Male-male competition is a component of Darwin’s theory of precopulatory intrasexual selection, where males compete for access to resources important for reproduction and successful males pass on traits that endow greater competitive ability to their offspring, thereby exaggerating the trait(s) over evolutionary time. Metals, such as lead (Pb) ofte...

This study assessed the suitability of Random Amplified Polymorphic DNA (RAPD) technique for the characterization of Oreochromis niloticus, Heterobranchus longifilis, and Heterotis niloticus from the Niger-Benue River confluence in Lokoja, Kogi State, Nigeria. RAPD-Polymerase Chain Reaction amplifications reactions were carried out on DNA extracted...

Aquatic environment with its water quality is considered the main factor controlling the state of health and disease in both cultured and wild fishes. Heavy metals have WHO limit, above which are toxic, some toxic effects include: reduced growth and development, cancer, damaged to nervous system and in extreme cases death. The present study analyze...

Fish protein is regarded as quality protein being rich in essential amino acids with a high digestibility value. The biochemical composition of the fish differs with the change in habitat as well as season. Samples of freshwater catfish (Clarias gariepinus) from Upper Jebba Basin, Nigeria were analyzed during the dry and wet seasons to study the va...

This study investigates the nutritional and phytochemical composition of some selected aquatic plants to serve as indexes of nutritional values for both domesticated aquatic and terrestrial animals. Freshly harvested Nympheaa lotus (water lily), Pistia stratioties (water lettuce), Eichorrnia crassipes (water hyacinth) and Ipomoea aquatica (water sp...

As Fish farming (Aquaculture) is the most efficient husbandry method for animal protein production, an assessment of catfish farming in Osogbo and Osun state was undertaken. An assessment was carried out among 53 catfish farmers between January and April, 2013 using questionnaires conducted via face-to-face interviews. The results revealed that the...

Wild plants offer a convenient but cheap means of providing adequate supplies of nutrients to man and animals living within the tropics but the availability of these nutrients after ingestion depends on nutritional quality of the plant even when tested within one fish species. Considering the significance of quality data needed for the development...
