PORTLAND— A new report shows that Maine’s seafood harvest last year was the third most valuable among the states, thanks to lobster.

An annual report released Wednesday by the National Oceanic and Atmospheric Administration shows that Alaska’s seafood harvest was the nation’s tops by far in terms of value, followed by Massachusetts and Maine. Maine’s catch was worth $448 million, with lobster accounting for a majority of the value.

The report says Stonington was the No. 1 Maine port for the value of the seafood landed there, at $46 million. Virtually all of Stonington’s catch is lobsters.

Portland was the No. 2 port in terms of value, but was tops in Maine for volume of the catch.
