Abstract
Greeling, Hexagrammos otakii Jordan et Starks is commonly found at the coastal waters of Korea and Japan. The authors carried out the artificial insemination in the laboratory on Dec, 17, 1987, and reared the hatched larvae in an aquarium. The eggs were demersal and adhesive, and their diameters were 2.00~2.15mm. Color of yolk was light yellow in the early stage, and then turned to orange before hatching. The yolk had numerous tiny oil globules. Hatching began about 477hours after insemination under water temperature of
1987년 12월에 부산시 남구 민락동 활어공판장에서 쥐노래미의 성숙한 친어들을 구입하여, 건도법(乾導法)에 의해 인공수정(人工受精)한 후 난발생과정(卵發生過程)과 이들 난(卵)에서 부화(孵化)한 자어(仔魚)들을 사육하면서 형태발달과정(形態發達過程)을 관찰하였다. 1. 난(卵)은 침성점착난(沈性粘着卵)으로 크기는 2.00~2.15mm(평균, 2.07mm)로 많은 유구(油球)를 가지고 있다. 2. 사육수온
