Monitoring systems and methods for tracking movement of one or more animals in an enclosure, such as a fish tank, include introducing various stimuli, such as food, light, and auditory stimuli, and tracking the movement of the animals in response to these stimuli. Movement patterns of the animals can be determined and analyzed from data obtain from cameras that record images/videos of the relevant portions of the enclosure.

Disclosed is a feedback feeding system pond recirculation with fusion of machine vision and infrared detection. Feeding strategies are provided according to the feeding behavior of fish in cooperative with machine vision technology and infrared sensing technology. The pond recirculating aquaculture is an open environment. The change of natural environment may affect the feedback signal of the fish feeding behavior provided by the machine vision due to the low visibility; or it may affect the feedback signal of the fish feeding behavior provided by the infrared detection because low temperature may decrease feeding intensity. The fusion of these two strategies can solve the problem of intelligent feeding strategies in the pond recirculating aquaculture mode.

An artificial propagation method of Sinocyclocheilus rhinocerous, comprising placing female and male parent fish in a sterilized culture container in which a black cave simulant is placed in advance, strictly controlling the environmental parameters of the parent fish culture. The method realizes natural spawning and sperm production of S. rhinocerous under artificial conditions without using oxytocin. There is no oxytocin used in the artificial propagation, thus not only obtaining a higher fertilization rate and incubating rate, but also reducing the aquaculture cost. The operation is simpler and faster. At the same time, different feeds are fed in different growth stages according to the different growth characteristics of each stage of S. rhinocerous fry, thereby increasing the survival rate and reducing the deformity rate of fries. Therefore, the method provided by the present disclosure realizes efficient artificial propagation method of S. rhinocerous.

A method of monitoring water tank includes receiving a temperature data set, a water conductivity data set, and a water level data set, characterizing measurements of a plurality of characteristic properties of water within a water tank by a sensor operatively arranged within the water tank. The method further includes determining a first rule characterizing environmental requirements of the water arranged within the water tank. The method further includes generating an output data set based on the received data sets and the first rule. The method further includes providing the generated output data set. Related apparatus, systems, techniques, and articles are also described.

Apparatus and associated methods relate to selectively inducing ingress and/or egress of live food creatures (FCs) relative to a reservoir using a controllable light source based on innate behavior(s) of the FCs. In an illustrative example, a feeder for dispensing live food to a carnivore may have a (partially) opaque chamber configured to receive FCs. A controlled light source may, for example, be selectively operable to illuminate at least part of the chamber. A carnivore interface may, for example, be in communication with the chamber via at least one dispensing aperture and be configured to present a dispensed FC to the carnivore. Operation of the controlled light source in a dispensing mode may induces motion of the FCs in the chamber towards the carnivore interface to be presented as food to the carnivore. Various embodiments may advantageously induce self-dispensing and/or self-retention of insects as food.

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 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.
