我省商品鱼基地集中在洞庭湖区。湖区又是我省的重点粮食生产区,土地利用水平不断提高,农业肥料(特别是粪肥)已是不敷所需,农作物秸杆均用于建房、燃料、耕牛饲料等,几无废料可弃;加之远离城镇,交通不便,外来肥饲资源也匮乏。在这样的条件下发展基地高度集中的池塘养殖业,饲料和肥料的供应必须主要依靠基地本身,把解决饲料的基点放在每一个池塘及其周围的池埂上,即1亩水面及相配套的3分土地上。这是我省商品鱼基地普遍具备的生产条件。
Commodity fish base in our province concentrated in the Dongting Lake area. The lake area is also the key grain production area in our province. The land utilization level is continuously improving. The agricultural fertilizer (especially manure) is insufficient, and the crop straws are used for building houses, fuel, cattle feed and so on. Abandoned; plus away from the town, traffic inconvenience, external sources of fat feed is also scarce. Under such conditions, the supply of feed and fertilizers to develop highly concentrated pond aquaculture in the base area must rely mainly on the base itself, placing the feed-forward base on each pond and the ponds around it, that is, 1 mu of water surface and matching facilities 3 points on the land. This is our province commodity fish base generally have the production conditions.
