Data on commercial vessel operating units for 1969 from the NMFS Statistics and Market News Division were processed to give the number of vessels with one, two, and three types of gear. A table in matrix form presents without duplication the number of vessels by gear type, with single-gear vessels shown in the principal diagonal, and two- and three-gear vessels to the right and left of the principal diagonal, respectively. A summary table gives the total number of vessels participating in a fishery by species and gear type.
