This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.

Algae have been used since ancient times as food, fodder, fertilizer and as source of medicine. Nowadays seaweeds represent an unlimited source of the raw materials used in pharmaceutical, food industries, medicine and cosmetics. They are nutritionally valuable as fresh or dried vegetables, or as ingredients in a wide variety of prepared foods. In particular, seaweeds contain significant quantities of protein, lipids, minerals and vitamins. There is limited information about the role of algae and algal metabolites in medicine. Only a few taxa have been studied for their use in medicine. Many traditional cultures report curative powers from selected alga, in particular tropical and subtropical marine forms. This is especially true in the maritime areas of Asia, where the sea plays a significant role in daily activities. Nonetheless, at present, only a few genera and species of algae are involved in aspects of medicine and therapy. Beneficial uses of algae or algal products include those that may mimic specific manifestations of human diseases, production of antibiotic compounds, or improvement of human nutrition in obstetrics, dental research, thallassotherapy, and forensic medicine.

Taking a social science approach, this book explores the governance of sustainable seafood, which is fundamental to food and nutrition security as well as being an important source of income and employment in many regions. Due to the importance of protein and other fishery and aquaculture by-products, many wild fisheries are coming under pressure, and this increasing demand has created a strong driver to expand aquaculture. As a result, the social and environmental sustainability of these production systems have come into question. The authors of the book explore the governance of sustainable seafood, taking into account the rise of social movements through environmental non-governmental organisations, the nature and perceived limits of government regulation within and beyond the state, and the promise of market-based approaches to governance such as ecolabelling. The book focuses on how concern over sustainable seafood has been translated into different current forms of governance. It then assesses what alternative governance approaches are starting to emerge that combine movements, states and markets for sustainable seafood production and consumption, and their effects. The book concludes with a vision for the future through key principles for evaluating the collective impact of governing sustainable seafood. This timely volume will be key reading for researchers interested in fisheries and aquaculture governance, as well as coastal and marine policies and sustainable food movements more broadly. It will also be of interest to practitioners and policymakers engaged in creating fishery policies and sustainable fishery development.
