The California drift gillnet fishery for broadbill swordfish, Xiphias gladius, and common thresher shark, Alopias
vulpinus, developed in the late 1970's when incidental catches of pelagic sharks in small-mesh coastal drift gillnets targeting barracuda, Sphyraena argentea, and white seabass, Atractoscion nobilis, motivated fishermen to experiment with large-mesh nets targeting thresher shark.
