Distribucion de la abundancia de atun aleta amarilla (Thunnus albacares) y su relacion con la concentracion de pigmentos fotosinteticos medidos por satelite en aguas al sur de Mexico

In this paper the phytoplankton pigment concentration, as showed by the monthly composite images derived from the Coastal Zone Color Scanner of the Nimbus-7 satellite, were graphically related with maps of yellowfin tuna abundance from the logbook records of the mexican tuna purse seine fleet during 1984-1986. There is a relationship between yellowfin tuna abundance and the color fronts, regardless of phytoplankton pigment concentration. Moreover, data series made from the month average by area showed a lag of one season between the highest values of tuna abundance and the phytoplankton pigment concentration.
