    摘要: This invention relates to a system for detecting and retrieving selected specimens being at least one of fish eggs, roe or fry, from a water containing hatching tray. The system including retrieving unit including a tube having a width comparable to the size of the specimens to be retrieved, the tube end being configured to be position in the water, and a pump device cable of pumping water and specimens from said tray. It also includes a robot unit moving the retrieving unit in a predetermined path related to a first reference system over said tray. The system also includes an imaging device being configured to detect and select specimens having chosen characteristics, and a control unit defining a second reference system defined by the position of a selected specimen relative to the position of the retrieving unit, the system being configured to move the tube end to the position of the selected specimen and pumping the specimen into the tube.

    摘要: A fish identification method is provided. The fish identification method includes capturing an image through a processor, wherein the image includes a fish image. The fish identification method includes identifying a plurality of feature points of the fish image through a coordinate detection model and obtaining a plurality of sets of feature-point coordinates. Each of the plurality of sets of feature-point coordinates corresponds to each of the plurality of feature points. The fish identification method further includes calculating a body length or an overall length of the fish image according to the plurality of sets of feature-point coordinates of the image.

    摘要: Embodiments of the present invention provide a novel deterrent barrier based on the phenomenon of fluid cavitation. A drive unit comprising a motor and a propeller are configured for inducing cavitation in water. The cavitation takes the form of a rotationally confined vertical column of cavitation bubbles extending from the propeller, and a one-dimensional series of drive units spanning the width of a waterway may provide an effective, environmentally friendly and non-lethal barrier against entry of target fish species.

    摘要: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for underwater camera biomass prediction aggregation. In some implementations, an exemplary method includes obtaining images of fish captured by an underwater camera; providing data of the images to a trained model; obtaining output of the trained model indicating the likelihoods that the biomass of fish are within multiple ranges; combining likelihoods of the output based on one or more ranges common to likelihoods of two or more fish to generate a biomass distribution; and determining an action based on the biomass distribution.

    摘要: Methods, systems, and apparatuses, including computer programs encoded on a computer-readable storage medium for estimating the shape, size, and mass of fish are described. A pair of stereo cameras may be utilized to obtain right and left images of fish in a defined area. The right and left images may be processed, enhanced, and combined. Object detection may be used to detect and track a fish in images. A pose estimator may be used to determine key points and features of the detected fish. Based on the key points, a three-dimensional (3-D) model of the fish is generated that provides an estimate of the size and shape of the fish. A regression model or neural network model can be applied to the 3-D model to determine a likely weight of the fish.
