SEACOR - Findings, Coos Bay

Click on images to see larger

 

The information we collected enabled us to map the location of clams and features of their surrounding environment. The maps presented on this webpage display where we found clams of each species and at what densities. Overall, the distribution and number of the four clam species we investigated varied by location within the bay. These species also seemed to be associated with certain aspects of their environment.

Areas sampled in Coos Bay by SEACOR

DAM sampling locations

In 2008, SEACOR studied the south part of the Coos bay:

    • Clam Island
    • Pigeon Point
    • South Slough
DAM sample locations

Butter Clams

Butter clams were found in high densities in Coos Bay but were most common at Pigeon Point.

They were often found on high sandy bars, called butter bars, and occurred in areas with little algae.

Cockle Clams

There were considerably fewer cockle clams than butter clams or gaper clams in Coos Bay.

Cockles live near the surface and were found in areas with oxygenated sediment and plentiful algae.

They were most abundant at South Slough and Pigeon Point.

Gaper Clams

Gaper clams were also found in high abundance in Coos Bay.

They were found in low tidal areas with eelgrass (Zostera marina) and were most abundant at Clam Island.

Native Littleneck Clams

Native littleneck clams were found infrequently during our survey of Coos Bay.

They were present at Pigeon Point and South Slough in low tide areas with eelgrass and oxygenated sediments.
