在淡水鱼池中混养中国对虾,初看似乎很不可行。但沿海一带有很大一部分养鱼用水都含有一定的盐度,且比重一般都在1.002以上;而中国对虾却是广盐性的,从深海区的盐度30‰,到盐田水库的40‰,或近海河口附近的15—20‰,以至港湾河汉地区的2—3‰,都有不同时期的对虾存在。恰好我厂附近淡水常年比重在1.002左右,所以,我们
In the freshwater fish pond polyculture China shrimp, it seems at first sight is not feasible. However, a large part of the fish along the coast contain a certain amount of salinity, and the proportion are generally above 1.002; while the Chinese shrimp is widely salt, from the deep sea salinity 30 ‰ to Yantian Reservoir 40 ‰ , Or 15-20 ‰ near the estuaries, and 2-3 ‰ of the river and han area in Hong Kong. There are different stages of shrimp existence. Just around the year my freshwater proportion around 1.002, so we
