Our understanding of the biology Atlantic bluefin tuna (Thunnus thynnus) has increased profoundly in last decade, and progress is attributed to development application a variety novel tools. Here we provide comprehensive examination available data on life history stock structure T. thynnus by re-examining current databases literature highlighting findings from recent studies using approaches such as archival tags natural markers (e.g., genetics, otolith chemistry). The present review...
Uncertainty regarding the movement and population exchange of Atlantic bluefin tuna (Thunnus thynnus) from two primary spawning areas (Gulf Mexico, Mediterranean Sea) is increasingly implicated as a major impediment for conservation this species. Here, mixture methods were applied to natural chemical markers (18O 13C) in otoliths (ear stones) comprehensively investigate nature degree transoceanic mixing eastern western populations several North Ocean that potentially represent hotspots....
Abstract Relative indices of abundance by age class for bluefin tuna from 1975 to 2000 were estimated using generalized linear mixed models. Age was included as a fixed factor within the model specifications, with Year×Age interaction component in order obtain annual age. Catch and effort data on available two sources, catches trip, daily logbooks. Catches modelled delta-lognormal model. The finally selected following explanatory factors: Year, Age, Year×Age, Month, number Crew, Bait Tanks,...
The compiled data for this study represents the first Atlantic and Mediterranean-wide effort to pool all available biometric bluefin tuna (Thunnus thynnus) with collaboration of many countries scientific groups. Biometric relationships were based on an extensive sampling (over 140,000 fish sampled), covering most fishing areas species in North Ocean Mediterranean Sea. Sensitivity analyses carried out evaluate representativeness explore adequate procedure fit weight-length relationship (WLR)....
This study deals with important methodology issues that affect age estimates of eastern Atlantic bluefin tuna Thunnus thynnus using dorsal fin spines. Nearly 3800 spine sections were used from fish caught in the north‐east Ocean and western Mediterranean Sea over a 21 year period. Edge type marginal increment analyses indicated yearly periodicity annulus formation translucent bands (50% occurrence) appearing October to May. Nucleus vascularization seriously affected specimens older than 6...
Skin and gill parasites found in juvenile Atlantic bluefin tuna (Thunnus thynnus) caught the Bay of Biscay, northeast Atlantic, were examined with aim finding biological tags. The degree infection different microhabitats was analyzed annual prevalence by species parasite obtained. Of specimens examined, 98% had parasites, gills far most infected microhabitat, followed skin pectoral fin. Within cavity, commonly afferent margins primary lamellae. Three Copepoda identified, two Monogenea,...
