Tuna schools / aggregations in surface longline data 1993 – 98

Exploratory data analysis of a highresolution (hook-by-hook), 6-year time series (1993– 98) of observed longline catch data for tunas was used to investigate fine-scale spatial patterns along individual sets that may be indicative of social behaviour (i.e., schooling) and/or the response of individual fish to favourable extrinsic conditions (i.e., aggregation). Methods of spatial data analysis ...

Tuna Longline Catch Rates in the Indian Ocean

Myers and Worm’s recent letter to the editor raise serious concerns about the impacts of the industrial fishing on large predatory fish and the associated biological community in four continental shelf and nine pelagic oceanic systems. They suggest that in these systems industrial fisheries have removed 90% of the large predators and that these removals may compromise the sustainability of fish...

Tuna Longline Fishing around West and Central Pacific Seamounts

BACKGROUND Seamounts have been identified as aggregating locations for pelagic biodiversity including tuna; however the topography and prevailing oceanography differ between seamounts and not all are important for tuna. Although a relatively common feature in oceanic ecosystems, little information is available that identifies those that are biologically important. Improved knowledge offers oppo...

Sea level height , sea surface temperature , and tuna yields in the Panama bight during El Niño

Between 1988 and 1998, annual tuna landings at Buenaventura (Colombian Pacific) are correlated with the sea surface temperature in the central Equatorial Pacific (r=0.78, p<0.05) and the sea level height at Buenaventura (r=0.76, p<0.05) and Balboa (Panama) (r=0.79, p<0.05). Seasonal oceanic upwelling is forced by the Panama wind jet, which may favour oceanic fisheries such as tuna. Here we firs...
