Long Island Sound - West Chart

Long Island Sound - East Chart

Long Island Sound averages 60 ft in depth, with the greatest depth of over 300 ft at the eastern end. Tidal effects are strongest at the narrow western end, where all the inrushing water flow piles up and makes tidal variations of up to 7 ft. Strong tidal currents are also prevalent, and visibility tends to be poorer than the open ocean, especially at depth.

Sand Lance

Ammodytes americanus

Size: to 8"

Habitat: inshore waters, from surface to bottom

Notes: The Sand Lance is an important link in the marine food chain. It is a major part of the diet of many commercially important fishes, as well as whales and seals. Sand Lances form huge schools to feed on phytoplankton and have the ability to dive into the bottom sediments to escape predators. I have never seen a live one, but they are common in the bellies of other fishes that you may catch.
