Changes in serum biochemical parameters and digestive enzyme activity of juvenile sobaity sea bream (Sparidentex hasta) in response to partial replacement of dietary fish meal with poultry by-product meal.

A 60-day experiment was conducted to evaluate the effect of dietary fish meal (FM) replacement with poultry by-product meal (PBM) on digestive enzymes, non-specific serum enzyme activity, and serum biochemical parameters of juvenile sobaity sea bream, Sparidentex hasta, weighing 29.27 ± 0.06 g.

Comparison of proteomic profiles in the ovary of Sterlet sturgeon (Acipenser ruthenus) during vitellogenic stages.

One of the challenges of sturgeon aquaculture is that sturgeon takes an extended amount of time to reach sexual maturity. The pattern of the protein expression in relation to the late maturity of sturgeon can help to better understand changes in sexual maturity. 17β-estradiol (E2), testosterone (T) and vitellogenin (Vtg) levels were examined at all stages of sexual maturation in Sterlet sturgeon (Acipenser ruthenus).

Combined effects of dietary low molecular weight sodium alginate and Pediococcus acidilactici MA18/5M on growth performance, haematological and innate immune responses of Asian sea bass (Lates calcalifer) juveniles.

Six weeks feeding trial was conducted to examine the effects of dietary administration of low molecular weight sodium alginate (LMWSA) and Pediococcus acidilactici MA 18/5M (PA) on humoral and mucosal immune responses, haematological parameters and growth performance, of Lates calcarifer juveniles. Fish (12.0 ± 0.

Growth Performance, Hemato-Immunological Responses, and Digestive Enzyme Activities in Silvery-Black Porgy (Sparidentex hasta) Fed Dietary Bovine Lactoferrin.

An 8-week study was conducted to evaluate three different diets supplemented with bovine lactoferrin (LF) at 0 (control), 800, and 1200 mg LF kg diet on somatic growth, hemato-immunological parameters, antioxidant status, and digestive enzyme activities in silvery-black porgy (Sparidentex hasta) juveniles. Fish fed the 800 mg LF kg diet had higher growth performance and feed utilization parameters than the other groups. Hematological and liver antioxidant parameters were not affected by dietary LF supplementation.
