A new study from the University of Gothenburg suggests that kelp flies (a type of insect) and marine yeast could be used as salmon feed. These two raw materials can be produced using byproducts from the seafood industry, which would otherwise be discarded.
Marine yeasts are ubiquitous in marine environment and they can be found in the ocean, marine sediments, digestive tracts of marine organisms etc. Marine yeasts can tolerate extreme environments like other marine microorganisms.
The fly larvae and marine yeast have over 50 percent high-quality proteins and high levels of beneficial omega-3 fatty acids that fish need to grow and thrive – ultimately, provide healthy food for humans.
