Who the heck puts these species lists together for these locations??? Some are wildly inaccurate. I'll attempt cleaning it up a bit from my own knowledge, but I'll undoubtedly make some mistakes/assumptions. I'll start with removing Pollock and Haddock from the list...!
Hamburg Cove is actually a part of the Eight Mile River which flows southward eight miles downstream through the Cove and into the Connecticut River. Hamburg Cove is really two coves, the Inner Cove where Cove Landing is located, and the Outer Cove where one of the most charming and protected anchorages in all of New England welcomes mariners from far and near. The entrance to Hamburg Outer Cove is about seven and a half miles above the Saybrook breakwater off Long Island Sound. US Coast Guard makers located directly across from Brockway Island about one mile past Essex Village clearly identify the beginning of the channel into the Outer Cove. Mariners should consult local charts for markers into the Inner Cove, and visitors are advised to pick up the green rental buoys. Located midway between Boston and New York, and just one hour south of Hartford, Connecticut. Before North Cove in Old Saybrook was dredged for an anchorage, Essex, ("The Best Small Town in America") was the first upriver shelter. It's still a popular boating town with much to see. But just a little farther upriver, as you pass Brockway Island, there's a small opening on the eastern bank. We squeezed through the tree-lined passage, which suddenly widened into a totally protected bowl called Hamburg Cove. It was peace and quiet personified. Hamburg Cove is a freshwater tidal marsh which is an important foraging and resting site for diving ducks such as the bufflehead. There is a family of swans at entrance to the cove. A bald eagle winter roost and several rare plant species occur here too.
