“…In the present study, taurine levels up to 0.50 g/kg diet increased the LZ and ACP activities, C3, C4 and IgM contents, as well as up‐regulated the mRNA levels of hepcidin, LEAP‐2A, LEAP‐2B, β‐defensin‐1 and MUC2 in the three intestinal segments of young grass carp, implying that taurine supplementation could improve the intestinal immune function of fish. In addition, the immune function of fish is also related to inflammatory response, which is primarily mediated by cytokines (Abdelrazek, Tag, Kilany, Reddy, & Hassan, ; Wang et al, ). Hence, we next systematically investigated the effects of taurine supplementation on cytokines in the intestines of fish.…”

The effects of taurine supplementation on the growth and intestinal immune function in young grass carp (Ctenopharyngodon idella) were investigated in this study. A total of 540 fish (initial average weights of 255.74 ± 0.65 g) were fed one fishmeal diet and five all‐plant protein source‐based diets with graded levels of taurine (0 to 1.98g/kg diet) for 60 days, and then challenged with Aeromonas hydrophila for 14 days. First, the results showed that the taurine supplementation improved growth (PWG, TGC, FI and FE), enteritis resistance, intestinal antimicrobial compounds (LZ, ACP, C3, C4, IgM, hepcidin, LEAP‐2A, LEAP‐2B, β‐defensin‐1 and MUC2) and attenuated intestinal inflammation in young grass carp under the all‐plant protein source‐based diet. Second, the taurine supplementation attenuated intestinal inflammation partially referring to nuclear factor kappa B (NF‐κB) and target of rapamycin (TOR) signallings. Finally, under the all‐plant protein source‐based diet, the comparable level of taurine supplementation based on growth and ability against enteritis relative to fishmeal diet was established as 0.50 g/kg diet, and the optimal levels of taurine supplementation based on thermal‐unit growth coefficient (TGC), ability against enteritis and acid phosphatase (ACP) activity were established as 0.97, 1.08 and 1.21 g/kg diet, respectively.

Microorganisms play an important role in water quality maintenance, waste management, productivity enhancement, nutrient cycling, functional feed development, protection against infectious diseases, delivery of antigens and several other health benefits in aquaculture. The most significant use of microbes in aquaculture to minimize the antibiotics and drugs is through probiotics. The scope of probiotics in modern aquaculture has been enormous due to the detrimental consequences of routinely used antibiotics and chemotherapeutic agents and demand for safe aquatic products for human consumption. Since past few decades, both scientific and commercial interests are burgeoning in this field, and over the years, several probiotics are successfully used in aquaculture. Among various probiotics that are being used, Bacillus species are the common probiotics that are used in different aquatic animals. Several probiotics species belonging to Bacillus genus are currently been used, and Bacillus subtilis is one of such probiotics that is very well‐researched and most widely used probiotics in aquaculture. While its probiotic use has already been an important component in diverse aquaculture practices, its application in water quality improvement, utility in bioflocs/bioremediation and vehicle to express and delivery of heterologous antigen are noteworthy. It exerts innumerable beneficial effects such as improvement of growth, nutrition, immunity and disease resistance in aquatic species. This bacterium adopts a variety of disparate and overlapping mechanisms such as synergistic, antagonistic, competitive exclusion and immune‐stimulating effects. This review summarizes various applications of this bacterium as probiotics, bioremediating agent, bioflocing agent and possible live vaccine vehicle in aquaculture.

“…Yan et al demonstrated that heat-inactivated B. pumilus SE5 could effectively improve growth performance and remarkably upregulated expression of TLR2 and pro-inflammatory cytokines (IL-8 and IL-1β) in head kidney of grouper (Epinephelus coioides) [68]. More recently, Wang et al revealed that heat-inactivated B. clausii DE5 improved feed utilization and the expression of TLR5, pro-inflammatory cytokines (IL-8 and IL-1) and TGF-1 in the head kidney and intestine of grouper [69].…”

China is the largest aquaculture producer in the world. Antibiotics were extensively used to ensure the devel-opment of the intensive aquaculture; however, the use of antibiotics causes safety-and environment-associated problems. As an alternative strategy to antibiotics, aquatic probiotics have attracted attention. The microbial organisms used as probiotics or tested as potential probiotics in Chinese aquaculture belong to various taxo-nomic divisions, including Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria and yeast. Moreover, the mixture of probiotic strains and synbiotics are also widely used. Studies on the mode of action of aquatic pro-biotics have extended our understanding of the probiotic effects, and novel mechanisms have been discovered, such as interference of quorum sensing. However, use of probiotics in Chinese aquaculture is still at an initial stage, and there are potential risks for some probiotic applications in aquaculture. Further regulation and management are required to normalize the production and usage of aquatic probiotics. In this review, we discuss species, effects, and mode of actions of probiotics in Chinese aquaculture since 2008. Challenges and future directions for research are also discussed.
