A system for causing an upwelling to create a fishery without altering thermoclines in a body of water, having: an electric pump housed in a floating buoy; and a heat exchanger hose having a plurality of protrusions; wherein the heat exchanger hose and the electric pump are configured to pump nutrient-rich water from a first depth of the body of water to a second depth of the body of water closer to a surface of the body of water than the first depth; wherein the plurality of protrusions is configured for transferring heat from surrounding waters to the pumped water; and wherein the system releases the pumped water only when it is warmed to around the ambient water temperature of the second depth of the body of water, such that the pumped water remains at the second depth without immediately sinking back down to the first depth.

A method for adjusting an aquarium water temperature through direct heat exchange by a water temperature adjustment apparatus for an aquarium includes: a first step of allowing a smart sensor unit to measure the temperature of the water; a second step of controlling a heat exchange adjuster that sunk in the water to adjust the temperature of the water based on the temperature of the water measured by the smart sensor unit; and a third step of allowing the heat exchange adjuster to adjust direct heat exchange with the water.

A system for heat and light management for indoor horticulture is described. More particularly, a system including light sources, a light distribution chamber, and circulating water is described.

A lighting system includes an ultraviolet (UV) light source including a UVA light source configured to emit UVA light having various wavelengths; and a UVB light source configured to emit UVB light and control a lighting direction of the UVB light towards a target, a sensor including a UVA sensor configured to sense the UVA light, and a control unit configured to control lighting characteristics of the UV light source, in which the lighting characteristics include an intensity of the UVA light.

Disclosed are livewell systems and methods of operating livewell systems. A livewell system may include a livewell tank having a chamber formed therein, a fill sensor configured to detect a fill level of the chamber, an intake pump configured to selectively convey water into the chamber, and a control unit including a processor and a memory storing instructions. The processor may be configured to execute the instructions to receive a fill signal, determine whether the chamber is filled to a predetermined fill level; and in response to the fill signal and a determination that the chamber is not filled to the predetermined fill level, cause the intake pump to convey water into the chamber.

A system and method for the long-term preservation of crustaceans, particularly crawfish. Certain embodiments sort quantities of live crawfish into tightly-packaged bags for rapid freezing to minimize damage to the crawfish and enhance the effectiveness of the preservation process.

A shipping container that includes a greenhouse mounted above an aqueous tank or tanks. Aquaponics fruits and vegetables grow in greenhouse in vertical and horizontal grow systems, while fish are grown in the tanks. Water flows between all plants and fish with no soil. The system is run by a computer automation system which operates on data obtained by various sensors and control components that include automated control valves, fish feeders, temperature and water flow measurements. The container can be operated from an established grid or can run off-grid with solar or other renewable energy sources. Part of the water needed for the system can be collected from rainfall. All necessary components except for the water, fish and plant seedlings are delivered in the shipping container.

The present invention provides a waterless keep-alive apparatus and a refrigeration appliance having the same. The waterless keep-alive apparatus is provided in an inner tank of a refrigeration appliance, and comprises: a keep-alive box allowing pulling inward and outward; a temperature controlling module and a humidity controlling module which are connected with the keep-alive box; and an air controlling module having an air hole provided on a side wall of the keep-alive box and an air duct fixed on the inner tank of the refrigeration appliance. The air duct is hermetically connected with the air hole when the keep-alive box is pushed into the inner tank of the refrigeration appliance. The air duct is disconnected from the air hole when the keep-alive box is pulled out. The waterless keep-alive apparatus realizes convenient article fetching while the oxygen concentration in the keep-alive box can meet the survival needs of aquatic products.

A system for maintaining the health of captive fish in a mobile environment, comprising a live well for containing fish in a fluid medium, a plurality of thermoelectric coolers affixed to the live well, and a live well controller for controlling a direct current applied to the thermoelectric coolers, and a method for maintaining a consistent temperature comprising the steps of setting an initial temperature, applying a current to thermoelectric coolers, reading a new temperature, and adjusting the current based at least in part on the new temperature reading.

This invention is related to an aquaculture heating device. A heating unit is hung on a support rod, so that the support rod can be horizontally placed above an aquaculture and two ends of the support rod can be fixedly positioned on two sides of the aquaculture to let the heating unit hung on the support rod to be dropped and immersed in the water of the aquaculture when winter, especially cold stream, comes. When electricity is provided to conductive yarns of a heating layer of the heating unit, heating filaments of the conductive yarns will generate heat to be transferred to the water and gradually diffused throughout the aqua culture through the waterproof fabric layer. Thus, the water temperature is raised to effectively help the aquatic organisms to resist the cold winter and not to be frozen to death caused by the very low water temperature.
