The monitoring and control operation in the La Palma Marine Reserve of Fishing Interest organized by the Ministry of Agriculture, Fisheries and Food has located garden eels in front of the ‘fajana’ created by the volcanic eruption off the coast of Tazacorte, as well as sightings of fish like roosters and old women.

Last Wednesday filming of the Guirres beachfront began with a light ROV (remote operated vehicle), with a high 4K resolution, with 8 motors, stabilizers and a double set of LED lights, which allows obtaining high quality images .

From the ministry they highlight in a note all the roughness of this lava front that shows the reaction of the lava when it reaches the sea and its evolution on that bottom, which contains underwater canyons through which part of that lava flows, as well as the creation in those volcanic tube bottoms.

Likewise, monitoring of hydrography with a probe is carried out and it will begin with sampling bottles (with rosette), visual censuses of fish with dives and underwater filming with ROV.

The General Directorate of Sustainable Fishing is part of the Scientific Committee of the Volcanic Emergency Plan of the Canary Islands (Pevolca), to which it will contribute these images, as well as the hydrographic data and the state of the habitats.

Carrying out continuous monitoring is one of the essential pillars in the management of a marine reserve of fishing interest such as that of the island of La Palma, which has been in existence for 20 years, and has information on the fishing resource and the vessels of the brotherhoods that fish in the reserve, those of Tazacorte and Santa Cruz de La Palma.

The ministry has an operation and monitoring service, as well as guards, for the La Palma marine reserve, which permanently monitors the reserve and its surroundings.

TWO BOATS AND A ROBOT

The service is made up of a biologist, the Ignacio Aldecoa and Roque del Águila vessels, as well as probes, autonomous diving equipment and underwater robots (ROV).

The continuous presence of means of the General Secretariat of Fisheries in the reserve and in the surrounding areas to be able to compare in time and space the protected zone of the zone outside it is essential to detect the ‘reserve effect’ and allow a adaptive management in full collaboration with the fishing sector and according to the best scientific information.

Faced with the volcanic crisis, these monitoring of the reserve, inside and outside the reserve, over time, with historical series of years, are of special importance.

Thus, having historical data from the area is essential to document this evolution, as occurred in the monitoring of the Tagoro submarine volcano that emerged, now 10 years ago, half a mile from the Punta de La Restinga-Mar de Las Calmas marine reserve. .

The General Secretariat for Fisheries adds to the local fishing benefits of the La Palma marine reserve, the provision of information of general interest to monitor the evolution of the seabed, the water column, habitats and biodiversity with special emphasis on the fishing resource, by having series not only from the reserve, but outside.

In this case, the evolution of the runoff in the sea and the formed lava delta can be observed giving information on an extraordinary phenomenon of great importance, the eruption of Cumbre Vieja, which had not occurred for 50 years and with trained human resources. and equipment
of the XXI century.
