Diel activity patterns in demersal fishes on Heceta Bank, Oregon

Creator:: Hart, Ted
Abstract:: Most fishes exhibit differences in activity patterns from day to night, with a switch from high to low activity at dusk and reverse at dawn. Marine reef fishes show similar behavior among sites, despite dissimilar species assemblages, suggesting that common selection pressures are leading to convergent behavior. Few studies to...

Rockfish assessment studies on Heceta Bank, Oregon, 1980-81. Sub-project annual report: October 1, 1980 to March 1, 1982

Creator:: Johnson, Steven L., Barss, William H., and Demory, Robert L.
Abstract:: From January 1980 to January 1981 approximate monthly sampling of a unique rockfish (Scorpaenidae) fishing area on Heceta Bank, Oregon was undertaken using acoustic techniques and trawling aboard chartered commercial fishing vessels. Rankings of density of fish sign observed on acoustic transects were regressed against selected environmental variables. Acoustic abundance...

Factors influencing spawning site choice by female Garibaldi, Hypsypops rubicundus (Pisces: Pomacentridae)

Creator:: Sikkel, Paul C.
Abstract:: The garibaldi, Hypsypops rubicundus, is a sexually monochromatic pomacentrid found in rocky subtidal areas of Southern and Baja California. During the spawning season, males attempt to attract females to a nest of red algae located within individually defended territories. Females were observed to enter the nests of several males before...

Seasonal shifts in redband trout use of pools and their microhabitats in three central Oregon streams

Creator:: Hirsch, Christine L.
Abstract:: Redband trout density was examined in three forested streams in central Oregon at two scales, pool channel unit and microhabitat. Two streams were in roadless areas and one was in a "highly managed" watershed. At the larger spatial scale, trout displayed a seasonal shift in habitat use from early to...

Distribution of fishes and their relationships to environments in selected coastal streams, Douglas and Coos Counties, Oregon

Creator:: Duke, Stephen D'Wayne
Abstract:: This study was an investigation to determine the distribution, abundance and general food habits of salmonids and non-game fishes residing in several selected coastal streams, Douglas and Coos Counties, Oregon. The physical conditions that characterize the various stream habitat types were monitored and the influence of physical conditions on the...
