No formal assessment has been conducted and no reference points for long-sustainability have been defined for this data-limited stock. Management of this stock is by technical measures and no Total Allowable Catch (TAC) has been allocated (Devitt et al., 2007; Fisheries of United States, 2014; Hannah and Jones, 2015).

For this stock, the main research priority is to continue examining shrimp population dynamics. Commercial fisheries data should be used to estimate total catch-at-age and effort by area. In addition, a re-evaluation of the fishery’s long-term effects on shrimp population structure should be completed. More information on how recent increases in shrimp density have influenced growth rates, age composition and sex change ratios is required (Hannah and Jones 2015). Research focusing on the use of artificial (LED) lights on trawls to reduce finfish bycatch should be ongoing. Feedback from fishers on how the lights are best installed, maintained and utilised is required (Hannah and Jones, 2015). A better understanding of the effects of the demersal otter trawl fishery on the ecosystem is needed. A camera system should be developed to improve knowledge of the ecosystem effects of fishing (Hannah and Jones 2015).

Historically, the majority of pink shrimp fishing off the west coast of the United States occurred in federal waters (DFW 2007). Since 2007, essentially all of the pink shrimp landings have been in the Eureka area off the coast of Northern California (DFW Commercial Landings Reports 2007-11). Although in recent years the southern beds have been productive, they do not appear to have been fished (DFW, Commercial Landings Reports 2007- 11). It is unclear as to why this may be, but it may be due to low value of the fishery itself and/ or the inability to land pink shrimp at southern ports due to the lack of buyers. There are no enhancements on the west coast to the pink shrimp stock. ODFW estimates the number of vessels and amount of catch caught in federal waters off California and landed in Oregon ports, from logbooks. In recent years this catch and effort was considerably larger than California landings. In 2011, the estimated catch originating in federal waters off California was 10.3 million pounds from 20 vessels and in 2012 it was 9.5 million pounds from 31 vessels. This catch category was under 3.0 million pounds from 2008 through 2010. CDFW does not currently have an estimate of the amount of shrimp caught off Oregon and landed in California ports (DFW Commercial Landings Reports 2007-11).

The status of the pink shrimpstock in the USA exclusive economic zone (California to Washington) has been scored a low risk. This is because the species has a relatively low maximum vulnerability score of 34/100 (Townsend, 2014) and the most recent review indicates that the proxy for stock abundance has increased since 2008. No formal stock assessment is undertaken for this data-limited species.

A risk score was derived for this stock by assuming a worst case scenario and selecting a maximum vulnerability score of 34/100 weighted by the increasing population trend.
