PESCA DEL PATUDO “Thunnus obesus” Bigeye tuna

A las 00:00 horas del 19 de Marzo  2013 comienza la veda del atun Patudo “Thunnus Obesus” o Atun Rojo en  ingles Bigeye Tuna.

La flota artesanal canaria finaliza esta noche a las 00:00 h la captura de atunes Patudos la “zafra” parece ser buena con ejemplares capturados de gran porte superando muchos de ellos los 200kg. de peso y de unos 1,70 metros de longitud. Acontinuación una imagenes de estos hermosos “bichos” descargados de el barco PIXAPE TENERIFE que  alimentarán   bastantes ¿japoneses?.

This species is important in commercial fisheries around the world. It is being effectively managed throughout the majority of its range, with the exception of the Western and Central Pacific stock. With the exception of the Western Pacific population, all other stocks are being fished below current maximum sustainable yield (MSY). Based on weighted declines of total biomass or spawning stock biomass (SSB) across all stocks, there has been an estimated 42% decline globally over the past 15 years (1992–2007), or three generation lengths. As the MSY of the Western and Central Pacific stock represents more than 20% of the global population, this species is listed as Vulnerable under Criterion A2. In addition, this species may undergo further declines if the mortality of the species in bycatch of the Skipjack fishery cannot be reduce.

Habitat and Biology
Epipelagic and mesopelagic in oceanic waters, occurring from the surface to about 250 m depth.
Temperature and thermocline depth seem to be the main environmental factors governing the vertical
and horizontal distribution of bigeye tuna. Water temperatures in which the species has been found range from 13° to 29° C,
but the optimum range lies between 17° and 22° C. This coincides with the temperature range of the permanent thermocline.
In fact, in the tropical western and central Pacific, major concentrations of T. obesus are in occurrence of
the species is closely related to seasonal and climatic changes
in surface temperature and thermocline Juveniles and small adults of bigeye tuna school at the surface in mono-species
groups or together with yellowfin tuna and/or skipjack.  Schools may be associated with floating objects.
In the eastern Pacific some spawning is recorded between 10° N and 10° S throughout the year, with a peak from April
through September in the northern hemisphere and between January and March in the southern hemisphere. Kume (1967)
found a correlation between the occurrence of sexually inactive bigeye tuna and a decrease of surface temperature below 23° or 24°
C. Mature fish spawn at least twice a year; the number of eggs per spawning has been estimated at 2.9 million to 6.3 million.
The food spectrum of bigeye tuna covers a variety of fish species, cephalopods and crustaceans, thus not diverging significantly from that of other
similar-sized tunas. Feeding occurs in daytime as well as at night.The main predators are large billfish and toothed whales.


Maximum fork length over 200 cm; common to 180 cm (corresponding to an age of at least 3 years).
The all-tackle angling record for the Pacific is a 197.3 kg fish from off Cabo Blanco, Peru in 1957
This fish was 236 cm long but it was not specified whether this pertained to fork length or total length.
For the Atlantic, the all-tackle angling record is a 170.3 kg fish with a fork length of 206 cm taken off Ocean City, Maryland,
USA in 1977. Maturity seems to be attained at 100 to 130 cm fork length in the eastern Pacific and in the Indian Ocean, and at about 130 cm in the central Pacific.
