一、整治改造鱼塘。在春放之前,务必因地制宜把鱼塘、山塘等小水面适当扩大到5亩至10亩之间,尤其常年水深保持在2米以上,加高加固塘基,修好塘闸,能排能灌,这是养鱼“三高”的基础工作。 First, rehabilitate fish ponds. Before spring release, it is imperative to appropriately expand the small ponds, ponds and other small water surfaces to between 5 and 10 mu depending on the local conditions. In particular, the perennial water depth should be maintained at over 2 meters. The ponds should be heightened and reinforced, and the pond gates repaired. This is the basic work of raising fish “three highs.”
