INTRASPECIFIC HYBRIDIZATION AND RECIPROCAL CROSS BETWEEN CULTURED AND WILD Clarias gariepinus; AND EVALUATION OF THEIR PROGENIES

AbstractStudies of intraspecific hybridization and reciprocal cross between cultured and wild Clarias gariepinus and evaluation of their progenies was carried out, with aim of evaluating the progenies of the crosses hatchability, survival, growth etc. Pure strains of cultured and wild Clarias gariepinus broodstock were used. Incubation, hatching, and post hatching activities were monitored in 50 litres plastic bowls. Cultured Male Clarias gariepinus (CCG♂) x Wild Female ...

Proximate and Macro Element Composition of Four Fish Species from Lower River Benue Makurdi Benue State Nigeria

A study was conducted on four fresh water fish species: Protopterus annectens, Labeo coubie, Auchenoglanis occidentalis and Mormyrus rume from lower river Benue, Makurdi to determine the proximate and macro elements composition of these fish species from lower river Benue Makurdi. A total of 600 fish samples were collected, 50 samples from each species for the period of three months. Fish samples were collected and transported to the University of Agriculture Makurdi, Department of Fis...

Molecular Mechanisms of Natural Carotenoid-based Pigmentation of Queen Loach, Botia dario

The genetic basis and expression patterns of key genes are important aspects of study to understandthe colouration. This trait differs between wild and domesticated fish which is a matter of research.Botia dario is an indigenous fish, having ornamental and aesthetic value, which shows faded appearancein terms of colour in domesticated condition than wild. In the present study the carotenoid-fed B. dariowere examined through incorporation of marigold petal meal in the diets at the rate of 5, 1...
