Description

Abstract: Tillamook Bay is an important recreational and commercial clamming area in Oregon. The Oregon Department of Fish and Wildlife (ODFW) has surveyed the subtidal habitat and clam populations there for over four decades starting in 1974. The most recent survey in 2012 was conducted by the Shellfish and Estuarine Assessment of Coastal Oregon project (SEACOR) on target bay clam species: cockles (Clinocardium nuttallii), gaper clams (Tresus capax), butter clams (Saxidomus gigantea), and native littleneck clams (Leukoma staminea). This long temporal dataset provides a unique opportunity to study the trends in clam density (# clams/m2), biomass (grams/m2), and associated habitats. Here, we evaluate subtidal bay clam populations over time, the clam-habitat associations, and summarize regulation changes based on these findings.
