The Buzz: Fish Still in Trouble Despite Comebacks

For the first time in over a century, New York's Salmon River is home to its namesake species of fish. Young Atlantic salmon were abundant in the Salmon River and nearby Lake Ontario in the 19th century but were driven away by damming, pollution and overfishing—now, USGS scientists have reported that efforts to reestablish the salmon population are beginning to produce results. Atlantic salmon made a comeback this year in the Seine River as well after a similarly lengthy absence. But as Jennifer Jacquet warns on Guilty Planet, the prognosis for fish is still bad; the shrinking sizes of the catches on display at Tokyo's Tsukiji fish market are a glimpse of what is to come. The lush marine world that photoblogger B.N. Sullivan captures on Photo Synthesis may be increasingly harder to explore.
