In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...

The effects of dietary supplementation of garlic (Allium sativum) extract on the growth and disease resistance of African catfish, Clarias gariepinus was evaluated. Also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (MDR) pathogenic bacteria to aqueous extract of garlic was done. Aqueous garlic extract exhibited inhibitory activity against MDR bacteria and the degree o...

To study the growth response of African catfish (Clarias gariepinus) to the diets containing two protein (30 and 35%) and two lipid levels (12 and 18%) in a closed recirculatory system for 60 days, fish were fed to satiation twice daily. The experiment was carried out in triplicate groups. Fortnightly sampling of fish and water samples was carried out. The best result in terms of growth was obt...

Three different species of the genus Macrogyrodactylus Malmberg, 1957, collected from the gills and skin of Clarias gariepinus (Burchell, 1822) from the Middle Letaba Dam and Mokgoma-Matlala Dam in South Africa were examined and identified. This is the first record of a species of the genus in South Africa. The three species are M. congolensis (Prudhoe, 1957)--found on the skin, M. clarii Gusse...

The study was designed to investigate the gross morphometric of heart of farmed African catfish (Clarias gariepinus) in Maiduguri, Nigeria. The total of twenty fish comprises of both male and female were used for this study, the average weight of fish were 980 g, average length of fish were 42 cm, average weight of heart were 1.3 gm and average length of heart were 2.6 cm. Grossly the heart wer...

This study was conducted to assess the effect of the water quality of El-Rahawy drain at El-Rahawy village, Egypt, on the African catfish Clarias gariepinus blood, biochemical parameters and histology of digestive tract, testis and ovaries. In addition to that, samples of water and C. gariepinus fish were collected from the River Nile at Delta Barrage in front of El-Kanater El-Khayria City as r...

Catfish (Clarias gariepinus) is a freshwater fish that widely cultivated in Indonesia. Production cost of farming activities spend 60-70% on the use feed. Therefore, feeding must be effective and efficient so catfish can make good it for its growth. The addition an exogenous enzyme form papain increase efficiency feed utilization. purpose this study was to determine effect growth survival sangk...
