متن کاملOntogeny of Swimming Movements in the Catfish Clarias gariepinus
The swimming movements of C. gariepinus larvae were recorded with a high-speed camera (400, 500 and 800 fps) from 0 to 336 hours post-hatching. Movements of adult fish were also recorded to provide information on the last developmental stage. Seven landmarks positioned on the fish midline were used during tail beating to determine various parameters during ontogeny and, on the basis of these pa...
متن کاملGrowth Performance and Economic Benefits of Oreochromis Niloticus/clarias Gariepinus Polyculturefed on Three Supplementary Feeds in Fertilized Tropical Ponds
An experiment was conducted for 180 days at Sagana Fish Farm, Kenya, to evaluate the performance of two formulated pellet feeds and a locally available rice bran. A polyculture of Oreochromis niloticus and Clarias gariepinus in fertilized tropical ponds was used. Twelve 800-m2 ponds were used, and each pond was limed at a rate of 20,000 kg ha-1 and stocked at a rate of 19,375 ha-1 with sex-reve...

Glyphosate is one of the most popular herbicides used by farmers in Kano because of its active reaction on killing weeds without affecting th...
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...
