Randomized trial shows habitat quality influences fish communities under illegal fishing pressure, indicating a need for enforcement.

This research aims to understand how fishing pressure affects fish communities in relation to habitat quality on coral reefs.
Utilized coastal surveillance radar systems (CSRS) to monitor illegal fishing activity.
Conducted underwater visual surveys of fish biomass, abundance, and richness.
Analyzed data using generalized additive models (GAMs) to explore interactions between fishing pressure and habitat complexity.
At low coral cover (<20%), fish biomass and abundance declined sharply with increased boat density (β ≈ -0.30).
At high coral cover (>50%), fish community metrics remained stable despite fishing pressure.
Shift in community composition showed declines in large-bodied predators and herbivores, highlighting enforcement needs.

Wen et al. (2026) studied this question.
