Regional contributions using rearing technique

　MERI is also working on the breeding fishery organisms that can contribute to the development of the local industries. Currently, we are trying to rear short barbeled velvetchin, cherry salmon, and ivory shells that meet the following requirements.

Target species   ◎Short barbeled velvetchin: New local fish for aquaculture We began to develop aquaculture technique with local fishermen of Kashiwazaki city. We succeeded in seed production in 2017. This fish has good potential as a new aquaculture specie and can grow even at elevated water temperatures. Development of more stable production methods   ◎Cherry salmon: Seawater rearing technique We are conducting a breeding test of this species using both seawater and freshwater to explore the possibility of efficient land-based aquaculture. Development of promotion technique for smolt transformation   ◎Japanese ivory shells: Long-term rearing and resource management Ivory shells are an important fishery product in Kashiwazaki city, We try to storage shells collected in summer to winter season, little production in nature, for year round supply of this species.We also conducted research to enhance wild populations, such as setting artificial spawning substances and transplant of eggs.
