When was your last gut performance checkup?

The aquaculture industry is enjoying a period of rapid growth and investment due to the high demand for aquatic protein. Production techniques have intensified and innovation in management techniques are constantly being implemented to maximize output; fish are even being farmed in the desert thanks to innovation!

Yet, the aquaculture industry must also stay adaptable to remain naturally ahead. Adopting new technologies alone will not guarantee success. Aquatic species are highly sensitive to a number of external factors that must all be managed throughout the production cycle.
Traditionally, disease management in the aquaculture industry means the administration of antibiotics. However, regulatory guidelines and consumer demand for antibiotic free fish and shrimp products have changed the market. Thanks to the introduction of natural alternatives, feed additives such as organic acids, phytogenics and probiotics can be used in place of antibiotics to reduce disease challenge. We delve into results with organic acids and yeast in the first article on page 4 of this issue of Science & Solutions.
The use of plant-based protein in aqua feeds is a costeffective alternative to fishmeal. Producers should be aware that plant-based protein sources are often contaminated by harmful mycotoxins. The aquaculture industry has relatively little knowledge or experience of dealing with these anti-nutritional factors compared with other terrestrial livestock producers. On page 9, Rui Gonçalves highlights five management tips that the aquaculture sector can employ thanks to experience gathered by the livestock sector.
Finally, as in any industry, measuring and monitoring performance is vital. Constant measurement of performance indicators, such as those presented on page 15, will allow the early identification of problems so that the necessary adjustments can be made to ensure maximum profitability. Do you use any or all of these performance indicators in your business? Regardless of which formula you use, talk to your BIOMIN representative about making improvements to your performance.

We hope you enjoy reading this issue of Science & Solutions, keeping you naturally informed.

Organic Acids and Autolyzed Yeast Reduce the Impact of Pathogens in Fish
Rising demand for aquatic protein is driving the intensification of aquaculture production, which is increasing the incidence of diseases. High stocking densities and high organic outputs provide optimum conditions for the spread of pathogens including a wide range of microorganisms, viruses, parasites and fungi. Organic acids and autolyzed yeast products can reduce the impact of pathogens, supporting performance and profitability.

Mycotoxin Management in Livestock Production: A Model for Aquaculture?
Future growth and sustainability of the aquaculture industry depend on the sector’s ability to identify alternative sources of protein to substitute fishmeal in aquafeeds. Consequently, many new alternatives are available, e.g. insect meal, macroalgae meal or single-cell protein. However, high costs and limited availability are still challenges to overcome. Plant-based meals seem to be one of the most promising and viable solutions, but a common problem is the presence of mycotoxins.
