Fishes previously referred to subspecies gobio be¬long at least 8 species. Among them, two new species described: G. battalgilae northern Beyşehir Lake system (a Central Anatolian endorheic basin) maeandricus headwaters Great Menderes River (Aegean Sea basin). These spe¬cies distinguished by a combination number lateral...

Abstract In Georgia, crucian carp Carassius carassius (Linnaeus, 1758) was known from only one locality after Kessler’s record (1877–1878) with no new findings until 1985. Since then C. rapidly and simultaneously invaded almost all water bodies of Georgia. 2004, it for the first time noted that this invasive sp. could not be a Carassius, but form gibelio (Bloch, 1792). However further data is available about species in The aim present study to investigate taxonomic status Georgia using mtDNA...

The genus Chondrostoma (Leuciscidae: Leuciscinae), composed of small to medium-sized fish with a scraper feeding characteristic, is distributed in the West and Middle East, Caucasus, Europe Northern Mediterranean drainages. This spreads across Anatolia Thrace, exception Göksu Eşen rivers Turkey’s basin. It also difficult understand systematics , which complicated morphologically. Therefore, this study, an identification key was made by evaluating external morphology, osteology (some jaw...

Invasive species present a serious peril to aquatic ecosystems worldwide, thus it is essential have comprehensive understanding of the reproductive dynamics, spreading characteristics, and biological properties these in order effectively manage their population structure mitigate both ecological damage economic loss they can cause. For this reason, we delved into dynamics Pseudorasbora parva, an invasive inland water fish found Türkiye. We focused on three populations inhabiting Beyşehir...
