Hi all,
I am part of the grouper and wrasses IUCN specialist group, and we are always searching for pictures or video (and new locations) of grouper spawning aggregations. If you are curious about spawning aggregations, check out this link:

If you think you have photos and/or video of spawning aggregations, contact me! Spawning aggregations are the target of fishermen, and this is a serious threat for many grouper species.
