2013年入夏以来,由于天气变化频繁,水体理化因子的剧变、水体细菌的大量繁殖、气候干旱等原因,导致了在山东微山湖、东平湖沿湖黑鱼养殖区域出现以烂嘴、烂身、肝发白、花肝为主要症状的死鱼现象,笔者暂定义此病为肝胆综合症。此病流行快、死亡率高,危害大,无论大鱼小鱼、无论全冰鲜、全饲料还是半冰鲜半饲料喂养,均难幸免,死亡率多在20%以上,有的全冰鲜鱼投喂的塘口死亡率甚至全池死光,给沿湖的黑鱼养殖业带来较大的影响。笔者经过
Since the beginning of summer of 2013, due to the frequent weather changes, the drastic changes of physical and chemical factors of water bodies, the massive breeding of bacteria in water bodies and the climate droughts, etc., this led to the emergence of rotten mouths and rotten bodies in the blackfish farming areas of Weishan Lake and Dongping Lake along Shandong Province , Liver white, liver disease as the main symptoms of dead fish, I temporarily defined the disease as hepatobiliary syndrome. The rapid epidemic of the disease, the high mortality rate, endangering large, regardless of the big fish, whether full chilled, full feed or semi-chilled semi-fed, are unfortunate, more than 20% mortality rate, and some whole chilled The mortality rate of ponds fed by fish even died out completely, bringing great impacts to the blackfish farming along the lake.
