Abstract

This research is about spawning behavior and morphological development of the eggs and larvae of fringed blenny which lives in Korean sea. It helps to find out the relation between fringed blenny larvae and other stichaeidae larva. Moreover, it is going to use for the basic data of taxonomical research. There were 8 mother fishes (total length 31.8~34.0 cm, average $32.9{\pm}0.21cm$), which were captured from the cost of Sindeok-dong, Yeosu-si, Jeollanam-do from December, 2010. we used trap to capture them. Mother fishes were brought to glass aquarium ($50{\times}30{\times}35cm$) and nurtured with recirculate rearing system. Breeding water temperature was $12.3{\sim}15.8^{\circ}C$ (average $14.1{\pm}2.47$) and salinity was 32.5~33.5‰ (average $33.0{\pm}0.05$‰). fertilized egg was round, opaque demersal egg. The size was 1.81~2.19 mm (average $2.00{\pm}0.27mm$, n=50). Incubation was begun after 271 hours and 30 minutes from fertilization. It started with piercing the egg membrane. prelarvae had length of 8.45~8.84 mm (average $8.65{\pm}0.28mm$, n=5) right after the incubation, and both mouth and anus were opened. After 11 days from the incubation, postlarvae had length of 10.5~11.3 mm (average $10.9{\pm}0.57mm$), and the number of myotomes was increased to 66.

본 연구는 우리나라 연안에 서식하는 괴도라치의 산란행동 및 난 발생과 자어 형태발달을 조사하여 다른 장갱이과 어류자어와의 유연관계를 밝혀 분류학적 연구의 기초자료로 이용하고자 한다. 실험에 사용된 친어는 평균전장 $32.9{\pm}0.21cm$(31.8~34.0)로 2003년 12월 전남 여수시 신덕동 연안에서 원통형 통발을 이용해 8개체를 채집하여 실험실로 수송 후 사각 유리수조 ($50{\times}30{\times}35cm$)에 수용하여 순환여과식으로 사육하였다. 사육수온은 $12.3{\sim}15.8^{\circ}C$ (평균 $14.1{\pm}2.47$)를 유지하였고, 염분농도는 32.5~33.5‰ (평균 $33.0{\pm}0.05$‰)의 범위를 유지하였다. 수정란은 구형으로 백색의 불투명한 침성 점 착란이었다. 난의 크기는 1.81~2.19 mm (평균 $2.00{\pm}0.27mm$, n=50)이었다. 부화는 수정 271시간 30분 후 머리부터 난막을 뚫고 나오면서 시작되었다. 부화 직후 전기 자어는 전장 8.45~8.84 mm (평균 $8.65{\pm}0.28mm$, n=5)로 입과 항문이 열려있었고, 1개의 유구를 가지고 있었다. 부화 11일째 후기 자어는 전장 10.5~11.3 mm (평균 $10.9{\pm}0.57mm$)로 이 시기의 근절 수는 66개로 증가하였다.
