Impact ID6361
Impact TypeGenetic
Study TypeAnecdotal
Study LocationN/A
Impact DescriptionIn a laboratory setting, rudd (Scardinius erythrophthalmus) readily hybridizes with native golden shiner (Notemigonus crysoleucas), a primary forage species of many native game fishes. First generation hybrids offspring should show heterosis (or hybrid vigor), but the "genetic pollution" in subsequent generations could prove detrimental due to a variety of factors (e.g., spawning behavior, recruitment success, and general loss of fitness).
