Fishermen of the communities on the banks of the Hondo River have joined in the search for devil fish, to control its invasion and prevent its arrival to Bacalar.

Fishermen use tools such as nets, traps and harpoons to capture the devil fish in the Hondo River, and prevent it from proliferating and reaching Bacalar.

Each of the devil fish captured is measured, weighed and its sex is identified, to be recorded in a database in order to contribute to citizen science and the study of the distribution of this invasive species.

The devil fish could turn the water of Bacalar into a single dirty and cloudy color, affecting not only the fishermen of the Hondo River, but also all those people who make a living from tourism in this region.
