Hot off the press … new ecological and human dimensions research journal publications and information reports by the ODFW Marine Reserves Program.
Three recent ODFW Information Reports, with contributions made by ODFW Marine Reserves Program staff, have focused on advancing scientific research methods.
New Methods For Estimating Fish Age And Growth
A report exploring new methods for estimating age and growth of Cabezon. In addition to the typical data gathered on adults from commercial and recreational fisheries it incorporates juvenile fish data, collected in marine reserves monitoring, into the growth rate estimates. This is the first-time juvenile fish data have been included in the Cabezon stock assessment.
- Age reading of Cabezon (Scopaenichthys marmoratus): 1) comparison of thin-section and break-and-burn methods and 2) comparison of growth curve fits.
Which Tools Are Best For Monitoring Temperate Reef Fishes
A report comparing three of ODFW’s core marine reserve monitoring tools — hook-and-line, video lander, and SCUBA — exploring which are most efficient for monitoring temperate reef fishes.
- Comparing angling, underwater visual census, and video methods to refine [fishery independent] long-term monitoring of a reef fish assemblage in a temperate marine reserve.
What Have We Learned From 9 Years Of Using Video Landers
A collaboration with the ODFW Fisheries Research and ODFW Nearshore projects, this report summarizes nine years of using video landers to study temperate reef fish off the Oregon coast. This effort informs discussions about fishery independent surveys in untrawlable rocky habitats and the potential to use such data in stock assessments.
- Nine years of video landers at the Oregon Department of Fish and Wildlife’s Marine Resources Program.
Human Dimensions Research
3 Journal Publications
A recent publication authored by ODFW Marine Reserves Program staff highlights novel research approaches for investigating marine reserve socioeconomic impacts:
- Fox, H.K., and T.C. Swearingen. 2021. Using a difference-in-differences and synthetic control approach to investigate the socioeconomic impacts of Oregon’s marine reserves. Ocean and Coastal Management 215: 105965.
Two additional recent publications, with contributions from our staff:
- Insinga, M. L., M.D. Needham, & T.C. Swearingen. 2022. Public emotions and cognitions in response to ocean acidification. Ocean and Coastal Management 221:106104.
- Insinga, M. L., Needham, M. D., & Swearingen, T. C. (Published online March 2023). Public cognitions and emotions associated with sea star wasting disease: An exploratory study in Oregon. Human Dimensions of Wildlife 28(4).
And, three recent reports produced by our program looking at socioeconomic impacts of Oregon’s marine reserves:
- Oregon Marine Reserves 2021 Visitor Intercept Survey: A Comparative Analysis to Baseline 2011 to 2015 Data
