Abstract

Plavi rak (Callinectes sapidus Rathbun, 1896) je vrsta koja potječe iz zapadnog Atlantika, rasprostranjena diljem europskih obala. Smatra se invazivnom vrstom, visokog reproduktivnog potencijala i izuzetne sposobnosti širenja populacije. Njegove biološke značajke izražavaju se mogućim negativnim utjecajem na okoliš i biološku raznolikost raznih lokaliteta, te ugrožavanjem flore i faune istog staništa. Temeljem dosadašnjih znanstvenih istraživanja, ovaj rad prikazuje podatke o distribuciji, procjeni brojnosti, strukturi i biometrijskim karakteristikama populacije plavog raka, kao i statusu invazivnosti europskih obala, s posebnim osvrtom na Jadransko more. Suzbijanje invazivnosti i otklanjanje daljnje opasnosti za bioraznolikost temelji se na preporukama za stalnim monitoringom i izlovom, korištenjem filtera na brodovima prilikom izmjene balastnih voda, te stalnim praćenjem brojnosti.

Abstract (english)

The blue crab (Callinectes sapidus Rathbun, 1896) is a species originally from the Western Atlantic, spreaded throughout the European coasts. It is considered an invasive species, with high reproductive potential and exceptional ability to spread the population. Its biological features are expressed by a possible negative impact on the environment and biological diversity of various localities, and by endangering the flora and fauna of the same habitat. Based on previous scientific research, this thesis presents data on distribution, abundance estimation, structure and biometric characteristics of the blue crab population, as well as the invasiveness status of European coasts, with special reference to the Adriatic Sea. Suppression of invasiveness and elimination of further threats to biodiversity is based on recommendations for constant monitoring and fishing, usage of filters on ships when changing ballast water, and constant abundance monitoring.
