The Aquaculture Podcast Show • by Wisenetix

In this episode of The Aquaculture Podcast Show, we explore how dietary macronutrients influence tilapia gut microbiota, intestinal health, and feed efficiency. Discover how alternative proteins, oxidized lipids, and carbohydrates affect beneficial microorganisms, disease resistance, and antibiotic interactions. Learn why precision feed formulation must consider intestinal health alongside growth performance to support sustainable tilapia production. Listen now on all major platforms!

In this episode of The Aquaculture Podcast Show's Chile Special Series, we examine nutrient management in intensive finfish production under changing coastal conditions. We explore how reduced flushing can increase nitrogen accumulation and why integrating macroalgae and bivalves may strengthen carrying capacity management. By combining biological extraction with dynamic production models, farms can improve long-term stability in restricted coastal environments. Listen now on all major platforms!

In this episode of The Aquaculture Podcast Show, Dr. Kevin Fitzsimmons, from the University of Arizona, explains why rising fishmeal and fish oil costs are accelerating interest in alternative aquafeed ingredients. He discusses algae oils, insect meals, single-cell proteins, animal byproducts, scaling challenges, and commercial adoption while highlighting their importance for sustainable aquaculture nutrition. Listen now on all major platforms! "We see that using these alternative ingredients to replace fishmeal and fish oil is maybe the first big, important step in sustainability." Liked this one?

In this episode of The Aquaculture Podcast Show, we examine how saturated fats and cholesterol influence Atlantic salmon growth, feed efficiency, fillet structure, and pigmentation. As alternative oils become more common, formulations may overlook nutrients essential for metabolic efficiency and product quality. Understanding these interactions can help nutritionists balance scalable ingredients with reliable production outcomes. Listen now on all major platforms!
