2025年1月10日 · The North Atlantic right whale is one of three right whale species, along with the North Pacific right whale and the southern right whale. Today, there are likely fewer than 500 right whales in the entire North Pacific, and approximately 30 individuals in the eastern North Pacific stock inhabiting U.S. waters, while southern right whale ...

2023年4月24日 · For the North Atlantic right whale to recover, NOAA determined that less than one whale per year can be seriously injured or killed. Data shows that North Atlantic right whale mortalities from fishing entanglement continue to occur at levels five times higher than the species can withstand. Furthermore, unless sub-lethal trauma from ...

2004年11月3日 · A critical factor in the North Atlantic right whale’s population decline is human-induced mortality, caused by collisions with ships and by entanglement in fishing gear. Unlike the recovering Southern Ocean right whale population, which travel in far less populated and trafficked waters, North Atlantic right whales are exposed to gauntlets.

North Atlantic right whales, as well as other endangered baleen whales. The first day was open to the public, with a series of presentations by scientists that reviewed current tagging technologies and their uses on northern and southern right whales and other baleen whales.

2013年7月16日 · The National Marine Fisheries Service (NMFS) has implemented many regulations since the late 1990s as part of an Atlantic Large Whale Take Reduction Plan to reduce entanglement-related deaths of right whales. Most of those deaths are caused by lines associated with lobster traps and gillnets. To date, there is no evidence demonstrating that those …

pot/trap lines co-occur with right whales, as they do in the Gulf of Maine, there is a risk of entanglement, and Maine lobster gear could be responsible for some right whale entanglements. Over 85 percent of all North Atlantic right whales show evidence of past entanglements, and on average, 15 to 26 percent experience at least one entanglement

2023年7月6日 · A North Atlantic right whale and cargo ship (Florida Fish and Wildlife Conservation Commission). After Canada implemented routing measures in the Bay of Fundy in 2003, NOAA and the U.S. Coast Guard implemented recommended routing for vessels traveling through important right whale habitats in Cape Cod Bay and near ports in Georgia and Florida ...

2024年5月10日 · Saving the North Atlantic right whale from extinction has never been easy, but it now may be getting even more difficult due to the depletion of a key food source in the Gulf of Maine. Until the last 20 years, the Gulf’s cool waters and nutrient-rich currents supported a dense reservoir of the whale’s primary prey—a tiny, energy-rich ...

Since 1970, nearly half of all documented North Atlantic right whale deaths have been due to two human-related causes—ship strikes and entanglements in fishing gear. Ship strikes were the major known cause of death before the mid-2000s. After management measures were implemented between 2006 and 2008 to reduce ship strikes, deaths due to this cause […]

Coastal North Atlantic right whale (Eubalaena glacialis) habitat in the western North Atlantic ranges from the southeastern US coast for calving, to New England and Canada for feeding, although whether there is a specific site for major breeding activity is unclear (Winn et al., 1986). The estimated population size has remained at 300-350 for
