笔者结合生产实际,谈谈池塘养殖罗氏沼虾的生态环境:1.池塘的面积一般精养鱼塘面积0.53一0.67hm~2,水深2.5m以上,这与罗氏沼虾所需的生态环境有很大差异,因为罗氏沼虾喜欢底栖生活,喜欢栖息在池塘四周,尤其在晚上,都集中在沿岸摄食,并且喜欢打斗,霸占地盘。如果面积太大,池塘中间难以利用,但也不宜太小,太小,水环境不稳定,易缺氧,而罗氏沼虾的窒息点比家鱼要低,所以也不便养殖。罗氏沼虾养殖一般0.20—0.33hm~2,成东西走向,
The author combined with the actual production, talk about pond aquaculture Macrobrachium ecology: 1. Pond area generally intensive fish pond area of 0.53 a 0.67hm ~ 2, water depth of 2.5m above, and Macrobrachium Macrobrachium required ecological environment there The difference is great because Macrobrachium rosenbergii prefers benthic life and likes to inhabit ponds, especially in the evening, focusing on feeding along the coast and enjoying fighting and occupation of the site. If the area is too large, it is difficult to use the middle of the pond, but it is not too small or too small. The water environment is unstable and easily hypoxia. However, the suffocation point of Macrobrachium rosenbergii is lower than that of the fish, so breeding is not convenient. Macrobrachium rosenbergii farming generally 0.20-0.33hm ~ 2, into the east-west direction,
