"This information report provides an updated summary of all coastal shad tagging studies conducted by the Fish Commission. I believe these studies represent the only shad tagged in Oregon coastal streams south of the Columbia River. No new field work is reported. My intent is to tabulate, consolidate, update, and...
"Striped bass (Morone saxatilis) were tagged on the Umpqua and Smith rivers (Figure 1) to estimate the numbers of bass recruited to the commercial fishery and to gather information on migration habits of bass in these rivers. Small numbers of striped bass were tagged in the summers of 1971 and...
A tagging study was conducted from June 1978 through January 1982
to provide information on the movements of adult neritic reef fishes
off the central Oregon coast. To evaluate the cause of low tag
returns of previous tagging studies of reef fish in this area, tag
retention, post-tagging mortality, and...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
During a tagging operation conducted in 1951 on the Alsea River, 1,142 adult silver salmon were tagged with plastic Petersen-type tags and stainless steel jaw tags. An attempt was made to determine whether tagged fish released in different apparent conditions suffered differential mortalities. Under the hypothesis that the recovery of...
In July and August 1961, nine lots of 500 juvenile silver salmon each were subjected to one-, two-, three- and four-week periods of complete starvation. The three- and four-week periods produced the best growth checks for that time of year, but were generally of inferior quality to those produced in...
This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...
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...
The movement of Chinook salmon through space and time, across political boundaries, and through fisheries, creates one of the most complex marine resource management problems in the world. Information garnered from the recovery of coded-wire tags (CWTs) has been used since the 1970s to direct management decisions. Growing concern surrounding...
The disposal of radioactive waste products is a serious problem facing scientists and the public. One solution proposed is to dump these waste products at sea, with the area of northern Oregon and southern Washington in 100 to 1,000 fathoms as one area of consideration. However, one of the problems...
