Impact DescriptionHoplosternum littorale was found in the stomachs of predatory fish, such as Largemouth Bass (Micropterus salmoides) and Common Snook (Centropomus undecimalis), and made up a significant (near 30-50%) amount of the stomach contents in some seasons, and less of the contents in the spring time, varying with the water body.
