Understanding Fisher Behavior: The Case of Snapper Fishers in Indonesia

Abstract

It is important to incorporate fisher motivations and behavior into fisheries management models. Incorrect behavioral assumptions may yield ineffective incentives or interventions or even produce unintended consequences. To understand fisher behavior in a developing country, we surveyed 93 Indonesian snapper fishers. Results suggest they consider competing aspects such as income, personal reputation, and sociocultural norms when deciding where and what to fish; they update beliefs about location, bountifulness, and catchability of target fish stocks through direct observations, inferences over geographical similarities, and social interactions with other fishers, and they evaluate satisfaction economically as well as socially. Information sharing and social knowledge are likely port-specific, representing local sociocultural norms rather than being related to vessel size, target catch, or other demographics. The prevalence of information sharing and imitation patterns suggests that fisher decision-making in Indonesian snapper fisheries has a significant sociocultural component. We discuss implications for fisheries management models and for policy decisions.
