Book Description
"Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

Book Description
Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.

Book Description
Proceedings of a workshop, the scientific reviews and the contributed papers presented at the symposium. The document presents a brief historical summary of marine research in the Gulf; reports the discussions, conclusions and recommendations of the different working groups on oceanography (physics, biology, chemistry and sedimentology) and on the fishery (fish and invertebrates); then presents the discussions of each multidisciplinary working group, centered around how the St. Lawrence system may be used as a natural laboratory which will contribute to the solution of major long-term problems of conservation of natural resources and of the quality of the environment.
