In this research, the composition and feeding intensity of the black scorpionfish, Scorpaena porcus (Linneaus, 1758) in the Medulin Bay, on the south and southwest side of the islet Bodulaš, was investigated. The content of the digestive tract was analyzed on 163 individuals whose total length (TL) varied from 12.4 to 27.2 cm, collected by the method of "poponica" mesh, different mesh sizes of 32 mm and 40 mm.The feeding intensity of the black scorpionfish in the Medulin Bay is lowest in the summer, ie during spawning. In the Medulin Bay, the main prey of the black scorpionfish are crustaceans from the order Decapoda, while fish prey is eaten less. Of the order Decapoda, according to all indices, the most important is the species Liocarcinus corrugatus. In the spring, crabs of harder shells are present in the diet, while in autumn, shrimps (crabs of softer shells) predominate. The age of the caught black scorpionfish varies from 2 to 10 years. The sex ratio of males to females was 1: 17.1. The age of the black scorpionfish is less closely related to the prey species, but soft-shelled prey was more often consumed by younger specimens, while hard-shelled prey was more often consumed by older specimens. In addition, fish was more present in the stomachs of younger individuals.
