An assembly designed to encourage fish to enter a Coanda effect fish pumping system head first to allow delicing through the pump. The assembly includes a funnel shaped tube made of spaced bars and a water distribution system that provides a current that fish will swim toward. Once within the funnel shaped tube, wall spacing allows the current to dissipate where a suction current of the pump further transfers the fish. The current changes within the Coanda effect pump provide delicing of the fish by orientating the fish in a forward direction as the fish pass through the pump.

Various implementations described herein are directed to a non-transitory computer readable medium having stored thereon computer-executable instructions which, when executed by a computer, may cause the computer to automatically receiving fishing data recorded during a fishing trip. The computer may receive a selection of a first group of subscribers that can access the fishing data. The computer may grant permissions to the first group of subscribers to access the fishing data.

[Problem]

To provide a fish sedating device capable of reliably energizing and sedating fish to satisfactorily perform a slaughter operation.

[Solution]

The fish sedating device includes fish placement means 3 on which fish F can be placed, electrodes 4a and 4b that energize the fish F placed on the fish placement means 3 through high-resistance water in a state present on the fish placement means 3 and having a higher electrical resistance than that of the fish, and a power source that supplies electricity to the electrodes 4a and 4b.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for underwater feed movement detection. In one aspect, the method may include the actions of obtaining images captured at different time points, where the images are captured by a camera and indicate feed that has been dispersed by a feeder for aquatic livestock inside an enclosure; determining, for each image, respective locations of the feed indicated by the image; determining, from the respective locations of the feed, a respective movement of the feed over the different time points; determining, based on the respective feed movement of the feed over the different time points, water current movement within the enclosure for the aquatic livestock; and outputting an indication of the water current movement.
