Impact of river flow abstraction and global change on estuary associated fishes

Much is known about the biology and ecology of fishes in estuaries but detailed information on the factors influencing fish diversity and abundance is lacking. In an effort to provide some insight into the possible role of freshwater discharge on the diversity, abundance and energy flow pathways within estuarine fish assemblages, a series of studies have been conducted or are currently in progress. In addition, global change has resulted in other major impacts on fishes associated with estuaries and this issue is now receiving priority research attention.
