Hybrid carp from the cross grass carp Ctenopharyngodon idella ♀ X bighead carp Aristichthys nobilis ♂ preferred filamentous algae and Najas guadalupensis over Ceratophyllum demersum. Medium‐sized (273 g) and large hybrids (360 g) consumed more plant material and grew faster than small hybrids (77 g) at 14 and 22 C in aquaria. Aquarium data suggest that it will require at least twice as many hybrids as grass carp of the same size to obtain the same level of vegetation control.
