Whale watching has become an important recreational industry in several communities along the North American coast from British Columbia, Canada, to the gray whale wintering lagoons of Baja California, Mexico. Here are some tips to avoid collisions: Keep a sharp lookout. Their well-known migrations take them between feeding and breeding areas, swimming as much as 12,000 miles round trip. NOAA works with the U.S. Coast Guard, industry representatives, and the NOAA Weather Service prevent strikes by alerting mariners of the presence of large whales to raise awareness and help prevent strikes. The gray whale must get an entire year’s worth of food during those summer months and any disruption could have significant impact on this process. Its color is mottled gray, sometimes with patches that are very pale or white. Habitat modification, such as that resulting from offshore oil and gas development may affect gray whale foraging habitat off Sakhalin Island. In the United States, the Western North Pacific Gray whale population is Federally listed under the ESA (Endangered Species Act) as endangered. Never approach or try to save an injured or entangled animal yourself—it can be dangerous to both the animal and you. Gray whales were the attraction on the world's first ever whale watching trips in the 1950s and today still attract thousands of visitors as they migrate up the west coast of North America each spring. These large whales can grow to about 49 feet long and weigh approximately 90,000 pounds.

The plight of cetaceans is exemplified by the rapid decline of the vaquita in Mexico, a species on the verge of extinction with fewer than 30 individuals remaining. Gray whales are known for their curiosity toward boats and are the focus of whale watching and ecotourism along the west coast of North America. Commercial whaling rapidly brought both Pacific populations to near extinction. Whales are very sensitive to noise and such industrial activities generate massive underwater booms. State Management Plan: None . It can also provide information on the relationship between the eastern and western populations. Admiring whales from a distance is the safest and most responsible way to view them in their natural habitat. Photo: NOAA Fisheries/Merrill Gosho. NOAA Fisheries estimates the population size (also called a stock) for gray whales in its stock assessment reports. Any resulting changes in prey distribution could lead to changes in foraging behavior, nutritional stress, and diminished reproduction for gray whales. Join us to make change. Critically endangered western gray whales migrate into their summer feeding grounds near Sahkalin Island, Russia in late May or early June and return to their winter feeding grounds in the South China Sea in late autumn. Reduce speeds while in the advisory zones or in areas of high seasonal or local whale abundance. The Alaska Fisheries Science Center’s Marine Mammal Laboratory conducts research to provide the scientific advice needed to manage and conserve gray whale populations in Alaska. Newborn calves are approximately 14 to 16 feet long and weigh about 2,000 pounds.

Learn more about the Marine Mammal Health and Stranding Response Program. West Coast, Today, gray whales are protected under the MMPA. From mid-February to May, eastern North Pacific gray whales can be seen migrating northward along the U.S. west coast. H A stock is a group of animals that occupy the same area and interbreed. Our research on the population dynamics, diet and foraging behavior, distribution, and movement patterns of gray whales provides information crucial for understanding and protecting gray whale populations in Alaska. In the late 1990s, the population was as high as 26,000, but today hovers around 22,000. The average and maximum lifespan of gray whales is unknown, although one female was estimated at 75 to 80 years old after death. Collisions with vessels are a major cause of injury and death for whales. Photo-identification studies were conducted from 2002–2017 during the gray whale foraging season off northeastern Sakhalin Island, Russia. Critically endangered western gray whales migrate into their summer feeding grounds near Sahkalin Island, Russia in late May or early June and return to their winter feeding grounds in the South China Sea in late autumn. We recommend that operators of large vessels do the following to help reduce the risk of ship strikes: Learn when the seasonal abundance of large whales is in shipping lanes. Calves are typically born dark gray and lighten as they age to brownish-gray or light gray. The western North Pacific population remains low, and its continued survival is questionable. We strive to reduce the harmful effects of human activities such as fisheries interactions, noise, and pollution, through management actions based on sound science, public input, and public outreach. Analysis of the economic impacts of the state’s whale watching industry, Endangered Species Act (ESA) Section 7(a)(2) Biological Opinion Alaska Liquefied Natural Gas (LNG)…, Each year, NOAA Fisheries collects, verifies, documents, and responds to reports of large whale…, Large whale interaction and entanglement with gear in the ocean poses a major threat to animals…, Distribution and Relative Abundance of Marine Mammals in the Eastern Chukchi Sea, Eastern and…, This report describes field activities of the Aerial Surveys of Arctic Marine Mammals (ASAMM)…, Population assessments are a key component of marine resource management. Gray whales are still hunted by native people of Chukotka, Russia and are subject to catch limits under