Pre-2002 IDCPA Reports

Reports of scientific research conducted by the Southwest Fisheries Science Center under the International Dolphin Conservation Program Act (IDCPA), and completed by December 31, 2002, are available below. These are the reports on which the dolphin-safe labeling decision of 2002 was based. Subsequent research is reported in later papers and reports.25XBinoc.jpg
