Selected freshwater or saltwater aquaculture systems are processed for the automatic removal of waste, ammonia, and pathogens while controlling temperature, oxygen, and feed amounts for obtaining maximum growth and survival at maximum aquatic species densities. A core platform treatment technology removes ammonia by combining chlorine with the ammonia to form chloramines, which are removed by catalytic activated carbon at a downstream filter station. Processing also removes potential pathogens by sterilizing and electrifying the water. The technology utilizes ammonia, chlorine, oxidation-reduction potential (ORP), and flow sensors to electronically adjust the amount of chlorine needed to remove the existing ammonia. A control system utilizes temperature, dissolved oxygen, and image processing sensors to optimize heating, cooling, feeding, and aeration.

Techniques and systems for robotic aquaculture are described. In one embodiment, for example, a mariculture system may include an aquatic animal containment system operative to hold a population of aquatic animals, the aquatic animal containment system comprising an enclosed hull having a receptacle configured to receive a mechanical core, the mechanical core configured to store at least one sub-system to implement at least one function of mariculture system, and a position management system operative to maintain the enclosed hull at a depth below a surface of a body of water. Other embodiments are described.

The invention relates to water regeneration in a fish breeding complex combining closed and flow-through water supply systems. A module of a biological filter in a water regeneration system comprises a reservoir, an aerator, a channel for sludge accumulation and discharge and a reservoir bottom sloped in direction of the water movement and, with the water surface, forming a diffuser providing for circulation of water and filler in the biological filter. Fish breeding complex comprises fish breeding pools and a water regeneration system comprising a mud settler-denitrificator, a device for water lifting and aeration, a biological filter, degassing and disinfection units. Each fish breeding pool comprises water oxygenation and disinfection systems, dosage units, water discharge systems and insoluble residues collecting and discharge systems. In the water flow-through mode, water regeneration system is switched off and water supply from an outside source and wastewater discharge are switched on.

A device for fish reproduction, hatching and larval culture including an aeration device, a first netted division plate, a second netted division plate, a first water pump, a first net cage, a second water pump, and a second net cage. When in use, the device is disposed in a pond. The pond includes a breeding area, a hatching area, and a nursery area, and each of the breeding area, the hatching area, and the nursery area communicates with the other two. The first netted division plate is disposed between the breeding area and the hatching area, and a first water recirculating loop is formed between the breeding area and the hatching area to drive water to flow from the breeding area to the hatching area, and back to the breeding area. The second netted division plate is disposed between the hatching area and the nursery area.

Provided is an ultrafine bubble generation device for aquaculture or wastewater treatment with which it is possible to efficiently cause ultrafine bubbles to be dissolved or to coexist, and to increase the concentration of a gas in the liquid. An ultrafine bubble generation device for aquaculture or wastewater treatment provided with a channel for channeling a liquid, a compression device for pumping a gas into the channel, and a bubble generation medium for releasing the gas pumped by the compression device as ultrafine bubbles into the liquid in the channel, wherein the bubble generation medium is formed from a carbon-based porous material and is disposed so as to be horizontal or below horizontal with respect to the direction of flow of the liquid in the channel.

Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

An interactive fish tank system includes a nozzle array provided in a water tank, wherein a plurality of bubble nozzles from which bubbles are emitted are arranged in the nozzle array; a computing device configured to receive user action information inputted from at least one user action input device, generate bubble conversion information by which characteristics of the user action information are expressed as bubbles generated from at least one of the plurality of bubble nozzles, and generate a control signal for supplying air to emit bubbles corresponding to the bubble conversion information; and an air injection device connected to the plurality of bubble nozzles through hoses, wherein the air injection device supplies air to at least one of the plurality of bubble nozzles based on the control signal.

The use of small solar cells for automatic aeration of systems is currently unavailable due to the tow efficiency of solar cells. With my invention, this would become possible. With this innovative design and setup, a very cost-effective automatic solar air pump can be used in different applications and systems. The solar air pump can work even on cloudy days and would have stored energy to work at night.

Solar Cells and Panels have power absorption limitations and are less efficient if the Solar Panel is not tilted in right way to the Sun to absorb the maximum amount of Solar Energy. They are also limited and inefficient during cloudy and rainy days. Dust and shading also reduces the energy and power absorption of Solar Panels.

In a small-scale application, for example with a Solar Panel with an area of 5.5 inches×4.5 inches, it is normally very difficult for the Solar Panel to power gadgets and appliances.

I decided to first focus on the Air Pump system for aquariums, aquaponic systems, hydroponic systems, bore holes and Irrigation.

A delivery device and system to supplement CO.sub.2 in an underwater environment without the need for electricity or the use of compressed CO.sub.2. The device consists of a container containing a biological organism such as mycelium and including an exit portal for CO.sub.2 to enter the underwater environment. The device may also incorporate a separation device to delay and control the flow of CO.sub.2. The system requires the device to be held in place through a securing point in the underwater environment. The minimum requirements for the device are described, but in certain instances it will be preferably used with a double-bag or an outer shell housing to protect or aesthetically conceal the placement underwater. The use of this device and system to supplement carbon dioxide in water will span many industries and applications. It will assist with mosquito trapping. It will also supplement CO.sub.2 in underwater growing environments.
