Confirmed record of clavellotis fallax (heller) (siphonostomatoida lernaeopodidae) from dentex dentex (linnaeus) with morphological characters in Turkey

Abstract

Lernaeopodidae is a diverse and large family of highly specialized parasitic copepods, currently comprising 48 genera (Boxshall and Halsey 2004). Lernaeopodids are found everywhere in theworld's oceans on teleosts and chondrichthyans. As a group, they may infect all external surfaces of the host's body, including the gills, spiracles, and olfactory sacs (Benz 1993). The pathology associated with lernaeopodid copepods depends on the tissueinfected,the parasite species, its size,and the type of bulla (Lester and Hayward 2006). Salmincola edwardsii in brook trout caused a severe diffuse exuberant proliferation of gill epithelium, resulting in severe lamellar fusion and aneurysms (Duston and Cusack 2002).Fifteen species ofthe Lernaeopodidae family are reported from Turkish waters, namelyClavellotis fallax (Heller, 1865), Clavellotis brianiBenmansour, Ben Hassine, Diebakate & Raibaut, 2001; Clavellotisstrumosa(Brian, 1906), Clavella alataBrian, 1909; Clavellisascombri(Kurz, 1877), Lernaeopoda galeiKrøyer, 1837, Thysanote impudica(Nordmann, 1832), Parabrachiella bispinosa(Nordmann, 1832), Parabrachiella exigua(Brian, 1906), Parabrachiella insidiosa(Heller, 1865), Parabrachiella hostilis(Heller, 1868), Tracheliastes polycolpusNordmann,1832, Naobranchia cygniformisHesse, 1863, Pseudotracheliastes stellifer(Kollar, 1835) (Alaş et al. 2014).The morphological characters in the study obtain a possibility to compare the other countries’findingsnext time. This study aims to confirm the occurrence of C. fallaxwith the morphological characters especially includingmouthparts from Turkey. It also aims to present the host preferences according to family characteristics, habitat selections, feeding habits for C. fallaxLernaeopodidae is a diverse and large family of highly specialized parasitic copepods, currently comprising 48 genera (Boxshall and Halsey 2004).
