Book Description
The long-finned pilot whale, Globicephala melas, is a widely distributed pelagic species found in cold temperate waters of the North Atlantic and southern hemisphere. This report reviews the conservation status of this species. It includes information on the whale's geographic distribution, population size and trends, protection status, habitat, general biology, species movement and behaviour, factors limiting the whale population size and distribution, and the special significance of the species for Canada. Concludes with discussion of the current consensus regarding the status of the species.

Book Description
"The selection of species to include in this book was based on two principles: 1. Those that in recent times had a viable, naturally occurring wild population in Canada, its continental islands, or in the marine waters of its continental shelf ... [and] 2. Species introduced into Canada by humans"--P. xiv.

Book Description
Fish in U.S. waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem. During the past 40 years, the ecosystem has experienced extensive fishing by domestic and foreign fleets, changes in ocean water temperatures due to climate change, and pressures from increasing human populations along the coast. This report highlights the need to understand natural and human-related changes in this region and to develop effective management and mitigation strategies. These changes have been linked to changes in the distribution and abundance of fish species in the region and their major sources of food. Illus.

Book Description
The Bottlenose Dolphin Tursiops truncatus, is distributed worldwide in warm temperature and tropical waters. This report reviews the general biology, worldwide status and management of this species, with special reference to its status in Canadian waters. The report derives information from both currently accepted forms and previous species designations, and the wide range in many characters reflects both intra- and inter-population variability.

Book Description
Interest in marine mammals has increased dramatically in the last few decades, as evidenced by the number of books, scientific papers, and conferences devoted to these animals. Nowadays, a conference on marine mammals can attract between one and two thousand scientists from around the world. This upsurge of interest has resulted in a body of knowledge which, in many cases, has identified major conservation problems facing particular species. At the same time, this knowledge and the associated activities of environmental organisations have served to introduce marine mammals to a receptive public, to the extent that they are now perceived by many as the living icons of biodiversity conservation. Much of the impetus for the current interest in marine mammal conservation comes from "Save the Whale" campaigns started in the 1960s by environmental groups around the world, in response to declining whale populations after over-exploitation by humans. This public pressure led to an international moratorium on whaling recommended in 1972 by the United Nations Conference on the Human Environment in Stockholm, Sweden, and eventually adopted by the International Whaling Commission ten years later. This moratorium largely holds sway to this day, and further protective measures have included the delimitation of extensive areas of the Indian Ocean (1979) and Southern Ocean (1994) as whale sanctuaries.

Book Description
Newfoundland and Labrador has a long history of commercial whaling, beginning in the first half of the sixteenth century when Basque whalers established seasonal stations on the Labrador coast from which to hunt bowheads and North Atlantic right whales. Anthony Dickinson and Chesley Sanger examine the region's modern shore-station industry from its beginnings in 1896 to its peak catch season in 1904 through subsequent cycles of decline and revival until its enforced closure in 1972 by the federal government.Modern shore-station whaling on Canada's eastern shores developed with the spread of Norwegian-dominated whaling from local areas where stocks that had been depleted by new hunting technologies to more productive locations in the North Atlantic and elsewhere. Twentieth-Century Shore-Station Whaling in Newfoundland and Labrador adds to a growing number of regionally specific case studies that collectively illustrate the complex nature of the history of global whaling. Dickinson and Sanger further demonstrate how participants in the industry were instrumental in developing other whaling initiatives, including those in British Columbia.
