Highighted items on the list are where Dorosoma petenense may be found.
Remarks Found mainly in freshwater (in large rivers, reservoirs (Ref. 10294), lakes, swamps, temporary floodwater pools, etc.), but adults are also found in brackish or saline water of estuaries and bays (up to 30 ppt salinity; juveniles to about 15 ppt) (Ref. 5722). Filter-feeders but not entirely herbivorous; method of feeding presumably similar to that of D. cepedianum. Capable of feeding opportunistically on fauna other than zooplankton (Ref. 5722, 10294).
