Fish can be picky eaters

The community of coral reef biologists, fishers and reef managers have always known that fish can be specific in what they eat. But with new technology we are learning just how specific they can be. And that specificity can translate into roles on the reef that contribute in a targeted way to the functioning and resilience to the reef. E-DNA and metabarcoding is allowing us to tell new and important stories about these ecosystems and translate that into conservation and management.
