Maintained by the Fisheries Statistics & Economics Division of the National Marine Fisheries Service, this spectacular foreign trade data base includes annual and monthly data since 1975 and is constantly updated as new information becomes available. For scientists interested in quantifying or tracking human impact on marine ecosystems, this site is a veritable gold mine. The database offers three types of data, all of which are searchable and may be downloaded: imports of fishery products, exports, and re-exports. Trade data exist for all countries with which the US conducts trade. A new feature increases the worth of this already valuable site: users can, with the help of explicit instructions, "build a database" (for download), organized by specified countries and time periods.
