Abstract

Length-weight relationships for seven fish species caught from tidepools in an intertidal rocky shore in the Gulf of Cadiz are presented. Fish were sampled monthly (April 2008–January 2012), using hand nets (mesh size 1.5 mm). The values of b parameter remained within the expected range of 2.5–3.5 for all fish species. An ANCOVA test was used to evaluate differences in the b growth parameter between females and males. Gobius cobitis, G. incognitus and G. paganellus showed significant differences in the parameters of the length-weight relationships according to the sex.
