The sector is exciting and poised for growth, so what's holding back offshore aquaculture projects from profitability?

Langley Gace, senior vice president of business of development at aquaculture equipment and technology supplier Innovasea, told IntraFish while serving as a panelist for its Aquaculture Innovation Summit 2021 that feed-related expenses equal 50 percent or more of an offshore farm's operating costs.

Reducing the feed conversion ratio (FCRe) -- the efficiency with which a fish converts feed volume to size and weight -- for offshore operations can have dramatic impacts on a farm's bottom line, he said.
