                    泥鳅养殖过程中科学投喂的重要性

                    来源:www.athenaedgroup.com 分类:时间:2015-05-06

                      20XX年X月X日XXX市科技入户指导员XX、XXX到XX社区XX泥鳅养殖专业合作社走访,与养殖户进行了交流。

                      通过走访得知龙浦泥鳅养殖专业合作社近两年由于泥鳅行情的低迷,大多数养殖户都出现了不同程度的亏损,只有极少数养殖户有一点盈利,挣得一点辛苦钱。痛定思痛,不少养殖户改变了养殖模式,降低泥鳅苗种的放养量,改变饲料投喂次数,以求降低生产成本,有效应对泥鳅低迷的行情。夏季由于光照强,气温、水温高,鱼、虾摄食强度大,新陈代谢旺盛,水体中有机物质增多,发酵分解速度加快,致使水质发生重大变化。此时如果投饲量大,残饵会使水质迅速恶化,病原菌大量繁殖,引发多种鱼病,鱼摄食过量,尤其易患肠炎病。因此,养殖户要科学灵活适量投饵。从走访看,根据实际情况科学灵活适量投饵的养殖户今年基本都未有肠炎病的发生,而且这些养殖户同时把苗种放养量减少到去年的一半或者三分之二,投饵次数投饵量都大为减少,减少了残饵及粪便残留,通过科学调水等手段有效防控了水质的恶化造成的泥鳅生病。这样的结果改变了养殖户以往的养殖观念,不是投喂饵料越多泥鳅就长得越好,而是科学适量的投喂泥鳅会生长的更好,也不易生病,能获得品质更好地泥鳅。
