1984 A review of the effects of salinity on the early stages of fish is given, and methods used to study the effect of salinity on percentage of egg hatching and survival of Oreochromis niliticus (Linnaeus) larvae are described. Eggs of O. niloticus fertilized in a natural salinity of 2.1 %0 were tested for hatching and for survival of the large in five salinity concentrations of 5, 10, 15, 20 and 25 %0. Results show that successful egg hatching could be obtained at salinities up to 20 %0 . Tow lethal limits are also reported : at salinity 25 %0. for larvae hatched in salinities 5, 10 and 15 %0; and at salinity 30 %0 for those hatched in 20 %0. Both the two lethal limits were found to be extended to higher salinity by acclimation of the larvae.Al-Asgah, N.A; Bedawi, R.M.
1986 The use of carp fish for improving the quality of circulating sewage water.Al-Asgah, N.A; A.; Al-Ohaly, F.A; Al-Samil, A; Bedawi, R.M.
