© 1996-2015 National Geographic Society, © 2015- NOAA Fisheries conducts observational studies using photo-identification and other techniques to understand the behavior and population dynamics of beluga whales, as well as threats against them. In response to a petition, NOAA Fisheries conducted a status review of the stock and designated it as depleted under the MMPA in 2016. Beluga whales are known for their white color and range of vocal sounds, earning them the title of \"canary of the sea.\" They are very social animals, forming groups to hunt, migrate, and interact with each other. In 2016, we also completed a Species in the Spotlight 5-year plan of action for the Cook Inlet beluga whale that builds on the recovery plan and details the focused efforts that were needed over the next 5 years. NOAA Fisheries has issued an incidental harassment authorization (IHA) to Crowley Fuels, LLC to incidentally harass, by Level B harassment only, marine mammals during construction activities associated with the Crowley Kotzebue Dock Upgrade in Kotzebue,…, NOAA Fisheries has issued two successive incidental harassment authorizations (IHA) to the Port of Alaska (POA), authorizing the take of small numbers of marine mammals incidental to construction of the Petroleum and Cement Terminal (PCT), Anchorage…, NOAA Fisheries has issued an incidental harassment authorization (IHA) to the Office of Naval Research (ONR) to incidentally harass, by Level B harassment only, marine mammals during Arctic Research Activities in the Beaufort and Chukchi Seas. Notably, past harvest practices have significantly impacted the Cook Inlet beluga whale population. Belugas generally give birth during summer in areas where the water is relatively warm, as newborn calves lack a thick blubber layer to protect them from cold water. Historical reports indicate that beluga intestines are approximately seven times the length of their body (Morrison Watson, 1880; Jefferson et al., 1994). This yellowy hue is soon lost during summer moulting though â a rather unusual event for cetaceans â restoring them to their pearly glow. Belugas are known as the "canaries of the sea" because they produce many different sounds, including whistles, squeals, moos, chirps, and clicks. The beluga is also known as the white whale for its milky white skin. This includes monitoring subsistence harvests and conducting abundance and distribution surveys. Arctic belugas migrate southward in large herds when the sea freezes over. Based on the intestinal sub-section MP counts, we estimated total MP abundance per whale by calculating the mean number of MP per meter of intestines and extrapolating this data. Whale of a time! Unlike other whales and dolphins, their neck vertebrae are not fused, so belugas can nod and move their heads from side to side. They have rounded foreheads and no dorsal fin. Learn more about Joint Base Elmendorf-Richardson's work. Reviewing projects that could harm beluga whales. Calves are born gray or even brown and only fade to white as they become sexually mature around five years of age. The female Beluga always gives birth to one calf and nurses it until itâs two years of age. Smell. The Cook Inlet Beluga Whale (CIBW) Photo-ID Project began in 2005 and continues to the present day, conducting surveys of Cook Inlet belugas and developing a photo-identification catalog of individuals. 22629, Mystic Aquarium), Permit No. Beluga whales are robust and stocky with thick folds of blubber. The beluga is also called the white whale because of its milky white skin, and is the only whale species that is completely white. Measurements of response to sound using digital acoustic recording tags. Cook Inlet belugas were once a valuable part of the regional Alaska Native subsistence diet, but their population has declined rapidly—most likely because of unregulated subsistence harvest at a level that this small population could not sustain. Underneath the water, the different environments in the bay are spectacular. They are at home in large rivers and can move between salt and fresh water. Similar to tree rings that can be used to age a tree, beluga teeth acquire a “growth layer group” (GLG) for each year they age. In Alaska, scientists and Native subsistence hunters have worked together to place satellite tags on belugas. Minimizing the effects of noise disturbance. The minke whale / Ë m ɪ n k i /, or lesser rorqual, is a species complex of baleen whale. The plan recommends the following major actions: Protect habitat and designate critical habitat. The CIBW Photo-ID Project was established and developed through funding from a combination of NGOs, industry, agencies, research foundations and Tribes, including from NOAA Fisheries beginning in 2012. The males can weigh up to 3,500 pounds with the females smaller at around 2,600. https://www.nationalgeographic.com/animals/mammals/b/beluga-whale.html. 22629-01 Minor Amendment (PDF, 6 pages), NOAA Fisheries Approval of the Breeding Prevention Plan (PDF, 3 pages), Permit No. Belugas also have sharp vision both in and out of water. The blubber keeps them warm in the Arctic waters and stores energy. Implement oil spill response plans in the event of a spill. She had been assisting with pinniped research and coordination until spring 2017 when a call went out for someone from the state to partner with us for the inaugural Belugas Count! Satellite tagging and tracking of movement, range, and distribution. Targeted management actions to secure beluga whale protections include: Protecting habitat and designating critical habitat in Cook Inlet. Worldwide, belugas may number in the hundreds of thousands; however, some stocks are small, numbering in the low