Analysis of the spatial and seasonal variation in catchability of red grouper, Epinephelus morio (Valenciennes, 1828), in the Campeche Bank before overfishing (1973-1977)

The red grouper Epinephelus morio fishery in the Campeche Bank, northern coast of the Yucatan Peninsula, is overfished. The main causes are high fishing pressure in areas of reproductive aggregation and juvenile nursery zones. An analysis of the spatial-seasonal variation in catchability was underta...

An analysis of the spatial-seasonal variation in catchability was undertaken using data from 1973 to 1977, with the aim to detect areas of higher vulnerability to fishing, taking into account the red grouper developmental stages (juvenile, pre-adults, and adults).
