Comparison of growth rate and fatty acid profile of Nereis diversicolor fed with faeces and food of rainbow trout
Rainbow trout farms released always a large amount of organic matter into the environment, resulting in environmental contamination. If these waste can be used as a food source for the production of a secondary organism such as Nereis diversicolor, in addition to increasing production, it will reduce the volume of contamination originating from fish farms. In this regard, determining the nutrit...
متن کاملThe effects of oxygen supplementation on growth and survival of rainbow trout (Oncorhynchus mykiss) in different stocking densities
In this study, the effects of oxygen supplementation in different stocking densities of rainbow trout (Oncorhynchus mykiss) on the specific growth rates (SGR), feed conversion ratios (FCR) and survival rates were investigated in a commercial-scale culture system. High density cultures were maintained in a total of nine (12 m3) flow-through systems supplemented with O2. Initial stocking rates fo...

متن کاملAlternative role of sesame seed replacing fish meal in the diet of rainbow trout (Oncorhynchus mykiss) fingerlings
Rainbow trout is the most important species of cold water fishes in Iran and the feeding diets which improve the quality and growth of this fish are of great importance. Rainbow trout Oncorhynchus mykiss (n=360) specimens with approximate weight of 2±0.02g were fed with different concentrations of sesame seed in their diet instead of fish meal for 120 days. Feeding diets were prepared in 3 sesa...
متن کاملEffect of the selected physico-chemical parameters on growth of rainbow trout (Oncorhynchus mykiss) in raceway system in Iran
A study was conducted to evaluate the correlation between selected physico-chemical parameters of water and their effects on growth of Rainbow trout (Oncorhynchus mykiss) in raceway system in the area of Sarab Gerdu, Iran. The samples were collected from twenty raceways (270- day old fish, surface area 55m2 flow rate 150 ls-1 total production 15 T). Physico-chemical parameters were the fluctuat...
