This document discusses using video surveys and agent-based modeling to estimate the abundance of reef sharks in the Ningaloo Marine Park. It notes that estimating abundance of elusive species like sharks is challenging. The study aims to minimize biases by using underwater video and modeling to generate density estimates. An agent-based model is used to simulate shark foraging behavior, requiring data on movement lengths and turning angles. A new video campaign using additional cameras will provide more data on turning angles and swimming behavior at different times of day to refine the model. The goal is to obtain accurate abundance estimates for effective shark conservation in the park.
