Video Hatch: Porpoising Bonefish

May 20, 2011 By: Marshall Cutchin

University of Massachusetts Amherst researcher Andy Danylchuk and colleagues from several other institutions used ultrasonic transmitters to tag and track bonefish movements off Eleuthera in the Bahamas. Their results appear in an early online issue of the journal Marine Biology.

A new video shows “unique pre-spawning behaviors such as porpoising, which is when bonefish breach the water’s surface as they leave nearshore pre-spawning aggregation sites at dusk on their way to deep offshore spawning sites.”
