Available in PDF, EPUB and Kindle. Book excerpt: "In 2004, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) recommended that Cumberland Sound Beluga (CSB) be designated as "Threatened" under the Species at Risk Act (SARA). Continued research and monitoring of this beluga population is required to ensure sustainability of the Inuit subsistence harvest. Fisheries Management and its Nunavut co-management partners are developing an Integrated Fisheries Management Plan (IFMP) with the community of Pangnirtung. An aerial survey of Cumberland Sound beluga was conducted in summer 2014. Based upon this survey, Fisheries and Oceans Canada (DFO) was asked to provide Science Advice that can be considered by the Nunavut Wildlife Management Board (NWMB) to evaluate the sustainability of the current quota, and the level of Total Allowable Harvest (TAH) and Basic Needs Level (BNL) to be established for this beluga population."--Summary, p. iv.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents proceedings of a workshop to review four presentations and draft a stock status report on Cumberland Sound belugas, and to start drafting a recovery strategy for that beluga population. The four presentations summarized recent research on seasonal movements & habitat use, genetic & contaminant profiles, population size & trend, and population modelling & risk analysis of Cumberland Sound belugas. These presentations provided pertinent information and served as a basis for discussion to aid in drafting the stock status report.
Download or read book Detecting Changes in Population Trends for Cook Inlet Beluga Whales Delphinapterus Leucas Using Alternative Schedules for Aerial Surveys written by Roderick C. Hobbs and published by . This book was released on 2013 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Measuring population trends, and detecting a change in the trend, of Cook Inlet beluga whales (CIB), Delphinapterus leucas, has a specific role in the co-management agreement that determines harvest levels, and a more general application in the management of the population. Currently, an annual aerial survey schedule has provided abundance estimates from which growth trends for this population are determined. Under the harvest co-management agreement, the measured trend over a 10-year period is used to classify the population into one of three growth categories ('high', 'intermediate', or 'low'; Appendix). The growth category, along with the average abundance over the last 5-year period, is used to determine the number of takes allowed over the next 5-year hunting period (Appendix). For a more general application, we would like to be able to detect a change in the growth rate of the population that results from a change in the underlying life history parameters such as birth interval and rates of survival and identify the year that the change occurred"--Introduction.

Download or read book Aerial Surveys Abundance and Distribution of Beluga Whales Delphinapterus Leucas in Cook Inlet Alaska June 2016 written by Kim E. W. Shelden and published by . This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS) has conducted aerial surveys to estimate abundance of the beluga population in Cook Inlet, Alaska, each June, July, or both from 1993 to 2012, after which biennial surveys began in 2014. The current document presents survey results and subsequent analyses yielding an abundance estimate and population trend based on data collected during June 2016. Surveys occurred May 31 - June 9, 2016 (49.2 flight hours). All surveys were flown in twin-engine, high-wing aircraft (i.e., an Aero Commander) at a target altitude of 244 m (800 ft) and speed of 185 km/hour (100 knots), consistent with NMFS' surveys of Cook Inlet conducted in previous years. Tracklines were flown 1.4 km from the shoreline, along the entire Cook Inlet coast, including islands. Additionally, sawtooth pattern tracklines were flown across the inlet in 2016. These aerial surveys effectively covered 40% of the total surface area of Cook Inlet and 100% of the coastline. In particular, most of the upper inlet, north of the East and West Foreland where beluga whales are consistently found, was surveyed seven times (out of seven attempts). Paired, independent observers searched on the coastal side of the plane, where most beluga sightings occur, while a single observer searched on the inlet side. A computer operator/data recorder periodically monitored distance from the shoreline (1.4 km) with a clinometer (angle 10°). After finding beluga groups, a series of aerial passes allowed all observers to each make independent counts of every group. In addition, whale groups were video recorded for later analysis and more precise counts in the laboratory. [doi:10.7289/V5/AFSC-PR-2017-09 (https://doi.org/10.7289/V5/AFSC-PR-2017-09)]
