To determine the effects of spawning frequency and density of incubating eggs on the survival rates of eggs and larvae in rainbow trout, five different groups of broodstocks with varying spawning frequencies were stripped. After fertilization, the percentage of survival at different stages of development, from eying, hatching to free swimming fry stages and also growth rates of larvae were dete...

This study was conducted to investigate the effect of rearing at differing densities and dietary supplementation with vitamin E on growth indices, survival and carcass composition in fingerling rainbow trout in a 6-week trial. Rainbow trout juveniles with initial body weight of 9.6 ± 0. 69 g at two densities of 50 and 100 pieces per 50 liter were fed two diets with the same protein and fat cont...

All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

In the present study effects of different levels of probiotic Pediococcus acidilactici, on growth performance and survival rate of Rutilus kuttum were investigated. Fingerlings Kutum with mean weight of 1±0.235 g were reared for 8 weeks in 500-l fiberglass tanks (15 fish per tank) with 4 diet treatments (with 3 replicates for each treatment). Treatments were included 1× 109 , 2:1×109 , 3× 109 C...

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...

This study aimed at applying both growth and survival approaches to compare three native strains of lactobacilli, belonging to Lactobacillus plantarum, Lactobacillus rhamnosus and Lactobacillus acidophilus species, with two commercial probiotic strains in their tolerance to acid and bile. The association between the data obtained from the methods was studied.  The results of the different metho...
