Induction of triploidy is one of the biotechnological methods in aquaculture used for genetic manipulation. It refers to a state where organisms have three complete sets of chromosomes instead of two and can result in sterility. Caffeine treatment that is safe and inexpensive, serve to induce triploidy in catfish. To suppress the second meiotic division, fertilized eggs were exposed to three di...
Moringa oleifera commonly referred to as the drumstick tree is a plant from the Moringaceae family. It is a medicinal plant that was found to be loaded with different bioactive chemicals or secondary metabolites such as vitamins, minerals, saponins, alkaloids, flavonoids, carotenoids etc. which are involved in enhancing a long term health benefits. M. olifera is among the most promising species...
Edwardsiella tarda was isolated from 47, 88, and 79% of skin, visceral, and dressed-fish samples, respectively. This species was also isolated from 30% of imported dressed fish, 75% of catfish pond water samples, 64% of catfish pond mud samples, and 100% of frogs, turtles, and crayfish from catfish ponds. The incidence of Edwardsiella increased during the summer months, as water temperatures in...
Generally, cultured fish are suitable in media with a pH of around 7, like mountainous river and borehole water. However, peat water is known low pH. It not for culture, especially fingerlings. This study was conducted to examine the survival African catfish fingerling (Clarias gariepinus) mixture different pHs. Survival test as subject applied bioassay method, LC50-96 hours. Peat agent arrange...
ABSTRACT For thousands of years, starting with detailed accounts from ancient Egypt, the African electric catfish (Malapteruridae) has been renowned for its ability to hunt and defend itself powerful shocks. Surprisingly, degree which are protected against their own or external shocks, how specific any protection would be species-specific waveform whether a discharging actively prepare onset hi...
This preliminary study was carried out to formulate high quality least-cost feed for the farming of African catfish (Clarias gariepinus Burchell 1822) in Sierra Leone. Locally sourced ingredients with vitamin premixes, lysine and methionine were used a 45% crude protein feeds catfish. Proximate contents determined practical compared two imported commercially produced (Ranaan Aller Aqua). Mean p...
Production traits such as growth, feed efficiency, survival, and fillet yield are economically important traits and an improvement in one or more of these traits will benefit the U.S. catfish farming industry. The U.S. Department of Agriculture (USDA) 103 line of channel catfish was developed jointly between the USDA Agricultural Research Service (ARS) Catfish Genetics Research Unit, Stoneville...
The fatty acid composition of farmed Tra catfish (Pangasius hypophthalmus) was determined and compared to farmed Atlantic salmon (Salmo solar) and to wild-caught Asian seabass (Lates calcarifer). Saturated fatty acids (SFA) were most abundant in catfish (42.6%) while salmon (37.2%) and seabass (39.0%) were rich in polyunsaturated fatty acids (PUFA). Tra catfish contains Docosahexaenoic acid (DH...
Six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. The thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. The impact resistance weight also varies fro...
