As filter feeders, scallops do not require feed input, thereby posing no fishing pressure on wild stock.
Since scallops are filter feeders, there is no impact on the aquatic ecosystem. Scallops are susceptible to viral and bacterial diseases. However, disease-outbreak impacts have not been found in Japan for the last decade. No evidence of chemicals is used in the grow-out system. Scallop farming has a high-risk escape, but the ecological impact is low as the species is caught in the wild and native to the region.
Aquaculture activities are regulated under the Fisheries Law and administered by the Ministry of Agriculture, Forestry and Fisheries (MAFF), but are managed and controlled by Fisheries Cooperative Associations (FCAs) at a regional level. Japanese management mainly address most issues like disease control, marine spatial planning (MSP), and integrated coastal zone management (ICZM). The Japanese regulatory framework regarding scallop farming is largely effective.
