Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
The behaviour of the scorpionfish Helicolenus dactylopterus and Pontinus kuhlii towards the zooplanktivores Anthias anthias and Callanthias ruber are described from rare in situ remote-operated vehicle (ROV) observations. The events were recorded by ROV SP on gorgonian habitats of Dentomuricea meteor and Viminella flagellum at the summit of Condor seamount (212–223 m; Azores, Northeast Atlantic). Behaviour in both species included approaching the zooplanktivores from a sitting position, orientating the snout in front of the object and swimming in a straight line. After an initial slow displacement, it follows an adduction of dorsal, pectoral and anal fins and an increase in speed, occasionally accompanied of a burst swim. H. dactylopterus can reach up to 0.8 m above the seafloor, departing from more than 1.5m distance; P. kuhlii was observed only on one occasion, chasing A. anthias from 0.64-m distance, with average swimming velocities of 1–2 m/s. The possibility of predatory or agonistic behaviour is discussed, with more evidence being gathered towards the former, representing a possible linkage between the pelagic and the benthic realm. |
