Abstract

This study has been conducted to develop the techniques for spat production of the sun and moon scallop from January 1995 to December 1996. With the adult scallops collected from the Sogwipo area, spawning induction and larvae rearing were attempted several times and monthly changes of GSI were also monitored during the experimental period. The results obtained wre as follows. 1. GSI started to increase from June and showed the maximum value of 22.17 and 14.98 in female and male respectively in November, and then gradually decreased from December. 2. Spawning induction by heating method turned out to the most efficient way showing the responding rate of 64.8~91.5%. The responding temperature was $21.4~26.4{\circ}C$ which was $3.1~8.5{\circ}C$ increased from the rearing temperature of $16.3~18.3{\circ}C$. An average number of eggs spawned was $9.2{\times}10^5$ 3. the average size of eggs after fertilization was about $72{\mu}m$ in diameter. The first polar body discharge, blastula formation, and trochopore larvae appearance occurred 30 mininutes, 18 hours, and 22 hours after fertilization respectively. 4. Settling rates in various collectors were similar one another, whereas pouring larvae in the mesh was the most efficient way for larval setting. 5. The spates grew to be 1mm in their shell length for the first 50 days after fertilization and 9.6mm in 135days. 6. Correlation between shell length (SL) of the spat and the number of days (X) after spat settlement could be expressed as $SL=257.75e ^{0.0272x}$(r=0.9100).

해가리비 종묘생산을 위하여 1995년 1월부터 1996년 12월까지 서귀포 연안에서 가리비를 어획하여 GSI, 산란유발 및 유생사육실험을 실시한 결과를 요약하면 다음과 같다. 1. GSI는 암, 수모두 7월부터 증가하기 시작하여 암컷은 11얼에 22,17, 수컷은 14.98로 최고치를 보인 수 점차 감소하였다. 2. 산란유발률은 가온자극법에서 64.8~91.5%로 반응률이 높게 나타났으며, 반응수온은 사육수온($16.3~18.3{\circ}C$)에서 $3.1~8.5{\circ}C$ 상승된 $21.4~26.4{\circ}C$ 였으며, 개체당 평균 산란량은 $9.2{\times}10^5$개였다. 3. 난은 분리침성란이었으며, 크기는 $72{\mu}m$였고, 수정 30분후 후 제1극체가 방출하였으며, 18시간후 포배기, 22시간이 경과하면서 담륜자 유생으로 되었다. 4. 채묘자재별 부차율은 별 차이가 없었으나 채묘방법에서는 그물망에 유생을 주입시키는 방법이 다른 시험구에 비해 현저하게 많아 부착하였다. 5. 부착기 이후 자패의 성장은 수정후 50일때에 약 1 mm, 135일 경과하면서 9.6 mm로 성장했으며, 부착기 이수 경과일수(X)에 대한 각장의 성장은 $SL=257.75e ^{0.0272x}$(r=0.9100)의 지수곡선식으로 나타났다.
