Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.

Hammill and published by . This book was released on 2019 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The potential benefits of relocating live stranded or entrapped beluga to recovery of the St. Lawrence Estuary (SLE) beluga population were examined using a demographic model. The population is currently declining and information on reproduction rates are lacking. It is not possible to determine if the current decline is due to low reproductive rates, elevated mortality among neonates, or both. Adult survival is already quite high and there is unlikely much room for further improvement. Efforts to improve survival of neonates and juveniles are most likely to benefit population recovery. However, considerable numbers of animals must be assisted and successfully relocated each year to improve survival and halt the decline in population trend. Reports of live-stranded neonates or entrapped juveniles are infrequent. Therefore, the benefit of relocating these few individuals to population recovery is nil, and does not meet the objectives of Conservation Translocation. The occurrences of entrapped juveniles are rare, but if in good health these animals are more likely to survive when relocated compared to abandoned neonates. From a conservation perspective, the benefit of relocating entrapped juveniles to the population as a whole is likely nil given the rarity of these events. However, relocating these individuals may be considered on other grounds. Some of the factors that need to be considered have been identified (e.g. DFO Release and Rehabilitation Criteria)"--Abstract, p. iii.

This book was released on 2017 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The beluga is an Arctic species, and the St. Lawrence Estuary (SLE) population is at the southernmost limit of the species distribution. Up until 2007, the population appeared to be stable. However, unusually high numbers of young of the year found dead in 2008 and 2012, and a low aerial photographic estimate of abundance in 2009, triggered a review of the population status in 2013. Based largely on this review, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) re-evaluated the status of SLE beluga in 2014, and recommended that the population be designated as ‘Endangered’ (COSEWIC 2014). Here, we present a new abundance index of SLE beluga from a series of eight visual aerial systematic line-transect surveys flown in August and September 2014. This will be used to evaluate trends in abundance along with the 36 visual surveys completed with similar methods since 2001. We also present an update on the number of beluga carcasses that have been recovered since the last assessment (DFO 2014)"--Introd., p. 1, 2.

This book was released on 2017 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The St. Lawrence Estuary (SLE) beluga population is located at the southernmost limit of the species range. It occurs primarily in the SLE and seasonally in the Gulf of St. Lawrence. A review of the population status (2007) concluded that the population over the period 1988-2007 was stable. However, in recent years there has been an increase in reported deaths of young-of-the-year and an apparent increase in perinatal mortalities. This increase as well as change in the age/sex structure of the deaths suggests that its status may have changed. A review in 2013 incorporated carcass monitoring and aerial survey data into a population model. The model results indicate that the population was slightly increasing from the 1960s to the early 2000s and has probably declined, to under 1000 animals during the last decade. The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated the population as ‘endangered’ in 2014, and its status is "threatened" according to the Species at Risk Act. In 2014, new aerial surveys were flown. The Species at Risk directorate requested that these surveys be reviewed and that the number of reported deaths be updated"--Context, p. [1].

This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St. Lawrence Estuary beluga population was listed as threatened under SARA in May 2005. In 1986, Fisheries and Oceans Canada set up the Ad Hoc Committee for the conservation of the St. Lawrence beluga, the objectives of which were to identify factors that threatened the population's survival and to make recommendations to favour its recovery. This project was carried out jointly by Fisheries and Oceans Canada and Environment Canada from 1988 to 1993 as part of the St. Lawrence Action Plan (SLAP), with the following objectives: to minimize disturbance to the beluga population, to combat the discharge and spread of toxic chemical products, and to conduct further research on the beluga. A fourth objective was added in 1989: to facilitate public access to information in order to raise awareness in Canada and Quebec of the St. Lawrence beluga. This document includes information about recovery and background of the beluga whale in the St. Lawrence Estuary.--Includes text from document.
