Abstract

本发明提出了一种抗病鲈鱼养殖方法，包括如下步骤：S1：选择宁静安全的环境修建池塘，池塘的面积以8‑12亩、水深2‑3m，每1.2‑1.5亩水面配备l台增氧机；S2：将池塘干塘、清淤和曝晒，放苗前14‑16天用生石灰70‑80kg/亩进行消毒；S3：淡化鱼苗；S4：日常喂养：每天给鱼苗投食饲料并检查养殖池内环境，每隔一周给养殖池换水，高密度鲈鱼养殖会带来塘底大量的残饵和排泄物，有害物分解浓度高，大量消耗水中氧气，尤其是高温天气更为严重，这是鱼病产生的重要原因，添加草木灰、亚氯酸盐、沸石粉等组分提高残饵和排泄物的分解效率，降级对水体中氧气的消耗，避免鱼病的爆发，净化水质，增加水体含氧量，提高鲈鱼单位面积产量以及个体净重。

Description

一种抗病鲈鱼养殖方法
技术领域
本发明属于水产养殖技术领域，特别是指一种抗病鲈鱼养殖方法。
背景技术
加州鲈鱼(学名：Micropterus salmonides)原名大口黑鲈，分类学上属鲈形目，太阳鱼科。原产地是在美洲的淡水湖泊中，在二十世纪八十年代左右引进我国。它肉质鲜美、且繁殖迅速，因此许多的渔业养殖户还是比较喜欢它的。它是一种肉食鱼类，会吞吃鱼类、小虾等水中的生物。
但随着养殖规模的扩大，加州鲈鱼的病害问题日益凸显出来，其疾病主要有弹状病毒病、虹彩病毒病、诺卡氏菌病、迟缓爱德华氏菌病、车轮虫病等。
在加洲鲈鱼的精养过程中，要想增快其生长速度及提高成活率，进行驯饵是关键，只有经过驯化喂养人工配合颗粒饵料，才能使鱼不致互相残食和由于追食活鱼而过多地消耗体能，而影响生长速度。
发明内容
本发明的目的在于提供一种能够提高螃蟹产量，并同时收获鱼和植物产品的生态鱼蟹养殖方法。
本发明的技术方案是这样实现的：
一种抗病鲈鱼养殖方法，包括如下步骤：
S1：选择宁静安全的环境修建池塘，池塘的面积以8-12亩、水深2-3m，每1.2-1.5亩水面配备l台增氧机，池塘设进、排水闸，分别通向进、排水河，不重复使用养殖水，以免二次污染；
S2：将池塘干塘、清淤和曝晒，放苗前14-16天用生石灰70-80kg/亩进行消毒；
S3：淡化鱼苗：将从海区捕捞的鱼苗淡化至盐度4-7％后投入池塘内；
S4：日常喂养：每天给鱼苗投食饲料并检查养殖池内环境，每隔一周给养殖池换水；
优选的，饲料包括如下重量份的组分：膨化大豆20-35份、小麦粉15-25份、稻糠10-20份、花生粕12-20份、鱼粉10-20份、蚯蚓粉20-30份、海藻粉6-10份、发酵血粉8-15份、草木灰8-13份、沸石粉8-15份、亚氯酸盐0.2-0.4份、益生菌0.04-0.08份、豆油4-6份、丁香酸0.4-0.6份、甜菜碱0.5-0.8份、柠檬酸0.8-1.2份、双乙酸钠3-5份、肌醇0.2-0.4份、黄原胶1-1.8份、聚丙烯酸钠1.5-2.5份、生物制剂3-5份。
优选的，所述生物制剂包括以下重量份的原料：氨基酸5-7份、乳酸菌1-3份、曲霉2-5份、酵母菌3-6份、果胶2-5份、丝状真菌5-12份、赤霉素2-5份、醋酸菌6-9份、芽孢杆菌2-4份、活性炭颗粒6-10份。
优选的，定期向养殖塘中施放光合细菌菌剂。
优选的，每天利用水体增氧装置对池塘水增氧2小时。
优选的，所述的应用可用于鲈鱼的夏季和秋季养殖，当鲈鱼为15-100g时，饲料的粒径为1-2mm；鲈鱼为100-300g时，饲料的粒径为2-3mm；鲈鱼为300-500g时，投饲料的粒径为3-4mm；鲈鱼为＞500g时，饲料的粒径为4-5mm。
综上所述，本发明的优点在于：
本发明的一种抗病鲈鱼养殖方法，高密度鲈鱼养殖会带来塘底大量的残饵和排泄物，有害物分解浓度高，大量消耗水中氧气，尤其是高温天气更为严重，这是鱼病产生的重要原因，添加草木灰、亚氯酸盐、沸石粉等组分提高残饵和排泄物的分解效率，降级对水体中氧气的消耗，避免鱼病的爆发，净化水质，增加水体含氧量，提高鲈鱼单位面积产量以及个体净重。
