해만가리비는 남해 해역에서 양식이 되고 있는 품종이다. 국립수산과학원은 동해 남부 해역에서 해만가리비 양식기술을 개발하고자 하였다. 산란 유도를 위해 간출자극과 <TEX>$23^{\circ}C$</TEX>로 조정된 수온자극을 실시하였다. 해만가리비의 산란량은 총 105,58 만 개 이였다. 수정률은 91.3%로 9,394 만 개가 수정되었다. 수정란은 원형으로 <TEX>$54.1{\pm}0.04-67.4{\pm}0.12{\mu}m$</TEX>로 평균 직경이 <TEX>$61.7{\pm}0.05{\mu}m$</TEX>이였다. 약 5일 후에는 초기원각 (prodissoconch shell) 을 형성하여 각정기 유생기 (umbo stage larva) 가 시작되며 각정 (umbones) 이 형성되었다. 약 8일후에는 <TEX>$150.4-204.8{\mu}m$</TEX> (평균 <TEX>$179.7{\pm}8.4{\mu}m$</TEX>) 크기의 부유유생이 되어 섬모가 있고 발 (foot) 과 안점 (eye spot) 이 생성되었다. 수정 후 10일 후에는 평균 각장 <TEX>$235.4{\pm}9.7{\mu}m$</TEX> 로 성장 하였으며 팜사나 경심망 등의 기질에 부착하여 부착치 패가 되었다. 치패 각장 성장은 22.71 mm 이였으며, 8월에 47.19 mm, 10월에 60.43 mm, 12월 72.40 mm 로 성장하였다. 전중량은 6월 이식 당시에는 2.0 g 이였으나 10월에 32.7 g으로 증가하였으며 12월에는 46.6 g 으로 증가하였다. 해만가리비의 일간 성장률은 각장의 경우, 4-6월이 0.35 mm/day, 6-8월 0.41 mm/day로 큰 폭으로 성장하였다.
Bay scallop (Argopecten irradians) has been farmed only in the South Sea of Korea. East Sea Fisheries Research Institute (ESFRI) has developed bay scallop aquaculture technologies to extend its aquaculture area to the Southeast Sea of Korea. For the artificial spawning, the water temperature was maintained at 23℃. Over 100,000,000 eggs were spawned through artificial spawning inductions, such as air exposure and thermal shock by rising the water temperature. The fertilization rate was over 91% with nearly 94,000,000 fertilized eggs. The shape of fertilized eggs was spherical with an average diameter of 61.7 ± 0.05 μm (54.1-67.4 μm). Five days after fertilization, the eggs developed into prodissoconch shell, and continuously grew into umbo stage and then umbones stage. After 8 days of fertilization, the size of larva became 179.7 ± 8.4 μm on average (150.4-204.8 μm), and the larva formed a foot and an eye spot. The larvae grew to 270.5 μm in 10 days and attached to adherence material, becoming juvenile bay scallop. The shells grew from 22.71 mm to 72.40 mm in 6 month (June-December). The total weight increased from 2.0 g to 32.7 g at the same period. The daily growth rates of young scallop were 0.35 mm d-1 (Apr. to Jun.) and 0.41 mm d-1 (Jun. to Aug.), which were comparable to those found in the South Sea. These findings suggest that the bay scallop aquaculture may be suitable in the Southeast Sea of Korea and may provide an additional crop to aquaculturists.
