Fish Commission of Oregon personnel seined selected locations of Tillamook Bay, Oregon, from June to September 1972, to determine if juvenile salmon were rearing in the estuary and to get some concept of relative numbers of fish in the various parts of the bay. These data then could be compared...
Tillamook Bay chum salmon are caught commercially by gill-nets, both set and drift, and from 1928 through 1949 the landings have averaged 819,689 pounds per season. More chum salmon are caught on Tillamook Bay than on the rest of the Oregon coastal rivers combined. These fish enter the ocean only...
Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...
Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true...
Estuarine residence and growth of juvenile chum salmon
(Oncorhynchus keta) from Netarts Bay, Oregon were estimated
from daily-formed growth increments of sagittal otoliths
which are distinguishable from accretion patterns formed
during freshwater residence. Estuarine residence time was
inversely related to the average size at which juvenile chum
salmon entered Netarts...
This report covers a range of information about shellfish, including the populations of clams in Yaquina & Tillamook bays, the Pacific Oyster mortality event in Coos bay (with a hand-drawn map of Coos Bay), testing of different crab baits, and different statistics about the Coquille River Crab Fishery. This report...
A student report for a Civil Engineering 572 class, this document is an extensive description of the Salmon River estuary, including water flow, quality, predictions for the estuary’s future, and numerous charts and graphs.
Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
