In the Recovery Strategy, each of the four recovery objectives is accompanied by a series of strategies to help achieve the objectives.

2014. Mitigation of potential impacts, monitoring and documentation of tourism impacts, and education and training of tour operators can all help reduce the potential impacts of tourism.The future level of tourism likely to occur in the Gully MPA and other high-use areas is unknown, and it is important to develop thresholds limiting the type and number of vessels conducting whale-watching activities within an area during a given time period early on.

They reportedly took 56,389 whales between 1882 and the late 1920s, primarily east of Greenland, although the early whaling records are not always reliable or available (Whitehead & Hooker 2012).Whaling records from all areas also do not generally report struck but lost animals, so removal numbers could be higher. Studies should also be conducted to determine the impact of anthropogenic noise on the features and attributes of the identified Northern Bottlenose Whale critical habitat, and on the whales’ ability to use this habitat to carry out their life functions.
For the critical habitat located in Shortland and Haldimand canyons, it is anticipated that legal protection will be accomplished through a SARA Critical Habitat Order made under subsections 58(4) and (5), which will invoke the prohibition in subsection 58(1) against the destruction of the identified critical habitat.Although the Northern Bottlenose Whale Recovery Strategy identifies activities that may cause destruction of critical habitat, thresholds to avoid the destruction of critical habitat for various activities have yet to be defined (DFO 2016a). 1993, NAMMCO 2019). Current conservation concerns include threats from human activities such as disturbance related to offshore oil and gas developments and naval sonar, as well as entanglement, pollution, ingest… Canadian Technical Report of Fisheries and Aquatic Sciences 3114: vi + 251 pp.King, S.L., R.S.

(2009). Part of the recovery goal for the Scotian Shelf Northern Bottlenose Whale population is to maintain a stable or increasing population size, and updating population estimates will contribute directly to monitoring the recovery of the population.The most up-to-date Scotian Shelf population estimate, based on an analysis of data from 1988-2011, is 143 individuals, with 95% confidence that the real population number is between 129 and 156 individuals (O’Brien and Whitehead 2013).
Northern Bottlenose Whales, like other beaked whales, are thought to be particularly sensitive to noise.

Most easily recognised by their large foreheads, they have bulbous melons which are particularly pronounced in older males.Sporting rich chocolate, olive brown and grey tones on their bodies, their heads become lighter in shade whilst their crescent-shaped dorsal fins are darker. 2009.
Whaling data suggest that females give birth to single offspring about every two years after a gestation of about 12 months (Benjaminsen and Christensen 1979), although observations of calves in the Scotian Shelf population suggest that the reproductive rate is lower than this: in the Gully between 1988 and 1999, only 6% of 3,113 sightings of Northern Bottlenose Whales close enough to the research vessel to be photoidentified (<~100m) were recorded as first-year calves (H. Whitehead, unpublished data). 2015). All Canadians are invited to join in supporting and implementing this action plan for the benefit of the Northern Bottlenose Whale, Scotian Shelf population and Canadian society as a whole.Under SARA, an Action Plan provides the detailed recovery planning that supports the strategic direction set out in the Recovery Strategy for the species. NORTHERN BOTTLENOSE WHALES AND THE GULLY MARINE PROTECTED AREA Endangered Endangered northern bottlenose whales in Canada are mostly found in the Gully Marine Protected Area, an astoundingly rich underwater canyon located 200km off the coast of Nova Scotia. It is not clear what the direct effects of the sounds are, but the deep-diving behaviour of northern bottlenose whales may make them especially vulnerable to physiological impacts from acoustic disturbance (DFO 2017).In one field experiment near Jan Mayen Island, northern bottlenose whales were exposed to naval sonar. Ellis, and J.K.B.
Northern bottlenose whales have occasionally been seen in both the Mediterranean and Baltic Seas, and have been observed off the Azores and as far south as the Cape Verde Islands (Taylor et al.
