Abstract Italy, at the center of the Mediterranean Sea, hosts a high diversity of fishes, but to a certain extent, this richness remains hidden or poorly known because of rare, cryptic or recently introduced species, that are hardly to detect with the traditional sampling approaches. In this study, we gained complementary knowledge, engaging Italian sea users, especially fishers and underwater photographers, to share their observations. Results obtained during 2019 provided 124 new records distributed in 40 species. Most of these records are related to native-rare and native-thermophilic fishes (~95%), while few observations (~5%) concern non-indigenous taxa. Records of thermophilic species were reported from the Tyrrhenian Sea and the Ionian Sea, while alien species were mostly reported from the southernmost coasts of Italy. Our findings highlight the potential of participatory actions and emphasize the value of a close collaboration between researchers and sea-lovers for monitoring marine biodiversity on large spatial scales.

意大利海域稀有、外来和被忽视的鱼类快照：一项公民科学调查

摘要 意大利位于地中海的中心，拥有高度多样化的鱼类，但在某种程度上，由于稀有、神秘或最近引入的物种，这种丰富性在一定程度上仍然隐藏或鲜为人知，传统采样很难发现这些物种。方法。在这项研究中，我们获得了补充知识，吸引了意大利海上用户，尤其是渔民和水下摄影师，分享他们的观察结果。2019 年获得的结果提供了分布在 40 个物种中的 124 条新记录。这些记录中的大多数与本地稀有和本地嗜热鱼类 (~95%) 相关，而很少有观察 (~5%) 与非本地类群有关。嗜热物种的记录来自第勒尼安海和爱奥尼亚海，而外来物种主要来自意大利最南端的海岸。
