ABSTRACT: Database belong to the
Programa Nacional de Aprovechamiento del Atún y Protección de los Delfines
(PNAAPD) from México. The area covers from latitude 5 to 20 N and longitude 90
to 125 W, Eastern Pacific Ocean (EPO), for 1998, 2001, 2002, 2005 and 2006
includes date, geographical position, sea surface temperature, tuna’s catch,
yellowfin tuna’s size and dolphin’s number. 5 degress squares of latitude and
longitude, each year were made. Yellowfin tuna number was normally distributed
(KSd = 0.02, P > 0.20). The problem to solve is the relationship of the
spotted dolphin and yellowfin tuna, that may analyze in the background of a non
linear generalized model. Considering the array of latitude and longitude over
the years that the abundance of yellowfin tuna is a dependent variable and the
spotted dolphin abundance is the covariance continuous variable, the
interaction and covariance, indicates a significant contribution to
variability. The tuna abundance index does produce significative differences in
latitude and longitude. Considering the dolphin as a dependent variable and the
yellowfin tuna as a covariance continuous variable, the dolphin abundance index
produced significative differences in latitude and longitude.
