Effect of Dietary Vernonia Amygdalina Del. Supplementation on Some Biological Parameters of Milt of Male African Catfish (clarias Gariepinus)
The effect of Vernonia amygdalina Del. leaves on the reproductive potential of male Clarias gariepinus was investigated using 56 fish (425±75.7 g). Four diets with crude protein level of 45% were formulated with different inclusion levels of V. amygdalina leaves. The leaves were added to the basal diet at 0% (control), 5%, 10% and 15% inclusion levels. The 56 male C. gariepinus were randomly di...
متن کاملHistopathological Effects of Glyphosate on Juvenile African Catfish (Clarias gariepinus)
Most aquatic herbicides have undergone some toxicity testing for effects on non-target aquatic organisms, little of this testing has been conducted on early life stages of Clarias gariepinus. African catfish C. gariepinus were exposed to acute concentrations of glyphosate for 96hrs. The lethal concentration (LC ) 5O value of glyphosate was 0.295 mg l for 96h of exposure. The mean mortality perc...
متن کاملThe effect of extract of bitter leaf (Vernonia amygdalina) on blood glucose levels of diabetic rats
Twenty-four (24) adult albino Wistar rats (twelve males and twelve females) were used for the study. The animals were divided into six groups of four rats in each. Proximate analysis was carried out on the plant sample with the following results: crude protein 22.45 ± 0.01%; crude fat (3.45 ± 0.0%); crude fiber (16.0 ± 0.0%) and Ash (9.95 ± 0.2%). Quantitative phytochemical analysis revealed th...
متن کامل"Toxic effects of 4-nonylphenol on the embryonic development of African catfish Clarias gariepinus (Burchell, 1822) ''
The present study investigated effects of environmental relevant concentrations of 4-nonylphenol (0.05 to 0.08 to 0.1 mg/l) on the reproduction and embryonic developmental stages of catfish (Clarias gariepinus). To determine the effect of 4-nonylphenol on reproduction; catfish were exposed to three concentrations of 4-nonylphenol in a flow-through-system during spawning period (some for one wee...
متن کاملEffects of testosterone propionate on growth, survival and sex-ratio of african catfish (Clarias gariepinus Burchell)
For studying the effects of different levels of testosterone propionate on growth, survival and sex-ratio, five different doses such as 125, 100, 75, 50, 25 mg hormone per kg feed were administered to 5-day old Clarias gariepinus fry through diet for a period of 40 days. The growth performance in terms of weight and length gain of the fry receiving 100 and 75 mg hormone per kg feed were signifi...
