2003; Miller et al. Sea otters and kelp forests in Alaska: generality and variation in a community ecological paradigm. Four feedback forms were received, including comments from academic, ENGO, and industry representatives. Canadian Technical Report of Fisheries and Aquatic Sciences 2677: viii + 188 pp. As a result, restrictions in the use of gill and trammel nets in waters less than 65 metres were implemented and the population decline reversed (Riedman and Estes 1990). The laws as currently written, she adds, overlook “how crippling it is to not be able to do anything.”, That’s not to say that some locals aren’t taking matters into their own hands. The assigned prioritization of each measure may change with time as new information emerges. Molecular Ecology 11:1899-1903. 2005). 2005. Officers also work with local First Nations to promote Sea Otter conservation. 2000a). Sea Otters are considered a keystone species exerting significant ecological effects on nearshore marine communities and upon the life history of their prey (Estes and Palmisano 1974; Estes et al. 2009). Watson, J.C. 1995. Unoccupied habitat is sequentially occupied as the number of Sea Otters in an area approaches carrying capacity. The interaction between contaminant burden and disease is considered a possible factor in the high rate of disease-caused mortality in the southern Sea Otter population (Thomas and Cole 1996; Reeves 2002; Ross 2002). 2005; Brancato et al. 2012). These observations suggest that there may be limited seasonal movement. Prepared for: Habitat Stewardship Program. 2003. Since the Species at Risk Act came into force, DFO’s Conservation and Protection Branch has dedicated over 1000 hours specifically to Sea Otter protection and enforcement in Canadian Pacific waters. It has been placed Ellison, J.J. Finneran, R.L. J. Stockdale and G. Goulding, London, United Kingdom. The introduction of both CDV and PDV highlight the potential role of growing human population densities in coastal marine areas and the potential effect of climate change. Research activities may include: Communication to the public and others is important to promote understanding and support and for the need to protect Sea Otters. DFO Canadian Science Advisor Secretariat Research Document 2009/016. They swim belly up with their front paws in the air, using the webbed hind feet for propulsion. 1990. Esslinger, K.A. During periods of extended inclement sea and weather conditions available foraging habitat may be limited. Queen’s Printer, Victoria, BC. Maselko, M.R. Sea otters came under international protection in 1911 and since then, their numbers have rebounded. Growth rate slowed to about 8% per year thereafter on Vancouver Island and has been about 11% per year on the central British Columbia coast. Vertical distribution and probability of encountering intertidal Exxon Valdez oil on shorelines of three embayments within Prince William Sound, Alaska. The Sea Otter has been assigned Endangered status by the Committee on the Status of Endangered Wildlife in Canada (cosewic), and receives legal protec-tion as a marine mammal under the Canada Fisheries Act. As this is an emerging threat, it is anticipated the level of concern will likely increase in the event that directed harvest is approved. A method has been developed for calculating an allocation for this harvest from the total allowable harm estimate that considers other sources of human induced mortality such as illegal killing, entanglement and vessel strikes. The river otter (Lutra canadensis) occurs throughout N America except in desert and arid tundra regions.In Canada it is scarce, except along the BC coast, where it is abundant and often wrongly identified as a sea otter.. Phocine Distemper Virus in Northern Sea Otters in the Pacific Ocean, Alaska, USA. Figure 1: Sea otter population measured off the coast of Vancouver Island Sea otters once ranged from Northern Japan to central Baja California, and had an estimated global population of between 150,000 and 300,000. Southern sea otter contaminants working group. In the British Columbia samples, exposure to T. gondii was found in live captured animals (DFO Sea Otter program unpubl.)
