The present disclosure provides systems for heat source, e.g., data center, cooling and aquaculture. In certain aspects, the systems include a heat source, e.g., data center, having a water cooling subsystem configured to receive cool water and output warm water and an aquaculture center co-located with the heat source, e.g., data center, and configured to receive the warm water. Aspects of the invention also include methods for cooling a heat source, e.g., data center, using a water cooling subsystem and cultivating aquatic organisms with an aquaculture center that is co-located with the heat source, e.g., data center.

The invention concerns an apparatus for cleaning a surface immersed in a liquid, notably a swimming pool cleaning robot, including a body, said body including lower, upper and lateral walls configured so that said lower wall is intended to be positioned facing the immersed surface over which the apparatus (10) moves, said upper wall is opposite said lower wall, said lateral walls connect said lower and upper walls, means for moving the body (11) over said immersed surface. Said apparatus also includes a central chamber (15), situated inside the body (11), and including a filter basket (151), said filter basket (151) including a filter wall, and an opening (113) enabling extraction of said filter basket (151) from the body (11). Furthermore, said opening (113) is on a lateral wall of the body (11).

The invention relates to a system for the elimination of parasites adhered to fish, by directly applying electricity to the fish, thereby removing the parasites without harming the fish, the system comprising: an entry and drainage area (1) that allows the fish to be separated from the water transporting them, which is joined to an application area (2) where electricity is applied to the fish, by means of contact with electrodes (3, 3b) such as curtain electrodes (3) and/or grill electrodes (3b), the electricity being controlled by a control unit (4) that regulate and sets the intensity, voltage and electrical frequency required to remove the parasites without harming the fish; spray nozzles (5) installed in the application area, which spray water on the fish to cause the parasites to fall off and move through a return chute (9) that is installed below the application area to receive the sprayed water and parasites contained therein and channel same into a drain; a capturing filter (6) installed in a drainage pipe of the return chute, which traps the parasites, allowing only water to pass to a pond (7) that stores the water for spraying and recovers the water by means of the return chute (9); a pump (8) that pumps the water to the spray nozzles (5); and an outlet (10), tube or pipe joined to the application area, through which the fish return to their environment, without parasites.

A method, a device and a fish-farm for controlling the concentration of living organisms in fluid in order to facilitate the handling of the organisms such as grading and counting. The apparatus comprises a first in-feed channel for a flow of living organisms, a second in-feed channel for a flow of fluid, a chamber containing a lever for regulating the flows from the first and the second in-feed channels through the chamber, an outlet, a computer, and a sensor. The sensor is positioned in the first in-feed channel for detecting the density of living organism in the flow, and the computer continuously and automatically regulates the ratio of flows from the first and the second in-feed channels through the chamber and towards the outlet by the lever in response to the density of living organisms in the flows determined by the sensor.

Provided is a method of monitoring a heart rate of an open circulatory system aquatic organism including water fleas, zebrafish, brine shrimp, and the method of evaluating individual response by real time measurement of a heart rate of an aquatic organism and the individual response evaluation apparatus by real time measurement of a heart rate of an aquatic organism according to the present invention may effectively fix the aquatic organism for real time measurement of the heart rate of an aquatic organism, and may measure the heart rate using digital holography to display the heart rate while configuring a data format to allow the corresponding data to be stored for a long time, thereby treating a compound for inducing an individual response, securing a heart rate change in real time by image processing, and then effectively determining the presence or absence of harmfulness due to induction of the individual response.
