The aim of this study was to investigate the effect of different dietary protein levels on growth, survival and body composition of Hediste diversicolor. Three isocaloric diets with three different protein levels containing high protein (50%), medium protein (35%) and low protein (20%) were designed in three replicates in completely randomized design. Hediste worm larvae weighing 0.02±0.005g we...

having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...

in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...

This study aimed to determine the effects of replacement fish meal by different levels of gammarus meal on growth performance and body composition of juvenile Siberian sturgeon (Acipenser baerii). We distributed 245 Siberian sturgeon juveniles (initial body weight: 14.24±0.15 g) in five treatments and three replications. The experimental diets were replaced by 10%, 20%, 30%, and 40% gammarus me...
