摘要
采用稻田围隔法,研究了中华绒螯蟹放养规格和密度对生长和产量的影响。放养设3个规格:5.0、6.3、8.3 g/只,每一规格设3个密度,即7500、9750、12000只/hm2,每一密度设2个重复。试验结果表明:放养规格和密度对中华绒螯蟹生长和产量均有显著影响。
Effect of initial size and stocking density on growth and yield of Chinese mitten-handed crab, Eriochier sinensis, was studied with land-based enclosures in a rice field. The crab with initial body weight of 8. 3 g,6.3 g and 5.0 g was stocked at a rate of 7500,9750 and 12000 individuals per hm^2 with two replicates for each group. The results showed that effect of size and stocking density of the crab had significant effect on growth rates（SGR）,survival rates,market size and yield.