hundreds. All beluga whale populations are protected under the Marine Mammal Protection Act. Every day is new; every minute is new. It is gray when born, this color fading gradually with age. Only the Cook Inlet beluga whale population is listed as endangered under the Endangered Species Act. Each stock is unique, isolated from one another genetically and/or physically by migration routes and preferred habitats. Be responsible when viewing marine life in the wild. NOAA Fisheries has designated the Cook Inlet beluga whale population in Alaska and the Sakhalin Bay-Nikolaya Bay-Amur River stock off the coast of Russia as depleted under the MMPA (i.e., they have fallen below their optimum sustainable population levels). The Cook Inlet Beluga Whale (CIBW) Photo-ID Project began in 2005 and continues to the present day, conducting surveys of Cook Inlet belugas and developing a photo-identification catalog of individuals. In 2011, we designated two areas of Cook Inlet as critical habitat because they are essential for the beluga whalesâ survival. They return to their birth areas each summer to hunt, breed, and calve. Once in the environment, these substances move up the food chain and accumulate in predators at the top of the food chain such as beluga whales. This puts a larger portion of the endangered population near the most densely populated area of the state during the busy summer season, when boating, construction, and other human activities all increase. Depending on the population, this may occur during migration or in their wintering grounds. In the United States, NOAA Fisheries works to protect all beluga whale populations living off the coastlines, bays, and rivers of Alaska. The Joint Base Elmendorf-Richardson, Environmental Element, Natural Resources Section's Cook Inlet Beluga conservation program epitomizes the cooperative spirit of the Species in the Spotlight initiative. We regularly share information with the public about the status of belugas, as well as our research and efforts to promote their recovery. Review projects that could harm beluga whales. event. There are less than 100,000 individuals in the world, so efforts must be taken seriously. NOAA Fisheries has issued a Renewal incidental harassment authorization (IHA) to the U.S. Navy’s Office of Naval Research to harass marine mammals incidental to Arctic Research Activities in the Beaufort and Chukchi Seas. Pregnancy rates showed signs of decline after age 40 in the eastern Chukchi Sea females and at around 46 years old in northwest Alaska.

Aerial view of beluga whales in the Chukchi Sea. Beluga feed on fish, crustaceans, and worms. By doing hexacopter photography surveys each year in late August or early September, we hope to monitor calf production and compare that to environmental factors, such as the strength of salmon runs in a given year—an important food source for belugas. Larger belugas with compromised immune systems also may not survive stranding through a tidal cycle. This international project helped us learn more about the behavior and life history of belugas. Beluga Whale Family. Minimize the effects of noise disturbance. With flawless white camouflage and a superior echolocation system, these sociable Arctic singers have adapted perfectly to life under the ice. We also set in-water construction guidelines that outline which noise levels are harmful to beluga whales. This can range from physical barriers that limit their access to important migration, breeding, feeding, or calving areas, to activities that destroy or degrade their habitats. In 2000, NOAA Fisheries designated the Cook Inlet beluga whale population as a Candidate Species under the Endangered Species Act and as depleted under the Marine Mammal Protection Act. The oldest female beluga whale from Cook Inlet was 47 years old and appeared to have recently given birth. In 2013, the recovery team provided a first draft of the recovery plan and the team disbanded. Overfishing, habitat changes, and the impacts of climate change can decrease the amount of food available to beluga whales. He then dug a pit underneath the other adult whale to turn it to the right position, and spent the next seven hours scaring away birds and dogs from the whales, trying to calm them down and keeping their eyes wet. Underwater noise pollution interrupts the normal behavior of beluga whales, which rely on sound to communicate and echolocate. Habitat impacts, They migrate seasonally, and calves will learn the migration patterns from their parents. Beluga subsistence harvest in the Cook Inlet of south-central Alaska is now regulated because of the lack of recovery in the area. The MMPA allows NOAA Fisheries to enter cooperative agreements with Alaska Native organizations to conserve marine mammals and co-manage subsistence activities, including beluga whale hunts. They are found in frigid Arctic and sub-Artic seas almost worldwide. Beluga whales are vulnerable to many stressors and threats, including pollution, habitat degradation, predation from killer whales, harassment, interactions with commercial and recreational fisheries, oil and gas exploration, disease, and other types of human disturbance such as underwater noise. In Cook Inlet, Alaska, we review permits for anthropogenic activities and suggest ways to decrease the amount of noise they create. These whales are common in the Arctic Ocean's coastal waters, though they are found in subarctic waters as well. This is of particular concern for the Cook Inlet population, which inhabits an area with high vessel traffic, oil and gas exploration and development, dredging and pile-driving, military operations, and other noise-making anthropogenic (human-caused) activities. This