| Notes | In 1977, sport clam digging regulations were changed to reduce the bag limit of bay clams from 36/person to 20/person, and a limit of 36 softshell clams. This was done to protect clam stocks. Commercial fishers had to report bay clams landed for fish bait starting in 1983. Before 1976, Alsea Bay was the major harvest area for ghost (sand) shrimp for the baitfish industry. After 1975, Tillamook Bay began producing more commercially harvested ghost shrimp. The 1982-83 El Nino caused significant erosion on the coast, and raised tide levels, which reduced recrational bay clamming. |
