Abstract
The spawning period and proportion of mature at length during the period 1984-2006 were investigated in a population of Tadpole codling (Salilota australis) off southern austral zone, Chile. Macroscopic aspects and gonadosomatic index (GSI) variability indicate presence of mature individuals across the year with an important spawning period between August and September. Significant differences between sex were detected in such processes as maturity schedule and somatic growth, particularly in females which grow larger than males. Progressively Salilota australis has become an important target specie for the austral demersal fleet in Chile, showing both an average catch length greater than the length at 50% maturity (LM) and a high female fishery availability. Because the unknown vulnerability to overfishing of Salilota australia, the life history parameter analysis must be a priority needs within the monitoring fishing frameworks.
