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.

Adaptive feeding of aquatic organisms in an aquaculture environment. Sensor data is received from an aquaculture environment sensor. The sensor data reflects environmental conditions in the aquaculture environment. Feed selection data is determined based on the sensor data. The feed selection data is sent to a feed controller thereby causing the feed controller to dispense one or more feed materials into the aquaculture environment. Alternatively, the feed selection data is sent to an electronic feed ordering system thereby causing an aquaculture feed provider to ship a feed material.

Aquarium feeding systems are disclosed. In one aspect, a system (10) includes a flotation base (20) adapted to float on water, and a feeding apparatus adapted to be repeatedly inserted into and removed from the flotation base (20). In one approach, the feeding apparatus comprises a flotation insert (30) and a food tray (40). The food tray (40) comprises a plurality of apertures (46) sized to allow passage of aquatic food into an aquarium. In another approach, the feeding apparatus comprises a clip (130) suited to hold seaweed or other food materials. In another approach, the feeding apparatus comprises a basket (230) for holding food materials, the basket (230) having one or more apertures (246) sized to allow passage of aquatic food into an aquarium.

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.
