(一) 位置理想:利用地形、水源可靠,如建在河道、水库、渠道、山塘堰坝附近;灌排方便,时灌肘排,常有活水,以及旱不干涸,涝能排洪;无环境污染及水土流失;更不宜在苦楝树旁开挖,免致毒害鱼类;管理方便。 (二) 方向朝阳:以东西方向长、南北方向短的长方形为宜。这样日照时间长及受风面积较大,以增加水中溶氧,促使鱼类生长。 (三) 土壤选优:塘址土壤,壤土或砂壤土均可。但以壤土为好,保水保肥力强。为防塘底漏水,可用黄泥垫层夯实。只有保证不漏水,才能稳定水位、水质,保证增产。 (四) 水质良好:水质应无污染不含对鱼类有害
(1) The ideal location: the use of terrain, water and reliable, as built in the rivers, reservoirs, channels, hillside barrage; irrigation and drainage facilities, when the irrigation elbow row, often living water, and drought does not dry up, flood drainage; Environmental pollution and soil erosion; more should not dig the neem tree next to avoid poisoning fish; easy management. (B) the direction of sunrise: long in the east-west direction, short north-south rectangle is appropriate. This long sunshine and windy area to increase dissolved oxygen in water to promote fish growth. (C) soil selection: pond site soil, loam or sandy loam can be. However, loam is better, water and fertilizer and strong. To prevent the leakage of the bottom of the pond, available yellow mud cushion compaction. Only guaranteed watertight, in order to stabilize the water level, water quality, to ensure increased production. (D) good water quality: water should be non-polluting Does not contain harmful to fish
