Fish spawning aggregations (FSAs) are simply large groupings of fishes that form for the sole purpose of reproduction. Yet these aggregations, which usually occur at specific sites for just a few days or weeks each year, are critically important to the persistence of many fish populations as they may represent 100% of their annual reproduction. The temporal and spatial predictability of FSAs and the large numbers of fish they include make them major targets for fisheries and large sources of income for local communities.
