Abstract

The present study reports length-weight relationships for 25 species of reef fishes associated with large brown macroalgae (i.e., Lessonia trabeculata and Macrocystis pyrifera) from the northern and central rocky coast of Chile (Southeast Pacific Coast; 18°-33°S). Weight scaled to length with an average power of 2.85, close to the expected value of 3, meaning that the relationship between length and weight is close to an isometric growth. No latitudinal (i.e., spatial) and temporal variations were observed on the growth coefficient of the fish species studied.
