Some sea otter populations went extinct, including those in Oregon and British Columbia. Overall viewing conditions this year were very good, better than those encountered during the 2018 spring census (View Score = 3.0 this year compared to 2.4 last year, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent). Since the end of the fur trade, sea otter numbers are believed to be down to 1,000 to 2,000 worldwide… Southern Sea Otter. Overall viewing conditions this year were very good, better than those encountered during the 2018 spring census (View Score = 3.0 this year compared to 2.4 last year, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent). “That means they have a bigger effect than almost any other animal for their size on their ecosystems,” said USGS Western Ecological Research Center Research Biologist Tim Tinker. He recently published a paper estimating that Southeast Alaska’s carrying capacity could be three times the present population. For one, they can’t just open a hunt on sea otters. The range-wide census is conducted to monitor trends in abundance of the southern sea otter, and thus provide State and Federal resource agencies with the information they need for effective management. The otters are covered by the Marine Mammal Protection Act. After a day-long meeting in Juneau, wildlife and fisheries managers, fishing industry and tribal representatives formed committee to recommend ways to manage the species. The southern sea otter population has plateaued in recent years (Tinker and Hatfield, 2018) and natural range expansion is currently restricted by the distribution of kelp forests due to increased predation on otters in areas with low kelp cover (Moxley et al., 2019; Nicholson et al., 2018). These otters were cared for using the aquarium’s resident sea otters as surrogate mothers, and then released as juveniles into Elkhorn Slough. Study data were based on the releases of 37 sea otter pups rescued by the Sea Otter Program from 2002-2016. Their primary food source includes shellfish. The continuing conflict between fishermen and sea otters is not new. Professional and amateur athletes alike make the annual pilgrimage to Sea Otter to participate in some of the sport’s most competitive and enduring events. Alaska Department of Fish and Game’s Fishery Biologist Kyle Hebert said state fisheries managers have a hard job managing commercial stocks depleted by foraging otters. Then in 1914 a remnant population of about 50 southern sea otters was found along the rugged Big Sur shoreline. Since then, they’ve done really well. Efforts to ease conflicts over Southeast Alaska’s growing sea otter population are underway. The most recent assessment estimates a population size of 54,771 individuals, with a minimum population size of 45,064 (Muto et al. The conservation and management of sea otters has benefited from a dedicated research effort over the past 60 years enabling this species to recover from a few thousand in the early 20th century to about 150,000 today. The surface canopies of kelp (predominantly Macrocystis pyrifera) were qualitatively noted by observers to be much less than the seasonal normal in the central portions of the range (from Monterey to Cayucos) and about normal near both ends of the range. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Population. “There’s no simple solution,” Tinker said. Ranges from Attu Island east to the Kodiak Archipelago and the Barrren Islands, and north to the Pribilof Islands (Gorbics and Bodkin 2001). A draft is expected by the end of the year. 41 years later and counting, their conservation status remains unchanged and their future uncertain. Sea otters along the mainland coast were surveyed from Pigeon Point in San Mateo County in the north, to Santa Barbara Harbor in Santa Barbara County in the south. He recently published a paper estimating that Southeast Alaska’s carrying capacity could be three times the present population. That’d be around 75,000 sea otters over the next 30 to 40 years. The 3-year average counts are used by the US Fish and Wildlife Service in its listing determinations (de-listing or up-listing) for this legally threatened population. The otters, whose population rose to nearly 26,000 in the latest assessment updated in 2014, are under federal protection and managed by the U.S. The spring 2019 mainland sea otter count began on May 1 and was completed by July 9. Southern sea otters, also called California sea otters, live in waters along the California coastline, ranging from San Mateo County in the north to Santa Barbara County in the south. The sluggish recovery of the southern sea otter of California, a threatened population on the Endangered Species list, appears to have stalled once again. In addition, the location already supported a small population of male sea otters. Results from this year’s (2019) sea otter population count have revealed the population has dropped to 2,962 individuals, below the threshold.

U.S. Nor is it limited to Alaska. These sea otters belong to … The grants will be funded by the California Sea Otter Fund, which is one of the state’s voluntary tax check-off funds that allows taxpayers to contribute additional money for use towards the recovery of California sea otter populations. Brent Hughes, assistant professor of biology at Sonoma State, is the lead researcher in a new study concluding that California could more than triple its population of southern sea otters. “So from an economic point of view, these dive fisheries are important.”. Today the population hovers around 3,000 individuals, with a large segment of that population in Central California waters. That’d be around 75,000 sea otters over the next 30 to 40 years.

The reduction in population is consistent with observations of elevated shark-bite mortality in the northern and southern regions of the otter’s range. Mar. Fish and Wildlife Service’s Chief of Marine Mammals Management in Alaska Patrick Lemons said a looming political impasse in Washington D.C. could set things back. Instead, these data represent a valuable time-series of index counts, and provide the means of assessing spatial and temporal trends in relative abundance. That means they can only be hunted by coastal Alaska Native people for subsistence or traditional crafts. Phil Doherty, executive director of the Southeast Alaska Regional Dive Fisheries Association, said that when you add up all of divers, the deckhands, tenders and processors on the slime line, it’s significant for the winter economy.

Collectively these are known as Southeast Alaska’s dive fisheries and last year they brought in about $12.4 million. The State Coastal Conservancy is now accepting applications for its 2020 Sea Otter Recovery Grants. Because the censuses represent uncorrected total counts (rather than sample-based surveys), they cannot be considered as accurate estimates of true population abundance. U.S. Geological Survey scientists say the latest 3-year average (2,813 sea otters) was 0.5 percent lower than last year, the first time the trend has been negative since the late 1990s. “Many of those effects are really disruptive to the existing, you know, commercial activities like shell fisheries that have developed.”. Overall viewing conditions this year were very good, better than those encountered during the 2018 spring census (View Score = 3.0 this year compared to 2.4 last year, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent). Once containing more than half of the world’s sea otters, this population segment, which ranges from Kodiak Island through the western Aleutian Islands, has undergone an overall population decline of at least 55–67 percent since the mid-1980s.

But researchers say it may draw away attention from the value of other habitat — estuaries — that could truly help the endangered species in its recovery. The spring 2019 mainland sea otter count began on May 1 and was completed by July 9. Federal and state officials recently met with scientists, fishermen and tribal groups in Juneau to find solutions. A study from the University of California, Davis, identifies the parasite’s specific strains that are killing southern sea otters, tracing them back to a bobcat and feral Reduced range and population size, vulnerability to oil spills, and oil spill risk from coastal tanker traffic were the primary reasons for listing. But even if federal and state managers wanted to curb the growing sea otter population, their options are limited. The 3-year running average of the spring counts have been identified as the best index of trends and status of the population, because these averages decrease the influence of year-to-year sampling variance. Since then, sea otter populations have rebounded, but the International Union for Conservation of Nature (IUCN) lists the species as a whole as Endangered.
