Abstract
Studies have shown that ancient cultures used microalgae as food for centuries. Currently, scientific reports highlight the value of nutritional composition of microalgae and their ability to accumulate polyunsaturated fatty acids at certain operational conditions. These characteristics are gaining increasing interest for the aquaculture industry which is searching for cost-effective replacements for fish meal and oil because these commodities are one of the most significant operational expenses and their dependency has become a bottleneck for their sustainable development of the aquaculture industry. This review is aimed at highlighting the use of microalgae as polyunsaturated fatty acid source in aquaculture feed formulations, despite their scarce production at industrial scale. Moreover, this document includes several approaches to improve microalgae production and to increase the content of polyunsaturated fatty acids with emphasis in the accumulation of DHA, EPA, and ARA. Furthermore, the document compiles several studies which prove microalgae-based aquafeeds for marine and freshwater species. Finally, the study explores the aspects that intervene in production kinetics and improvement strategies with possibilities for upscaling and facing main challenges of using microalgae in the commercial production of aquafeeds.
期刊介绍:
Aquaculture Nutrition is published on a bimonthly basis, providing a global perspective on the nutrition of all cultivated aquatic animals. Topics range from extensive aquaculture to laboratory studies of nutritional biochemistry and physiology. The Journal specifically seeks to improve our understanding of the nutrition of aquacultured species through the provision of an international forum for the presentation of reviews and original research papers.
Aquaculture Nutrition publishes papers which strive to:
increase basic knowledge of the nutrition of aquacultured species and elevate the standards of published aquaculture nutrition research.
improve understanding of the relationships between nutrition and the environmental impact of aquaculture.
increase understanding of the relationships between nutrition and processing, product quality, and the consumer.
help aquaculturalists improve their management and understanding of the complex discipline of nutrition.
help the aquaculture feed industry by providing a focus for relevant information, techniques, tools and concepts.
