Resumen
Descripción
Aquafeeds are the largest variable cost in fed aquaculture, accounting for up to 70 percent of total expenses. Their high cost can make fish farming unfeasible, which highlights the need for technological solutions.Improved knowledge of nutrition and the development of extruded feeds have contributed to driving the recent growth in production in the aquaculture sector. However, a gap exists between producers that have access to formulated commercial feed and those that lack it. There is a need to develop or adopt new local ingredients and production systems that allow the viability of small-scale aquaculture with limited resources. The Food and Agriculture Organisation of the United Nations (FAO) provides guidance on how to adopt sustainable practices in aquaculture focusing, among other issues, on choosing more sustainable ingredients for aqua feed. There are highlighted in the Guidelines for Sustainable Aquaculture.FAO has used its expertise to train people to use waste fish in Barbados to make silage that can be used in fish feed, has supposed farmers in formulating and manufacturing feed in Kyrgyzstan, and has trialled feed based on black soldier fly larvae in Nigeria.
