Longline Fishing for Deep-Swimming Tunas in the Central Pacific, August-November 1952. E-book

The Cavalieri cruise warrants special mention because it represented an attempt at commercially harvesting the equatorial longline tuna resource. During this cruise considerably more gear was fished than during experimental surveys by pofi vessels. The design of the gear was identical to that used by pofi, and the daily fishing schedule was comparable except that more time was spent setting and hauling the greater number of baskets fished.
