今年4月份以来,本刊记者就不断接到广东各地养殖户的报料电话,称自家养的草鱼出现不同程度的死亡,情况比往年严重得多,面对病害毫无应付的对策。为此,记者赶往珠三角和惠东,针对这两个地区的养殖情况一看究竟。草鱼病害肆虐种苗有价无市由于罗非鱼的市场行情跌宕起伏,国际出口市场又迟迟不给力,广东不少养殖户开始寻求新的出路,改变养殖模式,将罗非鱼与草鱼混养,或是精养草鱼,以此来降低养殖风险。据了解,今年罗非鱼整体的养殖密度减少一半以上,草鱼的养殖密度则增加了近三成。可偏偏市场难预测,今年养草鱼的人多了,市场上供过于求,直接导致鱼价的下跌。加上草鱼病害不断,难以根治,双重打击让不少养殖户愁了白发,对草鱼甚至心存恐惧,不知是否该继续养殖。
Since April this year, our correspondents have continuously received telephone calls from farmer households in Guangdong, claiming that their grass carp have been killed to varying degrees. The situation is far more serious than in previous years and there are no solutions to the disease. To this end, reporters rushed to the Pearl River Delta and Huidong, in view of these two areas of farming at a glance. Grass carp epidemic raging seedless prices due to tilapia market ups and downs, the international export market has yet to delay, many farmers in Guangdong began to find a new way to change the breeding mode, the tilapia and grass carp mixed Raise, or intensive grass carp, in order to reduce the breeding risk. It is understood that the overall breeding density of tilapia reduced by more than half this year, grass carp breeding density increased by nearly 30%. However, the market may be difficult to predict this year, many people raise grass carp, the market oversupply, a direct result of falling fish prices. Coupled with grass carp disease continued, difficult to cure, double hit so many farmers worry about white hair, grass carp even fear, I do not know whether to continue farming.
