At a recent meeting of the NAFO Scientific Council participants considered three example stocks for the application of precautionary methods, including one "data poor" stock i.e. shrimp (P. borealis) on Flemish Cap (NAFO Division 3M). For stocks such as 3M shrimp for which quantitative reference points, targets or limits could not be defined, Scientific Council endorsed the interim use of stock specific checklists which include multiple, qualitative indicators of resource status. This method, which is similar to the matrices used in Environmental Impact Assessment, uses the "Traffic Light" analogy because assessment results are categorized as "green", "yellow or "red", corresponding to favourable, uncertain or unfavourable stock conditions. Recent stock assessments for Atlantic Canadian shrimp stocks, including the Scotian Shelf, the Gulf of St. Lawrence and the Labrador-Newfoundland Shelf, were conducted using the Traffic Light/checklist approach and results were viewed positively by scientists (some), fisheries managers and industry. A major drawback of the method in its current form is that it does not link assessments to TACs or other management controls. Modeling results suggest that "Traffic Light" results could be linked to simple harvest control rules in a way that is consistent with shrimp stock dynamics and management requirements, creating an integrated management framework. Introduction Assessment and management for many Pandalus borealis stocks in the Northwest Atlantic can be surprisingly ad hoc in that there are few clearly stated management objectives, biological reference points or harvest rules. Notwithstanding theoretical considerations, past experience and socio-economic pressures which result in undefined limits inherent in the scientific\management “culture” of any particular fishery, each change in TAC is essentially an
