Book Description
North Atlantic right whales (Eubalaena glacialis) are among the most critically endangered cetacean species in the world. Despite having protected status, both internationally and in Canadian waters, the right whale population that frequents Canadian waters remains at low abundance, with an estimated population of around 325 individuals (EC 2006). It has been estimated that at least thirty percent of right whale deaths result from their interaction with human activities, and entanglement in fishing gear is a significant cause for known injury and mortality (Knowlton and Kraus 2001). This report has identified the different gear types and fisheries that right whales encounter in Scotia-Fundy region, as well as the potential they pose for entanglement. Commercial landings data for the time series between 1999 and 2005 inclusive were used to assess the spatial and temporal distribution of fishing activity. These fishery distributions were compared to the patterns of right whale aggregation in Scotia-Fundy waters in order to estimate the potential for right whale/gear interaction among the different gear types/fisheries over time and space. Of all the gears that right whales encounter in their summer habitat, the groundfish gillnet, groundfish hook and line, and crab trap fisheries pose the greatest potential for entanglement. These gear types are relatively more likely to lead to entanglement because (1) these are the most active fisheries in Scotia-Fundy during the period of right whale aggregation, and (2) the design of the gears and their methods of deployment lend themselves to possible entanglements. The results of this study may be used to advise industry and management on actions that would minimize the risk of entanglement to right whales, while correspondingly minimizing any disruption of the commercial fisheries in the Scotia-Fundy region

Book Description
This report represents the first economic valuation of the ecosystem services provided by deep-sea sponges in the North Atlantic. It is based on information available in the scientific literature at the time of writing, but also indicates the research areas where discoveries and research advances are shortly expected. The report is aimed at a generic public with no specialized knowledge on sponges or on economic valuation. It is outlined in a way to provide essential background information, but makes reference to a comprehensive list of scientific publications for further insights.

Book Description
The Worldwide review of bottom fisheries in the high seas in 2016 is an update to the first Worldwide review of bottom fisheries in the high seas, published in 2009 based on information from 2003 to 2006. It provides states and other interested parties with a summary of the current status of high seas bottom fisheries worldwide. The present, updated review begins with a description of the demersal finfish and shellfish resources, before offering a global perspective on fisheries and management; it then provides specific, regional information over eleven chapters covering the high seas of the world’s oceans, by region. Drawing on data up to and including 2016, it provides a survey of the current state of bottom fisheries since the original Worldwide review, considering these fisheries in the context of their historical evolution.

Book Description
This policy document provides fishermen, companies, and other interested Canadians with a clear, consistent statement of Fisheries and Oceans policy respecting the registration of commercial fishermen and vessels, and the issuance of fishing licences to persons in Eastern Canada. The policy document also provides objectives against which the approriateness and effectiveness of specific policy measures can be evaluated. The document covers the legislative background and licensing objectives; the general policy framework; vessel replacement rules for vessels less than 19.8m (65') length; appeal process and procedures; amendment procedures; and terminology used.

Book Description
The book describes the main marine and coastal biological systems of Passamaquoddy Bay and adjacent waters and the oceanographic and meteorological characteristics of the area. Subject areas begin with meteorolgy and oceanography. The second group covers the intertidal systems with chapters on rocky intertidal shores, rock pools, coarse sedimentary shores and salt marshes. The third general section covers hard and sedimentary sublittoral habitats. Following chapters discuss pelagic systems under the headings fishes, phytoplankton, larger zooplankton, and microzooplankton. Three chapters deal with the birds, amphibians and reptiles, and marine mammals. Finally coastal vegetation is described.

Book Description
Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.
