目前,南方有些农民养鳝鱼,主要是在屋顶养殖。现将有关技术介绍如下:1.修建鳝池:在水泥平屋顶,用砖砌成高80～100厘米的围墙,屋顶、围墙均用水泥抹平。鳝池面积以20～30平方米为宜,排水口用铁丝网拦好。池底铺一层盖房用的筒瓦或直径10厘米左右的大竹筒,也可用三块砖搭一个通道,便于鳝鱼栖息。通道之间距离一般为15～20厘米,然后覆盖厚30厘米的肥泥,也可以直接在池底放20厘米厚肥泥,再灌进高出泥面30～40厘米的水,投放少量麦秆、浮萍,以便于鳝鱼 At present, some farmers in the south raise salmon, mainly on the roof. Now the relevant technology is introduced as follows: 1. Construction of Dianchi Lake: On the flat roof of cement, bricks are used to form a wall of 80 to 100 cm in height, and the roof and surrounding walls are plastered with cement. The area of ​​Dianchi Lake is suitable for 20 to 30 square meters, and the drain outlet is blocked with barbed wire. The bottom of the pool is covered with a layer of tiles or a large bamboo tube with a diameter of about 10 centimeters. It is also possible to use three bricks to provide a passage for the roach. The distance between the passages is generally 15 to 20 centimeters, and then covers 30 centimeters thick fertilizer. You can also put 20 centimeters thick fertilizer directly in the bottom of the pool, and then poured into the water 30 to 40 centimeters higher than the mud surface, put a small amount of wheat Stalks, duckweed, to facilitate the carp
