided for each treatment in three replicates. These different currents water were provided by reusing outlet water of each culture unit...
متن کاملeffects of water current on some water quality factors in a closed trout culture system
considering the lack of sufficient fresh water resources for aquaculture and at the same time the pollution of fresh water through the process of fish farming, a project was carried out within 15 days to survey the effects of water flow increment on rainbow trout culture by reusing the outlet effluent under a complete random design with 4 treatments and 3 replicate. the water quality factors in...
متن کاملInfectious pancreatic necrosis in a recirculating rainbow trout (Oncorhynchus mykiss) culture system
During October 2009, a suspected outbreak of infectious pancreatic necrosis, with typical signs and high mortality, was observed in cultured rainbow trout (Oncorhynchus mykiss) fry (mean weight of 9 g) in a recirculating system in Fars Province, Iran. Tissue samples, including pyloric caeca as well as pancreatic tissues, liver, kidney, and spleen, were aseptically collected from 20 aff ected mo...
متن کاملEffects of Scrophularia striata water extract on quality and shelf life of rainbow trout (Oncorhynchus mykiss) fillets during superchilled storage
The purpose of this study was to evaluate the effects of Scrophularia striata water extract on the quality and shelf life of the rainbow trout fillet during superchilled storage. Fish samples were treated with 1% and 3% S. striata water extract and then stored at -2°C for 20 days. The samples were analyzed periodically for chemical, microbial and sensory characteristics. Results indicated that ...
متن کاملEffects of stock density on texture-colour quality and chemical composition of rainbow trout (Oncorhynchus mykiss)
This study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size/weight measurement and condition f...
