in
Nehalein Bay (Figure 1) during three sampling periods, Nay 17-18, July
19-21, and August 8-10, 1966.
Data from Yaquina and Wotarts bays are in-
eluded for comparative purposes.
Methods
Crab pots, baited with fish carcasses, were placed in the Nehalem
estuary from Crab Rock, near the mouth, to Brighton, approximately one
mile upstream.
The pots were checked twice daily. AU medium and large
crabs captured were measured, checked for shell hardness, and released.
The crab pots were allowed to fish through two incoming tides during each
of the sampling periods0
Crab pots and rings were fished simultaneously on August 10 to obtain
comparative catch data :ror the two types of trapping equipTient.
On August 10, l966
seven crab pots were fished in Netarts Bay, 13
miles south of Nehalem Bay.
These
.ots were allowed to fish only four
hours while the tide was flooding.
