Working Waterfront: Will the fish come back? Will the fish make it to their spawning grounds?
These are the questions on the minds of fisheries biologists and river advocates this time of year, as they pay close attention to dam removals and other restoration efforts on streams and rivers.
Many of these restoration projects began decades ago and focused sharply on the endangered Atlantic salmon, but scientific perspective has widened to the entire complex of sea-run or diadromous fish that move between salt and fresh water, in order to restore the complete ecology of coastal watersheds.
Recently, another group of people have been watching, too: commercial fishermen, oceanographers and marine biologists who suspect that restoring populations of smaller sea-run fish like alewives and rainbow smelt will benefit ocean fish like cod.
