In collaboration with the Wildlife Service of the Generalitat Valenciana, 1.500 specimens of pseudorasbora parva, a potentially invasive species of the Valencian habitat.

The fish were returned or transferred to other estuaries after fishing and those removed were used as food for otters, mongooses or leopards.

Last December, a selective electrofishing day in the Madagascar estuary to audit your fish population in the presence of a species that could be invasive in the nearest environment. The fundamental objective was to remove the specimens of Pseudorasbora (Pseudosbora parva) that could pose a danger of colonization in the natural environment in the event that a wild bird accidentally transferred eggs of that species outside the park. In addition, the operation was used to carry out a census of the population of individuals in this area.

To carry out this process, we have had the collaboration of the Wildlife Service of the Department of Agriculture, Environment, Climate Change and Rural Development of the Generalitat Valenciana which deployed a team of five professionals and an electric fishing system.

This method of capturing fish uses electrical current to produce a type of paralysis that facilitates collection using nets. It is especially used in cases of sampling fish of small species, multispecies populations and in shallow areas. Its about more efficient sampling system as it allows individuals to be selected and returned in perfect condition.

The cooperation between the technical teams of the Ministry and BIOPARC allowed the work to be carried out in just over an hour. fishing, control and return of different species. As a preventive measure, the 1.500 trapped specimens of between 5 and 10 grams of Pseudorasbora were removed, which, along with large specimens of other species, have been destined to be food for otters, mongooses and leopards. The rest of the fish were returned to the Madagascar estuary or moved to other areas where wetland ecosystems are recreated.

With these actions the need for the cooperation of different institutions in the protection of biodiversity and the importance of maintenance of the balance of species in their habitats, as well as the park's environmental commitment to the nearest natural environment.
