Description
技术领域
本发明涉及泥鳅养殖技术领域,具体涉及一种泥鳅的催孕方法。
背景技术
泥鳅属鲤形目,鳅科,泥鳅属。泥鳅广泛分布于我国辽河以南大部分地区以及越南、朝鲜和日本。我国各淡水水域,如湖泊、池塘、河溪、水沟、稻田等处都有这种鱼。泥鳅的生命力很强、繁殖快、饵料杂,是一种最易饲养又可获得高产的鱼类。泥鳅肉味鲜美,营养丰富,是一种高蛋白质、低脂肪的高档水产品,还含有脂肪、核黄素、磷、铁等营养成份被称为水中人参,在国内外市场深受欢迎。泥鳅药用价值很高,泥鳅其肉或全体均可入药,药材名泥鳅。其皮肤分泌的黏液也可供药用,药材名泥鳅滑液。泥鳅具有补中益气、壮阳利尿等功效,是外贸出口的主要水产品之一。它已成为庭院养殖、坑塘等小水面养殖的主要品种。但是泥鳅的养殖过程中仍然存在着不少问题,人工养殖中,泥鳅的抵抗力较弱,雄体的性能力不强,而雌体的发情期太晚,产卵时间晚,而且卵的受精率和孵化率都比较低。
发明内容
本发明所要解决的技术问题在于提供一种可以提高泥鳅雄体的性能力,提前母鼠的发情周期,提高受精率和孵化率的泥鳅的催孕方法。
解决技术问题采用以下的技术方案,
一种泥鳅的催孕方法,其特征在于:包括以下步骤,
(1)、选择健康的雌雄泥鳅作为亲本,配对为1雄陪3~4雌;
(2)、催产期确定,在人工饲养的中期5~6月份,晴天水温在20℃以上时进行,亲本泥鳅培育池中的泥鳅食量突然减少,抽样检查,可发现有的雌泥鳅腹侧已形成白斑点,表明人工催产时机已到;
(3)、催产期到后开始喂食带有催孕激素的***营养聊,所述的***营养料为麦麸40~50重量份、豆粕18~22重量份,玉米6~8重量份,鱼粉10~14重量份,血粉6~8重量份,酵母粉2.5~3.5重量份和孕酮1~2重量份,
在喂养***营养料的中期向雌体的腹部注射HCG1~2毫克。
在催产会雌体产卵后采用人工受精的方式,人工授精的地方应在室内,避开阳光直射。
所述的HCG与生理盐水来配制后使用。
本发明营养充分,通过孕酮与通常泥鳅的主食一起配合投喂,能够给泥鳅补充充足的能量,大大提高了雄体的性能力,提前雌体的发情期,又采用人工注射的方式对雌体进行催孕处理,人工受精,大大提高了产卵率,受精率和后期的孵化率。
本发明的有益效果是:本发明能提高泥鳅雄体的性能力,提前母鼠的发情周期,提高受精率和孵化率,从而提高经济效益。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施例,进一步阐述本发明。
一种泥鳅的催孕方法,包括以下步骤,
(1)、选择健康的雌雄泥鳅作为亲本,配对为1雄陪3~4雌;
