Description

Abstract: Periodically evaluating the effects of fishing and the environment on population structure and recruitment is critical to assuring sustainability in a fishery. Oregon’s ocean shrimp (Pandalus jordani) trawl fishery is managed as a sustainable fishery and was the first shrimp fishery certified as “sustainable” by the Marine Stewardship Council (MSC). In accordance with MSC recommendations, the Oregon Department of Fish and Wildlife (ODFW) published reports in 2014, 2016, 2018, and 2021 evaluating recruitment effects for ocean shrimp, for the purpose of documenting ongoing monitoring and analysis (Hannah and Jones 2014, Hannah and Jones 2016, Groth and Hannah 2018, Groth et al. 2021). In this report, we build on previous work by adding two additional years of data and discuss new issues that affect the ocean shrimp stock and fishery. These long-term datasets and analyses provide us metrics that allow us to have confidence in the sustainability of Oregon’s ocean shrimp fishery. This report series (population structure and recruitment of ocean shrimp) was developed by Hannah and Jones (2014) as a template to add future data to and maintain continuity in the reevaluation of fishery parameters (Hannah, pers. comm. 2018). Suitable periodicity of testing recruitment model performance was determined to be each two years, while testing fishery effects to the population structure (e.g., average size at age) is expected to be more appropriate at a 10-year interval (future analysis scheduled for 2028). ODFW has effectively monitored, researched, and managed Oregon’s ocean shrimp fishery, helping Oregon’s ocean shrimp fishery maintain MSC sustainability certification. This report purposefully borrows heavily from previous reports in this series to provide continuity in the analytical methods and update datasets in an organized and uniform way.
