Abstract

Microbial communities, mainly those with probiotic characteristics, positively affect the culture of diverse organisms, including shrimp. In this study, three diets containing different types of probiotics were evaluated on the composition and diversity of the microbial community in the water column and gut of Litopenaeus vannamei, as well as on the expression of genes related to the immune system and resistance of the organisms after being challenged with WSSV and Vibrio parahaemolyticus. Results showed that probiotics affected the microbial community structure in water and shrimp. The expression of beta-glucan binding protein and prophenoloxidase increased in the treatments with probiotics compared to the control before and after the challenge. Overall the survival of shrimp was higher in all the treatments than in control. Results suggest that using probiotics in BFT systems could provide an extra benefit for these kinds of systems.

不同益生菌饲料对BFT系统养殖凡纳滨对虾肠道微生物特性及基因表达的影响

微生物群落，主要是具有益生菌特征的微生物群落，对包括虾在内的多种生物的培养有积极的影响。本研究通过对3种含不同类型益生菌的饲料进行研究，研究了凡纳滨对虾(Litopenaeus vannamei)受WSSV和副溶血性弧菌攻击后水柱和肠道微生物群落的组成和多样性，以及免疫系统相关基因的表达和机体的耐药性。结果表明，益生菌对水体和对虾的微生物群落结构有影响。益生菌处理前后β -葡聚糖结合蛋白和酚氧化酶原的表达均高于对照。总体而言，各处理对虾的成活率均高于对照组。结果表明，在BFT系统中使用益生菌可以为这些系统提供额外的好处。

期刊介绍： Turkish Journal of Fisheries and Aquatic Sciences" (TrJFAS) is a refereed academic journal has been published by Central Fisheries Research Institute of Turkey and Japan International Cooperation Agency (JICA), and published in English. It aims to address research and needs of all working and studying within the many varied areas of fisheries and aquatic sciences. The Journal publishes English language original research papers, critical review articles, short communications and technical notes on applied or scientific research relevant to freshwater, brackish and marine environments. TrJFAS was published biannually (April & November) between 2001 and 2009. A great number of manuscripts have been submitted to the journal for review from acceptance of the SCI index. Thereby, the journal has been published quarterly (March, June, September and December) from 2010 to 2017. The journal will be published monthly in 2018.
