Levels of dietary carbohydrates and lipids have important effects on the growth, health, glycolipid metabolizing capacity hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂). This experiment evaluated effect carbohydrate to lipid ratios (CHO:L ratio) serum biochemical indices, intestinal morphology activity digestive enzymes, ability metabolize in grouper. Six iso-nitrogenous (500 g...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

this study was conducted to determine the effects of mannan oligosaccharide (mos) on growth, some immune responses and gut lactic acid bacteria of common carp. four experimental diets containing 0%, 0.05%, 0.10% and 0.20% mos were prepared. each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 14 g. after eight weeks, survival rate was high i...

The study aimed to determine the optimum dietary lysine level of orange-spotted rabbitfish Siganus guttatus Bloch, 1787 (average body weight range 5.2 7.6 gxfish-1). feeding trial was conducted for 8 weeks employing six experimental diets which were isonitrogenous, isocaloric, and isolipidic (35% crude protein (CP), 18.3 MJxkg-1 gross energy, 5% lipid). content ranged from 1.22 g 2.12 xkg-1 dry...

Abstract We have evaluated the effects of different fish feeds on body composition, growth, and enzyme activities Labeo rohita (Rohu). In total, 240 fishes between average weights 24.77±2.15g were studied. The treatments applied in a completely randomized design, with 4 60 each. Treatments consisted four [Oryza (T1), AMG (T2), Aqua (T3), Supreme (T4)]. Body growth performance, evaluated. There ...

Mahseer aquaculture activities are still relatively low because they constrained by slow growth. Potassium diformate can promote growth improving digestion. This research aimed to determine the optimum dose of potassium addition artificial feed for best rate in mahseer fingerlings. The was conducted from July – August 2022, hatchery Faculty Fisheries and Marine Sciences, Padjadjaran University,...

To provide a scientific basis for artificial culture, the effects of different breeding densities, feeding cycles, and light environments on the growth regulation of Poecilobdella manillensis were studied. After P. manillensis were cultured at breeding densities of 250 ~ 3250 leeches m-2; feeding cycles of 2 ~ 16 days; and a light environment with noise or a light-free environment without noise...
