Global Atlas of Marine Fisheries: A critical appraisal of catches and ecosystem impacts

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.

The freshwater ichthyofauna of the Fiji islands remained poorly documented before the establishment of the Pacific-Asia Biodiversity Transect (PABITRA) network. The PABITRA approach assesses biodiversity along ocean-to-mountain transects and promotes sustainable land use on islands across the Pacific. Multiple surveys of freshwater fish species along the Viti Levu PABITRA transect have contributed six new occurrence records and one new species to the known freshwater fishes of Fiji since 2002. In total, 21 indigenous species of fish (9% endemic) from 10 families and no introduced fishes were found in the three PABITRA sites. Diversity was highest (16 species) at Savura forest reserve and decreased further inland into Sovi and Wabu. The assemblage found is dominated by highly migratory species (95%) that traverse the different aquatic habitats (marine, estuarine, lowland and upland streams) covered by the PABITRA transect. This high degree of connectivity highlights several growing issues affecting aquatic fauna on the high island of Viti Levu. The reduction in forest cover along the gateway transects, especially in the terminal reaches, and infrastructure development such as dams and weirs have deleterious effects on the migration routes of the Fijian ichthyofauna. Several species collected are important food sources and have cultural totemic importance to local inhabitants along the vertical transect. This paper documents the ichthyofauna of the Fiji gateway transect, ecological characteristics of this assemblage, IUCN Redlist conservation assessment status and highlights factors affecting the fragility and resilience of these communities, particularly focusing on the importance of life-history patterns and watershed conditions.
Thesis: Water resources on outer-lying islands in Micronesia

Pacific islands are long-settled by mankind, dating back several hundreds to thousands of years ago since discovery by islanders traveling by boat. Amongst these islands are atoll islands, which are small coral islands that lie at a low elevation and are usually part of a ring-like coral reef formation. Past and present islanders collect water from rainwater catchments and groundwater wells, with rainwater used primarily for drinking water and groundwater used as a supplement for wash water. Unfortunately, this region can experience severe drought, over-wash events during strong tropical storms, and typhoons, all of which threaten the freshwater supply for these islands. Due to rising concerns over climate change, there is interest in studying the water security of these especially vulnerable land forms. This thesis evaluates the reliability of the water supplies on four atoll islands in Yap, Micronesia by modeling the reliability of the two main sources. To first analyze rainwater catchment performance, Ifalik Island is evaluated using data collected on the island in 2015 by a collaborative research field team and a water balance model. Second, the results are used to develop design curves as a tool for rainwater catchment design and improvement. The fresh groundwater source is also modeled for each of the four islands to test the effects of varying climate conditions on the shallow, freshwater lens. Rainwater catchment systems on Ifalik Island are evaluated for their performance using a mass balance model that quantifies water storage through time. Performance is quantified primarily by reliability, which is a term to represent the percentage of days a rainwater catchment supplies sufficient water to the users. Based on the data from the Ifalik field survey, ii the average household rainwater catchment system on Ifalik uses a 16.5 square meter guttered roof with a 2,000 liter storage tank and serves seven individuals at 12 liters per capita per day. As a result of a rainwater catchment system sensitivity analyses based on the average rainwater catchment conditions, the most important factors in performance are effective roof area size, water demand, and gutter-downspout efficiency. Further analyses using the mass balance model found that the performance of each individual catchment is sufficient to provide water to the community during conditions similar to the severe drought year of 1997-1998, as well as projected rainfall conditions for the next 30 years. Therefore, analyses suggest Ifalik Island has sufficient rainwater catchment performance to provide water for the community. However, to introduce a conservative measure for water security, it is recommended that the catchment area be extended to the full size of the roof area. This would thereby increase the storage supply for the community by 25 cubic meters on the day of lowest supply under the 1997-1998 severe drought conditions.
