Habitats Located at Fish Harbor:
Located in the basin of the inner harbor, habitats in Fish Harbor include muddy seafloor, pilings, riprap, and pelagic habitat.

Seafloor
The seafloor in basins is comprised of mostly muddy sediments with some small patches of eelgrass on shallow slopes near the shoreline. Common animals here include gobies, shrimp, lobsters, and animals that burrow into the sediments such as worms and small clams.

Pilings
Piling habitat in the inner harbor is widespread due to the many marinas and marine terminals. Communities on pilings vary with tidal zone, with barnacles and oysters common in the upper intertidal, while macroalgae, mussels, scallops, and sponges are more common in the lower intertidal and subtidal.

Fish Harbor is an enclosed basin uniquely located near the outer harbor, and the entrance to Fish Harbor has kelp and eelgrass habitat along the shorelines. Further inside the basin, the habitats look more similar to inner harbor areas with silty, muddy seafloor habitats and communities anchored on the pilings lining the shoreline. This mix of habitats makes Fish Harbor communities diverse and abundant, with fish, invertebrates, marine mammals, and birds all common throughout. Select the images below to learn about Fish Harbor.
