On the 12th to 18th of September 2019, “Marine and Environmental Research (MER) Lab” revisited the Marine Protected Area of Cape Greco and completed the final ecological monitoring sampling survey for the year 2019. The ecological monitoring survey included fish (including lionfish) counts through Underwater Visual Censuses (UVC) in accordance with the protocol specified. Photos of quadrats were also taken to assess the sessile fauna and flora coverage. Lionfish removals were conducted at some of the surveyed sites, capturing 17 lionfish in total. All survey data were given to the “University of Plymouth” for analysis.
