Summary The length–weight relationship parameters and seasonal reproductive cycle are recorded for six commercially important fish species caught in the coastal lagoon of Tres Palos. The length–weight information is new to the literature for three of these species (spot cichlid, spotted sleeper, Pacific fat sleeper) and is within the expected range for the other three (widehead sea catfish, three spot cichlid, white mullet). Differences between sexes are statistically significant for four species and deviations from isometric growth are indicated in three species. The reproductive period for the Pacific fat sleeper differed substantially from the period reported for this species in Ecuadorian waters.
