What can we learn about the ichthyofauna of the Eastern Adriatic Sea from the social network?

In the last decade, social networks became one of the most important tools for communication among people. Numerous interest groups existing on social networks discuss various issues and provide information which might have a value from the scientific standpoint, but are usually overlooked. In this particular case, we were able to collect various ichthyologicaly valuable data based on the fisherman and citizen input in the various fishery related interest groups and personal pages existing on social network. Collected data origins from either professional, sport or recreational fishery activities in the Croatian part of the Adriatic Sea. For example, we acknowledged first presence of juvenile specimens of Sphoeroides pachygaster, additional occurrences of recently established species like Caranx rhonchus and Caranx crysos. Occurrences of previously rare species like Synodus saurus, Balistes carolinensis, Epinephelus aeneus, Xyrichthys novacula etc. It is even possible to observe seasonality of certain fish species by the appearance in catches shared on social network. In this presentation we show some of the most interesting cases which deepen our knowledge on the ichthyofauna of the eastern Adriatic Sea.
