説明

The eggs of Gymnocanthus herzensteini were fertilized and cultured for the study of their embryonic and larval development.The eggs were demersal and adhesive.The yolk was light orange in color with a single large oil globule, sometimes accompanying a few small oil globules, and contained a mass of many small granular materials.Melanophores and xanthophores appeared on the embryonal body after the mid-stage of embryonic development, but not on the yolk and oil globule.Hatching occurred between 42 and 49 days after fertilization at the water temperature 5.5°-6.8°C.<BR>The newly hatched larvae averaged 5.83 mm in body length with 41-43 pairs of somites.The prominent characteristic of larvae lay in the pigmentation pattern of melanophores and xanthophores on the nape, the crown of the head, the body cavity, and especially on the ventral margin of the tail portion.After thirty-nine days, the larvae reached an average body length of 7.84 mm.The pigmentation pattern remained essentially unchanged except the appearance of melanophores on the lower jaw and the opercle region.Various body parts were measured to examine the changes in body form in the larval stage.
