Benefits of Probiotics Aquaculture for Fish

By Bryan Low

Probiotics have long been used to stabilize the internal environments of animals, from cattle to fish. Probiotics are essential in aquaculture since they help improve the overall health status of marine stock which in turn helps ensure higher yields and higher profits. Since fish get their nutrients from the water, probiotics are naturally administered as additives in the water. As a biological alternative to antimicrobial compounds that are currently being used to prevent bacterial infection in aquaculture, probiotics offer a safer, natural option for fish farmers who prefer a more natural way of raising fish stock.

How Aquaculture Probiotics for Fish Work
Aquaculture probiotics are basically just beneficial bacteria that when consumed, occupy the space that would otherwise be occupied by harmful bacteria. This results to a reduced incidence of disease and infection in aquaculture, higher yields and more returns on the investment. The good bacteria protect fish stocks from the harmful action of bad bacteria through competitive exclusion which means that they prevent the increase in population of bad bacteria by increasing their own population. Common types of probiotics being used in aquaculture include lactic acid bacteria which is commonly used as aquafeed. Another probiotic that is studied for its probiotic properties is E. faecium. It has probiotic properties that can be used alone or in combination with other beneficial intestinal bacteria.

Aside from being a natural option to antibiotics, probiotics have been scientifically shown to reduce fish mortality, fish deformities, reduce the incidence of fish deformities and conditions like the Vertebral compression syndrome which is common in salmonids. This condition often leads to reduced fish welfare and higher mortality in conventional aquaculture industries.

Choosing the Right Probiotic Strain for Aquaculture
The right probiotic strain will differ according to the water quality and the species of fish being cultured. One species may react differently to a type of bacteria and not all kinds of probiotics will produce beneficial effects for every species of fish. It is important to look at the normal range of temperatures, salinity, ability of the bacteria to thrive in specific conditions and its ability to colonize the gut of the marine animals when looking for the right probiotic strain. Fish farmers must also take into account the safety of the strain and ensure that no transmission of antibiotic resistance takes place.

Proper Fish Management with Probiotics
Probiotics are relatively new in fish farming, since live bacteria have long been used for their beneficial purposes in cattle and other land animals. Aquaculture experts say that probiotic use must be controlled in fish farming for maximum efficacy. This means knowing the right feed formulation, ensuring that the marine environment is clean and safe for fish stocks and that general disease prevention mechanisms are in place.

Companies like Syndelasia.com offer a number of products formulated to promote and maintain high water quality and optimum health for fish stock in aquaculture and other fish based industries. Promotion of optimum fish health through modern and trusted techniques for disease diagnosis, biosecurity, food safety and technology will help improve the status of Malaysian aquaculture to make it suitable and competitive for a global market.
