| 摘 要： | 密度梯度设置为50粒/m2、100粒/m2、200粒/m2、400粒/m2、800粒/m2、0粒/m2的文蛤的养殖密度对养殖体系中底质硫化物和水体COD、溶解氧等因子的影响实验表明:文蛤密度加大,硫化物产生的幅度加大,并与COD呈显著线性关系,溶解氧消耗加剧,水质恶化提前,文蛤密度加大是水质恶化的主要原因之一。实验期间,密度在100粒/m2以上时,文蛤发生规模死亡,密度在100粒/m2以下时,文蛤没有发生死亡,但密度在100粒/m2时,有害物质硫化物的量值在实验后期有上升趋势,表明文蛤生存胁迫加大,密度在50粒/m2时,文蛤生长良好,水质变化不大,适于规模养殖。

| Abstract: | The experiment about hard clam, Meretrix meretrix, density factor was conducted in Oceanographic and FisheriesInstitute of Jiangsu Province. The hard clam stocking densities were fifty, one hundred, two hundred, four hundred, eight hundredand zero in every sq.m, respectively. The results showed that sulfured was increased, the expence of DO was increased, the time ofwater quality deterioration was advanced along with the increase of hard clam stocking density. |
