Carnitine has been reported to improve growth performance and reduce body lipid content in fish. Thus, we hypothesised that carnitine supplementation can improve growth performance and reduce lipid content in the liver and muscle of yellow catfish (Pelteobagrus fulvidraco), a commonly cultured freshwater fish in inland China, and tested this hypothesis in the present study. Diets containing l-c...

Of Asia, Africa, and the Middle East, there are 15 genera in Bagridae family. The tropical freshwater catfish Hemibagrus hoeveniiis found Asian waters. Bagrids also known as Old World pimelodids, while New bagrids may be more accurate. In Muar, Johor, DNA barcoding has never been utilised to determine species of bagrid catfish. Therefore,this study was done updatethe checklist Baung (bagrid cat...

1. Effects of endosulfan, malathion and carbaryl on circulating T4, T3 and T3/T4 ratio in the freshwater catfish, C. batrachus have been studied during reproductively active phases, i.e. vitellogenic and post-vitellogenic phases of its annual reproductive cycle. 2. Endosulfan provoked a significant increase in T4 and a decrease in T3 as well as the T3/T4 ratio. 3. Malathion decreased T3 and T3/...

The morphological characteristics of the ventricular myocardium and of coronary vascularization were studied in three freshwater teleost species, Piaractus mesopotamicus, Colossoma macropomum and Clarias gariepinus (African catfish), by correlating their ventricular shapes and swimming habits. In Piaractus mesopotamicus and Colossoma macropomum, species with highly active swimming habits, the c...

Flavobacterium columnare is an important pathogen of freshwater fish, implicated in skin and gill disease, often causing high mortality. An outbreak of skin disease in fingerling and adult Nile tilapia, Oreochromis niloticus (L.), cultivated in a recirculation system, was investigated. Four strains were isolated and characterized by biochemical reactions, enzyme production, fatty acid profile a...

Background: The present study compared lethal concentrations (LC50-96 h) of CdCl2, CrCl3, and Pb (NO3)2 between two scaled and scaleless freshwater fish species: Cyprinus carpio (Cyprinidae) and Pangasius hypophthalmus (Pangasiidae). Methods: The experimental fishes were obtained from fish markets/ponds with average lengths and weights of approximately 11.68 ±1.92 and 9.8±1.9 cm, and 25.92±6....

Aquatic animals are important to health-conscious consumers due to their high content of polyunsaturated fatty acids (PUFA) particularly omega-3 FA. This paper reports the fat contents and fatty acid profiles of 20 species of marine fish and 6 species of squid and shrimp (obtained in the fishing port of Pattani, Thailand), in addition to 7 types of Thai freshwater fish to create a fatty acid da...

The purpose of this study is to find out the market opportunities and marketing strategies High Protein Non-Extrusion Floating Feed-in Bogor Regency, West Java Province. Research method with descriptive approach. population in were all freshwater fish farmers Province, samples used farmers, especially catfish Data collection methods: observation, interview, documentation study. analysis statist...

Exposure to the organochlorine pesticide methoxychlor (MXC) is associated with endocrine disruption in several species through biotransformation to mono-desmethyl-MXC (OH-MXC) and bis-desmethyl-MXC (HPTE), which interact with estrogen receptors. The biotransformation of [14C]methoxychlor was examined in channel catfish (Ictalurus punctatus), a freshwater species found in the southern United Sta...

background: the present study compared lethal concentrations (lc50-96 h) of cdcl2, crcl3, and pb (no3)2 between two scaled and scaleless freshwater fish species: cyprinus carpio (cyprinidae) and pangasius hypophthalmus (pangasiidae). methods: the experimental fishes were obtained from fish markets/ponds with average lengths and weights of approximately 11.68 ±1.92 and 9.8±1.9 cm, and 25.92±6.3 ...
