Determination of macro fauna which using a water intake unit of a marine aquarium as a reef in the Gulf of Antalya

ABSTRACT M.Sc. Thesis DETERMINATION OF MACRO FAUNA WHICH USING A WATER INTAKE UNIT OF A MARINE AQUARIUM AS A REEF IN THE GULF OF ANTALYA Kemal GÖKOĞLU Isparta University of Applied Sciences The Institute of Graduate Education Fisheriesand Fish Processing Technology Department Supervisor: Asst. Prof. Dr. Mete KUŞAT This research was carried out in the water intake unit of a marine aquarium which was established next to the Konyaaltı beach of Antalya Gulf. The aim of this study was to determine the macro fauna which uses this water intake as a reef. In our study, Pennaria disticha from hydroid, Spirastrella cunctatrix, Crambe crambe and Irsinia spp. from sponges, Hermodice carunculata, Serpula vermicularis from polychaeta, Synaptula reciprocans, Arbacia lixula and Diadema setosum from Echinodermata, Phallusia nigra, Microcosmus sulcatus and Pyura momus from the tunicates, Charybdis hellerii, Percnon gibbesi, Portunus pelagicus, Balanus sp. and Scyllarides latus from Crustacea, Pinctada radiata, Spondylus spinosimus, Chama pacifica, Saccostrea cucullata, Saccostrea commercialis, Dendrostrea frons, Malvufundus regulus, Ostrea edulis and Arca noae from bivalvia, Hexaplex trunculus, Cerithium sp., Conomurex persicus, Ergalatax obscura, Flabellina rubrolineata, Flabellina sp. Hypselodoris picta from gastropoda species, Trionyx triunguis Nile turtle, Caretta caretta and Chelonia mydas from sea turtles and octopus (Octopus vulgaris), squid (Loligo vulgaris) and cuttlefish (Sepia oficinalis) from cephalopods were determined that they use the unit of water intake as an artificial reef. It was determined that 75 fish species belonging to 28 families used the unit of water intake as artificial reefs. Of these fish species, 23 are Lesepsian fish species of Red Sea origin. In the calculation of biodiversity indices of fish; The Shannon-Wiener diversity index (H ') was used and this value was found to be H = 2.852987835. The Berger-Parker index (d) was used for dominance and the most dominant species was Striped Cardinal fish (Cheilodipterusnovem striatus) determined as d = 0.30981334 (% F = 30.981). Silverfish (Atherina boyeri) with a value of 0.06010379 (% F = 6.010) followed by Melanur fish (Oblada melanura) with a value of 0.05971652 (% F = 5.971).In this study, Upeneus tragu was determined as specie found in and around the unit of water intake and having the least amount individual is 1 (% F = 0.00387) Keywords: Artifical reef, Echinodermata, Crustacea, water intake unit 2019, 84 pages
