Seven species of endemic freshwater fish, Aphanius anatoliae, Aphanius villwocki (Cyprinodontidae), Capoeta angorae, Capoeta erhani, Capoeta mauricii, Chondrostoma fahirae, and Pseudophoxinus fahrettini (Cyprinidae) from Turkey were examined for acanthocephalans. Acanthocephalus sp., Neoechinorhynchus zabensis, Pomphorhynchus spindletruncatus, and Paralongicollum nurtenae n. sp. were found. The new species can be distinguished from its congeners by a suite of characters including the shape of the proboscis, which has an armature of 16-22 rows of 10-13 hooks, the posterior most circle of hooks alternating. All are new host and locality records. The geographic distributions of N. zabensis and P. spindletruncatus in Turkey may be due in part to changes in glacial river system connections that have occurred since the Pleistocene.
Pomphorhynchidae and quadrigyridae (Acanthocephala), including a new genus and species (Pallisentinae), from freshwater fishes, cobitidae and cyprinodontidae, in Turkey
(Folia Parasitologica, 2012-09) Smales, Lesley R.; Emre, Yılmaz; Aydoğdu, Ali; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; 6701819349
During a survey of freshwater fishes from Turkey two species of Acanthocephala, one of them new, were found. Pomphorhynchus tereticollis (Pomphorhynchidae) is reported at 24% prevalence in 37 Cobitis bilseli (Cobitidae) from Lake Beysehir, Konya, for the first time. The eoacanthoacaphalan Triaspiron aphanii gen. n. et sp. n. (Quadrigyridae), at a prevalence of 90%, is described from 29 Aphanius mento (Cyprinodontidae), from Kirkgoz Springs, Antalya. The new genus most closely resembles Raosentis Datta, 1947, both having a small spindle shaped trunk, and Acanthogyrus Thapar, 1927, both having a proboscis armature of three circles of hooks. Triaspiron differs from Raosentis in proboscis shape, cylindrical not globular, proboscis armature, three circles, a total of 16 hooks in all, not four circles, a total of 26-30 hooks in all, and trunk spination, two fields of spines in the anterior field with spines arranged in up to 40 circular rows, not a single field with 9-17 rows of spines. Triaspiron differs from Acanthogyrus in having fewer proboscis hooks, 16 compared with 18-24, arranged in three circles, one anterior and two posteriorly placed, with an unarmed region between, not three circles of hooks evenly spaced, and two fields of trunk spines, not one.
Population dynamics of two diplectanid species (Monogenea) parasitising sparid hosts (Sparidae)
(Springer, 2015-03-01) Emre, Yılmaz; Emre, Nesrin; Aydoğdu, Ali; Buselic, Ivana; Smales, Lesley R.; Mladineo, Ivona; AYDOĞDU, ALİ; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu; 0000-0003-2778-0273; JCO-3521-2023
Economically important sparid fish species, gilthead (Sparus aurata) and white seabream (Diplodus sargus) (Sparidae) are frequently parasitised by diplectanid monogeneans, known to induce severe losses in farming conditions. We have analysed population dynamic of two diplectanid species, Lamellodiscus echeneis and Lamellodiscus ignoratus (Monogenea: Diplectanidae) collected from two bream species in the Beymelek Lagoon (southwest coast of Turkey), comparing it between different host variables (fish size, age and sex) in order to have insight in parasites' ecology, important for managing parasitosis in the intensive aquaculture system. In seabream (N = 127), L. echeneis prevalence was 46.5 % (exact 95 % confidence limits 38.90-54.14), mean abundance 5.64 (bootstrap 95 % confidence limits 4.20-7.65) and mean intensity 12.14 (bootstrap 95 % confidence limits 9.49-15.59). In white seabream (N = 102), L. ignoratus prevalence was 24.5 % (exact 95 % confidence limits 16.53-34.03), mean abundance 1.73 (bootstrap 95 % confidence limits 0.98-3.21) and mean intensity 7.04 (bootstrap 95 % confidence limits 4.60-11.40). Parasites' parameters differed only between seasons in both hosts and between age categories in gilthead, but not in white seabream.
