A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s wer...

quality grading and nutrition value determination of fish are. nowadays necessary for aquatic processing. the present study was conducted to investigate a new, applied and cheap method of fillet quality grading for common carp (cyprinus carpio) using fish size, based on mathematical equations. for this reason, 61 specimens of cultured market size carp were used and after filleting, their moistu...

an 8-week feeding experiment was carried out on beluga (huso huso) juvenile to evaluate the effects of different levels of fish oil containing n-3 highly unsaturated fatty acids (n-3 hufas) on fish growth and fatty acid composition. the requirements of beluga juvenile for n-3 hufas were studied by feeding fish diets containing six different levels of n-3 hufas ranging from 1.56 to 17.25% (% of ...

this study was conducted to determine the optimal dietary protein requirement for lemon fin barb hybrid fingerlings. triplicate groups of fish (1.00 ± 0.05 g) were fed twice a day until apparent satiation with five isocaloric (16 kj/g) diets containing varying protein level ranging from 20 to 40% for 60 days. survival was not affected by the dietary protein level. the weight gain and specific g...

In Turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. It is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...
