Genetic diversity and historical demography of Atlantic bigeye tuna (Thunnus obesus) [PDF]

Molecular Phylogenetics and Evolution, 2006
Bigeye (Thunnus obesus) is a large, pelagic, and migratory species of tuna that inhabits tropical and temperate marine waters worldwide. Previous studies based on mitochondrial RFLP data have shown that bigeye tunas from the Atlantic Ocean are the most interesting from a genetic point of view.

Evidence for a fisher-designed solution to manta and devil ray bycatch in tuna fisheries. [PDF]

Conserv Biol
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

Cameras or Divers? How Baited Remote Underwater Videos and 'Long Swims' Underwater Visual Census Complement Each Other on Coral Reefs. [PDF]

Ecol Evol
This study compares baited remote underwater videos (BRUV) and a rapid timed long swim (LS) UVC method to evaluate their ability in assessing relative abundance and diversity of large predatory reef fish from nine selected families. BRUVs were more effective in detecting mobile and bait‐attracted taxa such as Carangidae and recorded up to 28 unique ...

The relationship between the annual catch of bigeye tuna and climate factors and its prediction

Frontiers in Marine Science
IntroductionIn order to explore the impact of climate factors on bigeye tuna catch, monthly data of nine climate factors, including El Niño-related indices (Niño1 + 2, Niño3, Niño4, and Niño3.4), Southern Oscillation Index (SOI), North Atlantic ...

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

Comparative analysis of three bait types in deep-set pelagic longline gear in the Equatorial Atlantic Ocean

Boletim do Instituto de Pesca, 2022
The choice of bait is one of the fisheries tactics used to increase selectivity for particular target species. The performance of three bait types (mackerel, sardine, squid) was evaluated with a commercial vessel operating in the Equatorial Atlantic ...

Length-frequency compositions and weight–length relations for bigeye tuna, yellowfin tuna, and albacore (Perciformes: Scombrinae) in the Atlantic, Indian, and eastern Pacific oceans [PDF]

Acta Ichthyologica et Piscatoria, 2008
Background. Bigeye tuna, Thunnus obesus (Lowe, 1839); yellowfin tuna, Thunnus albacares (Bonnaterre, 1788); and albacore, Thunnus alalunga (Bonnaterre, 1788), are very important species for world fisheries.
