Until now, there has been only one source of data on global fishery catches: information reported to the Food and Agriculture Organization of the United Nations by member countries. An extensive, ten-year study conducted by The Sea Around Us Project of the University of British Columbia shows that this catch data is fundamentally misleading. Many countries underreport the amount of fish caught (some by as much as 500%), while others such as China significantly overreport their catches. The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery data. This groundbreaking information has been gathered from independent sources by the world’s foremost fisheries experts, and edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project. The Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. National reports describe the state of the country's fishery, by sector; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations. While it has long been clear that the world’s oceans are in trouble, the lack of reliable data on fishery catches has obscured the scale, and nuances, of the crisis. The atlas shows that, globally, catches have declined rapidly since the 1980s, signaling an even more critical situation than previously understood. The Global Atlas of Marine Fisheries provides a comprehensive picture of our current predicament and steps that can be taken to ease it. For researchers, students, fishery managers, professionals in the fishing industry, and all others concerned with the status of the world’s fisheries, the Atlas will be an indispensable resource.

Rat eradications on tropical islands have been less successful than operations in temperate climates. This is likely due to poor understanding of the factors unique to tropical regions that rat populations respond to, such as high numbers of land crabs, aseasonal climates and habitats not found at higher latitudes. On Aldabra Atoll, southern Seychelles, black rats were monitored for one year in three habitats over three climatic seasons to investigate changes in density and breeding to inform planning for a possible rat eradication. Rats bred all year in mangrove forest and in two of three seasons, including the dry season, in Pemphis forest, probably resulting from the saline tolerance of these habitats: lush vegetation and seeds were available there during the dry season. In contrast, rats from the adjacent mixed-scrub habitat only bred in the wet season due to desiccation of vegetation and lack of fresh water during other times of the year. Bait consumption trials showed that all rats ingested dyed bait when applied at 15 kg/ha, despite high rat densities and substantial bait interference by non-target species, but not at an application rate of 10 kg/ha. A novel ‘bola’ technique was tested for distributing bait into mangrove forest, where aerially applied rat bait would normally be lost due to tidal inundation. The method is likely to improve rat exposure to bait in mangrove forest and other habitats on tropical islands, and warrants further development.
