Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:: Crone, Paul R. Jr
Abstract:: Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...

Species composition of rockfish in catches by Oregon trawlers, 1963-93

Creator:: Douglas, David A. and Oregon. Fish Division
Abstract:: This report provides rockfish landings (weight in metric tons) based upon species composition samples taken from commercial trawl landings in Oregon. Rockfish (Family Scorpaenidae) are an important segment of Oregon trawl landings. For over 30 years, the Oregon Department of Fish and Wildlife (ODFW), Marine Finfish Program, previously known as...

Creator:: Demory, Robert L., Barss, William H., and Golden, James T.
Abstract:: “This report summarizes activities from October 1, 1977 through September 30, 1978 (FY 77). Major activities were analysis of data collected from the cooperative coastwide rockfish survey, English sole (Sebastes alutus) tagging in PMFC areas 2B and 2C and lingcod (Ophiodon elongatus) tagging off Newport, Oregon in PMFC area 2c....

Seasonal abundance and behavior of Steller sea lions in Oregon

Creator:: Katalinich, Jennifer D.
Abstract:: Behavioral studies of populations provide clues as to what influences their movements and life history strategies. This is an area of study that has been underutilized in research surrounding the declining western stock of Steller sea lions, Eumet opias jubatus, particularly with regards to haulout behaviors. During the time of...

Study on the vertical distribution and movement of pink shrimp, Pandalus jordani, in the Pacific Ocean off Oregon

Creator:: Milburn, Gary and Robinson, Jack G.
Abstract:: Research cruises were made between August 28, 1967, and June 19, 1968, to study the vertical distribution and movements of pink shrimp, Pandalus jordani, off Tillamook Head in 68-80 fathoms. Shrimp traps suspended from surface to bottom, midwater trawl, and bottom shrimp trawl nets were used. Results are discussed in...

The size of the Oregon coastal salmon runs in the mid-1800s

Creator:: Meengs, Chad C.
Abstract:: Increasing the abundance of salmon in coastal Oregon rivers and streams is a high priority public policy objective. Salmon runs have been reduced from pre-development conditions (typically defined as the 1 850s), but it is unclear by how much. Considerable resources have been allocated to restoring salmon runs, but it...

Comparison of methods to estimate population density of Pacific giant salamanders in small streams of the southern Oregon Cascades

Creator:: Leuthold, Niels C.
Abstract:: I compared hand sampling, two-pass multiple removal sampling, mark-recapture and catchability-based population estimates for the Pacific giant salamander (Dicamptodon tenebrosus) at 22 sites in 11 streams of Cascade Mountains of Oregon. Mark-recapture and catchability-based population estimates were not significantly different (p 0.86). Hand sampling and two-pass multiple removal population estimates...

Habitat availability, dietary mineral supplement, and measuring abundance of band-tailed pigeons in western Oregon

Creator:: Sanders, Todd Alan
Abstract:: My objectives were to: 1) develop a point count technique for estimating relative abundance of band-tailed pigeons (Columbafasciata monilis), 2) determine the availability, distribution, and interspersion of mineral sites, and nesting and foraging cover in relation to abundance of band-tailed pigeons in west-central Oregon, and 3) test the hypothesis that...

Study on the distribution and abundance of pink shrimp, Pandalus jordani, in the Pacific Ocean off Oregon, 1966/1967

Creator:: Robinson, Jack G. and Oregon. Fish Commission
Abstract:: “During the report period, two survey cruises were completed off Oregon; 96 tows were made in the fall of 1966 and 173 in the spring of 1967. Cruise reports were written for each cruise. In addition, logs showing tow location, length, catch, and other data were distributed to interested fishermen...
