LOGLINEAR MODELS FOR STUDYING ASSOCIATION S BETWEEN CATCHES PER UNIT EFFORT AND HYDROCLIMATIC VARIABLES

In this paper we study associations between categorical variables. We present an approach based on loglinear modelling. A better knowledge o f the influence of the intensity of tidal coefficient (cm) and of the rate of river flow (df) on catch per unit effort (cpue) of allis shad (Alosa alosa) was obtained. Analysis performed indicated that an incre ase of catch per unit effort is proportionally associated with the inc rease in the tidal coefficient. We also noted the influence of the rat e of flow.
