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.

Book Description
Poultry has a crucial place worldwide as the eggs and chicken meat are important and rich sources of protein, vitamins and minerals. Poultry provides rich organic manure and is an important source of income and employment to millions of farmers and other persons engaged in allied activities in the poultry industry. Chickens and turkeys that are commercially raised today are the result of many years of selection and breeding of two or more breeds to continually improve productivity. Poultry farming is the raising of domesticated birds such as chickens, ducks, turkeys and geese for the purpose of farming meat or eggs for food. Poultry are farmed in great numbers with chickens being the most numerous. More than 50 billion chickens are raised annually as a source of food, for both their meat and their eggs. The chicken industry is made up of meatproducing chickens and egg-producing chickens. The modern meat-type chicken is derived from the deep-breasted Cornish breed and has been selected with an emphasis on producing meat rather than eggs. Further processing of meat chickens has led to many new products geared to the convenienceminded consumer, such as boneless, skinless breasts. The turkey industry has developed strains of birds with an emphasis on meat production and breast size, as the white meat has a higher market value in the United States. Many pure breeds of poultry are raised for exhibition, hobby and/or breed preservation purposes. There is lots to discover with the comprehensive poultry production. We all know that in order to get the best out of birds, poultry keepers need to be up to date with the latest ideas and techniques. The book Avian (Poultry) Production discusses about the anatomy and physiology of birds, building them the best housing, breeding, egg production and also about preventing parasites and diseases.
