EcoSCOPE

By imitating the long, thin snout of the garfish protruding into the security sphere of the alert herrings, an endoscope with a tip diameter of 11 mm is used.Additionally, the front of the ROV is covered by a mirror, reflecting a light gradient resembling the natural scene and making the instrument body virtually invisible to the animals.Another advantage of these small "optical probes" is the minimal disruption of the current-field in the measuring volume, allowing for less disturbed surveys of microturbulence and shear.EcoSCOPE systems have already been tracking water pollution and its effect on fish and plankton behavior in Europe and the United States).For the future it is anticipated to deploy ecoSCOPEs continuously online, within the project LEO Projekt off New York City, visible for the public.
Video (50%, looping, each image shifted to compensate the rolling microturbulences from the waves) of feeding juvenile herring (38 mm) on copepods - the fish approach from below and catch each copepod individually. In the middle of the image a copepod escapes successfully to the left.
