Humpback whales can become entangled by many different gear types including moorings, traps, pots, or gillnets. Indian Ocean humpback dolphin (Sousa plum… Under the MMPA, the Atlantic Large Whale Take Reduction Plan and Pacific Offshore Cetacean Take Reduction Plan address the threat of fishery entanglements. Southeast, 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. In 1970, the humpback whale was listed as endangered under the Endangered Species Conservation Act, the predecessor of the Endangered Species Act (ESA). In Hawaii, regulations also prohibit operating an aircraft within 333 yards of a humpback whale. Males also sing complex songs for hours that can be heard 20 miles away—the low-frequency portions of the song are audible much farther in deep water. The Hawaii population, which breeds in the main Hawaiian Islands and feeds in most of the known feeding grounds in the North Pacific, particularly Southeast Alaska and northern British Columbia. The Mexican population, which breeds along the Pacific coast of Mexico and the Revillagigedo Islands, transits the Baja California Peninsula, and feeds across a broad range from California to the Aleutian Islands (Alaska). The humpback whale (Megaptera novaeangliae) has moved from Vulnerable to Least Concern, meaning it is at low risk of extinction, although two subpopulations are Endangered.The southern right whale (Eubalaena australis) has also moved to Least Concern.“Humpbacks and southern right whales are making a comeback in much of their range mainly because they have been protected … Whale sharks can live up to 100 years in the wild and are currently listed as endangered by the International Union for the Conservation of Nature. Humpback whales feed on krill (small shrimp-like crustaceans) and small fishes by straining huge volumes of ocean water through their baleen plates. Pacific Islands, West Coast, Humpback whales (Megaptera novaeangliae) were hunted commercially in Canada's Pacific region until 1966. Of the 14 distinct populations, 12 are estimated to number more than 2,000 humpback whales each and two are estimated to number fewer than 2,000. The Center for Biological Diversity is a national, nonprofit conservation organization with more than 1.6 million members and online activists dedicated to the protection of endangered species and wild places. NOAA Fisheries scientists have spent several years researching this question, and their answer is not a simple yes or no. Limit vessel speed in certain areas to reduce the likelihood of deaths and serious injuries from vessel strikes. National Marine Fisheries Service (NMFS) issues a rule prohibiting approaching within 100 yards of a humpback whale in Alaska (PDF 65 kB) 2009 Given the change in listing status of humpback whales in 2016, we are currently evaluating recovery plan needs for the currently listed DPSs. Around 900 humpbacks spend spring and summer in the rich feeding grounds of Stellwagen Bank before they head south in the late fall to mate and give birth in the warmer waters of the Dominican Republic. The United States listed all humpback whales as endangered under the Endangered Species Conservation Act in 1970, and then under the Endangered Species Act in 1973. At least four humpback whale populations occur in the North Pacific: Seven populations of humpback whales are found in the Southern Hemisphere, all of which feed in Antarctic waters. In order, with the most endangered first, and their IUCN status listed: 1. While calving, they prefer shallow, warm waters commonly near offshore reef systems or shores. Learn more about our marine life viewing guidelines >. In the Pacific, we implemented the Pacific Offshore Cetacean Take Reduction Plan to reduce mortalities and serious injuries of several marine mammal stocks, including humpback whales, incidentally injured in the California thresher shark/swordfish drift gillnet fishery. North Atlantic right whale (Eubalaena glacialis)EN 4. Four of these are considered endangered, while … There are several areas where U.S.-managed stocks of humpback whales are the center of whale watching industries, including: The Gulf of Maine (particularly within the Stellwagen Bank National Marine Sanctuary), the southeastern U.S. and West Indies, California, Alaska (particularly southeast Alaska), and the Hawaiian Islands. This hotline is available 24 hours a day, 7 days a week for anyone in the United States. Humpback whales were first classified as in need of protection under the Endangered Species Act in 1970. Keep your distance. Some populations swim 5,000 miles from tropical breeding grounds to colder, productive feeding grounds. Humpback whale flukes can be up to 18 feet wide—they are serrated along the trailing edge, and pointed at the tips. The Mexico