This video of fish literally jumping into the boat has made the rounds on the Internet. The great debunker of Urban legends has found the source:
The video is a shortened version of a longer clip that originated on the Brazilian Pesca Rondônia web site. (“Pesca” is the Portuguese word for “fishing,” and Rondônia is a northern Brazilian state in the Amazonian region known for its great fishing rivers.) The footage was taken in the Guaporé region, on a portion of the Mequens River inside the Porto Rolins Park (a protected conservation area) where fishing is forbidden. The jumping fish shown in the video are matrinxã (Brycon cephalus), a Brazilian fresh water species.
