Title : Review of recent advances in replacing fish-based protein and oil with plant-based alternatives in aquafeeds
Abstract:
The growing demand for sustainable aquafeeds has accelerated research into replacing fishmeal and fish oil with plant-based alternatives. Traditionally sourced from wild fisheries, these marine-derived ingredients raise ecological and economic concerns. In response, plant-based ingredients such as soy, canola, and algaederived products have emerged as viable, scalable options.
This presentation reviews recent advancements in the use of plant-based proteins and oils in aquafeeds, focusing on improved digestibility, nutrient bioavailability, and palatability. It also addresses key challenges, including anti-nutritional factors and essential fatty acid deficiencies—and highlights innovative solutions such as novel processing technologies, biotechnological improvements, and refined feed formulation strategies.
The review further explores the economic and environmental impacts of plant-based feeds, regulatory considerations, and industry adoption trends. Drawing on current research, it demonstrates that continued innovation can enable plant-based diets to effectively support fish health, growth, and sustainable production. Soy product inclusion in feeds is featured as a case study to illustrate cost-effectiveness and applicability across diverse aquaculture species.
