The identification of provisional reference points and harvest rate options for the commercial red sea urchin (Mesocentrotus franciscanus) fishery in British Columbia.: Fs70-6/2019-036E-PDF

"The Red Sea Urchin (Mesocentrotus franciscanus) (RSU) fishery in British Columbia (BC) is currently managed using an annual harvest rate of 2% (Leus et al. 2014). This harvest rate was derived using a modified Gulland surplus production model; a model used when a stock is data limited and in the early stages of exploitation (Gulland 1971). The RSU fishery is no longer in the early stages of exploitation, commercial harvesting has been occurring for 48 years. To date, almost 25 years of urchin density and size data have been gathered through fishery-independent dive surveys. These data and the exploitation history of the fishery warrant a re-evaluation of the 2% harvest rate through the development of new models. Further, the existing RSU harvest strategy lacks reference points that reflect conservation thresholds required under DFO's Sustainable Fisheries Framework (DFO 2009a)."--Context, page [1].
