A fish monitoring system deployed in a particular area to obtain fish images is described. Neural networks and machine-learning techniques may be implemented to periodically train fish monitoring systems and generate monitoring modes to capture high quality images of fish based on the conditions in the determined area. The camera systems may be configured according to the settings, e.g., positions, viewing angles, specified by the monitoring modes when conditions matching the monitoring modes are detected. Each monitoring mode may be associated with one or more fish activities, such as sleeping, eating, swimming alone, and one or more parameters, such as time, location, and fish type.

A test device for noninvasive testing of fish habitat selection and application thereof is described herein. The device includes a camera device, a water circulating system, a fish transporting barrel, and a test water tank. The fish transporting barrel is a water barrel with an openable bottom. The central area of the test water tank is arranged as a closed adaptation area, a water outlet is formed in the bottom of the adaptation area. Fish passages are formed in the adaptation area. Test areas with equal sizes are formed around the adaptation area through partition plates. A water inlet is formed in each test area. Water flow buffering plates are arranged corresponding to the water inlets. Fish passages are formed in the bottoms of the partition plates of the test areas. The water inlets of the test areas are connected to the water circulating system.

A system for managing and monitoring a sensor network that senses pest activity. A plurality of sensor stations may be controlled by the system, such sensor station configured for detecting the presence of pests at a baiting station, or for alerting users to the presence of a pest in a trap, as well as a related system of data collection and data management of pest activity data.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for sorting fish in aquaculture. In some implementations, one or more images are obtained of a particular fish within a population of fish. Based on the one or more images of the fish, a data element is determined. The data element can include a first value that reflects a physical characteristic of the particular fish, and a second value that reflects a condition factor of the particular fish. Based on the data element, the fish is classified as a member of a particular subpopulation of the population of fish. An actuator of an automated fish sorter is controlled based on classifying the particular fish as a member of the particular subpopulation of the population of fish.

A method of moving farmed aquatic animals from a tank containing the animals, the tank having a tank outlet and a conveyance pipe, the conveyance pipe having a conveyance pipe inlet connected to the tank outlet and a conveyance pipe outlet at an outlet elevation higher than the tank outlet, the method comprising: (i) by means of a water inflow into the tank, maintaining a water level in the tank at a level above the outlet elevation to generate a flow of water from the tank through the conveyance pipe while positioning a moveable water-permeable screen inside the tank to crowd the animals towards the tank outlet, (ii) by means of the flow of water therethrough, moving animals through the conveyance pipe.
