What can we do to help control invasive species?
Below is an excerpt from an interview with Hannah Owens.
Transcript of the interview excerpt.
Fish commonly kept in the home aquarium are turning up in waters in the United States, according to the Southeast Fisheries Science Center, SEFSC. Hobby fish, such as lionfish, humpback grouper and clown triggerfish, are now considered invasive in the Southeast United States, according to the SEFSC.
“There’s no way for a reef fish from the Pacific, that’s tropical, to get to the Atlantic, unless somebody’s helping it,” Hannah Owens, a graduate student of ichthyology at the University of Kansas, said.
Studies have shown that lionfish have been introduced into the Gulf of Mexico multiple times, Owens said. A prevailing hypothesis is that somebody had an aquarium that they no longer wanted and dumped it, “it was definitely more than one introduction,” Owens said.
