根据全国水产技术推广总站发布的《2014年6月份全国水产养殖病害预测预报》,夏至后阴雨天增多、天气闷热,要特别关注池塘养殖中溶解氧的问题,水质调控格外重要。主要病害有:1.草鱼出血病主要发生对象为草鱼鱼种及1足龄青鱼,发病水温为20~30℃,在水温高于20℃时流行,25~28℃为流行高峰。湖北、湖南、广东、江西等草鱼主养区需重点防控。
According to “2014 China National Aquatic Diseases Prediction and Forecast” issued by the National Aquatic Technology Extension Station, the rainy days after the summer solstice increased and the weather was hot. Special attention should be paid to the problem of dissolved oxygen in pond aquaculture. The regulation of water quality is especially important. The main diseases are: 1. Grass carp hemorrhagic disease occurs mainly for grass carp species and 1 full-time herring, the onset of water temperature is 20 ~ 30 ℃, when the water temperature is higher than 20 ℃ epidemic, 25 ~ 28 ℃ for the epidemic peak.
