There are two basic categories of marine fishery in the Republic of Croatia: commercial and non-commercial fishing. There is a large number of recreational fishermen in the area of Biograd na Moru, but recently, the number of professional fishermen has increased. Biograd na Moru is a town and port in northern Dalmatia, located on a small part of the peninsula and the mainland, and in front are Katarina and Planac, two islands that are also active fishing areas. There is not enough information about fisheries in this area. Therefore, through the research for this thesis, fishermen from Biograd na Moru and the surrounding areas were interviewed through a survey questionnaire on the topic of fishing, where the fishermen answered questions about the species caught, total catch, and quantity and how they were caught. The goal of the research was, through interviews with local fishermen, to determine (in the period from 1950 to the present day) whether there have been changes in the amount and/or types of catches, especially in the area of Biograd na Moru. The research was based on the experiences of fishermen and their suggestions for improving fisheries. Fishermen mostly caught sea bream (Sparus aurata), cuttlefish (Sepia officinalis), monkfish (Diplodus vulgaris) and common pandora (Pagellus erythrinus). Sea bass (Dicentrarchus labrax) and sand steenbras (Lithognathus mormyrus) are two types of fish that are rarely seen in the catch today, and in the past, they were much more common in the catches in the area of Biograd na Moru. In the last 20 years, some new species have appeared in the catch, such as lamprey, barracuda, darter and moray eel.
