Farming kelp to sell as food, beauty products, fertilizer additives and other goods is a growing industry in Maine, but also a costly one. One key barrier for new farmers is a lack of cost-analysis tools to help reduce expenditures and develop sustainable business plans.
Farming kelp to sell as food, beauty products, fertilizer additives and other goods is a growing industry in Maine, but also a costly one. One key barrier for new farmers is a lack of cost-analysis tools to help reduce expenditures and develop sustainable business plans.
Researchers from Kelson Marine in Portland, Maine and the University of Maine developed a new tool that provides detailed economic analyses for kelp farmers and reveals strategies for reducing the cost of farmed seaweed. It accounts for differences in site selection, weather, crop size and dozens of other scenario-specific factors. It can be used for operations nearshore and offshore, like large-scale farms in the Gulf of Maine that are fully exposed to nor-easter driven waves.
“By using this tool to investigate the comprehensive implications of any given farm design or operational decision, we can help kelp farmers meaningfully reduce production costs and achieve economic sustainability,” said project lead Zach Moscicki, ocean engineer with Kelson Marine. “The tool allows us to carefully navigate the multitude of tradeoffs associated with any such decision and avoid leaning into overly narrow-scoped improvements that may reduce costs in one way, but increase costs or reduce production via some other indirect but connected pathway.”
