Book Description
This is the first comprehensive look at the taxonomy, life history, and conservation status of the world's trout and char. These are fascinating and beautiful fish that rate high for the angler as well as for tourist and recreational economies. Trout and char also play key roles in the ecology of many lake and river systems around the world. Trout and char are abundant in many regions, but most native species are on the decline. Some are classified as vulnerable, threatened, or endangered. Because of their widespread stocking in regions where they are not native, some trout and char also are the cause for threats to other native species. Loss of habitat, an expanding human population, and rapid climate change are challenging their future as streams warm and waters become more variable in their flows. This book examines trout and char from all these perspectives. Early chapters explore the unique diversity and life history aspects of trout and char and provide information on the taxonomy and systematics while also detailing some of unique life histories. New information is presented about species diversity and distributions by country. Summary chapters explore significant conservation and management challenges of broad interest to scientists, resource managers, anglers, and interested public. Trout and Char of the World end s with a series of essays exploring the future of trout and char over the next 50 years. Trout and Char of the World will be a primary resource for trout and char biologists, conservationists, and anglers in the many countries where trout and char are native or have been introduced, and a resource for anyone interested in learning more about the diversity and distribution of trout and char worldwide.--

Book Description
'The Sunken Billions: The Economic Justification for Fisheries Reform' shows the difference between the potential and actual net economic benefits from marine fisheries is about $50 billion per year, or some $2 trillion over the last three decades. If fish stocks were rebuilt, the current marine catch could be achieved with approximately half the current global fishing effort. This illustrates the massive overcapacity of the global fleet. The excess competition for the limited fish resources results in declining productivity, economic inefficiency, and depressed fisher incomes. The focus on the deteriorating biological health of world fisheries has tended to obscure their equally critical economic health. Achieving sustainable fisheries presents challenges not only of biology and ecology, but also of managing political and economic processes and replacing pernicious incentives with those that foster improved governance and responsible stewardship. Improved governance of marine fisheries could regain a substantial part of this annual economic loss and contribute to economic growth. Fisheries governance reform is a long-term process requiring political will and consensus vision, built through broad stakeholder dialogue. Reforms will require investment in good governance, including strengthening marine tenure systems and reducing illegal fishing and harmful subsidies. Realizing the potential economic benefits of fisheries means reducing fishing effort and capacity. To offset the associated social adjustment costs, successful reforms should provide for social safety nets and alternative economic opportunities for affected communities.
