background: faba bean (vicia faba) is a rich source of protein and carbohydrates that is used as a vegetable ingredient in diet of livestock, poultry and fish, in many countries. objectives: this study was conducted to assess the effects of different levels of faba bean on the serum lipid levels and liver function of farmed beluga sturgeon (huso huso). methods: 144 juvenile beluga (82.38 ± 0.83...

background: probiotics, in form of microbial supplements, are known to be a suitable alternative for antibiotics and can affect the health indicators of host. objectives: the present study was conducted to assess the combined effects of dietary autochthonous saccharomyces cerevisiae and aspergillus niger on haematological and serumbiochemicalparameters of beluga sturgeon (huso huso) juveniles. ...

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...

in this research, acute toxicity (lc) of zinc oxide nanoparticle on beluga (huso huso) andcommon carp (cyprinus carpio) was studied. the experiment was conducted using theorganization for economic co-operation and development (no. 202) method. for bothspecies, 96hlc10 was determined to be more than 200 mg/l. to assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

effect of different photoperiodic regimes was evaluated on growth performance and survival rate of the beluga ( huso huso ) prelarvae and larvae. newly hatched prelarvae were stored in 5 round fiberglass 500‑l tank with different photoperiod (24l:00d, 18l:06d, 12l:12d, 06l:18 d, 00l:24d) till 50 days post hatch with three replicates. light intensity was 200 lux during the experiment. feeding wa...

the study was performed to examine the efficacy of ginger (zingiber officinale) extract on growth performance, biochemical and hemato-immunological parameters in juvenile beluga (huso huso). fish were divided into 4 groups before fed diet for 8 weeks with 0.5%, 1% and 1.5% ginger extract and with unsupplemented commercial diet as the control. results showed that there was a significant differen...
