Abstract: A method of controlling a target species using a first ROV and second ROV, by manoeuvring a probe attached to the first ROV to be positioned around the body of an individual of a target species, deploying a high tensile voltage between the terminals of the probe to stun and or kill the target species, and using a capturing arrangement attached to the second ROV to guide, direct or move the stunned or killed individual into a storage container attached to the second ROV. An ROV for collecting and transporting a target species may comprise at least one capturing arrangement to guide, direct or move a stunned or killed individual of the target species into the storage container.