the International Whaling Commission's aboriginal subsistence whaling scheme. There is an ongoing Unusual Mortality Event for Gray Whale. Keep a sharp look-out for whales; post extra crew on the bow to watch, if possible. The western grey whale population is restricted to the coasts of China, Korea, Japan and Russia and has been hunted almost to extinction; there are estimated to be fewer than 100 animals in this critically endangered population. Responding to dead, injured, or entangled gray whales. The other gray whale in North Atlantic has already been extinct while the Eastern North Pacific one has recovered from the very low levels. Gray whales become sexually mature between 6 and 12 years, with the average of maturity being about 8 to 9 years old. Report a sick, injured, entangled, stranded, or dead animal to make sure professional responders and scientists know about it and can take appropriate action. Additionally, changing water temperature and currents could impact the timing of environmental cues important for navigation and migration. Accidental entanglement in fishing nets has proved to be a serious threat, killing several gray whales off the coasts of Asia. Photo: NOAA Fisheries. The eastern North Pacific stock was once listed as endangered under the Endangered Species Act but was delisted in 1994 based on evidence that the population had nearly recovered to its estimated original population size and was not in danger of extinction throughout all or a significant portion of its range. In 1999, NOAA Fisheries conducted, a review of the status of the eastern North Pacific stock of gray whales. Consult the Local Notice to Mariners or Coast Pilot for more information. However, the western population is currently listed as endangered in the ESA, with around 200-300 individuals remaining today. Speak up for species and places through WWF's Action Center. Females are slightly larger than males. Keep your distance. To understand the health of marine mammal populations, scientists study unusual mortality events. The western population remains very low in number, and is listed as endangered under the ESA and depleted under the Marine Mammal Protection Act. Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that may also have implications for human health and welfare. estimated 150 individuals (western population); stable (eastern population), View our inclusive approach to conservation, Trump Administration to roll back crucial Arctic protections. Gray whales were the attraction on the world's first ever whale watching trips in the 1950s and today still attract thousands of visitors as they migrate up the west coast of North America each spring. Federal Status: None (delisted from Endangered in 1994) Recovery Plans: None . For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. A gray whale off the coast of Alaska. based on photo-identification data collected off Sakhalin Island and southeastern Kamchatka, Russia. Make a symbolic whale adoption to help save some of the world's most endangered animals from extinction and support WWF's conservation efforts. Gray whales earned the nickname “devil fish” because of their aggressive reactions when harpooned. NOAA Fisheries’ West Coast Region encourages the public to be “whale wise” and has also published its own safe viewing guidelines and outreach materials for boaters, paddlers, and drone operators on the west coast. Our work strives to protect gray whales by: Reducing interactions with commercial and recreational fishing gear. Numerous organizations around the country are trained and ready to respond. Lacking a dorsal fin, they instead have a dorsal hump about two-thirds of the way back on the body, and a series of 6 to 12 small bumps, called “knuckles”, between the dorsal hump and the tail flukes. NOAA Fisheries Southwest Fisheries Science Center conducts regular surveys of eastern North Pacific gray whale abundance and calf production. The calm, warm waters of the lagoon are a safe place for young whales, free from predators like killer whales. Although the gray whale is no longer considered endangered, there are still threats to gray whale populations . Like all marine mammals, gray whales are protected under the Marine Mammal Protection Act. Overall, Gray whale numbers are stable currently, western population is listed as Critically Endangered (CR), while eastern population is Least Concern (LC). Noise pollution can threaten whale populations, interrupting their normal behavior and driving them away from areas important to their survival. Although western and eastern stocks of gray whales thought to be relatively isolated from each other, recent satellite tagging data and photo-identification and genetic matches have shown that at least some western North Pacific stock gray whales migrate across the northern Gulf of Alaska, and along the west coast of British Columbia, the United States, and Mexico. Historically, widely ranging along the Asian coast, contemporary WGW aggregations are known primarily from summer feeding grounds off Sakhalin Island (SI), Russia [ 4 ]. Donations are tax-deductible as allowed by law. In October 2013, the energy company announced that they would postpone construction for five years.Further south, in the Gulf of California, WWF supports a research team that is monitoring the population size and health of the gray whales that return each winter. Gray whales are vulnerable to vessel strikes because they feed and migrate along the U.S. west coast, which has some of the world’s heaviest vessel traffic associated with some of the largest ports in the country. This