population is listed as threatened. One reason for this is the improved management of whaling that began in the mid-1970s, when management by population or stock was introduced. Developing methods to reduce vessel strikes. Humpback whales Are humpback whales still endangered, or have their populations recovered enough since whaling ended that they can now be taken off the Endangered Species List? The species is increasing in abundance in much of its range, but faces threats from entanglement in fishing gear, vessel strikes, vessel-based harassment, underwater noise, and habitat impacts. When an entangled whale is reported, responders can be authorized to evaluate the entanglement and, in cases where the entanglement is life threatening to the animal and a response can be carried out safely, a team may attempt to cut the whale free from gear. When photographed, scientists can catalog individuals and track them over time, a process called photo-identification. Other research is focused on the acoustic environment of cetaceans, including humpback whales. Throughout its range, the humpback whale has been listed as endangered under the Endangered Species Conservation Act of 1970, and as depleted under the Marine Mammal Protection Act of 1972. Humpback whales’ bodies are primarily black, but individuals have different amounts of white on their pectoral fins, their bellies, and the undersides of their flukes (tails). These two populations migrate south during the winter to calve and mate in the West Indies and Cape Verde (off the coast of Africa), and possibly in other areas. NOAA Fisheries and the Dominican Republic’s Ministry of Environment and Natural Resources have established the world’s first sister sanctuaries to protect humpback whales. Humpback whales reach sexual maturity between the ages of 4 and 10 years. The humpback whale takes its common name from the distinctive hump on its back. The NOAA’s proposal would remove … Photo: NOAA Fisheries. During the summer months, humpback whales spend most of their time feeding and building up fat stores (blubber) to sustain them throughout the winter.

The Years of the North Atlantic Humpback Project in 1992 to 1993 and the follow-up project, More North Atlantic Humpbacks, in 2003 to 2005 were international collaborations to monitor humpback whale populations, investigate human-caused deaths, and conduct various other surveys, including research on humpback songs, across many humpback habitats. Tracks the implementation of recovery actions from Endangered Species Act (ESA) recovery plans. Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that can have implications for human health and welfare. The Stellwagen Bank National Marine Sanctuary, off the coast of Massachusetts, and the Santuario de Mamíferos Marinos de la República Dominicana are two marine protected areas 3,000 miles apart. The sister sanctuary agreement strengthens coordination and management efforts between the two sanctuaries and improves humpback whale recovery in the North Atlantic.

The original listing of humpback whales predated the statutory requirement under the ESA to designate critical habitat. However, impacts from humans continue to impede the recovery of … It is also illegal to approach humpback whales in Hawaii within 333 yards by air. The species got its name as the “right” whale to hunt: these animals swim slowly close to shore and are so blubber-rich they float when dead. When stranded animals are found alive, NOAA Fisheries and its partners assess the animal’s health and try to return it to the water. Commission on Environmental Cooperation Humpback Whale Conservation Action Plan for the U.S., Canada, and Mexico. They are distinctive enough to be used as “fingerprints” to identify individuals. Read the recovery plan for the humpback whale. Humpback whales are vulnerable to vessel strikes throughout their range, but the risk is much higher in some coastal areas with heavy ship traffic. By 18th century, the commercial value of humpback whales increased and that made them a preferred target for hunters. You may also contact your closest NOAA Office of Law Enforcement field office during regular business hours. The California Department of Fish and Wildlife has again delayed the start of commercial Dungeness crab season south of Mendocino County until at least Dec. 16 to prevent endangered whales … Endangered Pacific humpback whales are getting protection. Understanding and addressing the effects of ocean noise. COSEWIC’s assessment of the North Pacific population of humpback whales is as follows: Although this recovering population is no longer considered to be Threatened, it is not yet secure. Its long pectoral fins inspired its scientific name, Megaptera, which means “big-winged.” Humpback