초록

줄가자미의 난발생 및 자치어 형태발달을 관찰하여 종자생산 및 분류학적 연구의 기초자료로 이용하고자 한다. 2017~2018년까지 동해안에서 어미를 채집하여 원형수조(Ø 6 ×1 m) 수온 12.8±1.9℃에서 사육하였다. 수정란의 크기는 1.42~1.59 mm (평균±SD, 1.51±0.04 mm, n=50)였고, 난의 형태는 구형의 무색 투명한 분리부성란이었다. 난발생 과정은 수정 60분 후 난황과 난막이 분리되었고, 62시간 후 배체가 형성되었다. 수정 144시간 후 전체의 50% 이상이 부화가 완료되었다. 부화 직후의 자어는 전장 4.22~4.64 mm (4.53±0.16 mm, n=10)로 입과 항문은 열리지 않았고, 부화 후 10일째 전기자어는 전장 5.88~6.62 mm (6.31±0.33 mm, n=10)로 난황 흡수가 완료되고, 입이 열리기 시작하였다. 부화 후 55일째 중기자어는 전장 10.4~13.3 mm (12.7±1.3 mm, n=10)로 척추말단 끝부분은 휘어졌다. 부화 후 120일째는 전장 35.3~40.5 mm (39.5±2.4 mm, n=10)였고, 각 지느러미 기조 수는 등지느러미 79~94개, 뒷지느러미 63~75개로 정수에 달하면서 치어기로 이행하였다.

Egg development and morphological change of larvae and juvenile of the Roughscale sole, Clidoderma asperrimum, were investigated in the present study. Adult fishes were collected on the East Sea, Korea, from 2017 to 2018 and reared in a circular water tank (Ø 6×1 m) at water temperature of 12.8±1.9℃. Fertilized eggs ranged from 1.42 to 1.59 mm (mean 1.51±0.04 mm, n=50) in diameter. The eggs were spherical in shape, transparent, floating and colorless. The egg yolk was separated from the egg membrane 60 mins post-fertilization (PF), and an embryo was formed in 62 hrs PF. More than 50% of the eggs hatched within 144 hrs PF in the range of 10.2~11℃(mean 10.8℃). The size of the newly hatched larvae were 4.22~4.64 mm (mean 4.53±0.16 mm) in total length (TL), their mouth and anus were not open yet. At 10 days after hatching, the preflexion larvae reached 5.88~6.62 mm (mean 6.31±0.33 mm) in TL, and the yolk absorption was completed and the mouth began to open. At 55 days after hatching the larvae reached to flexion larvae stage and they were 10.4~13.3 mm (mean 12.7±1.3 mm) in TL, and the tip of notochord was bent upward. At 120 days after hatching the larvae reached to juvenile stage and they were 35.3~40.5 mm (mean 39.5±2.4 mm) in TL. Their all fins had completed set of the fin-rays (D. 79~94: A. 63~75) and the juveniles adopted a benthic life.