allowed the population to recover, and it was removed from the Endangered Species list in 1994. At one time there were three gray whale populations: a north Atlantic population, now extinct; a Korean or western Pacific stock now very depleted; and the eastern Pacific population, the largest surviving population. The western North Pacific stock of gray whales has not recovered. A conservation achievement that resulted in the recovery of the California gray whale population from near extinction. International conservation measures were enacted in the 1930s and 1940s to protect whales from over exploitation and in the mid-1980s the International Whaling Commission instituted a moratorium on commercial whaling. Gray whales make one of the longest annual migrations of any mammal, traveling about 10,000 miles round-trip. Our scientists collect and present these data in annual stock assessment reports. Calves are born during migration or in the shallow lagoons and bays of Mexico from early January to mid-February. To understand the health of marine mammal populations, scientists study unusual mortality events. Gray whales are at high risk of becoming entangled in fishing gear. In the north … Oil and gas development, entanglement in fishing gear, and collisions with ships threaten gray whales. The … Once validated, this approach will enable aerial identifications to be linked to longer-term oblique-view photo-identification catalogs to more precisely quantify calving intervals and relate photogrammetry measurements to population identity and life history parameters. There are two geographic distributions of gray whales in the North Pacific: the eastern North Pacific stock, found along the west coast of North America, and the western North Pacific stock, found along the coast of eastern Asia. Like all species of great whales, the gray whale was in danger of extinction until it became protected by law in the 1970s. They have barnacles and whale lice on their bodies, with higher concentrations found on the head and tail. Ocean noise, It is listed as endangered under the ESA and depleted under the MMPA. North Atlantic populations were extirpated (perhaps by whaling) on the European coast before 500 AD and on the American coast around the late 17th to early 18th centuries. Collisions between whales and large vessels often go unnoticed and unreported, even though whales can be injured or killed, and vessels can sustain damage. For example, NOAA Fisheries has collaborated with NOAA Sanctuaries and the U.S. Coast Guard to effect changes in shipping lanes that should help reduce the risk of vessels striking large whales. Most of the eastern North Pacific stock gray whales spend the summer feeding in the northern Bering and Chukchi Seas, but some feed along the Pacific coast during the summer, in waters off of Southeast Alaska, British Columbia, Washington, Oregon, and northern California. The common name of the whale comes from the gray patches and white mottling on its dark skin. This ban was the first international agreement to protect a whale species from commercial whaling operations. The eastern Pacific population of gray whales was removed from the endangered species list in 1995, but the western Pacific (Korean) population, which has not recovered at all, remains listed. No reasonable doubt that the last individual has died, Known only to survive in cultivation, in captivity or as a naturalised population, Facing an extremely high risk of extinction in the Wild, Facing a high risk of extinction in the Wild, Likely to qualify for a threatened category in the near future, Does not qualify for Critically Endangered, Endangered, Vulnerable, or Near Threatened. The western North Pacific gray whale is on the verge of extinction because of such threats. Once common throughout the Northern Hemisphere, gray whales are now only found in the North Pacific Ocean where there are two extant populations, one in the eastern and one in the western North Pacific. The western North Pacific population is listed as endangered under the Endangered Species Act and depleted under the MMPA. Gray whales were the attraction on the world's first ever whale watching trips in the 1950s and today still attract thousands of visitors as they migrate up the west coast of North America each spring. NOAA Fisheries supports responsible viewing of marine mammals in the wild and has adopted a guideline to observe all large whales from a safe distance of at least 100 yards by sea or land. Our work includes: Passive acoustic monitoring of whale presence and ambient noise levels. Gray whales have a mottled gray body with small eyes located just above the corners of the mouth. NOAA Fisheries is investigating all aspects of acoustic communication and hearing in marine animals, as well as the effects of sound on whale behavior and hearing. and displace them from areas important to their survival. Be responsible when viewing marine life in the wild. Around 1950, governments worldwide declared the gray whale as an endangered species and banned whaling themBecause of illegal whale hunting. NOAA Fisheries’ West Coast Regional Office and Marine Mammal Laboratory fund photo-identification studies to better understand gray whale stock structure, distribution and abundance. Gray whales are amazing long-distance travellers, undertaking migrations of thousands of kilometres each year. NOAA Fisheries conducts research on the biology, behavior, and ecology of the gray whale. The western North Pacific stock of gray whales has not recovered. Habitat impacts, Ecological niche. Each winter, gray whales migrate to