"In 1972, the bleak was accidentally introduced with other fish species from Britain to Cyprus, where it was established and breeding (Lever, 1990)" (Vinyoles et al. 2007).
"In Cyprus, its high fecundity allows the bleak to form dense shoals and outcompete other species (Welcomme, 1988)" in CABI (2023).
