鱼类的胚胎发育,要求生态环境具有适宜的pH值。babacKnn(1930)在探讨鱼类胚胎发育与环境pH值的关系时指出,在实验条件下,小体鲟(Acipenser ruchenus L.)胚胎和鱼苗阶段的最适pH值分别为6.4—7.5和6.1—8.0,如pH值范围变动在6.1—6.4或7.5—8.0时,其胚胎发育出现畸形的比例显著增加。Kwain(1975)发现,当pH值低于4.5时,虹鳟(Salmo irideus Gibbons)鱼卵无法生存。Dahl(1927)认为,鳟鱼(Salmo trutta L.)仔鱼在
Fish embryonic development, requires the ecological environment has a suitable pH value. BabacKnn (1930) in discussing the relationship between fish embryo development and environmental pH value pointed out that under the experimental conditions, the optimum pH value of the embryo and fry stage of small-body sturgeon (Acipenser ruchenus L.) were 6.4-7.5 and 6.1- 8.0, such as the pH range changes in the 6.1-6.4 or 7.5-8.0, the proportion of embryonic development deformity increased significantly. Kwain (1975) found that fish eggs of Salmoirideus Gibbons could not survive at pH values below 4.5. Dahl (1927) argues that trout (Salmo trutta L.) larvae are present
