Their findings showed that higher abundances of Prussian carp are associated with lower numbers of native fish species, specifically brook stickleback and fathead minnow. Abundance was also determined to be a better predictor of impact than time of invasion. Overall, study authors say their\u00a0results showcase the need for\u00a0better conservation management to prevent further disruptions from the invasive species.<\/p>\n<p><strong>Authors:<\/strong><\/p>\n<p>Jonathan L.
