2001年春,渤海水域严重污染,育苗用海水多项指标超标。在此形势下,为改善水质,增强亲虾体质,促进卵巢发育及幼体成活率,我们在唐山丰南市毕中育苗场尝试使用“盛之丰”水产高效营养液。试验结果表明,该营养液在改善水质,增强亲虾抗病力,促进亲虾性腺发育,提高产卵率等方面有一定作用。1 材料与方法1.1 条件及设备 育苗场1988年投入使用,有效水体
In the spring of 2001, the Bohai Sea was heavily polluted, and many indexes of seawater for raising seedlings exceeded the standard. In this situation, in order to improve water quality, enhance broodstock physique and promote ovarian development and larval survival rate, we try to use “Sheng Feng” aquatic nutrient solution in BiZhong Seedling Farm in Fengnan City, Tangshan. The test results show that the nutrient solution has a certain effect in improving water quality, enhancing the disease resistance of broodstock, promoting gonadal development of broodstock, and raising the rate of oviposition. 1 Materials and methods 1.1 Conditions and equipment Nursery 1988 put into use, effective water
