                    黄鳝养殖的错误认识

                    黄鳝养殖的错误认识

                    在黄鳝养殖过程中,有一些养殖户理所当然的认为其实是不对的,主要体现为:池水越少越好、粪肥越多越好、频繁的更换饲料等。

                    池水越少越好

                    若黄鳝频繁游至水面呼吸,影响正常生长,多是池水太深造成的。池养黄鳝水深宜在20厘米~30厘米左右,而网箱养黄鳝水草应尽量充满整个网箱,以便为黄鳝提供良好的栖息和呼吸条件。

                    粪肥越多越好

                    施粪肥极易败坏水质,诱发黄鳝疾病。

                    频繁的更换饲料

                    黄鳝吃饵料有一定的固定性,突然改变饵料种类,黄鳝会拒食,影响正常生活生长。如确实需要改换饵料,应逐渐减少原饵料的比例,同时增加新换饵料的比例来调整。
