Use of Probiotics in Aquaculture

Aquaculture is the farming of aquatic organisms (especially fish) that has acquired a special position in the global economic and livelihood panorama. The importance of the fishery sector grows days by day as its demand increases for human consumption. Therefore several types of artificial feed are applied for accelerating the growth and increasing the production rate. Nowadays , probiotics (live microorganisms) are used in aquaculture for increasing the disease resistance power and improving the water quality. This review article summarizes the use of different types of probiotics in the aquaculture sector.

Probiotics, which have been widely used in livestock rearing, have recently been applied to aquaculture. Probiotics are defined as live cells or a substrate that provides benefits through stimulation of growth, improved digestion, and improved immune response. Probiotics can also improve water quality. This review summarizes the current understanding of the use of probiotics in aquaculture, including the definition and mechanism of probiotics, and describes their application, and prospects and difficulties associated with their use in aquaculture. This review includes general knowledge of probiotics from previous studies and evaluates the efficacy of probiotics in aquaculture.

The research of probiotics for aquatic animals is increasing with the demand for environmentfriendly aquaculture. The probiotics were defined as live microbial feed supplements that improve health of man and terrestrial livestock. The gastrointestinal microbiota of fish and shellfish are peculiarly dependent on the external environment, due to the water flow passing through the digestive tract. Most bacterial cells are transient in the gut, with continuous intrusion of microbes coming from water and food. Some commercial products are referred to as probiotics, though they were designed to treat the rearing medium, not to supplement the diet. This extension of the probiotic concept is pertinent when the administered microbes survive in the gastrointestinal tract. Otherwise, more general terms are suggested, like biocontrol when the treatment is antagonistic to pathogens, or bioremediation when water quality is improved. However, the first probiotics tested in fish were commercial preparations devised for land animals. Though some effects were observed with such preparations, the survival of these bacteria was uncertain in aquatic environment. Most attempts to propose probiotics have been undertaken by isolating and selecting strains from aquatic environment. These microbes were Vibrionaceae, pseudomonads, lactic acid bacteria, Bacillus spp. and yeasts. Three main characteristics have been searched in microbes as candidates Ž . to improve the health of their host. 1 The antagonism to pathogens was shown in vitro in most Ž . Ž . cases. 2 The colonization potential of some candidate probionts was also studied. 3 Challenge tests confirmed that some strains could increase the resistance to disease of their host. Many other beneficial effects may be expected from probiotics, e.g., competition with pathogens for nutrients or for adhesion sites, and stimulation of the immune system. The most promising prospects are sketched out, but considerable efforts of research will be necessary to develop the applications to aquaculture. q

Probiotics can be used as beneficial alternative to enhance the aquaculture production in sustainable way. Selection of the right strain and dose for particular aquaculture species is necessary for the desirable benefits of probiotics application. Probiotics can be administrated as water additives, feed additives and through injection of which as feed additives is commonly used in aquaculture. Application of probiotics has various benefits in aquaculture production as improve the growth performance, enhances the feed utilization, enhance the immune defense against pathogens, disease resistance, improve water quality and enhance stress tolerance capacity. Thus, application of probiotics in aquaculture can be used at the farm level to enhance the economic performance of the aquaculture species.

Aquaculture is an important aquatic food-producing sector to fulfill nutritional food demand of a continuously growing world population. However, diseases outbreak became a major issue in aquaculture which results in huge economic loss to the aquaculture sector. The use of expensive health care drugs for treatment have negative impacts on the aquaculture species and also on the environment. So there is a growing concern to find other safe, non-antibiotic based and eco-friendly alternative for the improvement of the health and treatment of the various diseases. The use of probiotics is a secure alternative approach for the control the infections, boost the immunity and treatment of diseases. The benefits of probiotics include improvement of improved digestion, stimulation of growth, boosting immune response and recuperate the soil and water quality. Probiotics supplements use via in water, soil and feed in the shrimp and fish farming to fight against various pathogens and improve the overall health as they show antibacterial, antifungal and anti-viral properties use of probiotics in aquaculture has become a recent trend.

