초록

한반도에 출현하는 대황어 Tribolodon brandtii의 난 발생과 초기생활사를 연구하였다. 수정란은 난황이 황색이며, 약한 점착성을 가지는 구형의 침성란으로 평균크기는 $2.4{\pm}0.2mm$이었다. 수온 $20{\pm}1^{\circ}C$에서 부화 50%를 기준으로 60시간에 부화가 완성되었으며, 부화 직후 자어의 크기는 $6.4{\pm}0.4mm$이었다. 부화 10일 후 전장 $11.7{\pm}0.2mm$으로 성장하였고, 난황이 거의 흡수되었다. 부화 46일 후에는 전장 $19.6{\pm}2.7mm$로 성장하였고, 모든 지느러미 기조가 정수에 도달하였다. 부화 125일 후에는 전장 $54.9{\pm}15.8mm$로 성장하였고, 성어와 형태가 유사하였으며, 부화 236일 후에는 전장 $62.2{\pm}17.1mm$로 성장하였고, 체색이 성어와 유사하였다.

We investigated to egg development and early life history of Tribolodon brandtii in the Korean peninsula. The fertilized eggs of the T. brandtii were slightly adhesive and separated with a yellow yolk and no oil globule, and they was an average of $2.4{\pm}0.2mm$ in diameter. The hatching of the embryo took place in about 60 hrs after fertilization under water temperature of $20{\pm}1^{\circ}C$ and the newly hatched larvae were average $6.4{\pm}0.4mm$ in total length. At 10 days after hatching, they were average $11.7{\pm}0.2mm$ in total length and their yolk sac were completely absorbed. At 46 days after hatching, they became to juvenile stage and reached $19.6{\pm}2.7mm$ in total length and all their fin rays were formed. At 125 days after hatching, the juvenile were $54.9{\pm}15.8mm$ in total length and their body shape were similar to the adult fish. At 236 days after hatching, they fish were $54.9{\pm}15.8mm$ in total length and their body color were similar to the adult fish.
