暮春初夏时节,水体环境变化明显,做好水产养殖前期管理,对于全年的渔业生产至关重要。1.常规鱼类养殖对于上年存塘的鱼类,随着水温的回升摄食量逐渐增加,为加速鱼类生长,投饲应逐渐满足其需求。对于高产精养池因养殖密度较高,要注意观察“暗浮头”现象,严重时应及时采取加注新水或启用增氧机增氧。对于滤食性鱼类,应适当增加施肥量,以施发酵后的有机肥为好;
Late spring early summer season, significant changes in water environment, good pre-aquaculture management, the annual production of fisheries is essential. 1. Conventional fish culture For the fish kept in the previous year, food intake gradually increased with the rise of water temperature. In order to accelerate the growth of fish, feeding should gradually meet its needs. For high-yielding intensive breeding ponds due to high density, pay attention to observe the “dark floating head” phenomenon, in a timely manner should be promptly raised to add water or aerobic aeration. For filter fish, should be appropriate to increase the amount of fertilizer to ferment the organic fertilizer as well;
