摘要:

在凡纳对虾养殖中,添加牡蛎壳能改善养殖水质和凡纳对虾生长状况。但牡蛎壳原位水质处理对水质和凡纳对虾生长的影响,以及牡蛎壳生物膜微生物群落组成及其动态演替仍缺乏系统的研究。为探究添加牡蛎壳对凡纳对虾生长性能和养殖水质的影响,本研究通过设置对照组、牡蛎壳低添加量组(体积分数1‰)、牡蛎壳中添加量组(体积分数2‰)、牡蛎壳高添加量组(体积分数4‰),比较不同添加量的牡蛎壳对凡纳对虾生长指标的影响,分析牡蛎壳表面细菌群落分布特征。结果显示,添加牡蛎壳能显著提高凡纳对虾的存活率(F=9.222,P=0.006)、体长(F=13.267,P=0.002)和体重(F=8.102,P=0.008),低添加量组的存活率(90.73%)显著低于中添加量组(97.50%)和高添加量组(99.17%)。添加牡蛎壳还能提高养殖水中磷酸盐含量(F=52.509,P<0.001),降低亚硝酸盐含量(F=7.323,P=0.011),提高硝酸盐含量(F=23.615,P<0.001)。在牡蛎壳表面生物膜中,黏着杆菌属(Tenacibaculum)随着养殖进程推进相对丰度显著下降,硝化螺旋菌属(Nitrospira)和鲁杰氏菌属(Ruegeria)随着养殖进程推进,相对丰度显著升高。生物膜中硝化螺旋菌属相对丰度的升高,加速了养殖体系中氮循环从亚硝酸盐到硝酸盐的变化,从而改善水质,提高凡纳对虾存活率、体长和体重。本研究对凡纳对虾养殖中的牡蛎壳添加具有指导意义,且为探究牡蛎壳生物膜对水质改善和凡纳对虾健康的促进机理提供了理论基础。

Abstract:

In the cultivation of Penaeus vannamei, the addition of oyster shells can improve water quality and enhance shrimp growth. However, the effects of in situ water quality treatment by oyster shells on water quality and shrimp growth, as well as the composition and dynamic succession of microbial communities in oyster shell biofilms, remain inadequately studied. To investigate the effects of adding oyster shells on the growth performance of Penaeus vannamei and aquaculture water quality, this study established a control group and three experimental groups with low (volume fraction 1‰), medium (volume fraction 2‰), and high (volume fraction 4‰) oyster shell additions, comparing their impacts on the growth metrics of Penaeus vannamei and analyzing the distribution characteristics of bacterial communities on the surface of the oyster shells. Results showed that the addition of oyster shells significantly increased the shrimp survival rate (F=9.222, P=0.006), body length (F=13.267, P=0.002), and body weight (F=8.102, P=0.008), the survival rate of the low addition group (90.73%) was significantly lower than that of the medium addition group (97.50%) and the high addition group (99.17%). The addition of oyster shells also increased phosphate content (F=52.509, P<0.001), decreased nitrite content (F=7.323, P=0.011), and increased nitrate content (F=23.615, P <0.001). In the biofilm, the relative abundance of Tenacibaculum significantly decreased as the aquaculture process progressed, while the relative abundance of Nitrospira and Ruegeria significantly increased. The increased relative abundance of Nitrospira in the biofilm accelerated the nitrogen cycle from nitrite to nitrate in the aquaculture system, thereby improving water quality and enhancing shrimp survival rate, body length and body weight. This study provided guidance on the addition of oyster shells in shrimp cultivation and offered a theoretical basis for further exploration of the mechanisms by which oyster shell biofilms improve water quality and promote shrimp health.
