Prevalence and intensity of parasitic helminths of thicklip grey mullet Chelon labrosus in hosts in Beymelek Lagoon Lake in Antalya, Turkey, according to season, host size, age, and sex of the host

摘要: In this study, helminth parasites of the thicklip grey mullet (Chelon labrosus) in Beymelek Lagoon, Antalya (Turkey) were studied to determine effect seasonal changes and host size, age, sex on incidence parasitic infection. Three species identified: Ligophorus angustus Euzet Suriano 1977 (Monogenea) gills, Saccocoelium obesum Looss, (Digenea) Neoechinorhynchus agilis (Rudolphi, 1819) (Acanthocephala) intestine. Among these species, S. Obesum was most common with an overall prevalence mean intensity 42.7% 13.6 ± 12.5 parasites/fish, respectively. L. Angustus second prevalent parasite, 21.3%. The third parasite N. Agilis, 12.6% 3.6 2.1 Regarding changes, highest summer spring, For Angustus, while observed winter (40.6%), not recorded summer. Agilis rather low (41.6%) also detected With regard size-related incidence, differences abundance 3 among 4 size classes significant (P > 0.05). contrast, there age groups = 0.33). As for infrapopulations depending host's sex, found between sexes < 0.001 P 0. 007, respectively).
