Kerna (Kirnja), 81 kilogram,( Epinephelus marginatus - Dusky grouper ) cought by Ante and Marketo Bonguardo from Korcula. At this photo, small boy Ratko, who is also good fisherman is checking and hoping when he grows up to be able to get some good catch too.
Jacques Cousteau reportedly said that groupers were the strangest creatures he had come across at sea. The dusky grouper is an extremely large fish with an oval body, big head, wide mouth and protruding lower jaw used to catch its prey. Covered with small scales, the base colour of this sizeable fish varies but is generally a grey-brown colour with mottled pale markings. Indeed, the Latin name, Epinephelus, loosely translates to ‘with clouds on it', referring to these distinctive pale blotches. Males display a conspicuous silver streaked pattern during reproductive activity.
