Book excerpt: "This report presents the results of the initial four surveys of a continuing series of Green Sea Urchin (Strongylocentrotus droebachiensis) surveys, undertaken jointly between Fisheries and Oceans Canada (DFO) and industry (West Coast Green Urchin Association - WCGUA) in Haro Strait, British Columbia, between March 2008 and March 2010. These surveys are complementary to a similar continuing series of Green Sea Urchin surveys conducted in Queen Charlotte Strait, originating in October 1995. Data were collected by SCUBA divers using the transect-quadrat method, and include information on size and abundance of Green Sea Urchins, gonad weight and quality, and on the depth and substrate. The long-term objectives are to assess variability in Green Sea Urchin populations over time to monitor harvest impacts"--Abstract, p. vii.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: DFO Fisheries Management has requested advice for the Green Sea Urchin fishery in British Columbia (BC), by spring 2016, on the following: 1. The ranges of sustainable harvest options for the commercial harvest areas (Pacific Fisheries Management Areas (PFMAs) 12, 13, 18 and 19); 2. The risks or uncertainties associated with the range of harvest options; 3. The recent trends in the local populatio [...] Markets have improved recently and 82% and 67% of the TAC was achieved in the 2013-14 and 2014-15 fishing seasons, respectively. [...] The TRPs are defined as various reductions from the estimated median of the MSY posterior distribution, along with the probabilities that the TRPs may be larger than the true MSY (Table 1). [...] Table 1. Target reference points (TRPs) in metric tonnes as reductions from the estimated median maximum sustainable yield (MSY), the % probability the target reference point (TRP) may be greater than or equal to the true MSY, and allocation of the total quota to each of the two fishing regions: (A) PFMAs 12 and 13 and (B) PFMAs 18 and 19. [...] For instance, the model assumes that surplus production (amount of increase in biomass of the stock) at any given year is related to the biomass in the previous year, without considering a time lag for larvae or juveniles to grow before contributing to the harvestable biomass.

This book was released on 2015 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Red Urchin Analysis Program (RUAP) and Green Urchin Analysis Program (GUAP) are computer programs that were developed to support stock assessment activities on the west coast of Canada. The Red Sea Urchin (Mesocentrotus franciscanus) and Green Sea Urchin (Strongylocentrotus droebachiensis) stocks in British Columbia (BC) are assessed every three years through the analysis of fishery-dependent and fishery-independent data. This document describes how the calculations within RUAP and GUAP estimate urchin biomass and population densities from fishery-independent survey data for defined geographic areas.--Includes text from document.
