苗种二次培育的概念最早在1985年的文献中提出,是室内外结合培育苗种的方式。单纯的室内水泥池育苗方式不受天气影响,可进行高密度育苗,前期仔鱼存活率较高;单纯的室外海水池塘育苗方式能提供仔稚鱼各发育阶段的适口饵料生物,鱼苗活动的空间大,生长快,体质健壮,育苗成本低。苗种二次培育技术就是有机地结合了前期仔鱼的室内水泥池高密度培育与后期仔稚鱼的室外海水池塘培育的优点,既解决了单纯室外海水池塘育苗成活率偏低的问题,又解决了单纯室内育
The concept of secondary breeding of seed was first put forward in the 1985 document, which is a way of combining seed cultivation with indoor and outdoor cultivation. Pure indoor cement pond nursery mode is not affected by the weather, can be high-density nursery, pre-larvae survival rate higher; simple outdoor seawater pond nursery approach can provide larvae of all stages of development of palatability bait organisms, fry large space for activity , Grow fast, strong physique, low cost of nursery. Secondary seedling cultivation technology is a combination of early larvae indoor cement pool high density cultivation and late larvae outdoor seawater pond cultivation advantages, both to solve the simple outdoor seawater pond seedling survival rate is low, but also to solve Pure indoor education
