In Tanjung Tembaga, Mayangan District, Probolinggo City, this study examines traditional fishermen's interest in adopting floating net cage (FNC) technology for marine aquaculture and how their knowledge, economic conditions, and social factors influence it. Data were obtained from 130 respondents selected purposively. The data were analyzed using multiple linear regression with SPSS version 27, following the quantitative descriptive technique established in the Ecosystem Approach to Fisheries Management (EAFM). Although economic factors did not have a positive and significant effect on interest in FNC adoption, knowledge and social conditions did (t = 3.853; Sig. = 0.000 and t = 3.351; Sig. = 0.001). The R² value of 0.357 proves that these three factors influence the interest variable by 35.7%. The results of this study indicate that interest prior to adoption is more influenced by understanding of fishing regulations, high-value species, community dynamics, and local knowledge than by financial status or asset ownership. To help traditional fishermen transition to sustainable marine aquaculture, this study recommends focusing less on financial assistance and more on enhancing technical knowledge, community engagement, and conflict management.
