Abstract. The fleet dynamics of capture fisheries involves changes in fishermen’s behavior in the form of increased efforts to obtain catches. This approach has been implicated in increased fishing pressure on the coastal areas, and has instigated an upsurge in the potential to create ecological, economic, and social vulnerabilities. Therefore, it is necessary to know the factors that affect the number of small-scale fishing trips in the Kei Islands spatially and temporally. This study aims to analyze the factors that influence the number of small-scale fishing trips in the Kei Islands. Furthermore, the research methods adopted include a survey with a purposive sampling technique, while descriptive comparative and multiple linear regressions were used for data analysis. The results show that the number of fishing trips determines the dynamics of small-scale fishing fleets. Factors affecting on fishing trips to catch lift nets, purse seine, troll line, hand-line, bottom gillnet, and drift gillnet fishing fleets include catch yield, fleet income, operational costs, rainfall, wind speed, individual capacity and fishing ground. In addition, increasing the number of fishing trips to maximize catches and income both spatially and temporally is assumed to facilitate the reduction of fish resources. Therefore, business sustainability from an economic and biological perspective requires the application of an appropriate management system for input and output control techniques.
