Abstract

This research investigated that the effect of water temperature on egg developmental stages of largescale blackfish Girella punctata and smallscale blackfish Girella melanichthys. The required times from fertilized embryos to hatching for the G. punctata were 67.8~37.5 hrs from 15 to $21^{\circ}C$, shorter as the water temperature increased. But fertilized embryos were dead after Kuffer's vesicle appearance stage at $24^{\circ}C$ and morula stage at $27^{\circ}C$. Biological minimum temperature (starting point for embryonic development) of the egg development was estimated to be $7.6^{\circ}C$ in average. In G. melanichthys, fertilized embryos were hatched within 61.2~38.3 hr from 15 to $21^{\circ}C$, the times were shorter as the water temperature increased to hatching, but its were dead on above $24^{\circ}C$. Biological minimum temperature of the egg development was estimated to be $6.5^{\circ}C$ in average. Based upon these results, it is recommended that the range of optimum water temperature for embryonic development of G. punctata and G. melanichthys is $15{\sim}21^{\circ}C$.

이 연구는 벵에돔 Girella punctata와 긴꼬리 벵에돔 Girella melanichthys의 인공종묘생산 기술개발을 위한 기초자료를 얻기 위해 자연산란 및 수온이 난 발생에 미치는 영향을 조사하였다. 벵에돔은 $15{\sim}21^{\circ}C$에서는 정상적인 난 발생의 진행과 부화가 이루어져서 부화까지는 67.8~37.5시간이 소요되었으며, 수온이 높을수록 각 난 발생 단계에 이르는 속도는 빨라졌다. 그러나 $24^{\circ}C$ 이상의 고수온 조건에서는 정상적인 난 발생이 진행되지 않았다. 이와 같은 결과는 긴꼬리 벵에돔에서도 비슷한 경향으로 $15{\sim}21^{\circ}C$에서 부화까지는 61.2~38.3시간이 소요되었고, 벵에돔과 같이 수온이 높을수록 난 발생속도가 빨라졌으나, $24^{\circ}C$ 이상의 수온 조건에서는 정상적인 난 발생이 진행되지 않았다.
