对对虾养殖池塘溶解氧含量及其收支情况的研究结果表明，虾池dO值具有明显的季节和昼夜变化。浮游植物光合作用是虾池溶解氧补充的主要来源，夏季最高可超过5Mg/（dM3·d）。养殖后期对虾的耗氧量占总耗氧量的34%，底质和池水耗氧量分别占30%和35%。根据虾池氧的收支情况讨论了池养对虾的生产容量。The dissoived oxygen content and budget in shirmp ponds were surveycd.The resultsshowed that signiFicant seasonal and diel variation of DO values were Found and most DOvalues were higher than 4.0mg/dm3.The main source of DO was the photosyntheticproduction.The DO supplement may be more than 5.0mg/(dm3·d) in summer.The oxygenuptaken by shrimps al the Final perlod of culture was only 34% of total oxygen depletion ofpond, while pond waler and sedlment occupied 35 % and 30% respectively.The reasonableproduction capacity of shrimp pond is discussed according to the DO budgel of shrimp pondsunder current conditions.国家自然科学基
