Abstract
The status of Northern Shrimp (Pandalus borealis) in Shrimp Fishing Area (SFA) 4 has been assessed annually since 2015 and was last assessed in February 2022. The status of Striped Shrimp (Pandalus montagui) in SFA 4 is assessed on a biennial basis. It was last assessed in 2021 and a stock status update was conducted in 2022. In SFA 4, the statuses of both stocks have been assessed by examining multiple indicators derived from the fishery-dependent data and the Northern Shrimp Research Foundation (NSRF) - Fisheries and Oceans Canada (DFO) research survey data. Despite a year-over-year decrease of the Northern Shrimp Fishable Biomass (FB) and female spawning stock biomass (SSB) indices in 2022, the recent trend suggests continued increases from a historic low in 2018. In 2022, Northern Shrimp in SFA 4 was in the Healthy zone within the Precautionary Approach Framework, just above the Upper Stock Reference, with a 53% probability of being in the Cautious Zone. Striped Shrimp FB and SSB indices in SFA 4 have increased since 2021 and are above the long-term means (2005–21) of the survey time series. In 2022, Striped Shrimp in SFA 4 is considered in a healthy state in the PA framework (5 times the Limit Reference Point) and other indices of stock health, including the potential predator index, total egg production index, and SFA 4 specific fishable biomass index showed no cause for concern.
