This study analyzes some basic aspects of the biological dynamics of lutjanid larvae in the northeastern part of the Colombian Caribbean. They had a wide distribution in the study area, and the highest abundances and indices of occurrence were found at the stations off Riohacha, between 6 and 18 nautical miles from the coast. July, October and May had the highest values, with an average of 12.90, 7.67 and 22.47 larvae/10 m2, respectively; the highest temperatures and lowest salinities were also recorded during these months.
