今年夏季长时间的高温酷热干旱天气,给渔业生产带来严重影响。近期各地普降喜雨,旱情得到一定缓解,抓住当前的有利时机,切实搞好鱼种的秋季强化培育工作,是减轻损失,保障明年渔业生产照常发展的关键环节。 1、调整密度,分级饲养,适当稀养 选择合适的天气进行拉网筛选,将较大规格的(20cm以上)鱼种放到成鱼池塘中套养或另池饲养;15cm左右的中号鱼种按一般密度正常饲养;10cm左右的小规格鱼种放到水质条件较好、水源方便的池塘中进行强化培育,一般15m水深的池塘,亩放3000—5000
The prolonged hot and dry weather at high temperatures this summer has had a serious impact on fishery production. In recent years, there has been a steady stream of rain and rain relief. The drought has been eased. Seizing the current favorable opportunity and earnestly improving the cultivation of fingerling species in the autumn, it is a key link in mitigating losses and ensuring the normal development of fishery production next year. 1, adjust the density, grading breeding, appropriate selection of rare appropriate selection of the weather pull net screening, the larger size (20cm above) species into the adult fish ponds or feeding; 15cm or so medium-sized fish Species of normal breeding according to the normal density; 10cm small size of species placed on the water quality conditions are good, easy to carry out intensive cultivation of water ponds, generally 15m water depth of the pond, mu put 3000-5000
