New fish migrations into the Panama Canal increase likelihood of interoceanic invasions in the Americas

Gustavo A. Castellanos-Galindo; Diana M.T. Sharpe; D. Ross Robertson; Victor Bravo; Jonathan M. Jeschke; Mark E. Torchin

The authors have compared the fish communities of Lake Gatun in the Panama Canal before and after the canal’s expansion in 2016: Marine fish species  now make up 76 percent of the total biomass of the fish population and are primarily large predatory fishes. The lake’s food web is changing and local fisheries are impacted. There is also an increased risk of fishes colonizing the opposite ocean.

Combining expert knowledge with literature analysis, this study developed a conceptual classification scheme of invasion science that allows to organize publications and data sets, guide future research, and identify knowledge gaps. The scheme features 5 major themes of invasion science that are divided into 10 broader research questions and linked to 39 major hypotheses of the field.
