盐碱地区池塘水质复杂多变,矿化度高,营养盐类缺乏,水质清瘦,三毛金藻所分泌的毒素可引起鱼类的大量死亡,鱼病突出。加之养殖管理技术尚不完善,对盐碱池塘特有鱼病害的防治缺乏深入系统的研究,这将影响盐碱地的渔业开发。对其病害的防治主要应采取以防为主:①鱼种放养前,用漂白粉和石灰彻底清塘;②鱼种在拉网、运输和放养过程中,操作要小心谨慎,以免鱼体受伤,不用伤病、不健康的鱼种;③鱼种放养时要经药浴浸
Salt ponds complex and volatile water quality, high salinity, lack of nutrients, water quality, lean toxin secretion can cause a large number of fish dead fish, fish disease prominent. In addition, aquaculture management technology is still not perfect, and there is no systematic research on the prevention and treatment of endemic fish diseases in saline-alkali ponds, which will affect the development of fisheries in saline-alkali land. The prevention and control of its disease should mainly take precautionary measures as follows: ① before species stocking, thoroughly remove the ponds with bleaching powder and lime; ② fish species in the process of pulling the net, transport and stocking, the operation should be careful to avoid fish body injuries, No injuries, unhealthy species of fish; ③ fish species stocking to dip bath
