Ecological Risk Screening Summary - Onesided Livebearer (Jenynsia lineata; a fish)) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

J. lineata has a medium climate match for the contiguous U.S. with highest matches across the East Coast and bordering the Gulf of Mexico. This species, however, has little history of movement and no documented introductions. Therefore, history of invasiveness is uncertain. More information is required to adequately assess the risk of this species, leading to a low certainty for this assessment. The overall risk of J. lineata to the United States is uncertain.
