Abstract
Cichlasonza heterospilurn, a potentially important species for aquaculture was studied in the southern Gulf of Mexico. The sex ratio was 1:1, and there were seasonal differences in abundance of mature individuals. Parameters of the von Bertalanffy growth equation were K = 0.38 (year1), 26 cm (TL), W∞ = 321 g, to = 0.249 years. This omnivore has a daily food consumption per .unit biomass of Q/B = 4.05% of body weight, annual Q/B = 14.8%; however, gross efficiency of growth associated to food consumption can be assumed to be relatively low ( = 0.1147) compared to other commercially important species. Aquaculture would require an increase in growth efficiency.
