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...
متن کاملTuna 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...
متن کاملTuna 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 ...

متن کاملAnalyses of Japanese Longline Operational Catch and Effort for Bigeye Tuna in the Wcpo
Analyses of operational-level, longline catch and effort data for bigeye tuna in the Western and Central Pacific Ocean were carried out under an agreement between the Secretariat of the Pacific Community and the Japan National Research Institute of Far Seas Fisheries. The objectives of the collaboration were to standardize bigeye CPUE, and to estimate the historical trend of longline catchabili...
