A 3×4 factorial experiment was conducted for 45 days to determine the effects of diets containing different levels of protein and fat on growth of fingerlings Beluga (Huso huso L.1758). Twelve different diets were formulated with 3 levels of protein (45,50 and 55) and 4 levels of oil including fish oil and sunflower oil (0.5 ,4 , 8 and 12). 1260 Beluga fingerlings with an initial body weight (I...

The aim of this study was to evaluate the influence of stocking density (0.5, 1, 2 and 3 fishL(-1)) and commercial marine fish diets (diet A, B, C and D) over four months on specific growth rate, condition factor, percentage without anomalous pigmentation (partial or total lack of white bands -miss-band) and survival of juvenile Amphiprion percula. Results showed that at 0.5 fishL(-1) densities...
In the present study, the impacts of various concentrations of Aflatoxin B1 (AFB1) on Beluga, Huso huso, under controlled conditions were investigated. Belugas (120±10g) were fed on diets containing 0, 25, 50, 75, and 100 ppb AFB1/kg of diet for 3 months. Results showed various levels of AFB1 do not significantly affect the specific growth ratio (SGR) (P < 0.05) of fish in different treatments...

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...
The aim of this study was to determine the effect of anthocyanin from roselle (Hibiscus sabdariffa) supplemented diets on growth, survival and body composition of rainbow trout (Oncorhynchus mykiss) for 60 days. Fish were fed 0 % (control), 0.5 %, 1 % and 2 % anthocyanin extract in complete random design. Fifteen fish with the same initial weight (14 ± 0. 1 g) were selected and randomly distr...
Substitutability of broccoli by-products (BBP) for Saccharina japonica in feed on growth, carcass chemical composition, and air exposure resistance abalone (Haliotis discus) was investigated. One thousand two hundred sixty abalones were randomly assigned into 18 cages (3 cages/diet; 70 abalone/cage). Two g/kg S. included the control diet (BBP0). The BBP250, BBP500, BBP750, BBP1000 diets prepare...
this study was conducted to determine the effects of mannan oligosaccharide (mos) on growth, some immune responses and gut lactic acid bacteria of common carp. four experimental diets containing 0%, 0.05%, 0.10% and 0.20% mos were prepared. each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 14 g. after eight weeks, survival rate was high i...
