海涂围滩养鱼投资省,周期短,效益高,近年来,已在各地纷纷兴起,成为一种行之有效的开发利用形式。海涂围塘养鱼一般是在海堤内的荒滩或低产滩地上,人工挖沟筑埂,引灌淡水形成滩塘。滩塘面积较大,通常每个滩塘水面在10～60公顷不等;水层较浅,中间滩面仍为原始荒滩;土壤盐分重、瘠薄,滩面生长着芦苇、茅草及一些蒿草,注入淡水后,芦苇等挺水植物生长繁茂。现就我们在多年的生产实践中积累的一些经验介绍如下: 一、鱼种放养
In the recent years, it has risen in various places and become an effective form of exploitation and utilization. Sea Turtle pond fish are generally within the seawall in the wasteland or low-yielding land, artificial ditching to build 埂, dredging freshwater to form Tan Tong. Beach ponds are large in area, usually ranging from 10 to 60 hectares in each beach pond; the water layer is shallow and the middle beach surface is still the original wasteland; the soil is heavy and infertile, and the beach surface grows reeds, thatch grass and some Artemisia Grass, injected fresh water, reeds and other emergent plants grow lush. Now we have accumulated in the many years of production experience accumulated as follows: First, stocking
