Understanding human behavior is critical for sustainable resource use. Using interviews with fishing communities as a motivation for our inquiry, we employ an Agent-Based Model to explore incentives for cooperation by information sharing, and how they are affected by management action and resource depletion. Results show that this impact varies between communities depending on the life history of their target species, but also between individuals in the same community. Indeed, resource use under uncertainty leads to heterogeneous performance, even among agents with equal means. As a result, we show they may differ in their preference for communication over independence, but also in their response to a catch share management approach. These findings assume that agent behavior is tuned to optimize a cost-benefit ratio, but we further discuss how they may be affected by other motivations that were reported by fishermen, such as prosociality and predictability of the fleet's output.
