The movement parameters of yellow fin tuna schools were analyzed by means of scanning sonar in tuna purse seine capture situations in the Oman Sea in June 2010. There was significant difference in swimming speed and radial swimming direction between the escaped and captured schools. In escaped cases, the fish schools swam faster with mostly horizontal avoidance behavior to the sound stimuli fro...

Effects of gear characteristics on the presence of bigeye tuna (Thunnus obesus) in the catches of the purse-seine fishery of the eastern Pacific Overfishing of bigeye tuna in the eastern Pacific Ocean has motivated a search for pratical means of reducing bigeye catch. We develop a classification algorithm for the presence/absence of bigeye in purse-seine sets on floating objects, the dominant m...

Purse seining for tropical tuna is one of the most technologically advanced fisheries in the world. The purpose of this study was to apply Local Ecological Knowledge (LEK) to assist in the planning of future in situ studies of fish behaviour around Drifting Fish Aggregating Devices (DFADs) by prioritizing research topics, thereby reducing the number of potential hypotheses to explore. Interview...

,:From its start nearly 60 years ago the California tuna fishery has ',own into the state's largest fishery, both in val)le and in pounds "nded (Power, 1960). Yellowfin tuna (Neothunnus macropterus) and ~, ,'pjack (][atwwonus pelarnis) now are the two most important species , nd comprise the bulk of the California tuna landings. These are topical tunas and seldom enter California waters in comm...
