Commercial Fish Landings
Long Beach-Barnegat and Point Pleasant ports are 32nd and 36th most valuable commercial fishing ports in U.S. (NMFS and NOEP 2010)
Combined ports would be the 16th most valuable commercial fishing port in the U.S. with $48.6 million in annual fish landings.
Blue crab landings in the Barnegat Bay •23.5% of total New Jersey blue crab landings. •In 2007, 4.8 million pounds of blue crabs were harvested in NJ •Landed value of $5.5 million •Estimated value of the bay’s blue crab fishery is about $825,000.
Summer Flounder
Summer flounder (42% of trips), striped bass (19% of trips), and bluefish (7.5% of trips), Ligget in Bricker et al. (2007)
$10.26 benefit to increased catch per trip (McConnell and Strand (1994).
Summer flounder accounts 2.5 million trips or about 42% of 5.9 million inland fishing trips in the Barnegat Bay.
benefit to summer flounder fishermen from improved in water quality in Barnegat Bay is $25.4 million/year.
