There is still a very active "discovery component" to work on spawning aggregations. Quite a few species, presently not known to form spawning aggregations, may eventually be found to have them, while many aggregations remain undiscovered. Discovering the unknown is never easy, especially when you are seeking a group of fish in 30 m of water somewhere along a hundred km of shelf edge that exists only for a short period each year. Consequently, scientists and managers need to use every resource available to increase the probability of success in finding spawning aggregations. Finding a previously unknown aggregation site is exciting and may provide valuable information but carries with it the responsibility to be careful about revealing its location prematurely to avoid its possible abuse.
