武昌鱼肉质细嫩,味道鲜美,且具有抗病力强,成活率高、草食性、放养周期较短与容易捕捞等优点,是一种优良的淡水鱼。我省是武昌鱼的发源地,养殖较普遍。但是各地养殖的武昌鱼,一般多作为搭配鱼放养,由于忽视了某些技术环节,加之其本身耗氧率较高,容易“浮头”致死,因而往往得不到预期效果。群众反映“武昌鱼好吃不好养”,就是这个道理。为了提高武昌鱼的养殖效果,现根据我们的实践体会并参考有关资料,谈谈武昌鱼养殖生产中几个应注意的技术要点。 一、繁殖时应注意提高鱼卵出苗率 5月中旬至6月中旬是武昌鱼进行人工催产的最适季节,可是此时水霉菌极易滋生,往往会导致鱼卵大批死亡。为了防治水霉菌的侵害,孵化时应把沾满鱼卵的棕榈皮鱼巢放入3％的食盐水中浸泡1—2分钟。
Wuchang fish tender meat, delicious, and has strong resistance to disease, high survival rate, herbivorous, short period of stocking and easy fishing, etc., is an excellent freshwater fish. My province is the birthplace of Wuchang fish, breeding more common. However, farmed Wuchang fish are mostly stocked with fish. Due to the neglect of certain technical aspects and the high rate of oxygen consumption, Wuchang fish are prone to “floating head” and often fail to achieve the expected results. The masses reflect “Wuchang fish is not good to keep”, this is the truth. In order to improve the breeding effect of Wuchang fish, now based on our practice and refer to the relevant information, talk about Wuchang fish farming several technical points should be noted. First, the breeding should pay attention to raising the sprouting rate of mid-May to mid-June Wuchang fish artificial seasons is the most suitable season, but at this time easy to breed water fungi, often lead to a large number of fish eggs died. In order to prevent the water mold fungal attacks, hatching should be covered with fish eggs palm nests into 3% salt water soak for 1-2 minutes.
