Effect of salinity on embryonic development, hatchability, and growth of African catfish, Clarias gariepinus, eggs and larvae



Effect of salinity on embryonic development, hatchability, and growth of African catfish, Clarias gariepinus, eggs and larvae



Journal of Applied Aquaculture 12(4): 89-93



Effects of salinity on embryonic development and growth of African catfish, Clarias gariepinus, eggs and larvae were studied. Eggs were incubated at 27-29 degrees C in 2, 4, 6, 8, and 10 ppt sodium chloride. Rate of embryonic development was delayed in all salt solutions by 15, 15, 28, and 30 minutes, in 2, 4, 6, and 8 ppt sodium chloride, respectively, when compared with the control group (0% salt). The total mortality occurred at 12 h after gastrula stage in the 10 ppt concentration.
