Abstract

Blackmouth catshark Galeus melastomus samples were collected using trawl operations from the deep sea area of the Gulf of Antalya, Turkey, in September and October 2016. The present study aims to clarify the status (prevalence and mean intensity) of endo-parasite infection in blackmouth catshark. All parasite specimens were identified as Grillotia sp. Guiart, 1927 (Grillotidae), Trypanorhyncha cestoda. Total length and weight of uninfectedfish (Nui=33) was 30.95 ± 2.06 cm was 26.86 ± 7.56 g, respectively. Total length and weight of infected fish (Ni=7) was 43.63 ± 6.60 cm, 266.22 ± 130.36 g, respectively. Total number of isolated parasite was 363, prevalence 21.67 ± 11.79% and mean intensity 58.50±20.51. This is the first documented report on the occurrence of Grillotia sp. in blackmouth catshark caught in the Gulf of Antalya, Turkey.
