The histology and histochemical aspects of gills of the flower fish, Pseudophoxinus antalyae.

Branchial epithelium of Pseudophoxinus antalyae was lined by both a thick stratified epithelium lining gill arches, gill rakers and primary filaments and a thin epithelium lining the lamellae. Mucous, chloride and rodlet cells, interspersed between pavement cells, were present in the branchial epithelium. With histochemical procedures for the characterization of glycoconjugates, mucous cells showed a strong positive reaction with Periodic acid-Shiff and Alcian Blue at pH 2.5, although with Alcian Blue at pH 0.5 and pH 1.0 the reaction was much weaker. When the combined Alcian Blue (pH 2.5) – Periodic acid-Shiff reaction was performed, most mucous cells were stained purple, whereas by the combined Aldehyde Fuchsin/Alcian Blue (pH 2.5), most cells showed a positive reaction only to Aldehyde Fuchsin. Methylation/ Alcian Blue (pH 2.5) and Methylation/ Saponification/ Alcian Blue (pH 2.5) methods showed the presence of sulphated and carboxylated glycoconjugates in mucous cells. Mucous cells were also detected to stain all metachromatically with Toluidine Blue.

Age and growth of Capoeta erhani (Actinopterygii: Cypriniformes: Cyprinidae) from the Menzelet Reservoir, Turkey

Age information is the most important biological variable for estimating growth rates of fishes (Homauni et al. 2011). Determination of the age and growth parameters of fish populations is a very important issue for fisheries management. Fish age is usually estimated using the periodicity of the formation of increments in scales, otoliths, fin rays, and vertebrae (Campana 2001). Otoliths, however, are the structures that are the most preferred by fisheries scientists because of the precision of age estimates (Maceina and Sammons 2006, Čikeš Keč and Zorica 2013). The genus Capoeta Valenciennes, 1842 is distributed in southern China, northern India, Turkmenistan, Lake Aral, the Middle East, and Anatolia. These fishes inhabit gravel and stony zones of fast flowing rivers (Türkmen et al. 2002), but some species may also be found in lakes and springs (Turan et al. 2008). In the inland waters of Turkey there are five species and six subspecies of the genus Capoeta (see Türkmen et al. 2002, Elp and Sen 2009). Capoeta erhani Turan, Kottelat et Ekmekçi, 2008 was described from the Ceyhan River, Turkey (Turan et al. 2008). This species has an economic importance in commercial and recreational fisheries for the local people around the ACTA ICHTHYOLOGICA ET PISCATORIA (2014) 44 (2): 105–110 DOI: 10.3750/AIP2014.44.2.03

Acanthocephala From Seven Species of Freshwater Fish (Cyprinidae and Cyprinodontidae) From Turkey with the Description of a New Species of Paralongicollum (Pomphorhynchidae)

ABSTRACT: 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.

Two new Dactylogyrus species (Monogenea: Dactylogyridae) D. angorae and D. turcicus from Capoeta angorae and C. mauricii endemic fishes in Turkey.

Two new Dactylogyrus spp., D. angorae and D. turcicus have been described from the gills of the endemic cyprinid fishes, Capoeta angorae and C. mauricii from the Anatolian Region of Turkey. The shape of the anchors, hooks and the copulation organ of both species differ from those of the Dactylogyrus spp. found on other Capoeta species known from the Ponto-Caspian and Tigris-Euphrates regions.
