Türkiye’nin Ege Denizi’nden Yakalanan Kupes (Boops boops) Balıklarında Hysterothylacium Larvalarının İdentifikasyonu ve Moleküler Karakterizasyonu

Abstract

Hysterothylacium species are the most prevalent ascaridoid nematode reported from various freshwater, estuarial and marine fish species. However, there are very few studies about molecular identification and characterization of Hysterothylacium species in marine fish species from Turkish waters. The aim of the present study was to molecular identification and characterization of Hysterothylacium larvae from Boops boops caught off Aegean Sea, Turkey. Hysterothylacium larvae were found in 10 of 109 B. boops. The prevalence of Hysterothylacium spp. larvae was 9.2%. A total of 10 larvae of Hysterothylacium spp. were collected from all infected fish. Hysterothylacium larvae were genetically identified as H. aduncum, H. fabri and H. reliquens from Turkish waters by using sequence analyses of rDNA ITS regions in B. boops for the first time. In addition, B. boops was reported as a new host for H. reliquens. Moreover, H. reliquens was characterized for the first time by sequencing of the ITS regions from the Turkish waters with the present study. Keywords

Stock discrimination of the bogue, Boops boops (Actinopterygii: Perciformes: Sparidae), from two Tunisian marine stations using the otolith shape

“…This species has a wide geographical distribution that extends from the eastern Atlantic Ocean to the Black and Mediterranean Seas, including Tunisian waters (Amira et al 2019). In addition, this species is demersal, as well as semi-pelagic, gregarious, and lives on all types of the bottom substrata, including mud, rock, sand, and seagrass beds (Simsek et al 2018). However, it is commonly found at depths between 50 and 350 m and in coastal waters, it sometimes moves in aggregations, ascending mainly to the surface at night (Ider et al 2017).…”
