초록

Morphological development of eggs, larvae and juvenile of the sunrise sculpin, Pseudoblennius cottoides were studed in the field and laboratory at the coastal Dolsan-do, Yeosu-shi from October, 2000 to April, 2001 Egg mass of Pseudoblennius cottoides in peribranchial cavity of Halocynthia hilgendorfi, were observed during late fall to winter in the study area. Fertiliged eggs were spherical in shape, demersal, adhesive, transparent and greenwish yellow color, measuring 1.84 mm (1.83-1.87 mm) in diameter. There were numerous and 17 (15-20) various-sized oil globules accounted in the yolk. Granular materials formed a mass in the yolk. Fertiliged eggs hatched at 301 hr 20 min after morula stage. Newly hatched larvae 6.31 mm (6.24-6.37 mm) in total length (TL), had a large yolk. At 3 days after hatching, the larvae, 6.77 mm (6.69-7.14 mm) in TL came out through the excurrent siphon of Halocynthia hilgendorfi. At 13 days after hatching, the larvae 12.59 mm (12.42-12.63 mm) in TL transformed to postlarval stage. At 32 days after hatching, postlarvae of TL 19.18 mm (19.01-19.46 mm) have reached the juvenile stage.
