The present study tried to investigate the effects of probiotic, Pediococcus acidilactici in concentrations of 1× 109, 2× 109 and 3×109cfu kg-1 diet on growth and survival rate of oriental bream fry (Abramis brama orientalis, Berg 1949) in comparison to control diet (devoid of probiotic) for 60 days. In so doing, 180 specimens of oriental bream with initial weight of 2.69&plus...

Because of limitations of production of unicellular green algae (especially in large volumes), this study aimed to culture Artemia using three sources of cheap agricultural by-products that were coupled with small amounts of unicellular algae Dunaliella salina. The results of growth and survival, biomass production, Individual wet weight, wet and ash percent, FCR and SGR and nutritional value o...

to compare the reproductive performance of the wild and cultured stocks of beluga, huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. the semen samples were sampled from 11 wild spawners and 12 cultured brooders. a half of each semen sample was allo...

This study aimed to elucidate the influence of environment pH on survival, growth, energy allocation and oxidative damage of juvenile Scophthalmus maximus (19.89±0.25 g). Six pH treatments (6.3±0.2、6.8±0.2、7.3±0.2、7.8±0.2、8.3±0.2、8.8±0.2) lasting for eight weeks were included. Measurements of survival (SR), feed conversion ratio (FCR), specific growth rate (SGR), weight gain rate (WGR), energy ...

this study was conducted to evaluate the effect of probiotic bactocell, a-max and inflammatory breast prebiotic mixture of these two compounds on growth, feed and larval survival of rainbow trout (oncorhynchus mykiss) conducted for 84 days. testing a randomized complete block design consisting of zero (control), 1.0, and 2.0 grams of probiotic bactocell, 5/1 and 5/2 grams of prebiotic a-max and...
