Assessment rationale/justification
The species is widely distributed in eastern Canadian marine waters. Surveys of portions of the range (Bay of Fundy/Gulf of Maine and the Gulf of St. Lawrence) during the late 1990s indicated more than 100,000 porpoises. Incidental catch (bycatch) in fishing gear, especially gillnets, is a major source of mortality. Bycatch probably has declined in areas where use of gillnets has decreased. Management measures in the Bay of Fundy and Gulf of Maine have been shown to reduce porpoise bycatch rates in gillnets. However, these measures have not been implemented in much of the species' range, including the Gulf of St. Lawrence and Newfoundland and Labrador, where annual mortality in several gillnet fisheries is still estimated to be in the thousands. There is also some concern that porpoises in the Bay of Fundy and possibly other areas may be excluded from portions of their habitat by acoustic harassment devices associated with aquaculture. Although the population remains abundant, the particular susceptibility of harbour porpoises to bycatch in fishing gear represents an incipient threat. Given that, the lack of good abundance information in some parts of the range and the lack of porpoise bycatch monitoring and mitigation in many of the relevant fisheries are reasons for concern.; L'espèce est largement répandue dans les eaux marines de l'est du Canada. Les dénombrements dans des parties de l'aire de répartition (baie de Fundy, golfe du Maine et golfe du Saint-Laurent) à la fin des années 1990 indiquaient plus de 100 000 marsouins. Les prises accessoires dans les engins de pêche, particulièrement dans les filets maillants, sont une cause majeure de mortalité. Ces prises ont probablement diminué dans les endroits o๠l'utilisation de filets maillants a diminué. Des mesures de gestion dans la baie de Fundy et le golfe du Maine ont permis de réduire le taux de prises accessoires de marsouins dans les filets maillants. Cependant, ces mesures n'ont pas été mises en ?œuvre dans la majeure partie de l'aire de répartition de l'espèce, incluant le golfe du Saint-Laurent et Terre-Neuve-et-Labrador, o๠les mortalités annuelles dans plusieurs pêches au filet maillant sont encore estimées dans les milliers. Il y a également certaines préoccupations quant au fait que les marsouins dans la baie de Fundy et possiblement dans d'autres aires peuvent être tenus à l'écart de certaines parties de leur habitat en raison de l'utilisation d'appareils de harcèlement acoustique associés à l'aquaculture. Bien que la population demeure abondante, la sensibilité particulière du marsouin commun à la prise accessoire dans les engins de pêche représente une menace croissante. Par conséquent, le manque de bonne information sur l'abondance dans certaines parties de l'aire de répartition et le manque de surveillance et d'atténuation des prises accessoires de marsouins dans un grand nombre de pêches pertinentes justifient la préoccupation.

Assessment rationale/justification
Currently sighted only infrequently on former whaling grounds off British Columbia. Coastal whaling took at least 7,600 animals from the population between 1905 and 1967, and thousands of additional animals were taken by pelagic whalers through the 1970s. Catch rates from coastal whaling stations declined precipitously off British Columbia in the 1960s. Based on the severe depletion and lack of sufficient time for recovery, it is inferred that present population is below 50% of its level, 60-90 years ago. Individuals continue to be at risk from ship strikes and entanglement in fishing gear.; L'espèce est actuellement observée seulement de façon peu fréquente dans les anciens lieux de pêche à la baleine au large de la Colombie-Britannique. La pêche cà´tière à la baleine a réduit la population entre 1905 et 1967 d'au moins 7 600 individus, et des milliers d'autres individus ont été pris lors de pêches pélagiques durant les années 1970. Le taux des prises des stations de pêche cà´tière à la baleine a diminué de façon abrupte au large de la Colombie-Britannique au cours des années 1960. En se basant sur l'importante diminution de la population et un délai de temps insuffisant pour son rétablissement, on en a déduit que la population actuelle est inférieure à 50 % de son niveau d'il y a 60 à 90 ans. Les individus continuent d'être vulnérables aux collisions avec des navires et à l'enchevêtrement dans des engins de pêche.

Assessment rationale/justification
The size of this population was reduced by whaling during much of the 20th Century. However, sightings remain relatively common off Atlantic Canada and they have not been hunted since 1971. The current abundance and level of depletion compared with pre-whaling numbers are uncertain. The whales face a number of current threats including ship strikes and entanglement in fishing gear, but none is believed to seriously threaten the population.; La pêche à la baleine a réduit la taille de cette population pendant une grande partie du XXe siècle. Cependant, l'espèce est aperçue de façon relativement fréquente au large du Canada atlantique et n'est pas chassée depuis 1971. Son abondance et son niveau d'appauvrissement actuels comparativement aux niveaux qui existaient avant le début de la pêche à la baleine sont incertains. Les rorquals sont confrontés à un certain nombre de menaces, dont les collisions avec des navires et l'enchevêtrement dans des engins de pêche, mais aucune de ces dernières ne semblent menacer gravement la population.

