Op-ed: IFFO is wrong on alternative feeds

By Kevin Fitzsimmons, Seafood Source:

“In response to the Sept. 23 SeafoodSource article, “IFFO’s Johannessen: Use of marine ingredients in aquafeed ‘will not decline in the foreseeable future,’” we would like to provide an alternative perspective on the future of marine resources in aquafeed.

The reality is, there is not enough wild-caught fish to feed the world. According to a World Bank study, as of a decade ago, the ocean could not keep pace with demand, and fish catches are declining.

Complete replacement of fish oil and fish meal in the diet of juvenile California yellowtail…

By Kevin R. Stuart, Frederic T. Barrows, Constance Silbernagel, Kelly Alfrey, David Rotstein, and Mark A. Drawbridge:

“California yellowtail (CYT) Seriola dorsalis is a top candidate for aquaculture in southern California. CYT is fed commercial diets whose nutrient profile and ingredient composition rely heavily on fish meal and fish oil. We evaluated the complete replacement of fish oil and fish meal with a Schizochytrium‐derived algal oil as an essential fatty acid source and poultry by‐product meal and spirulina as primary protein sources, in the diet of juvenile CYT (average initial weight—19.95 ± 0.09 g).”

Removing Fish From Fish Diet for Tastier, More Sustainable Aquaculture

By NOAA FIsheries:

“In a groundbreaking study, researchers have successfully raised a carnivorous fish on a diet free of fishmeal and fish oil without any harmful effects. The kampachi (Hawaiian yellowtail, almaco jack) were raised on a diet of feed-grade poultry meal and a fish-free oil blend high in omega-3 fatty acids. They were not only as healthy as those grown on traditional feed but also more flavorful in blind taste tests.”

The future of food from the sea

By Costello, C., Cao, L., Gelcich, S. et al.:

“Global food demand is rising, and serious questions remain about whether supply can increase sustainably. Land-based expansion is possible but may exacerbate climate change and biodiversity loss, and compromise the delivery of other ecosystem services 2, 3, 4, 5, 6. As food from the sea represents only 17% of the current production of edible meat, we ask how much food we can expect the ocean to sustainably produce by 2050.”
