锯缘青蟹的工厂化苗种生产过程中,后期稚蟹的中间培育通常在小型水泥池中进行。但在实际生产中由于受条件限制,育苗单位无法将大批量的稚蟹培育至大规格蟹种,而养殖单位则希望购买大规格苗种直接放养到大的养成池进行养殖,以确保产量与效益。因此,必须寻求培育大规格苗种的新的途径。本试验的目的就是为 During the production of industrialized seedlings of Marjoram, intermediate cultivation of late-stage young crabs is usually carried out in small-sized concrete ponds. However, due to limited conditions in actual production, nursery units can not breed large quantities of juvenile crabs to large-sized crab species, and breeding units hope to buy large-sized seedlings directly stocked into large ponds for breeding to ensure the production And efficiency. Therefore, we must seek new ways to cultivate large-size seedlings. The purpose of this test is
