    Confirmed Occurrence of Caligus mugilis Brian (Copepoda, Siphonostomatoida; Caligidae) with Morphological Characters in Turkish Marine Waters
    (Springer International Publishing Ag, 2017) Alas, Ali; Oktener, Ahmet
    The aim of this study is to determine Caligus mugilis including morphological characters on Mugil cephalus from BandA +/- rma Bay in Turkey. The flathead grey mullet, Mugil cephalus were examined for the ectoparasites in 2016. Caligus mugilis Brian, 1935 (Copepoda, Siphonostomatoida, Caligidae) is confirmed for the first time in Turkish marine waters. Also, some morphological characters of this parasitic copepod are described. All parasites were firmly attached to the gill filaments of the host. Parasite prevalence, mean intensity and mean abundance were 9.3%, 1, 0.09, respectively. It should be noted that Caligus mugilis was reported by some researcher in 1989, however there was uncertainty about the occurrence of Caligus mugilis in Turkey. This controversial issue is cleared with this study.
