Abstract

In this paper, results of the bottom longline analysis demonstrate that bait consumers’ fauna significantly influences the catchability coefficient and the crustaceans, that are non-susceptible to catch, showed great influence in that variation. Moreover, the demonstration of the existence of significant associations among the species captured and non-captured suggests the possibility of correlating the capture composition and the variation of the catchability coefficient.
