A juvenile male of porbeagle (Lamna nasus) was caught in waters off Piran (Slovenia, northern Adriatic) on December 22, 2015. The specimen was accurately measured and weighed. Cephalopods and fish remains were found in its stomach contents. This is the first record of a porbeagle in the waters of Slovenia and in the Gulf of Trieste, and one of the few records up to date reported in the northern Adriatic Sea. The presence of this juvenile specimen arises a question whether the Adriatic Sea is a reproductive ground of this species. According to an older record from 1910, a female porbeagle with four embryos was caught on Ugljan Island, confirming the fact that porbeagles reproduced at least in the past in the Adriatic Sea. Nedorasla jedinka mužjaka kučine (Lamna nasus) uhvaćena je u vodama Piranskog zaljeva (Slovenija, sjeverni Jadran) 22. prosinca 2015. Primjerak je izmjeren i izvagan. U sadržaju želuca pronađeni su glavonošci i ostaci riba. Ovo je prvi zapis o kučini u tršćanskom zaljevu, i jedan od rijetkih zapisa prijavljenih u sjevernom Jadranskom moru. Prisutnost ovog nedoraslog mužjaka povlači pitanje da li je područje mrijesta ove vrste Jadransko more. Prema starijem zapisu iz 1910. kod otoka Ugljana je uhvaćena ženka psine kučine s četiri embrija. Time se potvrdila činjenica da se ova vrsta barem u prošlosti razmnožavala u Jadranskom moru.
