persian sturgeon (acipenser persicus) is a valuable fish caught in the caspian sea. in this study, effect of frying, the most common cooking methods on nutritional properties of the persian sturgeon fillet were investigated. the raw and fried samples were analyzed for amino acid composition, protein and fat content, in vitro digestibility and nutritional parameters. the results showed that the ...
effects of short terms starvation periods on body composition of siberian sturgeon (acipenser baeri)
fish may experience periods of food deprivation or starvation in nature (such as seasonal migration and reproduction) and under culture conditions (unpredictable stress such as transporting and sorting). with respect to vital role of starvation periods on body composition, the current study was carried out in autumn 2010 at international sturgeon research institute. after adaptation for one mon...
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...

introduction: at least 60% of the estimated 300,000 metric tons of tuna that are processed in iran areby-products which arebeingwasted and converted to non-human products as fish meal or fertilizers. therefore, a major challenge facing the tuna canning industry is to find the new processes to utilize tuna processing by-products (mainly dark muscle) into valuable foods. the characteristics of tu...
The aim of this study was to investigate the effect of fermented silage on growth performance and apparent digestibility of protein at feed of rainbow trout. In this study, Anchoy Kilka meal were mixed with 25% wheat flour and inoculated with microorganisms (108 cell/ml) and kept in an incubator for 14 days at 37 ºC. Fermentation of Anchoy Kilka has resulted in a significant increase in moistur...
In this research, controlled changes of rainbow trout muscular composition cultured in brackish water (14.1ppt) and freshwater (4.3ppt) was compared. Some 180 juvenile rainbow trout with a weight of 47.2±0.1g each were released in 6 polyethylene tanks with a capacity of 1.5m³. During the experiment, water temperature was kept constant. Feeding fish was conducted using common Faradaneh food and ...
A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...
The study was conducted with a completely randomized design consisting of four treatments in triplicates. Experimental diets were formulated to contain four different lipid levels (8, 10, 12 and 14%) at constant protein level (46.8%) and different gross energy of 4314, 4417, 4519 and 4622kcal/kg, respectively. Kutum fry (average weight, 203±4mg) were randomly assigned and distributed at a densi...
