국립수산과학원 동해수산연구소는 강원도 양양군 동산리 시험어장 해역에 해만 가리비 양식가능성 연구를 수행했다. 시험을 위한 이식은 6월에 수행되었으며 당시 치패 평균 각장은 <TEX>$5.79{\pm}0.6mm$</TEX>이였으며, 7월에 <TEX>$15.83{\pm}0.8mm$</TEX>, 9월에 <TEX>$39.40{\pm}0.7mm$</TEX>, 11월에 <TEX>$55.72{\pm}5.8mm$</TEX>, 12월에 <TEX>$59.67{\pm}1.7mm$</TEX>로 성장하였다. 이식 당시의 평균 각고는 <TEX>$6.06{\pm}0.7mm$</TEX>이였으며, 7월에 <TEX>$16.40{\pm}0.9mm$</TEX>, 11월에 <TEX>$53.16{\pm}5.2mm$</TEX>, 12월 <TEX>$55.80{\pm}2.9mm$</TEX>로 성장하였다. 전중량은 7월에 <TEX>$0.78{\pm}0.5g$</TEX>이였으나 11월에 <TEX>$24.25{\pm}4.2g$</TEX>으로 증가하였으며 12월에는 <TEX>$26.06{\pm}4.3g$</TEX>으로 증가하였다. 각장 일간성장율은 6월 0.33mm/day, 9월에 0.43mm/day, 11월에 0.13 mm/day를 나타내었다. 각고 일간성장율의 경우 6월 0.34mm/day, 9월 0.49 mm/day, 11월 0.09 mm/day를 보였으며 전중량 일간성장율은 7월 0.20 g/day, 9월 0.27 g/day, 11월 0.06 g/day를 보였다. 각고의 상대성장의 경우 y= 0.9132x, <TEX>$R^2=0.9923$</TEX>으로 성장하였다. 본 연구 결과로 동해 북부해역인 강원도에서도 해만가리비 양식 가능성이 입증되었다. 따라서, 동해안에서 큰가리비 단일 품종 양식의 단조로운 양식에서 벗어나 해만가리비 양식 산업 확대로 어업인의 소득증대에 기여할 것으로 사료된다.
NIFS conducted a feasibility study on the bay scallop Argopecten irradians aquaculture in the test site of Dongsan-ri, Yangyang-gun, Gangwon-do in June 2015. The transplantation for the test was also carried out in June. The average shell length was 5.79 ± 0.6 mm at the time, 15.83 ± 0.8 mm in July, 39.40 ± 0.7 mm in September, 55.72 ± 5.8 mm in November and 59.67 ± 1.7 mm in December. At the time of transplantation, the average shell height was 6.06 ± 0.7 mm, and it grew to 16.40 ± 0.9 mm in July, 53.16 ± 5.2 mm in November and 55.80 ± 2.9 mm in December. Total weight was 0.78 ± 0.5 g in July but increased to 24.25 ± 4.2 g in November and 26.06 ± 4.3 g in December. The daily growth rate of shell length(DGR) was 0.33 mm / day in June, 0.43 mm / day in September and 0.13 mm / day in November. DGR of weight was 0.20 g / day in June, 0.27 g / day in September, 0.06 g / day in November. The relative growth of shell length and shell height was y = 0.9132X and R2 = 0.9923. As a result, it was proved that bay scallop aquaculture is possible in Gangwon province, the northern part of the East Sea. This will definitely increase the income of fishermen by enabling them to culture more aquaculture species than the single large Patinopecten yessoensis in the region.
