Like many birds and other vertebrates, lots of marine fishes aggregate to breed or feed

  Spawning aggregations are the only time that these marine fishes produce the next generation of fish

  Un-managed fishing on aggregations can quickly deplete fish stocks, reducing their productivity and making the fisheries less resilient; this affects livlihoods and food security, and can even threaten species
