In order to develop a sustainable salmonid aquaculture, it is essential continue reduce the use of protein-rich fishmeal. One promising solution do so plant-derived carbohydrates in diet destined broodstock. However, mammals, reduction protein content (replaced by carbohydrates) parental known have strong adverse effects on offspring phenotypes and metabolism. For first time, effect paternal ma...

This research aimed to evaluate the reproductive potential of hatchery-reared (F1) pike-perch (Sander lucioperca) broodstock fed a commercial diet with low levels long-chain polyunsaturated fatty acids (Lc-PUFA) and wild (F0) forage fish. Reproductive parameters, including pseudogonadosomatic index (PGSI), egg size, latency time, hatching rate, embryo survival, eggs’ acid (FA) composition, as w...

Abstract Oryzias woworae , one of the endemic ricefish species from Sulawesi, is threatened with extinction in their habitat. Domestication aquaculture way to preserve conservation these fish. The success factor for cultivation adaptation immature broodstock a controlled environment gonadal maturation. Adaptation performance after closed system transport first study O. at start an adjustment re...

Betta fish are freshwater ornamental that very popular and have quite high economic value, but the reproductive process still depends on spawning season, so an increase in potential is needed. The experiment was conducted order to determine role of each induction Oocite development (Oodev) hormone diet betta female final maturation morphology gonads. Completely randomized design (CRD) with one ...

In the present study, biological function of recombinant gonadotropin-releasing hormone associate peptide (rGnRH) was tested for induction ovulation and spawning in Sterlet sturgeon (Acipenser ruthenus) broodstock. For this purpose, broodstock were divided into four treatments treated with following preparing procedure: 0.9% NaCl (C); 2.5 ?g kg body weight?1 (BW) LHRH-A2 (luteinizing hormone-re...
