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 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 کاملUltrastructure changes in hepatocytes of catfish Clarias gariepinus from Lake Mariut, Egypt.
In the present study, specimens of catfish (Clariidae) were collected from a polluted location (Main Basin) and a relatively clean area (East Basin) in Lake Mariut, one of the Nile Delta Lakes in Egypt. Fifteen fish were taken from each site. Liver preparations of fish from the two sources were comparatively examined for cellular changes using transmission electron microscopy. Fish hepatocytes ...
متن کاملInduction of triploidy with caffeine treatment in the African catfish (Clarias gariepinus)
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...
