SPAG monitoring conducted for Nassau Grouper (Epinephelus striatus) is monitored from November to February and the Snapper Species (Cubera, Mutton and Dog Snapper) is monitored from March to June at GSSCMR each year. The monitoring of these spawning aggregation sites requires trained data collectors and advance open water divers that conducts two monitoring dives per day during the period of the full moon. Size, type, amount and spawning activities of aggregating fish species are recorded during these monitoring dives. In addition to this, physical condition such as wind direction, current direction and speed, and temperature are recorded to complement the understanding of the spawning activities at the site located in the pelagic region of the Whale Shark Zone.
