A device and method are provided for enhancing the feeding response of larval fish to feedstock. A food distribution mechanism is positionable above the tank housing the larval fish and is adapted for receiving the feedstock therein. The food distribution mechanism selectively deposits portions of the feedstock into the tank. A light source is positionable adjacent the tank and selectively directs a laser beam at the tank. A controller is operatively connected to the food distribution mechanism and the light source. The controller is configured to actuate the food distribution mechanism for a time period at selected intervals such that the food distribution mechanism deposits a portion of the feedstock into the tank during each time period. In addition, the controller is configured to actuate the light source for at least a portion of each time period.

The at least one pump configured to pump the liquid from the at least one tank through the at least one propagation module. Modular methods for propagating plants in at least one of a hydroponic environment and an aquaponics environment are also disclosed.

An aquarium requiring no more than only a single power connection. The aquarium includes: (a) a transparent tank having a surrounding wall with an enclosure rim surrounding an open top and an opposite closed bottom wall; (b) an electrically powered lighting arrangement; (c) an electrically powered pump oriented within an interior of the tank; (d) a base supporting the tank under the bottom wall of the tank; and (e) a junction box integrally formed with the base and having an aperture arrangement accessible from adjacent the surrounding wall having an electrical power port for removable insertion of an electrical power cord to provide power for the lighting arrangement and the pump.

Disclosed is an automated aquaponics apparatus. The aquaponics apparatus may include at least one fish holding tank configured to contain water. Further, the aquaponics apparatus may include at least one hydroponic unit. Further, the aquaponics apparatus may include a bio-digester. Further, the aquaponics apparatus may include an atmospheric water generator and a desalination reverse osmosis system. Further, the aquaponics apparatus may include an energy production system configured to generate energy. Further, the aquaponics apparatus may include at least one sensor configured to sense at least one variable. Further, the aquaponics apparatus may include a control unit configured to control an operational state of one or more of the at least one fish holding tank, the at least one hydroponic unit, the bio-digester, the desalination reverse osmosis system and the energy production system.

The present disclosure relates to a method of culturing a floating aquatic species, the method including introducing the aquatic species into a receptacle having (a) a culture medium, (b) at least one raceway configured to allow the culture medium to flow in a continuous loop, and (c) a sufficient quantity of the culture medium to flow in the continuous loop; cultivating the aquatic species to generate a floating mat on a top surface of the culture medium; generating a fluid current of sufficient force to propel the floating mat on the top surface of the culture medium; and varying a velocity of the fluid current in a controlled manner to maintain a relatively uniform distribution of the floating mat on the top surface of the culture medium.

A system for dispersing a chemical in a surface water body includes an aerator device, having an injector positioned at a bottom of the surface water body; and a holding tank to store the chemical adjacent to the surface water body; and a metering pump connected to the holding tank, the metering pump having a computing device to program the metering pump; the metering pump is programed to inject an amount of the chemical to the injector at a rate; and the injector disperses the chemical throughout the surface water body.

An automatic aquarium system that uses an automatic aquarium siphon bridge comprises a first water tank and a second water tank. The system further comprises a siphon bridge arranged between the first water tank and the second water tank. The system also comprises a pump arranged in one leg of the bridge. The aquarium system also comprises a cross over siphon arranged within the siphon bridge wherein one end of the cross over siphon is connected to an inlet of the pump and the opposite end is arranged in the second water tank. The automatic aquarium system may also comprise an air extraction siphon arranged between a top surface of the bridge and the inlet of the pump. This may allow for clean well aerated water to circulate throughout the automatic aquarium system, i.e., between the first and second tank via the bridge to allow for fish to properly enjoy two tanks and the bridge area therebetween.

A sterilizer for an aquarium includes a pump for sucking water in an aquarium and a filtering member for filtering the water. The pump includes an inlet from which the water in the aquarium is sucked. The filtering member is connected to the underside of the pump and includes an outlet through which the filtered water flows back into the aquarium. Multiple reflectors are connected to the periphery of the filtering member, and a coat is mounted to outside of the filtering member and covers the reflectors. Multiple ultraviolet sterilizer bulbs are located in the filtering member so as to treat the water sucked from the pump. A cotton sleeve is mounted to the pump and located around the inlet to remove debris and grease.

Disclosed is an aquarium that includes a tank, a magnetic induction transmission apparatus, and a first electric equipment disposed in the tank. The magnetic induction transmission apparatus includes a driving module and a receiving module. The driving module is disposed outside the tank and adjacent to a tank wall of the tank and is configured to be separable from the tank, and the receiving module is disposed on the tank wall of the tank and disposed corresponding to a position of the driving module. The driving module is connected to an external power source. The receiving module is connected to the first electric equipment and is operative to generate an induced current when the driving module is powered on.