whales are a favorite of whale watchers―they are often active at the water surface, for example, jumping out of the water and slapping the surface with their pectoral fins or tails. All humpback whales are protected under the MMPA and three stocks are listed as depleted (i.e., they have fallen below their optimum sustainable population levels). To understand the health of marine mammal populations, scientists study unusual mortality events. They travel great distances during their seasonal migration with some animals migrating 5,000 miles between high-latitude summer feeding grounds and winter mating and calving areas in tropical waters. It is well known that overexploitation by the whaling industry led to serious declines in many of the world’s populations of whales, although thankfully no species was brought to extinction and many are now in the process of recovering, although not all. Vaquita porpoise (Phocoena sinus)CR 2. We conducted an 8-year photo-identification study to monitor humpback whale … NMFS distributed draft Recovery Plan for the Humpback Whale (PDF 116 kB) 1991. NOAA Fisheries worked worldwide to identify and apply protections for humpback whales. Humpback whales probably live about 80 to 90 years. (. In 2011, the humpback whale was downlisted from Threatened to Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). 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.

When the ESA was passed in 1973, the humpback whale was listed as endangered throughout its range. Most populations of humpback whales no longer need endangered species protections, according to a decision by the National Marine Fisheries Service. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. Currently, four out of the 14 distinct population segments are still protected as endangered, and one is listed as threatened (81 FR 62259, September 2016). Both Alaska and Hawaii have specific guidance and requirements for minimizing whale watching impacts on humpback whales. In the same year, it was designated as "depleted" under the Marine Mammal Protection Act (MMPA). 1990. The major actions recommended in the plan are: Reduce or eliminate injury and mortality caused by fisheries and fishing gear and by vessel collisions. Educate naturalists, captains, and passengers to have “SENSE” while watching whales. Listed as endangered by the State of Alaska. When the ESA was passed in 1973, the humpback whale was listed as endangered wherever found. Information from these research projects can be used to inform management actions that protect the humpback whale and reduce their human-related mortalities. Internet Explorer lacks support for the features of this website. Stay at least 100 yards away. Females produce a single calf, on average every 2 to 3 years, although annual calving has been documented in some individuals. Collisions with vessels are a major cause of injury and death for whales. The U.S. FWS's Threatened & Endangered Species System track information about listed species in the United States. Commercial whaling severely reduced humpback whale numbers from historical levels. Entanglement in fishing gear is a leading cause of serious injury and death for many whale species, including humpback whales. Humpback whales carry unique white patterns on the undersides of their tail flukes (the rear flippers) just like human fingerprints. Photo: NOAA Northeast Fisheries Science Center/Christin Khan. This research involves increasing our understanding of the basic acoustic behavior of whales, dolphins, and fish; mapping the acoustic environment; and developing better methods to locate cetaceans using autonomous gliders and passive acoustic arrays. Vessel-based harassment, Alaska, Humpback whales are found in every ocean in the world. Three humpback whale stocks in U.S. waters are designated as depleted under the Marine Mammal Protection Act (as of the 2016 stock assessment reports). Many Southern Hemisphere humpback whales have extensive amounts of white on their flanks and bellies. Collect as much data as possible from dead whales through our Health and Stranding Program. New England/Mid-Atlantic, Threats to these whales include entanglement in fishing gear, ship strikes, whale … The ultimate goal of the Humpback Whale Recovery Plan is to help humpback whales thrive, allowing every population to be reclassified from “endangered” to “threatened,” and ultimately removed from the ESA's list of threatened and endangered species. Commercial whaling severely reduced humpback whale numbers from historical levels. NOAA Fisheries conducted a global status review of humpback whales. Learn more about marine mammal stock assessments, Find humpback whale stock assessment reports. Collaborating with international scientists to track the movements