随着养鱼事业迅速发展,苗种培育成为关键性因素之一,然有些养鱼户对鱼苗何时下塘往往掌握不好,不但影响鱼苗的生长,而且也降低了鱼苗的成活率。肥水下塘的生物学原理是浮游生物发育规律和鱼类在个体发育中食转化规律的一致性。 With the rapid development of fish farming, the cultivation of seedlings has become one of the key factors. However, when some fish farmers are not familiar with fish ponds and ponds, they not only affect the growth of fry but also reduce the survival rate of fry. The biological principle of fertilizer ponds is the consistency of plankton development law and the law of food conversion in individual development.
