NIFS conducted a feasibility study on the bay scallop Argopecten irradians aquaculture in the test site of Dongsanri, 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.