and behavior of humpback whales as they migrate across international boundaries. There is also evidence for the existence of a fifth breeding area in the western North Pacific. NOAA Fisheries co-manages the sanctuary with the State of Hawaii, conducts research on humpback whales, and operates a sanctuary education and learning center. Broad habitat areas and long migrations make it difficult to estimate population size. While calves are not believed to maintain long-term associations with their mothers, they are more likely to be found in the same regions of the feeding and breeding grounds as their mothers. Once the fish are corralled and pushed toward the surface, the whales lunge upward through the bubble net with open mouths engulfing their prey. Instead, I heard and felt it. Here are some tips to avoid collisions: Keep a sharp lookout. Some populations (such as those off eastern and western Australia) are believed to number in excess of 20,000 animals—a remarkable recovery given that the same populations were almost eradicated by whaling almost sixty years ago. Whale watching vessels, recreational boats, and other vessels may cause stress and behavioral changes in humpback whales. Franciscana (Pontoporia blainvillei)VU 9. In the North Atlantic, two populations of humpback whales feed during spring, summer, and fall throughout a range that extends across the Atlantic Ocean from the Gulf of Maine to Norway. ESA Species Directory (searchable) Section 7 Consultations in Alaska. After an 11 month gestation, calves are born 13 to 16 feet in length. South Asian River dolphin (Platanista gangetica)EN 5. Stop immediately if within 100 yards. Once entangled, if they are able to move the gear, the whale may drag and swim with attached gear for long distances, ultimately resulting in fatigue, compromised feeding ability, or severe injury, which may lead to reduced reproductive success and death. Learn who you should contact when you encounter a stranded or injured marine animal >. NOAA Fisheries conducts research on the biology, behavior, and ecology of the humpback whale. We also work with our partners to ensure that regulations and management plans are in place to reduce entanglement in fishing gear, create safer shipping lanes, and protect habitats. Collisions between whales and large vessels can injure or kill whales, damage the vessels, and injure passengers, but they often go unnoticed and unreported. Scientists use small aircraft to spot large whales (including humpbacks) and record their seasonal distribution. This led to the development of the … The late-19th-century introduction of the explosive harpoon allowed whalers to accelerate their take. The Central American population, which breeds along the Pacific coast of Central America, including off Costa Rica, Panama, Guatemala, El Salvador, Honduras, and Nicaragua, and feeds off the West Coast of the United States and southern British Columbia. Watch your speed in areas of known marine mammal occurrence. Scientists have revealed the return of critically endangered Antarctic blue whales to the sub-Antarctic island of South Georgia, 50 years after whaling all but wiped them out. Humpback whales were hunted as early as the 18th century. Under these regulations it is unlawful for a person subject to…, NOAA Fisheries has issued an incidental harassment authorization (IHA) to Ørsted Wind Power North America, LLC, (Ørsted) to incidentally harass, by Level B harassment only, marine mammals during marine site characterization surveys in coastal waters…, NOAA Fisheries has issued an incidental harassment authorization (IHA) to the Lamont-Doherty Earth Observatory of Columbia University (L-DEO) to incidentally harass marine mammals during a marine geophysical survey in the Aleutian Islands, Alaska. Underwater noise can pose a threat to whales, interrupting their normal behavior and potentially causing temporary or permanent reductions in hearing. There is evidence to suggest that most humpback whales experience entanglement over the course of their lives, but are often able to shed the gear on their own. Five humpback populations are still struggling however, and will retain their current statuses. Megaptera novaeangliae. ) Fish and Wildlife Service … Studying humpback whale population structure. Our work includes: Monitoring humpback whale abundance and mortality in U.S. waters. Slowly distance your vessel from the whale. The results are used to inform management decisions and enhance recovery efforts for this species. Continue the international moratorium on commercial whaling. The ESA requires that after a species is removed from the list of threatened and endangered species because it has recovered, we monitor the status of that species for a minimum of five years.
