Portugal’s first guide to freshwater fish and migrant biodiversity

The first guide for freshwater fish and migrants from mainland Portugal was recently published by Edições Afrontamento, who has now informed the National Museum of Natural History and Science (Muhnac) of the University of Lisbon.

It is a 292-page guide resulting from a project coordinated by Maria João Collares-Pereira of the Faculty of Natural Sciences of the University of Lisbon (FCUL) that describes all known native, migratory and marine visitor species to date, ”announced the museum in a statement.

The book also describes the “exotic species found in national rivers and reservoirs”, including maps of their distribution in the country, in a total of “62 species”, accompanied by scientific illustrations in the form of original watercolors by Cláudia Baeta and Pedro Salgado.

“It is a tool of great practical and scientific value for those interested in the subjects covered, including recreational and sport fishermen, environmental technicians and managers, teachers and students, and the general public,” said the research coordinator.

The guide was co-authored with other national researchers, namely Maria Judite Alves, Filipe Ribeiro, Isabel Domingos, Pedro Raposo de Almeida, Luís da Costa, Hugo Gante, Ana Filipa Filipe, Maria Ana Boim, Patrícia Marta Rodrigues and Maria de Filomena Magalhães.

It is published at a time when “the deteriorating pressure on river ecosystems” in the country and throughout the Mediterranean, “due to habitat destruction, the introduction of exotic species and climate change, among other things,” “requires the mobilization of” everything ” , it says in the communiqué.

The guide looks at “from the different types of river ecosystems to the particular characteristics of the fish that inhabit them”, but also “the value they have in a scientific, historical, decorative and cultural context”.

“Some species such as the lamprey, the shadow, the European eel and the largemouth bass are known to the public, but many other species such as the barbel, bog and scales that live in our rivers are virtually unknown to humans. The value of these species is incalculable, since in many cases they are exclusively reserved for the Iberian or national rivers, which increases the importance of their distribution also from the point of view of protection, ”emphasized Maria João Collares-Pereira, quoted in the statement.

The guide was supported by the Foundation for Science and Technology through the Center for Ecology, Evolution and Environmental Change (CE3c). do Mare – FCUL Center for Marine and Environmental Sciences; from Muhnac and from the University of Évora; Biota – Environmental Studies and Dissemination; and the Lisbon City Council.
