Conclusions of the studies are as follows : 1 Water temperature, water quality and dissolved oxygen ( DO ) were the important factors in incubation and culture of American shad. 1水温、水质、溶氧等是影响美洲鲥人工孵化和养殖的重要因子。
Water Quality Monitoring Sampling and Dissolved Oxygen Determination in Large Reservoir 大型水库水质监测采样和溶解氧的测定
The result showed : ( 1 ) poor water quality and lack of dissolved oxygen would produce a thick sulfides layer at the bottom of the old pond where organic pollution is also more serious; 结果表明:1.仅在水质严重恶化时,在有机物污染程度高的旧池底层水中产生一硫化物薄层;
Future aquiculture aims at high survival rate and high quality, and the precondition for all this is keeping the stability of water quality. The water quality parameters such as temperature, dissolved oxygen, pH, and turbidity should be received in time. 未来的水产养殖以高成活率和高质量为目的,实现这些目的的前提条件是保持养殖水质的稳定性,如水温、溶解氧、pH值和浊度等水质参数都需要及时获取。
According to experts ' advice, the most important indicators for water quality of crab ponds were determined : dissolved oxygen, pH, temperature and salinity. 通过专家咨询的方式,确定了针对河蟹池塘养殖的最主要水质指标:溶解氧、酸碱度(pH值)、温度和盐度。
