Fish of the Río Rincón, Costa Rica

835 627 Stroud Water Research Center

In November 2013 researchers from Stroud™ Water Research Center visited the Río Rincón on the Osa Peninsula in Costa Rica to scope out potential sites for an upcoming survey of the physical, chemical, and biological status of streams and rivers of the Osa Peninsula. This movie shows three fish species that were observed in a pool next to the river: the molly Poecilia gillii, and the cichlids Cryptoheros sajica, and Amphilophus lyonsi (tentative identification).