Assessment rationale/justification
The population numbered at least 11,000 animals when commercial whaling began. Whaling reduced the population to less than 30% of its former abundance. Recent estimates indicate that the population is growing and is larger than previously thought, but is likely to still number fewer than 3,000 individuals of all ages. The population qualifies for endangered, but is not judged to be in imminent danger of extinction. Threats include illegal hunting and increased vulnerability to killer whale predation as a result of reduced ice coverage.; La population comptait au moins 11 000 individus lorsque la pêche commerciale à la baleine a commencé. Cette pêche a réduit la population à moins de 30 % de son ancienne abondance. Des estimations récentes indiquent que la population s'accroà®t et qu'elle est plus grande que ce que l'on pensait, mais son nombre d'individus semblerait encore s'élever à moins de 3 000 individus, tous à¢ges confondus. La population remplit les conditions de la catégorie en voie de disparition, mais n'est pas considérée comme étant en danger imminent de disparition. Les menaces comprennent la chasse illégale et une vulnérabilité à la prédation de l'épaulard résultant de la couverture glaciaire réduite.

The population was severely reduced by commercial whaling between 1860 and 1915. Recent population estimates are uncertain, but indicate that there could be as few as 300 mature individuals, of which only half might be females. Threats to this small population include illegal hunting and increased vulnerability to killer whale predation as a result of reduced ice coverage.; La population a été gravement réduite par la pêche commerciale à la baleine entre 1860 et 1915. Les estimations récentes de la population sont incertaines, mais elles indiquent qu'il pourrait y avoir aussi peu que 300 individus matures, dont seulement la moitié serait composée de femelles. Les menaces pesant sur cette petite population comprennent la chasse illégale et une vulnérabilité accrue à la prédation de l'épaulard résultant de la couverture glaciaire réduite.

This population was hunted to low levels during commercial whaling. Although supporting a regulated hunt, it is recovering and is currently at about 50% of its historical population size. The population is not yet secure and is potentially negatively affected by climate change, and by oil and gas development.; Au temps de la pêche commerciale à la baleine, cette population a été intensément chassée. Elle semble en voie de se rétablir, même en présence d'une chasse réglementée; la population représente actuellement environ 50 % de sa taille historique. La population n'est cependant pas encore en sécurité et est potentiellement touchée de façon défavorable par le changement climatique ainsi que par l'exploitation pétrolière et gazière.

Assessment rationale/justification
Currently sighted only infrequently on former whaling grounds off British Columbia. Coastal whaling took at least 7,600 animals from the population between 1905 and 1967, and thousands of additional animals were taken by pelagic whalers through the 1970s. Catch rates from coastal whaling stations declined precipitously off British Columbia in the 1960s. Based on the severe depletion and lack of sufficient time for recovery, it is inferred that present population is below 50% of its level, 60-90 years ago. Individuals continue to be at risk from ship strikes and entanglement in fishing gear.; L'espèce est actuellement observée seulement de façon peu fréquente dans les anciens lieux de pêche à la baleine au large de la Colombie-Britannique. La pêche cà´tière à la baleine a réduit la population entre 1905 et 1967 d'au moins 7 600 individus, et des milliers d'autres individus ont été pris lors de pêches pélagiques durant les années 1970. Le taux des prises des stations de pêche cà´tière à la baleine a diminué de façon abrupte au large de la Colombie-Britannique au cours des années 1960. En se basant sur l'importante diminution de la population et un délai de temps insuffisant pour son rétablissement, on en a déduit que la population actuelle est inférieure à 50 % de son niveau d'il y a 60 à 90 ans. Les individus continuent d'être vulnérables aux collisions avec des navires et à l'enchevêtrement dans des engins de pêche.

Assessment rationale/justification
The size of this population was reduced by whaling during much of the 20th Century. However, sightings remain relatively common off Atlantic Canada and they have not been hunted since 1971. The current abundance and level of depletion compared with pre-whaling numbers are uncertain. The whales face a number of current threats including ship strikes and entanglement in fishing gear, but none is believed to seriously threaten the population.; La pêche à la baleine a réduit la taille de cette population pendant une grande partie du XXe siècle. Cependant, l'espèce est aperçue de façon relativement fréquente au large du Canada atlantique et n'est pas chassée depuis 1971. Son abondance et son niveau d'appauvrissement actuels comparativement aux niveaux qui existaient avant le début de la pêche à la baleine sont incertains. Les rorquals sont confrontés à un certain nombre de menaces, dont les collisions avec des navires et l'enchevêtrement dans des engins de pêche, mais aucune de ces dernières ne semblent menacer gravement la population.
