Globally declining fish populations are a frequently cited ecological and commercial calamity, but relatively little attention has been paid to the specific threats faced by fish that gather and spawn in large groups. Because they gather in such large groups, these fish are at particular risk of overfishing and population collapse. In this episode of BioScience Talks, we're joined by Yvonne Sadovy, of the University of Hong Kong and Science and Conservation of Fish Aggregations (SCRFA), who studies these aggregate spawners. In our discussion, she outlines the unique threats faced by these species, which also include ineffective management techniques better suited toward fish with different life histories. She also outlines the mechanisms that might help preserve these aggregations in the years to come.
