This excellent second edition has been fully updated and expanded and is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. The book now includes an additional chapter on marine ecology due to the increasing recognition of the need to manage ecosystems as well as fish stocks. Chapters on parameter estimation and stock assessment now include step-by-step instructions on building computer spreadsheet models, including simulations with random variations that realistically emulate the vagaries of nature. Sections on ecosystem management, co-management, community-based management and marine protected areas have been expanded to match the increased interest in these areas.
