During these two weeks we have the pleasure to share our laboratory with the recognized professor Dr. Marcelo Oliva. The collaboration is framed between Dr. Marcelo Oliva, Deputy Researcher at the Millennium Institute of Oceanography of the University of Concepción, professor at the University of Antofagasta and director of the PhD Program in Applied Sciences with a mention in Coastal Marine Systems, and Dr. Pablo Presa, leader of Marine Genetic Resources group from the the University of Vigo.

During his stay at the University of Vigo, Marcelo Oliva presented  part of his work on ecology and evolution of marine parasites, which he uses as a tool for the identification of fishing stocks and the monitoring of migratory movements, in the Marine Research Center-ECIMAT. In particular, Dr. Oliva expounded two papers «Parasites of marine fish on the last frontier> 1500 m depth» and «Merluzas de América del Sur: paths of colonization inferred from their metazoal parasites», in which he talked about his research work with metazoan fish parasites of Depth in the north of Chile, in which he uses the by-catch of the artisanal fishing vessel of deep-sea-bed Dissostichus eleginoides as a source of biological material.

The works presented are framed within the «Deep Ocean» Research line in which the role of deep-sea fish parasites is evaluated as «biological marks» of connectivity in the Deep Ocean. This line of research, developed by the Millennium Institute of Oceanography, is led by Dr. Rubén Escribano of the University of Concepción, in collaboration with Luis A. Ñacari (Peru), Juan F. Espinola- Novelo (Mexico), PhD students in Applied Sciences with mention in Coastal Marine Systems (Universidad de Antofagasta and Fabiola Sepúlveda) and Florence Drugs (University of Western Brittany – France).
