Three UNH research projects aim to improve sustainability of the region’s fishing and aquaculture industries and bring better seafood to the table, thanks to funding from the National Oceanic and Atmospheric Administration’s Saltonstall-Kennedy grant program.

With a grant of $297,720, research associate professor of marine biology and aquaculture Extension specialist will lead research to develop a broodstock program for lumpfish, a species native to the Gulf of Maine. Lumpfish are “cleaner fish;” when integrated into salmon and steelhead trout farms, they delouse the farmed fish. While U.S. salmon farmers would like to use lumpfish, much like north Atlantic salmon farms outside the U.S. do already, neither a domestic lumpfish source nor established permitting exist.

Fairchild and Chambers, along with aquaculture program manager Arron Jones and Heather Hamlin of the University of Maine, will study lumpfish as a broodstock and conduct outreach with stakeholders on using them in aquaculture.

体育365Fairchild also received funding ($296,886) for a second project that will improve the sustainability of the lucrative channeled whelk fishery in the northeast. These large sea snails with their iconic “hear the ocean” shells are caught in traps, much like lobsters, with a bait blend that has traditionally included horseshoe crab, an exploited species in jeopardy.

“We propose to work with the whelk industry to develop more sustainable and environmentally-friendly products: traps that allow the escape of whelks that do not meet the minimum legal size, and an effective bait that utilizes less horseshoe crab and more low-cost, low-impact ingredients such as invasive green crabs,” says Fairchild.

A third project, led by Jason Goldstein ‘12G of the in Maine, aims to jump-start an economically viable green crab fishery by better understanding when the invasive crabs are about to molt. UNH fisheries Extension specialist and assistant professor of biological sciences are also participating in the research.

体育365Highly invasive, green crabs pose significant concerns to established fisheries as well as ecosystems. Bradt and others have championed an “eat the invaders” approach by partnering with local chefs, but not knowing when and where green crabs molt (and become soft-shelled) hinders the potential success of a green crab fishery. Furey’s lab will contribute telemetry expertise to track the seasonal movements of green crabs along the coast.
