Pseudorasbora parva (Temminck & Schlegel, 1846): a new threat to fish biodiversity in Ordu Province (Middle Black Sea Region).

Abstract

The invasive fish species pose a significant threat to both local fish species and aquatic habitats. During the field surveys, an invasive fish species Pseudorasbora parva was found for the first time in Ulugöl (Ordu). In the field studies, 41 P. parva individuals from different size groups were captured. Total length (TL), fork length (FL), standard length (SL) and weight (W) of this invasive species which continuously increase distribution in Turkish inland waters were recorded. The average TL, FL, SL and W values of the P. parva were 7.24±1.2 cm (3.8-9.4 cm), 6.52±1.1 cm (3.4-8.4 cm), 5.73±0.9 cm (3.0-7.1 cm) and 3.24±1.4 g (0.4415-6.8632 g), respectively. P. parva species was reported as the first record in Ordu (Middle Black Sea Region). The increase in the number of P. parva individuals in Ulugöl is a great threat to Ordu fish biodiversity.
