3种水质调控方式对参池底泥异养菌和弧菌数量的比较

为探究不同水质调控方式对海参养殖池塘（以下简称参池）底泥异养菌和弧菌数量的影响,该研究选择了三3类参池,分别是自然纳潮管理方式下的海参养殖池塘（以下简称自然池塘）,配备微孔曝气增氧机的海参养殖池塘（以下简称微孔曝气池塘）和配备养水机设备的海参养殖池塘（以下简称养水机池塘）,对参池底泥中异养菌和弧菌数量的周年变化进行检测。结果表明,各参池中底泥异养菌数量分别为：自然池塘94400~377625 cfu/g,微孔曝气池塘62633~247309 cfu/g,养水机池塘115037~273071 cfu/g,其中自然池塘1月最高,3月最低;微孔曝气池塘5月最高,6月最低;养水机池塘4月最高,8月最低。各参池中底泥弧菌数量分别为自然池塘0~3291 cfu/g,微孔曝气池塘35~5412 cfu/g,养水机池塘0~3037 cfu/g,各参池均呈“春季高,冬季低”的变化特征。弧菌与异养菌数比值在4、5月份相对较高,在2月份较低。通过实验初步比较不同水质调控方式对参池底质微生物数量的影响,为改善参池底质及探究微生物的变化提供理论依据。3种水质调控方式对参池底泥异养菌和弧菌数量的比较

Comparison of three water quality control methods on heterotrophic bacteria and vibrio in the sediment of sea cucumber farming pond

In order to explore the influence of different water quality control methods on the number of heterotrophic bacteria and vibrio in the bottom mud of sea cucumber farming ponds, the study selected three types of sea cucumber farming ponds, namely sea cucumber farming ponds under natural tide management (hereinafter referred to as natural ponds) , sea cucumber farming ponds equipped with microporous aeration aerators (hereinafter referred to as microporous aeration ponds) and sea cucumber farming ponds equipped with water quality regulator ponds (hereinafter referred to as water quality regulator ponds). The annual changes in the number of heterotrophic bacteria and vibrio in the bottom mud of sea cucumber farming ponds were detected. The results showed that the number of heterotrophic bacteria in the bottom mud of sea cucumber cultivation ponds was 94400~377625 cfu/g in natural ponds, 62633~247309 cfu/g in microporous aeration ponds, and 115037~273071 cfu/g in water quality regulator ponds, of which natural ponds are highest in January and lowest in March; microporous aerated ponds are highest in May and lowest in June; water quality regulator ponds are highest in April and lowest in August. The number of Vibrio in the bottom mud in the sea cucumber culture ponds was 0~3291 cfu/g in natural ponds, 35~5412 cfu/g in microporous aeration ponds, and 0~3037 cfu/g in water quality regulator ponds. All sea cucumber farming ponds showed the characteristics of "highest in spring and the lowest in winter". The ratio of vibrio to heterotrophic bacteria was relatively higher in April and May, and lower in February. Preliminary experiments are conducted to compare the effects of different water quality control methods on the number of microorganisms in the bottom of sea cucumber farming ponds, and provide a theoretical basis for improving the bottom quality of sea cucumber farming ponds and exploring microbial changes.
