dc.description.abstractIn this work, a stochastic model is presented in order to analyze the behavior over time, between the observed changes in sea surface temperature and its relationship with the catch and abundance of the Goldfish species, in a specific area of the Colombian Pacific. Estimation methods such as maximum likelihood and the Euler-Maruyama method are applied in order to estimate the model parameters and estimate values of sea surface temperature, species abundance and catch per unit of effort for the species under study, between the years 2000-2012. Finally, the simulation results of the exposed model are presented and a sensitivity analysis is developed for the estimated parameters.
dc.description.abstractEn este trabajo se presenta un modelo estocástico que permite analizar el comportamiento, a lo largo del tiempo, entre los cambios observados de temperatura superficial del mar y su relación con la captura y abundancia de la especie pez Dorado, en una zona específica del Pacífico Colombiano. Se aplican métodos de estimación como máxima verosimilitud y el método de Euler-Maruyama con el propósito de estimar los parámetros del modelo y estimar valores de temperatura superficial del mar, abundancia de la especie y captura por unidad de esfuerzo para la especie en estudio, durante el periodo comprendido entre los años 2000-2012. Finalmente se presentan los resultados de la simulación del modelo expuesto y se desarrolla un análisis de sensibilidad para los parámetros estimados.
