Arc modular light devices, systems, and methods. In at least one exemplary embodiment of a module system of the present disclosure, the module system comprises a plurality of LED modules, each LED module comprising an outer housing, a light source positioned within the outer housing, and a lens positioned so that light from the light source can be emitted through the lens; and a plate configured to couple to each of the plurality of LED modules; wherein the module system is configured to focus light from the LED modules inward when the plate has a concave curvature; and wherein the module system is configured to spread light from the LED modules outward when the plate has a convex curvature.

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.

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.

The present invention relates to an indoor aquaponics assembly which includes a base, an aquarium positioned above and supported by the base, a planter positioned above the aquarium, an aquarium conduit and a planter conduit. The planter is provided with at least two through holes facing towards the aquarium, one being adapted for a water drainage tube to pass through for draining water from the planter to the aquarium, and one being adapted for a tube of a pump to pass through for pumping water from the aquarium to the planter. The present invention aims at reducing the time and efforts required for caring and maintaining the aquarium and the plants.

An aquaculture luminaire (10, 12) generates below the water surface upward light (26) and downward light (24). The upward light (26) is all directed with an angle to the vertical greater than a threshold angle. The division of light between the upward and downward directions may be configurable. Alternatively or additionally, the threshold angle may be configurable so that it ensures the light exceeds the angle for total internal reflection at the water surface. In this way, the luminaire is adaptable to the intended installation position of the luminaire and/or the prevailing water surface conditions (e.g. waves).

The present invention relates to a method for inducing artificial hibernation of fish that is capable of transporting the fish in a state of being alive for long hours. According to the present invention, a water temperature is gradually decreased from an initial water temperature to the lowest water temperature, the fish are induced to the artificial hibernation, and they are packed in a waterless state. The packing is carried out in an environment where the lowest water temperature is constantly maintained, and a refrigerant is also packed to constantly maintain a temperature in a packing container, while oxygen is continuously supplied to the live fish induced to the artificial hibernation. The fish are individually packed in the Styrofoam box, and even if an atmospheric pressure in the airport is lowered during transport of the fish, there is no danger of causing respiration of the fish to be hard due to a plastic bag damaged. Through the hibernation inducing method and packing capable of reducing stress of the fish, in addition, the fish can be alive in a waterless environment for 36 hours or more, thereby making possible to globally distribute the live fish.
