Big-picture & big-data science in fisheries: The global Sea Around Us research initiative Dirk Zeller Sea Around Us – Indian Ocean Already covered the definition of fisheries: The interaction of fish - with fishing gear - as deployed by fishers - at a certain location - at a certain time - and which results in catches Also touched on the role of FAO, as the only agency with an official global mandate, largely driven by governmental & inter-governmental mandates Introduce a government-independent scientific initiative focusing on global fisheries in a data context: - catch… volume & value in space and time - fishing effort - stock assessments - other fisheries parameters The Sea Around Us research initiative (www.seaaroundus.org) Sea Around Us Pauly D (2007) The Sea Around Us Project: Documenting and communicating global fisheries impacts on marine ecosystems.

Not politically or scientifically independent… Does not collect data Reports on data provided to FAO by countries Non-reporting issues Quality of data Time series comprehensiveness back to 1950… think USA versus Congo Does not modify/improve national data, although fills time gaps with previous years’ data Only accepts and uses data on landed catches… so-called ‘production’ FAO data & analyses cover only a subset Garibaldi L (2012) The FAO global capture production database: A six-decade effort to catch the trend.