research helps us understand the threats that belugas and their prey face when harmful substances are spilled in Cook Inlet. Contaminant releases may also degrade habitat. During other seasons, they may be found in deeper waters, diving to 1,000-meter depths for periods of up to 25 minutes. Body Shape. Once a species is listed under the ESA, NOAA Fisheries evaluates and identifies whether any areas meet the definition of critical habitat. The summer range of Cook Inlet belugas has changed significantly since the 1970s, contracting northward and eastward toward Anchorage in upper Cook Inlet. The gestation period for the Beluga Whale is about 14 to 15 months. Other research focuses on the acoustic environment of cetaceans, including beluga whales. Belugas also lack a dorsal fin so that they can swim under ice. The best result is that Benny goes missing, tingeing its continuing fame with sadness Learn more about aerial surveys in Cook Inlet. Improving our understanding of the effects of threats to Cook Inlet belugas. Developing oil spill response plans in the event of a spill. The oldest Cook Inlet beluga whale had 49 GLGs. NOAA Fisheries is working with Native communities to implement regulations that limit the number of belugas harvested in Cook Inlet, thus providing continued opportunity for traditional subsistence activities while also allowing the population to recover. Especially loud underwater sounds can kill marine mammals, but sublethal effects are more common, including injury or behavioral changes that range from mild (e.g., increased vocalizations) to severe (e.g., abandonment of vital habitat). Between 1999 and 2005, Alaska Natives only took five Cook Inlet beluga whales through subsistence harvest before it was suspended entirely. The priority actions for Cook Inlet Belugas are: In the first five years of Species in the Spotlight, we have taken important steps toward finding out more about what we can do to stabilize this species and prevent its further decline. The strap was branded with 'equipment of St. Petersburg' and featured a mount for an action camera. Tracks the implementation of recovery actions from Endangered Species Act (ESA) recovery plans. White whales are smallish, ranging from 13 to 20 feet in length. We finalized the recovery plan (PDF, 284 pages) in December 2016. NOAA Fisheries scientists are leading the effort to answer key questions about beluga whales, with a special focus on the Cook Inlet population. NOAA Fisheries scientists and their collaborators collect tissue samples to study the chemicals that belugas are exposed to in Cook Inlet. Numerous organizations around the country are trained and ready to respond. Beluga whales are unlike any other whale, dolphin or porpoise. In an effort to promote recovery, the CIB Recovery Implementation Task Force includes three distinct committees which will focus on each of these general topics: a) Research Committee; b) Habitat and Threats Management Committee; and c) Outreach Committee. The recovery plan also identifies specific criteria that will signal the recovery of these animals. In addition, the Cook Inlet distinct population segment has been listed as an endangered species under the Endangered Species Act. Understanding the potential for food limitations to hinder population recovery is especially important for Cook Inlet beluga whales because they live in an area with high human activity. The rapid decline and dire status of the Cook Inlet beluga whale population makes it a priority for NOAA Fisheries and its partners to prevent extinction and promote recovery. Individuals move between groups within these populations, unlike killer whales, which appear to have strong ties within their maternal-led pods. Educating the public about belugas and the threats they face. Beluga whales live in the Arctic Ocean and its nearby seas in the Northern Hemisphere. The whale is related to the tusked âunicornâ whale known as the narwhal. It may have thick folds of blubber, especially along its ventral surface. Animals trapped by Arctic ice often die, and they are prey for polar bears, killer whales, and for Arctic people. Underwater noise threatens beluga whale populations, interrupting their normal behavior and driving them away from areas important to their survival.

The endangered Cook Inlet beluga whale population has declined by nearly 80 percent since 1979, from about 1,300 whales to an estimated 279 whales in 2018. The genus name Delphinapterus translates to “dolphin without a fin.” Instead of a dorsal fin, belugas have a tough dorsal ridge, which allows them to swim easily under ice floes (sheets of floating ice). It is commonly referred to as the beluga, melonhead, or sea canary due to its high-pitched twitter. NOAA Fisheries' stock assessment reports estimate population size for stocks within U.S. waters. The reason for the Cook Inlet beluga's distribution change is unknown, but the Susitna River delta appears to be an important feeding area that continues to be occupied by large gatherings of belugas during the ice-free period. Alexey carried the baby to the mother so that the female beluga stopped worrying, and covered it with his jacket. The designation of an area as critical habitat does not create a closed area, marine protected area, refuge, wilderness reserve, preservation, or other conservation area; nor does the designation affect land ownership. They squeal, squeak, and chirp, which is why sailors long ago called them âsea canaries.â Of the five Alaskan stocks, the Cook Inlet beluga stock is the smallest and most isolated from other beluga whales. Beluga whales are found in the United States in Alaska and globally throughout the Arctic Ocean.
