Aquaculture feeding – problematic, but not without alternatives

Summary

Animal production is a major contributor to climate change and greenhouse gas emissions, mainly due to the feed production and global trade. Aquaculture is no exception when considering the species which are “fed”, i.e. species depending to a large degree on feed supplied by the operators. Our author describes current feeding practices in aquaculture and the problems they involve and gives an account of progress in research on alternative protein sources.
