Ameiureus melas - an invasive species in Țaga Mare Lake, Cluj County, Romania.

Abstract

This paper aims to record the presence of the black bullhead (Ameiurus melas) in Țaga Mare Lake, Cluj County, Romania. In the research, 63 specimens were captured in April-May 2020, by angling techniques. The fish were identified based on the shape of the pectoral spine. The fish has been captured by many sport fishermen in 2020, with some unrecorded reports, in smaller numbers, in 2019. Specimens between 3 and 320 g were captured. Some bigger specimens were dissected and ovaries were visible, suggesting that the species spawns in the lake. Further studies regarding the species in Țaga Mare Lake will be conducted.
