Comparison of catch, CPUE and length distribution of spawning aggregations of mutton snapper (Lutjanus analis) and grey triggerfish (Balistes capriscus) on a Mesoamerican coral reef

ABSTRACT This study evaluates the habitat characteristics, fishing effort, and production, as well as changes in the individuals, such as changes in size frequency, of the spawning aggregations of mutton snapper Lutjanus analis and grey triggerfish Balistes capriscus, caught in the Chinchorro Bank B...
