Generating consensus biomass estimates include providing a first biomass parameter data set associated with a first biomass attribute parameter to a first biomass estimation model and providing a second biomass parameter data set associated with a second biomass attribute parameter to a second biomass estimation model different from the first biomass estimation model. The first biomass estimation model is adaptively weighted with a first weighting factor relative to a second weighting factor for the second biomass estimation model. An aggregated biomass estimate is determined based on a combination of the first biomass estimation model using the first weight factor and the second biomass estimation model using the second weight factor.

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.

Aquarium feeding systems are disclosed. In one embodiment, a system (10) includes a flotation base (20) adapted to float on water and a clip (130) adapted to be removably inserted into and removed from the flotation base (20). The clip may hold food materials (e.g., seaweed) for feeding aquatic life of the aquarium.

A self-harvesting sustaining feed system includes a tank for housing fish, a frame located above the fish tank, one or more plant floats which float atop water within shelves held by the frame, and an insect tray for housing larvae. Temporary temperature changes in the insect tray cause the larvae within the insect tray to migrate out and fall into the fish tank below.

A smart aquaculture method is provided for an aquaculture system including a breeding pool, a feeding machine and a camera disposed in the breeding pool. The method includes: taking an underwater image by the camera; calculating a feed remaining amount according to the underwater image; and controlling the feeding machine according to the feed remaining amount to dispense feed to the breeding pool.
