"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 کاملOn cestode and digenean parasites of Clarias gariepinus (Burchell, 1822) from the Rietvlei Dam, South Africa.
Sharptooth catfish, Clarias gariepinus, from the Rietvlei Dam near Pretoria, South Africa were examined for internal platyhelminth parasites. Two adult cestodes, Polyonchobothrium clarias (stomach) (prevalence 71%, mean intensity = 5, n = 7) and Proteocephalus glanduliger (anterior intestine) (prevalence 14%, mean intensity = 2, n = 7), were found in the gut while metacercariae of one larval di...
متن کاملAffinity purification and partial characterization of IgM-like immunoglobulins of African catfish, Clarias gariepinus (Burchell, 1822).
IgM like macroglobulin from bovine serum albumin (BSA)-immunized African catfish C. gariepinus was purified by affinity chromatography and partially characterized. The molecular weight of this macroglobulin was 840 kDa, as estimated by gel filtration chromatography. Purified macroglobulin was analyzed using SDS-PAGE under reducing and non-reducing conditions. The molecular weight (MW) of heavy ...
متن کاملSurvival, growth, metabolism and behaviour of Clarias gariepinus (Burchell 1822) early stages under different light conditions
African catfish, Clarias gariepinus were exposed to total darkness (group D) or continuous light (L) during endogenous feeding. During external feeding some of the fish continued to be reared in darkness (DD) and some in light (LL), whereas two groups were exposed to reversed light conditions (groups DL and LD). Survival to the end of yolk absorption was 22% greater in fish exposed to darkness;...
متن کاملHistopathological Alterations in some Body Organs of Adult Clarias gariepinus (Burchell, 1822) Exposed to 4-Nonylphenol
Endocrine-disrupting chemicals (EDCs) include synthetic and naturally occurring chemicals that affect the balance of normal functions in animals (Razia et al. 2006). It has been found that exposure to natural and synthetic estrogenic chemicals may adversely affect wildlife and human health (Colborn et al. 1993). In vitro exposures (Soto et al. 1992; Soto et al. 1994; Toomey et al. 1999) have co...
