On September 4 and 5, at E.S.E.T.P. No. 721 “Caleta Horno” in Camarones, a specialized training session on the Patagonian Red Octopus was held. The main objective of the workshop was to strengthen the technical and theoretical capacities of participants in biological monitoring methodologies, promoting the conservation of the species and the sustainable management of marine ecosystems in the region.
The activity was co-organized by the Forum for the Conservation of the Patagonian Sea and Areas of Influence, through the technical teams of WCS Argentina, the Government of Chubut, through the Ministry of Tourism and Protected Areas, the Secretariat of Fisheries, the National Parks Administration, and CCT CONICET-CENPAT. This initiative is part of the MaRes Project, which aims to strengthen the resilience of Argentina’s marine and coastal protected areas and is supported by the European Union in Argentina.
Twenty-one people participated, including wildlife rangers, park rangers, artisanal fishermen, teachers, students from E.S.E.T.P. No. 721 “Caleta Horno,” and technical staff from the Chubut Secretariat of Fisheries. The workshop was led by Dr. Nicolás Ortiz and Dr. Silvina Van der Molen from the Institute of Marine Organism Biology (Instituto de Biología de Organismos Marinos – IBIOMAR) of CCT CONICET-CENPAT, together with the MaRes Project team.
The training took place in two stages: on the first day, participants attended a theoretical and informative talk, which explored the biological, ecological, and conservation aspects of the Patagonian Red Octopus, as well as the importance of sustained long-term monitoring. On the second day, practical laboratory activities were carried out, focusing on learning the sampling methodology and data collection for the prioritized biological indicator, strengthening the technical skills of wildlife rangers, park rangers, and staff from different institutions.
“It was gratifying to see the great interest of managers and the community in this training. We had the opportunity to learn from the best specialists in the field, who, in addition to their scientific expertise, were able to convey the content in a warm, accessible, and practical way.” Julieta Campagna, researcher at WCS Argentina.
About the Patagonian Red Octopus
The Patagonian Red Octopus (Enteroctopus megalocyathus) is an emblematic artisanal fishery resource in the town of Camarones, where it has been caught since the 1960s exclusively in the intertidal zone. This species, emblematic of the region, is a biological resource of great importance in marine food chains.
The species can reach more than 1 meter in length and exceed 7 kg in weight. Like other cephalopods, it has direct development and a single reproductive event throughout its life. Studies conducted over the last 20 years by the IBIOMAR Cephalopod Laboratory indicate that in the northern and central Patagonian region, the reproductive cycle is highly seasonal and its populations are structured spatially and temporally according to their reproductive stage and the availability of shelters.

“In Camarones and surrounding areas, the population structure of the resource indicates that during the fall and spring fishing seasons, immature and maturing octopuses predominate in the intertidal zone, while in summer, advanced maturing and mature specimens move to deep waters to mate and spawn, decreasing their abundance. This bathymetric migration reduces the availability of octopuses in the intertidal zone and allows most mature specimens to escape the fishery, spatially and temporally modeling the extractive activity. That is why the training focused on acquiring the theoretical and practical knowledge needed to monitor the reproductive status of the specimens that are caught, as this is an indicator that the spatio-temporal dynamics of the resource are behaving as expected.” Dr. Nicolás Ortiz, from the Institute of Marine Organism Biology at CCT CONICET-CENPAT.ía de Organismos Marinos del CCT CONICET- CENPAT.
Participation for conservation
This training is part of the participatory strategy developed during the first two years of the MaRes Project (2023-2024), aimed at designing and consolidating a Biological and Public Use Monitoring Program for the Península Valdés Natural Protected Area (ANPPV) and the Southern Patagonia Interjurisdictional Coastal Marine Park (PIMCPA). More than 40 experts, including representatives from academia, the Chubut government, and the National Parks Administration, participated in workshops, working meetings, and exchanges to define monitoring priorities, indicators, and protocols. This was essential for prioritizing simple, long-term sustainable, and relevant methodologies for assessing the conservation status of species and biological indicators.
The training demonstrates that effective conservation requires not only technical knowledge, but also collaboration between institutions, local communities, and experts. Strengthening the capacities of those who work directly in the monitoring and management of marine ecosystems ensures the continuity of conservation programs and reinforces the shared commitment to protect emblematic species such as the Patagonian Red Octopus, contributing to a more resilient future for the Patagonian oceans.