With the growing claim for environmentally pleasant aquaculture, the application of non-antibiotic eco-friendly agents such as probiotic which is being considered one most significant tool for health management in the field of aquaculture. Generally, probiotics are live microorganisms , which, when administered in adequate amounts, confer health benefits to the host. These microorganisms are able to colonize and multiply in the intestine of the host and therefore show numerous beneficial effects by modulating various biological systems in the host. Probiotics or their secreted products found to use in aquaculture to control disease, and replace the use of chemotherapeutic agents. A large quantity of beneficial Gram-positive as well as Gram-negative bacteria, microalgae, and yeasts have been evaluated as probiotics in aquaculture. Probiotics application in poultry and swine rearing are well documented, while little has been concentrate to include them into aquaculture. This review pr...

Probiotic is a useful microorganism that directly or indirectly used to protect the host animal against pathogens. The bacterial pathogens are becoming more and more resistant to antimicrobial drugs, pesticides, and disinfectants that are used in aquatic disease control and high growth of production. For this reason, the probiotics study in aquaculture is a rising demand to ensure eco-friendly sustainable aquaculture as an alternative to antibiotics. The advantages of such probiotics enhance feed value, enzymatic stimulation in the digestive system, and reverse habitat for pathogens, influence anti-mutagenic activity, and improved immune response. The research of probiotics in gut microbiota of aquatic animals has not characterized adequately, and their impact on the environment is not widely deliberated. The impact on enzyme activity related to the fish metabolism system should be well-identified by further study. The application and the bio-security of probiotics in fish should be properly evaluated. The farmer should have a brief knowledge about the probiotics organism and should be careful during applying to the culture field.

The Significance of Probiotics in Aquaculture: A Review of Research Trend and Latest Scientific Findings, 2025

Millions of people around the world rely on aquaculture as a major source of food. In the recent few years, probiotics have gained considerable attention as an alternative agent to antibiotics. They have been shown to play an important role in improving aquaculture species through different mechanisms, mainly disease management, improving their growth performance, and improving water quality. Consequently, this review aimed to identify the key areas of research in the global literature about the influence of probiotics on aquaculture based on the selected keywords "aquaculture" AND "probiotics" AND "growth performance" AND "disease resistance" (APGD). The meta-data of the published literature were extracted from the Web of Science (WoS) database on 23 December 2024, and then the co-authors, countries, and keywords were analyzed and visualized using VOSviewer (v. 1.6.20). The search found a remarkable number of documents, which included 175 APGD documents. The results of the bibliometric analysis of the global literature reveal a substantial increase in the publication of APGD documents from 2019 to 2024. Asia, particularly China (32.3% of documents), has emerged as a leader of APGD publications, followed by Iran (8.67%), India (8.01%), Malaysia (7.5%), and Spain (7.5%), respectively. Keyword analysis revealed the prevalence of disease resistance (length = 1793), probiotics (1348), aquaculture (1169), and growth performance (913) as the most impactful keywords based on the WoS database. This could indicate that most of the APGD documents were focused on disease resistance and probiotics relationships. In addition, an extensive review of the recent literature showed that probiotics have demonstrated a remarkable efficacy in improving the growth performance, feed utilization efficiency, disease prevention, and water quality management in various aquaculture species under different aquaculture systems when used as feed or water additives for 30-90 days. It can be concluded that Asia is the lead continent in aquaculture probiotics research, with a significant increase in APGD documents in the last 5 years. Probiotics played a major role in improving aquatic species. This research aims to provide valuable insight into the use of probiotics in aquaculture and highlights the need for further research to fully understand their benefits and mechanisms of action.

Fish a protein, vitamin rich and fat deficient diet is considered as a vital brain food. Aquaculture has emerged to provide nutritional and food security to people. The three Indian major carps, namely, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala) are the major contributor of Indian aquaculture production. The use of probiotics in aquaculture is becoming increasingly popular, microbial cells. Probiotics should be defined as live microbes which, when administered in adequate amounts, confer a health benefit on the host. Thus Probiotics are defined as live cells or substrates that provide benefits by stimulating growth and improving immune response. The review focuses on the use of Probiotics as prophylactic rather than therapeutic. Commercial production of Probiotics requires a consideration of safety issues.
