The breeding tank is provided with water lanes for separating infant (fry), young, and grown fishes from each other, each given a circular water current. In the purified water tank, there is placed water filtering means and purified (filtered) water is stored there.

Abstract: A system and method provide an intensive aquaculture system for producing caviar or other goods. The system has a photosynthetic subsystem to consume waste from a production species, a food production subsystem to consume the photosynthetic species and be eaten by the production species. Optionally, the food production species may be pelletized or otherwise refined before being consumed by the production species. While each subsystem may have its own water chemistry, gas scrubbers may be used to control gas levels among the subsystems. In one implementation, an enclosure is used with a sensor to measure the gas above the water in the photosynthetic species. Water and species may be transferred among the subsystems as desired. Multiple aquaculture systems may be used in combination to provide age-specific systems operating in conjunction with one another and distribute risk of disease or failure across multiple systems.

Abstract: An aquarium water changing and stabilization system consists of an initial tank designed to stabilize and condition water before it is entered into a subsequent tank that contains live aquatic animals such as fish. This system has a cabinet that is designed to aesthetically enclose, protect and support the components of the aquarium while providing access to the system. Water is introduced into the system from existing hot and cold water plumbing which is connected to this system. Water exits from this system into existing sewerage plumbing which is also connected to this system. Conditioned water from the conditioning tank enters the main fish tank via plumbing from one tank to the other. In case too much water is introduced to either tank, overflow drains in both tanks prevent water from overflowing over the top of either tank. Plumbing check valves and ball valves create safe and easy plumbing.

Abstract: A liquid handling system transfers liquid (e.g. water, bearing marine animals) between two tanks each having a respective liner which is movable between a lining position (when filled with liquid) and an inverted position (when its respective tank is emptied). In an initial state, liquid is held in a first tank. By supplying air to a space between the first tank and its liner, its liner is progressively lifted and liquid passes along a channel onto the initially inverted second liner (which acts as a baffle to slow the liquid flow). Air in a space between the second liner and the second tank is vented so transferred liquid sinks the second liner to fill the second tank. A ballast liquid may be used in the spaces. Initially held in the second tank, the ballast liquid flows via a passage into the first tank as transfer of liquid progresses.

Abstract: A portable automated biomonitoring system for monitoring water quality includes an exposure chamber for housing an aquatic organism and a water inlet for directing water to the exposure chamber. The aquatic organism has ventilatory behavior and body movement sensitive to water quality. Electrodes sense electrical signals produced by the organism during its ventilatory behavior and body movement, and a controller responsive to signals from the electrodes determines a plurality of ventilatory parameters based on the signals. The ventilatory parameters are compared with corresponding thresholds to determine when the water to which the organism is exposed has caused physiological stress to the organism. The water being evaluated may be recirculated through the system for further analysis.

A cover covers the opening and is spaced therefrom to provide an inlet opening positioned above the bottom of the tank. A transition zone is formed at the bottom of the tank surrounding the standpipe and a debris outlet is provided from this zone through the bottom of the tank for removal of debris separated in the transition zone. Cleaned water from the transition zone flows up around the standpipe, through the inlet opening and into the standpipe for removal from the tank.

Abstract: An automated biomonitoring system for monitoring water quality includes an exposure chamber for housing an aquatic organism having ventilatory behavior and body movement sensitive to water quality. Electrodes capture electrical signals produced by the organism during its ventilatory behavior and body movement, and a controller responsive to signals from the electrodes determines one or more ventilatory parameters based on the signals. The ventilatory parameters are compared with corresponding thresholds to determine when the water to which the organism is exposed has caused physiological stress to the organism. The signals captured by the electrodes may be corrected for variations in water conductivity so that the signals processed by the controlled are not influenced by conductivity.

Abstract: Tank cleaning system is formed by an upper deck having a spout potion and a deck portion, injectors and a separation chamber having a conical bottom wall and a top formed by a waste baffle. The injectors connect the deck portion with the separation chamber so that the waste baffle and upper deck are axially separated to provide an outlet passage therebetween. The injector passages direct water through the upper deck and waste baffle into the lower chamber and impart a significant velocity component tangential to the chamber to the water flowing therethrough to impart a helical flow to the water in the chamber. A debris outlet passage is provided adjacent to the bottom of the lower portion of the chamber. The dirt laden stream enters the chamber through the injectors and dirt is separated by centrifugal action in the chamber and rejected through the debris outlet while the cleaned water passes through the outlet passage and is returned to the surrounding water.

Abstract: The present invention provides a compact culture system to produce microalgae, live food animals and fish fry (new born fish) in a serial manner. The culture system is composed of three individual reactors of same size positioned in different levels on three shelves of a frame. In the top-level reactor, microalgae is grown symbiotically with fish. With so grown microalgae, live food animals in the middle-level reactor are fed. Finely, the live food animals are transferred into the bottom-level reactor to feed fry in it. Culture water in the system is self-cleaned by the metabolic activity of the photosynthetic microalgae, and is circulated through the reactors continuously or intermittently. Heaters, thermometers, aerators, illuminators, and water pumps are equipped in the system to offer optimal growth conditions for the organisms. Extra electric outlets are provided for the use of pH-meters, oxygen-meters, carbon dioxide-meters, ammonia-meters when needed to control the water quality.

Abstract: Aquatic animals that emit electrical signals are used to detect changes in the operating conditions of an aqueous medium (e.g., the presence of a pollutant). In one embodiment, the aquatic test animals are fishes of a species known as Apteronotus albifrons, whose electrical signals have frequency variations on the order of 0.1% under constant operating conditions; the temperature of the aqueous medium is stabilized to within 0.1.degree. C.; each aquatic test animal is placed in a perforated refuge within a holding tank in which the aqueous medium flows in a vertical direction; and three or more aquatic test animals are used, wherein phases of nychthemeral activity of the aquatic test animals are artificially offset to achieve overlapping of the nychthemeral activity of the aquatic test animals. All of these combine to yield a highly sensitive and reliable system for real-time biological monitoring of physico-chemical parameters of an aqueous medium.
