Penetration of Monrovia Surgeonfish Acanthurus monroviae (Perciformes: Acanthuridae) to the Black Sea

Abstract

The Monrovia Surgeonfish Acanthurus monroviae Steindachner, 1876 is reported for the first time in the Black Sea off the southwestern coast of Crimea (44°29.5ʹN; 33°35.5ʹЕ). The single specimen was caught by the commercial trap net on September 19, 2018; its standard length was 195 mm. The most realistic version of its occurrence is the self-penetration of this specimen into the Black Sea from the Mediterranean Sea. Over the past 20 years, twelve fish species that had not previously been met in the Black Sea were registered near the southwestern coast of Crimea.
