초록

무지개송어 품종개량의 일환으로 국내에 이식 양식되고 있는 미국산 무지개송어 발안난의 부화와 자치어 성장에서 얻어진 초기사육에 관한 기초적 시험을 실시하고 그 결과는 다음과 같다. 무지개송어 발안란의 난경은 $4.95{\pm}0.34\;mm$, 중량은 $0.07{\pm}0.003\;g$였다. 발안란은 8일째인 11월 25일에 전량 부화되었으며, 부화율은 평균 87.8%였다. 무지개송어 치어를 56일간 사육한 결과 전장 $4.0{\pm}0.7\;cm$로 매우 완만한 성장을 보였으며, 전장의 사육 경과일수에 따른 성장식은 TL=0.0366ED+1.8645 ($r^2=0.9285$, n=350)로 표시되었다. 부화된 치어의 평균 체중은 0.09 g였으며, 사육 $14{\sim}20$일째 $0.11{\sim}0.14\;g$로 서서히 증가되어 사육 41일째 0.33 g, 사육 48일째 0.45 g, 56일째 0.62 g로 급증되었으며, 체중의 사육 경과 일수에 따른 성장식은 $BW=0.0638e^{0.0408ED}\;(r^2=0.9917,\;n=350)$로 표시되었다. 치어의 56일간 사육 시 생존율은 $64.5{\pm}1.3%$였다.

This study examined the hatching rate of eyed-eggs and growth of fingerlings of USA strain rainbow trout, Oncorhynchus mykiss, which were transplanted on Nov. 17, 2005 from the USA for improvement of breeding. The diameter and weight of eyed-eggs were $4.95{\pm}0.34\;mm$ and $0.07{\pm}0.003\;g$, respectively. The eyed-eggs were hatched in 8 days later and hatching rates were $77.3{\sim}98.6%$. After 56 days from hatching, the fingerlings grew to $4.0{\pm}0.7$ cm and 0.62 g in total length and body weight, respectively. The relationships between total length (TL) and elapsed days (ED) were expressed as TL=0.0366ED+1.8645 ($r^2=0.928$, n=350). The relationships between body weight (BW) and elapsed days (ED) were expressed as following; $BW=0.0638e^{0.0408ED}\;(r^2=0.9917,\;n=350)$. And survival of rainbow trout was $64.5{\pm}1.3%$ in 56 days after hatching.
