Understanding the factors driving fish behavior, physiology, and survival is increasingly important during this period of unprecedented global change, given their implications for fisheries stability ecosystem health.

Quantifying habitat needs across all life stages (and predators prey) challenging, however, relies on diverse approaches such as field observations, laboratory experiments, genomics, chemical tracers, telemetry, modeling.
