Method for improving disease resistance of micropterus salmoides by using cobra antibacterial peptide

The invention discloses a method for improving disease resistance of micropterus salmoides by using cobra antibacterial peptide, which comprises the following steps: feeding the micropterus salmoides with compound feed added with 0.5%, 2.5% or 5% of cobra antibacterial peptide, observing and recording the health condition, initial illness time, illness condition, body surface characteristics, healing condition and death condition of the micropterus salmoides every day in the breeding process, and determining the disease resistance of the micropterus salmoides. And the disease resistance of the micropterus salmoides is verified to finally obtain that the growth speed and the antipathogen ability of the micropterus salmoides can be improved by adding the cobra antibacterial peptide, and when 2.5% of the cobra antibacterial peptide is added, the effect is optimal, and the cost performance is highest. 本发明公开了一种利用眼镜蛇抗菌肽提高大口黑鲈抗病能力的方法，对大口黑鲈投喂添加了0.5%、2.5%或5%眼镜蛇肽抗菌肽的复合饲料，在养殖过程中，每日观察并记录大口黑鲈健康情况，初始生病时间、病况、体表特征、病愈情况和死亡情况，
