Book Description
A key goal of fisheries management is to regulate extractive pressure on a resource so as to ensure social, economic and ecological sustainability. This text provides an accessible entry point for students and professionals to management science as developed in fisheries, in order to facilitate uptake of the latest ideas and methods. Traditional management approaches have relied upon a stock assessment based on existing understanding of resource status and dynamics, and a prediction of the likely future response to a static management proposal. However all such predictions include an inherent degree of uncertainty, and the last few decades have seen the emergence of an adaptive approach that uses feedback control to account for unknown future behaviour. Feedback is achieved via a control rule, which defines a relationship between perceived status of the resource and a management action. Evaluations of such rules usually include computer simulation testing across a broad range of uncertainties, so that an appropriate and robust rule can be selected by stakeholders and managers. The book focuses on this approach, which is usually referred to as Management Strategy Evaluation. The book is enriched by case study examples from different parts of the world, as well as insights into the theory and practice from those actively involved in the science of fisheries management.

Book Description
Since the first volume of The Biology of Sea Turtles was published in 1997, the field has grown and matured in ways few of the authors would have predicted—particularly in the areas of physiology, behavior, genetics, and health. Volume III presents timely coverage of emerging areas as well as the integration of approaches and information that did not exist even a decade ago. The book assembles the foremost experts in each topic to provide the most up-to-date and comprehensive book on sea turtles available today. New areas covered include in vivo imaging of structure, spatial distributions of marine turtles at sea, epibiosis, imprinting, parasitology, and climatic effects. Life history is explored in three chapters covering age determination, predator-prey interactions, and mortality from bycatch. The Biology of Sea Turtles, Volume III will inspire scientists and students to explore and expand their understanding of these intriguing animals. The book provides clear baseline summaries, thoughtful syntheses, and effective presentation of the most fundamental topics spanning form and function, health, distributions, behavior, genetics, evolution, and ecology. Its scope and depth make it the definitive go-to reference in the field.

Book Description
The Guidelines to Prevent and Reduce Bycatch of Marine Mammals in Capture Fisheries were produced by FAO in response to the request from the Committee on Fisheries at its Thirty-third Session in 2018 to develop technical guidelines on this subject, and are directed at decision-makers, planners, managers and all those involved in developing and implementing policy and technical interventions which relate to the bycatch of marine mammals in fisheries.The guidelines were drafted and developed through a series of activities undertaken by FAO, including the Expert Workshop on Means and Methods for Reducing Marine Mammal Mortality in Fishing and Aquaculture Operations and the Expert Meeting to Develop Technical Guidelines to Reduce Bycatch of Marine Mammals in Capture Fisheries. They outline options for marine mammal bycatch reduction through the application of technical measures, including: spatial closures, the use of acoustic deterrents or alerting devices, modifications to fishing gear, changes in fishing operations and other strategies. The document refers to policy instruments and institutional frameworks that support the implementation of the guidelines and the conservation of marine mammals, in addition to awareness raising, communication and capacity-building actions, together with the special requirements of developing States. Finally, the guidelines address the future research and development needs for the prevention and reduction of marine mammal bycatch in capture fisheries.
