Fact Sheet


Overfishing has created downward systemic pressure on ocean habitats and fish, threatening the viability of fish stocks and the health of the ocean.  In 2010, 30 percent of the stocks reported by FAO were either overexploited, depleted or recovering from depletion.

Sea Around Us findings suggest that FAO reports may underestimate fishery catch numbers by 30 to 50 percent in developed countries, and over 100 percent in many developing countries.  The need for analysis to evaluate total catch is critical in determining fisheries policy and providing food security in developing nations.


The Sea Around Us, a project at the University of British Columbia supported by the Paul G. Allan Family Foundation and Vulcan Inc., a Paul G. Allen company, provides reconstructed catch data to assess the impact of fisheries on marine ecosystems and offer mitigating solutions to stakeholders.  A lack of accurate or comprehensive data make efforts to stem the tide of overfishing difficult, limiting the chances of success.  The Sea Around Us provides one part of the solution – using reconstructed catch data for fisheries across the globe.


The Sea Around Us conducts reconstructions of catch data by analyzing additional available fisheries, socio-economic and population data sources.  Resultant reconstructed catch data are then allocated to  ½ degree longitude by ½ degree latitude cells by taxon and fishing country.  The reconstructed catch includes industrial, recreational, artisanal, subsistence, and discard activity, both reported and unreported.

The Sea Around Us offers reconstructed catch allocations that have ecological and policy relevance. Data are made available in multiple dimensions, including Exclusive Economic Zones, Regional Fisheries Management Organizations, Taxa, Fishing countries or Large Marine Ecosystems. Further, spatial scales now include High Seas, Global and FAO Areas.


Catch Allocation Map: The Sea Around Us website has powerful data visualization tools providing researchers the opportunity to search and view catch allocation data from 1950 through 2010 by one or more taxa, fishing countries or a combination of both. The map visualization features catch data distributed across ½ degree latitude-longitude cells.

Catch Allocation Graphs and Analysis Tools: Catch allocation pages provide users the opportunity to display, analyze and download data and references by multiple regions or taxa, as well as links to additional models, region and taxon information and ecological indicators. All allocated catch data is available for download via CSV file.

Resources and Tools:  The website also includes additional data on mariculture, integration with sites such as FAO, Ocean Heath Index, FishBase and other partners, and access to further studies, resource papers, key publications and presentations.
