We have investigated the effect of melatonin (MLT) on specific growth rate (SGR% day(-1)), condition factor (k), gonado-somatic-index (GSI), histological structures of gonads, serum as well as gonadal protein and lipid in Nile tilapia Oreochromis niloticus. MLT treatment in the dose of 25 μg/L for three weeks reduced SGR% day(-1) (0.9±0.04) as compared to control (1.23±0.026). The GSI value was...

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...

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...

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,...

Two on-farm juvenile performance trials were conducted at a hatchery in Bangladesh to compare genetically improved strain of farmed Nile tilapia (GIFT) and local (LS) produced by commercial operators. A 21-day early nursing trial was five replicate hapas followed 27-day advanced six hapas. The mean feed conversion ratios (FCR), specific growth rates (SGR), individual final weights, production y...

This study investigated the effects of sudden weaning of angel fish larvae (Pteraphylum scalari) from Artemia nauplii to commercial larval feed. Four days post hatch (DPH) larvae were reared in four different weaning protocols (TR1-TR4) with triplicates in a complete randomize design. Larvae in TR1 and TR4 were exclusively fed Artemia nauplii and dry feed respectively. In TR2 and TR3, larvae we...

Escherichia coli O157:H7 can contaminate raw ground beef and cause serious human foodborne illness. Previous reports describe the behavior of E. coli O157:H7 in ground beef under different storage conditions; however, models are lacking for the pathogen’s behavior in raw ground beef stored over a broad range of temperature. Using sterile irradiated raw ground beef, the behavioral kinetics of 10...

Federal healthcare spending has been a subject of intense concern as the US Congress continues to search for ways to reduce the budget deficit. The Congressional Budget Office (CBO) estimated that, even though it is growing more slowly than previously projected, federal spending on Medicare, Medicaid and the State Children's Health Insurance Program (SCHIP) will reach nearly $900 billion in 201...
