Abstract: The Delaware Bay is the third largest estuary in the US and home to over 200 species of finfish and shellfish, many ecologically and economically important. Delaware Fish and Wildlife has conducted a unique trawl survey in the Delaware Bay, dating back to 1966, which takes place once a month at fixed sampling stations. Using the data from this survey, we characterized the Delaware Bay fish and macroinvertebrate community, identified environmental drivers, and explored long-term patterns. In the past six decades, species richness in the Delaware Bay has steadily increased, largely due to community-wide reorganization. This community shift is likely driven by changing physical conditions and has implications for monitoring and management of East Coast fish species.
