The present invention relates to fluid pump assemblies in general, and in exemplary embodiments to fluid pump assemblies that are magnetically supported in position, and to related kits and methods useful to circulate water in aquariums. The fluid pump assembly comprises an outer mount, an inner mount, and a pump. The outer mount includes at least one outer permanent magnet; the inner mount includes at least one inner permanent magnet; and the pump includes at least one soft magnetic material. The outer permanent magnet, the inner permanent magnet, and the soft magnetic material collectively form a magnetic circuit.

A closed recirculating aquaponics system combined with a biofloc tank for symbiotic breeding of aquatic species and plant species, wherein the culture water for growing aquatic species is transferred to a plant growing apparatus, organic material in the culture water is used as nutrients for plant species and the water is purified in the plant growing apparatus, and purified water is reused as culture water for aquatic species to facilitate symbiotic breeding of aquatic species and plant species without any need of culture water exchange, reducing cost for production and enhancing production efficiency.

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.

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.
