Includes bibliographical references (pages 25-26). "The Precautionary Approach (PA) is a general philosophy to managing threats of serious or irreversible harm where there is scientific uncertainty. An implementation of this approach, in the form of the PA Framework, serves as a foundation for the establishment of Limit Reference Points (LRPs), below which productivity is sufficiently impaired to cause serious harm to a fishery. Fisheries and Oceans Canada (DFO) has committed to implementing a PA Framework in the management of the Northern (Pandalus borealis) and Striped (P. montagui) shrimp fisheries located in Hudson Strait and Ungava Bay (Western Assessment Zone; WAZ). To support these efforts, this document provides directions for establishing of LRPs and suggests the Upper Stock Reference Points (USRs) for these stocks. This document also discusses updated LRPs and suggests USRs for the Northern and Striped Shrimp fisheries in Davis Strait (Eastern Assessment Zone; EAZ). Two approaches to establishing the LRPs are considered herein: 30% and 40% of the geometric mean of female spawning stock biomass (SSB)"--Abstract, page iv.
