This book was released on 2016 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated assessments are a tool that can help decision makers understand complex environmental problems. Climate change has the potential to impact managed resources in terms social and economic factors, as well as causing changes to biogeochemical cycles and subsequent changes to species that these cycles affect. The U.S. west coast red sea urchin (Strongylocentrotus franciscanus) fisheries stand to be affected by climate change-related stressors such as ocean acidification, rising ocean temperatures, and changes in the frequency and intensity of ENSO events. An integrated assessment of the institutional and ecological contexts of two red sea urchin fishery case studies outlines existing knowledge gaps that may impede management efforts when it comes to the sustainability and vulnerability of these marine resources under threats from climate change.

Available in PDF, EPUB and Kindle. Book excerpt: A survey of red sea urchin populations was conducted in Fitz Hugh Sound (Pacific Fisheries Management sub-areas 8-3, 8-4, and 8-16) during August, 2001. A total of 60 transects were surveyed by SCUBA divers, and 1157 red sea urchins were measured. The total mean density of red sea urchins of all sizes was 1.49/m2, and for legal-sized red sea urchins, the density was 0.72/m2.

Available in PDF, EPUB and Kindle. Book excerpt: A survey of red sea urchin populations was conducted near Robson Bight (Pacific Fisheries Management, PFM sub-areas 12-3 and 12-21) during 2001. A total of 60 transects were surveyed by SCUBA divers, and 957 red sea urchins were measured. The density of red sea urchins in PFM sub-area 12-3 and in PFM sub-area 12-21 for red sea urchins of all sizes was 0.83/m2 and 0.63/m2, respectively, and for legal-sized red sea urchins, the density was 0.69/m2 and 0.53/m2, respectively. No significant differences were observed in estimated mean density (number/m2) and biomass (g/m2) between red sea urchins found inside(12 transects) compared with outside (48 transects) previously fished commercial bed areas.
