疾病也是制约小龙虾苗规格的一个主要原因,尤其以纤毛虫病最为常见。当纤毛虫在小龙虾苗体上寄生时,会从龙虾苗体上吸取营养而使龙虾苗身体瘦弱,小龙虾苗会因为缺乏营养而不能正常脱壳生长;还有当纤毛虫寄生在小龙虾鳃部时会影响小龙虾鳃的呼吸功能,导致龙虾幼苗不能正常呼吸而处于一个长期缺氧的状态,最终小龙虾苗会因为长期缺氧而不能正常摄食、脱壳和生长,导致规格偏小。另外由于纤毛虫的寄生甚至还会引起小龙虾苗其它疾病的发生而大量死亡,并且这样的成品虾进入市场后也没有消费者愿意购买。

近几年,由于受气候因素的影响,每年的春季都是干旱少雨,所以大部分养殖户在龙虾苗基地的水位都偏浅,但是随着气温的回升,投饵量的增加,其残饵、粪便以及池中有机物的分解都会给水质带来不良影响,这时又没有新鲜的外源水及时进行注换以调节水质,而水质的好坏将直接影响龙虾苗摄食、脱壳和生长,这些都制约着龙虾的长成规格。

在龙虾苗养殖过程中要采取捕大留小的方式,以降低池塘的养殖密度,不要指望等龙虾苗价格辽宁福彩35选7走势图高了以后再销售,因为即使市场价格再高,如果所养出的龙虾的规格太小,那也不可能卖出高价钱,相反,即使市场价格不高,只要小龙虾的规格大、品质好一样会卖出好价钱的。小龙虾具有攀附水草的习性,因此,在池中种植水花生、轮叶黑藻等水草,既可以为小龙虾提供脱壳隐蔽的场所,又可以增加小龙虾的生存空间而减少自相残杀的机会。
