The role of aquafeeds in abalone nutrition and health: A comprehensive review

Overpopulation and the pressure on land-based resources have driven the aquaculture sector to increase its production since the 1980s. To address such demands, new aquafeed technologies have been developed relying on natural and artificial ingredients that are commercially viable. In addition, current global sustainable initiatives require feed technologies to reduce the pressure on limited wild fisheries and minimize negative environmental effects. Although there are numerous studies on abalone nutrition, most tend to focus on animal growth and nutrient utilization. A more holistic research approach to ensure a sustainable future for this industry will require the development of feeds that provide integrated nutrition and health benefits. In this review, we aim to synthesize the most recent scientific literature on the nutritional and health benefits and shortcomings of two main abalone feeding approaches (seaweed and formulated feeds) within aquaculture production practices. We also identify major research gaps and future directions for the development of sustainable abalone feeds.

Automated summary

Due to overpopulation and pressure on land resources, aquaculture production has been increased. New aquafeed technologies have been developed to meet the demand, aiming to reduce pressure on wild fisheries and minimize environmental effects. Previous studies mainly focused on abalone growth and nutrient utilization, while more holistic research is needed to develop feeds with integrated nutrition and health benefits.
