Researchers evaluate different levels of stickwater, a byproduct of insect meal processing
Researchers at Norway-based Nofima say that recent aquaculture feeding trials show that insect meal and even byproducts from black soldier fly (BSF, Hermetia illucens) processing can help fish grow well.
Seeking to measure the effects on salmon parr, which are young, freshwater salmon, the researchers worked with France-based insect producer Innovafeed to feed during the larval stage. At Nofima’s Sunndalsøra research station, they measured differences in digestion and growth when using feeds with 10 percent insect meal and various levels of stickwater, a byproduct of insect meal production thought to be rich in bioactive components. BSF larvae are processed into meal and stickwater.
