条纹锯(鮨)胚胎发育及卵黄囊仔鱼形态变化的观察
Preliminary studies on embryonic development and morphology of the yolk-sac larvae of Centropristis striata Linnaeus
摘要
Abstract
Nikon E200 microscope was used to observe the embryonic development of Centropristis striata Linnaeus. Detailed changes from the fertilized egg to the newly hatched fish, and morphological characteristics of 26 specific developmental stages were described. The results showed that fertilized eggs of C. striata Linnaeus were free-floating and spherical, at an average diameter of 0. 950 + 0. 039mm; Embryonic development C. striata Linnaeus experienced six main stages including cleavage, blastocyst,gastrulation, neurula embryo,organogenesis and hatching stage. The results showed that, at water temperatures of 20~20. 5 ℃, salinity 28~32, 5mg/L,and pH 7. 6~8. 4, fertilized eggs of C. striata maintained in cages with slight areation were hatched in 47 h,and yolk-sac in the larvae disappeared after 2 days.关键词
