大分县浅海渔业试验场,自1962年用车虾养殖池捕纳天然幼蟹进行养殖,或翌年采捕抱卵的亲蟹培育三疣梭子蟹苗。在试验水池培育亲蟹产卵化苗是成功重要环节,此后还进行国家指定的培苗量的研究。这个项目现在正研究提高亲蟹质量防止相互残杀、抢食等问题。因现在还不能大量生产,所以试验研究单位到渔协都推广研究育苗技术。从1980年开始计划对稚蟹放流养殖。用大型水池培育稚蟹的数量,过去每吨水体培育两千
Oita shallow-sea fishery experimental field, since 1962 car shrimp farming ponds to catch natural crabs for breeding, or catch the next year, holding the eggs of the crab breeding Portunus trituberculatus. Crab spawning in the experimental ponds is an important part of the success of the successor, but also for the state after the study of the amount of seedlings. This project is now studying the issue of raising the quality of crabs to prevent each other from killing each other and eating it. Due to the current mass production can not yet, so the pilot research unit to the fisheries Association to promote research nursery technology. From 1980 onwards plan to put the flowering of baby crabs. The number of juvenile crabs nurtured in a large pool grew 2,000 in the past
