Method and system for external fish parasite monitoring in aquaculture

A method for external fish parasites, such as sea lice, monitoring in aquaculture, comprising the steps of: —submerging a camera () in a sea pen () comprising fish (); —capturing images of the fish () with the camera (); and —identifying external fish parasites such as sea lice on the fish () by analyzing the captured images, characterized by the steps of: —distinguishing between at least two different classes of external fish parasites such as sea lice which differ in the difficulty of recognizing the external fish parasites such as sea lice; —calculating quality metrics for each captured image, the quality metrics permitting to identify the classes of external fish parasites such as sea lice for which the quality of the image is sufficient for sea lice detection; and —establishing separate detection rates for each class of sea lice, each detection rate being based only on images the quality of which, as described by the quality metrics, was sufficient for detecting external fish parasites such as sea lice of that class.

System for external fish parasite monitoring in aquaculture

A system for external fish parasites monitoring in aquaculture, the system comprising: &#x2014;a camera () suitable to be submerged in a sea pen suitable for containing comprising fish, the camera being arranged for capturing images of the fish; and&#x2014;an electronic image processing system () configured for identifying external fish parasites on the fish by analyzing the captured images, wherein: &#x2014;a ranging detector () configured for detecting the presence of fish and measuring a distance from the detector to the fish is mounted adjacent to the camera (); and&#x2014;an electronic control system () is arranged to control a focus of the camera () on the basis of the measured distance and to trigger the camera () when a fish has been detected within a predetermined distance range.

Computing device with sensor

A robotic arm module includes a chassis having at least one arm pod. At least one arm connected to the chassis is movable between a stowed position within the at least one arm pod and a deployed position extending from the at least one arm pod. Each arm has a gripping mechanism for gripping articles of work. An attachment structure is configured to allow a host robot to grip and manipulate the robotic arm module. An electrical interface is configured to receive electronic signals in response to a user moving remote manipulators. The electronic signals cause the at least one arm to mimic the movement of the user moving the remote manipulators.
