WebJan 1, 2011 · A spawning aggregation is a grouping of a single fish species that has gathered at a specific location, at a density that is at least four-times greater than normal, with the specific purpose of reproducing ( Chap. 1 ). To form aggregations, fish may travel very long distances.

WebSpawning aggregation is defined as a group of fish of the same species that are gathered together for the purpose of spawning — releasing sperm or eggs for the purpose of reproduction. The fish population that is together at this time is significantly greater than during periods the fish are not reproducing. WebA fish aggregating (or aggregation) device ( FAD) is a man-made object used to attract ocean -going pelagic fish such as marlin, tuna and mahi-mahi (dolphin fish). They usually consist of buoys or floats tethered to the ocean floor with concrete blocks. FADs attract fish for numerous reasons that vary by species.
