Book Description
Atlantic Fishes of Canada is intended as a replacement volume for Fishes of the Atlantic Coast of Canada, which was published in 1966 as Bulletin 155 of the Fisheries Research Board of Canada. The major portion of the present book is concerned with the biology, distribution, and/or economics of the fishes occurring off our Atlantic coast. Most accounts are well documented, necessitating an extensive reference list, which we hope will prove useful in itself. A checklist and keys are also presented for students or anyone concerned with the kinds and identification of fishes making up the fauna of the region. Many changes have occurred since 1966, not only in the state of our knowledge of the fauna and its biology but also in the management of the resource. Changes in the management are well documented in the section 'Atlantic Coast Fisheries and Fisheries Research in the Last 25 Years.'

Discards in the World's Marine Fisheries
Author: Kieran Kelleher
Publisher: Food & Agriculture Org.
ISBN: 9789251052891
Category : Business & Economics
Languages : en
Pages : 156
Book Description
This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.

The Ecosystem Approach to Fisheries
Author: S. M. Garcia
Publisher: Food & Agriculture Org.
ISBN: 9789251049600
Category : Technology & Engineering
Languages : en
Pages : 84
Book Description
Ecosystems are complex and dynamic natural units that produce goods and services beyond those of benefit to fisheries. Because fisheries have a direct impact on the ecosystem, which is also impacted by other human activities, they need to be managed in an ecosystem context. The meaning of the terms "ecosystem management", "ecosystem-based management", "ecosystem approach to fisheries" (EAF), etc., are still not universally defined and progressively evolving. The justification of EAF is evident in the characteristics of an exploited ecosystem and the impacts resulting from fisheries and other activities. The rich set of international agreements of relevance to EAF contains a large number of principles and conceptual objectives. Both provide a fundamental guidance and a significant challenge for the implementation of EAF. The available international instruments also provide the institutional foundations for EAF. The FAO Code of Conduct for Responsible Fisheries is particularly important in this respect and contains provisions for practically all aspects of the approach. One major difficulty in defining EAF lies precisely in turning the available concepts and principles into operational objectives from which an EAF management plan would more easily be developed. The paper discusses these together with the types of action needed to achieve them. Experience in EAF implementation is still limited but some issues are already apparent,e.g. in added complexity, insufficient capacity, slow implementation, need for a pragmatic approach, etc. It is argued, in conclusion, that the future of EAF and fisheries depends on the way in which the two fundamental concepts of fisheries management and ecosystem management, and their respective stakeholders, will join efforts or collide.

Economic valuation of ecosystem services provided by deep-sea sponges
Author: Ottaviani, D.
Publisher: Food & Agriculture Org.
ISBN: 9251336776
Category : Technology & Engineering
Languages : en
Pages : 97
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.
