Fish species observed in a Maine estuary

What is it about?

In order to conserve and manage ecosystems and fisheries, scientists need to know what species inhabit a system and when. The fishes of the Saco River estuary, however, had not been studied in 30 years. In response, fish were collected using a variety of gear throughout 2007 and 2008. Twenty-four species of fish were observed, and it was found that most fish were using the area as juveniles. In addition, several species that were found are of federal conservation concern.

Why is it important?

Our work identified that the fish species composition of the Saco River estuary has changed considerably in the past ~30 years, with multiple species that were previously abundant being no longer present. In addition, several species of federal concern were observed within the system. These federal species of concern included Atlantic sturgeon, blueback herring, and rainbow smelt. Other species of note were winter flounder, American eel, Atlantic herring, and bluefish, which support fisheries.
