An 8-week feeding trial was conducted to evaluate the effects of dietary commercial prebiotic A-Max, a mixture of mannan oligosaccharides, fructo oligosaccharides and β glucan, on growth and hemato-immunological parameters of great sturgeon (Huso huso) juveniles. After acclimation, fish (initial weight of 28.79±0.85 g) were placed into 12 tanks (30 fish per tank). Basal diet (containing 44%...

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...

This study examined the effects of feeding of two dietary probiotics on growth performance and feed utilization, intestinal colonization and related health criteria, biochemical parameters, hematological indices, and immune parameters and protection against Yersinia ruckeri in Oncorhynchus mykiss during a period of 56 days. The study included 3 groups:1(a control group of fish, 2) a group of fi...

Aim of the study: To evaluate hemato-immunological parameters in Palomino trout compared to naturally pigmented rainbow trout.
 Area Fars province (SW Iran).
 Material and methods: Sixty fish both varieties (30 30 pigmented) were sampled from same pond. After blood sampling, hematological parameters, total serum protein immunoglobulin (Ig), phagocytic activity, respiratory burst lysoz...

Low insecticide exposure has been shown to cause profound effects on non-target organisms, including crabs. Therefore, the changes in hematological parameters, serum biochemistry and antioxidant enzymes Gercacinid crab, Cardiosoma armatum were assessed during 28-day four concentrations of organophosphate chlorpyrifos (0.003, 0.006, 0.03 0.06 mg/l). The results showed a significant (P= 0.0) decr...

ABSTRACT Feed additives, such as β-glucans, nucleotides, ascorbic acid (vitamin C), and α-tocopherol E) can improve fish immunity contribute to enhanced zootechnical performance of the fish. This study aimed evaluate effect different concentrations vitamin- mineral premix with or without inclusion an immunostimulant boost (β-glucans, nucleotides vitamins C on performance, hemato-immunological p...

This research aimed to evaluate the effects of partial or total replacement of fish oil (FO) with unrefined peanut oil (PO) on growth and some physiological parameters of Mozambique tilapia juveniles for 60 days. Three triplicate groups (initial weight 6.36±0.19 g) were fed with isoenergetic and isonitrogenous diets in which FO was replaced with PO in graded increments of 50% (PO0, PO50, PO100)...
