Sensory cues and mechanisms involved in the capture of euphausiids by the Australian salmon, Arripis trutta (Bloch & Schneider)
Experiments indicated that the initial detection of euphausiid prey by Arripis trutta is visual with the cues being shape and/or movement. Immediately before capture of prey in midwater, swimming speed of the fish increased from 15 to 33 cm s −1 . The sequence of morphological events during capture...

Summary: | Experiments indicated that the initial detection of euphausiid prey by Arripis trutta is visual with the cues being shape and/or movement. Immediately before capture of prey in midwater, swimming speed of the fish increased from 15 to 33 cm s −1 . The sequence of morphological events during capture is similar to that described for suction feeding in other teleosts such as Atlantic salmon Salmo salar . Occasionally prey would be ejected from the mouth after capture by means of a reversal of the mechanism used in suction feeding. |
