520 |a“Shrimp biomass indices in Shrimp Fishing Area (SFA) 6 have declined to the lowest levels in the twenty-year survey time series. Science advice (DFO 2014 and DFO 2016) has indicated that a decline in shrimp production has been associated with a recent warming trend, early timing of the phytoplankton bloom, increasing biomass of predatory fishes and commercial fishing. The fishable biomass index is expected to remain low, or decline further, in the short-term assuming that unfavourable conditions continue. Given the changes in environmental conditions and the predatory fish communities on the NL Shelves, Fisheries and Ecosystems Management requested that Science assess risks associated with potential alternative interim reference points on the basis that a maximum harvest rate of 10% will remain in place if the female spawning stock biomass (SSB) index declines below the current Limit Reference Point (LRP) of 82,000 t (i.e. the harvest control rule currently in place). Consequently, a DFO Science Response Process (SRP) was undertaken on January 25, 2017. No new data since the 2016 Regional Peer Review of the Assessment of Northern and Striped Shrimp (DFO 2016) were available for review. An assessment model and subsequent revised PA framework will be explored, and peer-reviewed at a framework meeting in 2-3 years"--Context, p. [1].
