The data on rare fish in the Balearic Islands has been updated this summer to 107 species. The DAPERA (Dades de Peixos Rars) list, which was last published in 2015 and consisted of 97 different marine species, includes ten more in its 2023 update. Of these, population monitoring is of interest, essentially for reasons of vulnerability and conservation. In addition, another list of 48 species has been drawn up, which includes new arrivals. Most of the latter are thermophilic, indicating rising water temperatures, while others are very rare and are expected to occur.<\/p>\n
A total of 281 records of 48 different species have been recorded up to 2022, including 71 records provided by the Observers of the Sea platform up to 2021. Of the species belonging to the vulnerable group, the most cited has been the manta ray (Gymnura altavela), with 32 observations, while some rarer species, such as the cardinal fish, Zu cristatus, or the girdle Trachipterus trachypterus, have only been cited once. As for the species of the newcomers group, the most frequent were the green parrotfish (Sparisoma cretense), the dentex horse mackerel (Pseudocaranx dentex), the royal sardinian (Diplodus cervinus) and the trumpetfish (Fistularia commersonii).<\/p>\n
According to the conservation reference categories established by the IUCN, 2% of the species cited in DAPERA are critically endangered, 5% are endangered, 33% are vulnerable, 34% are near threatened and 18% are species of least concern.<\/p>\n\n\t\t