calving lagoons in Baja California to breed and bear their young. , an unusual mortality event is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response.". When stranded animals are found alive, NOAA Fisheries and our partners assess the animal’s health. The impacts of climate change on baleen whales are unknown, but it is considered one of the largest threats facing high latitude regions where many gray whales forage. Disturbance from whale watching activities, All gray whales are mottled with lighter patches. Determining the size of gray whale populations helps resource managers gauge the success of NOAA Fisheries’ conservation measures. The eastern North Pacific population was once listed as endangered under the ESA but has successfully recovered and was delisted in 1994. The team takes photos to identify individuals, collects tissue samples and records their underwater communication.Other activities include:• pushing for stricter environmental standards for offshore oil and gas projects• engaging a local energy company regarding their operations• running a public campaign to raise awareness regarding the threats posed by the Sakhalin offshore oil and gas projects. Keep speeds to 10 knots or less to reduce potential for injury. The cause of the population decline is thought to be overhunting. Like other baleen whales, long-term bonds between individuals are thought to be rare. The gray whale is one of the animal kingdom's great migrators. Shallow coastal waters of eastern North Pacific, Bering and Chukchi Seas. The status of the western Pacific population is relatively unknown, but it is believed to … Gray whales suck sediment and food from the sea floor by rolling on their sides and swimming slowly along, filtering their food through 130 to 180 coarse baleen plates on each side of their upper jaw. Today, gray whales are protected under the MMPA. We helped restrict seismic surveys that were shown to displace gray whales from their feeding ground and continue to urge the Russian government to establish a gray whale sanctuary off Sakhalin Island. Evaluating risk from these activities requires fine-scale data on precise migration routes. Gray Whale Videos . They are also highly vulnerable to human activities in the ocean. This hotline is available 24 hours a day, 7 days a week for anyone in the United States. Whales are at the top of the food chain and have an important role in the overall health of the marine environment. Underwater noise can reduce the ability of whales to communicate with each other, increase their stress levels, interrupt their normal behavior and displace them from areas important to their survival. Gray whales are found mainly in shallow coastal waters in the North Pacific Ocean. With the whales on the edge of extinction any disruption of normal feeding patterns is of concern. Stop immediately if within 100 yards. The gray whale is about 17 feet long at birth and reaches a maximum size of approximately 45 feet; females are larger than males. The western gray whale population is endangered with approximately 175 individuals and 33 known reproductive females. Their pectoral flippers are broad, paddle-shaped, and pointed at the tips. Pair of gray whales sighted approximately 10 km northeast of Wainwright, Alaska. Western gray whales (WGWs), once thought to be extinct, currently number approximately 130 individuals and are listed as critically endangered by the International Union for Conservation of Nature . We continue to monitor the abundance and calf production of the stock, especially in light of recent climatic changes occuring in their arctic feeding grounds. UAS photographs are also being evaluated for matching individual whales from aerial and shore-based photo-identifications based on their natural markings. Shore-based observers have conducted systematic counts of eastern North Pacific gray whales migrating south along the central California coast in most years since 1967. The data time series for abundance estimation extends from 1967 to 2020 and most recently has integrated use of fixed-wing UAS platforms and infrared cameras to aid visual observers. The Alaska Region has also created Marine Mammal Viewing Guidelines for reducing disturbance while watching whales, sea lions, seals, dolphins, and porpoise from boats, planes and helicopters. In 1936 Gray Whales were protected from commerical hunting. Vessel strikes, WWF works to ensure they can live and thrive in their natural habitat. NOAA Fisheries Southwest Fisheries Science Center conducts regular surveys of eastern North Pacific gray whale abundance and calf production. Gray whales have a hump and a ridge of sharp bumps along their backs, instead of a dorsal fin. Slowly distance your vessel from the whale. These assessments allow us to evaluate and report the status of managed fisheries, marine mammals, and endangered/threatened species under the authorities of the Magnuson-Stevens…. They are primarily bottom feeders that consume a wide range of benthic (sea floor) and epibenthic (above the sea floor) invertebrates, such as amphipods. These baleen whales currently live around Japan and China. GRAY WHALE (Eschrichtius robustus)RANGE. Collisions with all sizes and types of vessels are one of the primary threats to marine mammals, particularly large whales. Washington, DC 20037. The gray whale is the only member of the Eschrichtiidae family, and the oldest of the baleen whales. Noise pollution can threaten whale populations, interrupting their normal behavior and driving them away from areas important to their survival. There were many threats to the gray whales.
