抓好早春鱼塘管理,能促进鱼类提早开食恢复体质,增强抗病能力和提高成活率。1提高水温在适温范围内,鱼类会随着水温的上升而增加摄食,加快生长。因此,初春鱼塘水位应掌握在0.6￣0.8m之间,使水温能较快升高,以便能充分发挥肥效和促使鱼类提早开食。早春后要勤灌水,对保水力差的? Do a good job in early spring fish pond management, can promote the early recovery of fish to restore physical fitness, enhance disease resistance and improve survival. 1 to raise the water temperature in the temperature range, the fish will increase with the water temperature and feeding, accelerate the growth. Therefore, the early spring fish pond water level should be between 0.6 ~ 0.8m, so that water temperature can rise faster, so as to give full play to fertilizer efficiency and to promote early fish food. Early spring to ground irrigation, poor water retention?
