North Carolina Sea Grant will fund nine N.C. Fishery Resource Grant Program projects in 2013. FRG supports cooperative research among commercial and recreational fishermen, seafood businesses and scientists in projects that have practical applications for the community.

This program encourages people in fisheries-related industries to explore innovative ideas to protect and improve fisheries, based on their familiarity with and knowledge of the needs of fishing communities. They are partnered with academic researchers to ensure useful, well-documented results.

"This collaborative research program is not only unique to the state, but has truly placed North Carolina as a leader in the nation, through our commitment to ensure the sustainability of strong fishing communities," says Susan White, Sea Grant executive director. "The cost-effective program continues to provide significant benefit to the state, both economically and culturally, as changing environmental conditions and resource management efforts require new approaches to be tested and implemented."

This year, research topics include testing new fishing gear, measuring mercury content in fish and developing new aquaculture techniques.

A fisherman from Sneads Ferry is collaborating with a North Carolina State University researcher to determine the optimal mesh size for the traps used to catch black sea bass. Farther south, a Wilmington shrimper is investigating a device to reduce the amount of bycatch, or unwanted species, in his shrimp trawl. Both teams expect that gear adjustments will reduce labor and trip costs, as well as help them haul in higher-quality catches.

A charter boat captain from Wilmington will join University of North Carolina Wilmington researchers to evaluate the variation in mercury content for wahoo, mahi-mahi and yellowfin tuna based on season and size. Large quantities of the heavy metal can pose health risks to consumers.

The 2013 projects are listed below.
