Long Island Sound Fun Fact

Long Island Sound is 113 miles long, 21 miles wide (at its widest) and holds about 18 trillion gallons of water. Its average depth is 63 feet – which is just a little deeper than the height of our IMAX screen! Can you fathom that?!

Common Name: Bluefish

Latin Name: Pomatomus saltatrix

Size/weight: Rarely seen larger than 20 pounds and 40 inches long.

Range: Western Atlantic populations range from Canada in the north to Florida and the Gulf of Mexico in the south (depending on season).

Habitat:  Adults inhabit coastal waters and are, at times, found in estuaries, harbors and off sandy beaches.

Diet: The bluefish’s diet includes squid, crabs, butterfish, menhaden, shad, herring, hake and smaller bluefish.  Bluefish are known as very aggressive fish and will often leave partially eaten or maimed prey behind.

Predators:  Sharks, tuna, striped bass, swordfish and humans.

Description:  Actually more green than blue, bluefish have strong, streamlined bodies and sharp, conical teeth.

Conservation Note:  Many fisheries managers believe that bluefish are being over-fished; populations may be on the brink of decline. However, Seafood Watch still lists bluefish as a Good Alternative, but consumers should limit consumption due to concerns about mercury or other contaminants.
