The survey data was collected as part of the research project “Sustainable fisheries: social relations, identity and joint management of Adriatic fishing resources”, which was financed by the Croatian Science Foundation under the grant number UIP-2020-02-2238. The research examines: fishing practices and the use of fishing tools, fishers’ incomes and socio-economic data, working conditions and labour relations, membership in organisations, trust, values and rule compliance, identity and health. The sample of respondents consists of residents of the Republic of Croatia who, within the last year from the moment of questionnaire completion, were engaged in fishing in the area of the Croatian part of the Adriatic Sea. This included professional fishers (large-scale and small-scale), recreational fishers, and fishers who formed a specific Croatian legislative category of small coastal fishing (MOR), which is closest to the category of subsistence fishers. The database of responses to the questionnaire contains 567 respondents (N=567) with 185 variables. Part of the data was collected face-to-face (N=300; respondent categories: large-scale fishing, small-scale fishing, small coastal fishing (MOR)), and part through an online questionnaire (N=267; respondent categories: recreational fishers, large-scale fishing, small-scale fishing, small coastal fishing (MOR)).
