摘要： In the present invention, an estimator for estimating the number of fish present in an underwater space is constructed by means of machine learning using, as teaching data, a plurality of data sets for learning that each include an echo image for learning, the echo image being based on received sound waves reflected by fish when sound waves are transmitted in an underwater space where fish are present, and the number of fish present in the underwater space in the echo image. The plurality of data sets for learning each include: an echo image for learning that is based on received sound waves reflected by fish when sound waves are transmitted in the underwater space where fish are present; and the number of fish present in the underwater space in the echo image. The estimator is used on an echo image generated on the basis of received sound waves reflected by an unknown number of fish present in the underwater space after transmitting sound waves in the underwater space, so as to calculate the number of said unknown number of fish present in the underwater space.

摘要： A Fishing Competition Management and Administration (FCMA) system includes communications and cull management capabilities. The FCMA system includes an angler-based system and an event organizer-based system. The angler-based system is based on a weigh scale and set of cull floats or markers for attachment to each caught and retained fish. The culling product includes the weigh scale and a set of six culling devices, each culling device has a different color. As a fish is caught and weighed, the Culling or Weight Scale will signal to a colored culling float in or outside of the live well. The culling scale determines and stores the weight associated with that particular-colored float and will properly record the weight next to the proper weight color on the screen.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for sea lice mitigation. In some implementations, a method includes generating (i) a first record for a first fish indicating an extent of sea lice infestation for the first fish at a first time and (ii) a second record, different than the first record, for a second fish, different than the first fish, indicating an extent of sea lice infestation for the second fish at the first time; and training, based at least in part on the first record and the second record, a model that determines, given one or more input records for a third fish, whether the third fish is likely to be healthy at a second time subsequent to the first time.

摘要： A computerized system of performing fish census which otherwise requires high level of domain knowledge and expertise is described. Divers with minimal knowledge of fish can obtain high quality population and species distribution measurements using a stereo camera rig and fish video analyzer software that was developed. The system has two major components: a camera rig and software for fish size, density and biomass estimation. The camera rig consists of a simple stand on which one to four pairs of stereo cameras are mounted to take videos of the benthic floor for a few minutes. The collected videos are uploaded to a server which performs stereo analysis and image recognition. The software produces video clips containing estimates of fish size, density and species biodiversity and a log report containing information about the individual fishes for further end user analysis.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for escape detection and mitigation for aquaculture. In some implementations, a method includes obtaining one or more images that depict one or more fish within an enclosure; generating, as a result of providing the one or more images to multiple detection models, a value that reflects a quantity of fish that are depicted in the images that are likely a member of each different type of fish; detecting an error condition relating to a possible opening of the enclosure based at least on the value; and in response to detecting the error condition relating to the possible opening of the enclosure, initiating one or more mitigation actions relating to the possible opening.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that validate the synchronization of controllers in an aquaculture environment. One of the methods includes an image processor that receives images generated by a first image generating device that includes a light filter that is associated with light of a particular light frequency while an aquaculture environment was illuminated with light. Based on the image that was generated by the first image generating device, the image processor determines whether the intensity value of the light frequency in the image satisfies a threshold value. Based on determining whether the intensity value of the light frequency in the image satisfies the threshold value, the image processor determines whether the aquaculture environment was illuminated with light of the particular light frequency when the image was generated. The image processor provides for output an indication of whether the aquaculture was illuminated with light of the particular frequency when the image was generated.

摘要： A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.

摘要： An information processing device includes a detection unit and a calculation unit. The detection unit detects, as a measurement use point, a portion that is used for prescribed length measurement of the object, in each of sectioned regions, in an object image included in the photographed image, set on both sides with respect to a reference line which is set for the object image and by which the object image is sectioned. The calculation unit calculates the length of a segment, in each of the sectioned regions, between the measurement use point and the intersection point between the reference line and a perpendicular line passing through the measurement use point and being perpendicular to the reference line. Further, the calculation unit calculates a length, in the object, to be measured, by adding together the calculated lengths of the segments.
