Abstract: Methods and systems are provided to insect harvesting. The system may include a tank for holding or growing live insects or both. The tank has an opening on a side portion of the tank, and the opening is positioned higher than a bottom portion of the tank. A negative stimulus device for repelling live insects toward a first direction or point towards the opening on the side portion of the tank is provided. A positive stimulus device is provided, situated at the opening of the tank. A product box for receiving live insects has an opening for receiving the live insects. A slide is coupled with the opening of the product box. In an operative position, the tank is positioned such that the live insects leaving the opening of the tank move down the slide to the opening of the product box.

Abstract: A washing bucket has a container with an interior defined by wall and a bottom, a fluid inlet affixed to the wall of the container and communicating with the interior of the container, and a fluid outlet opening to the wall of the container and positioned at a level higher than a level of the fluid inlet. The fluid inlet is positioned adjacent to the bottom of the container. The fluid inlet has a connector positioned exterior of the wall of the container and adapted to connect to a water hose. The fluid outlet has a diameter greater than a diameter of the fluid inlet. The fluid outlet has a pipe affixed to the wall of the container.

Abstract: An apparatus for washing meat or produce includes a container having an interior volume defined by wall and a base, and a pipe having an outlet opening to the interior volume of the container and an inlet at an exterior of the container. The container has an opening at an upper end thereof. The outlet opens adjacent to the base such that a flow of the fluid through the pipe is directed toward or adjacent to the base. The flow of water is directed through the container so as to create a circular flow pattern that causes the debris separate from the meat or produce within the container. A handle is affixed to or formed with the container on one of the end walls of the container.

Abstract: Cysts, in particular Artemia cysts, are incubated the in a hatching medium so that a portion of the cysts hatch and release free swimming live food organisms. The free swimming live food organisms have subsequently to be separated from the cysts which have not hatched. Before incubating the cysts, magnetic particles are applied onto the cysts so that these cysts can be attracted magnetically, in particular in the liquid hatching medium. This enables to separate the unhatched cysts and the empty cyst shells, coated with the magnetic particles, effectively from the free swimming live food organisms which do not have magnetic particles applied onto their outer surface. The invention also relates to the coated cysts.

Abstract: A method of artificially rearing lobster larvae, in which lobster larvae of the Palinuridae and Scyllaridae families are guided toward jellyfish so that the lobster larvae parasitize the jellyfish and grow on the host jellyfish. An apparatus for rearing lobster larvae wherein a symbiotic feeding tank (1), in which the larvae are reared in the state of being parasitic on the jellyfish, and a jellyfish rearing tank (2) are connected together via a pipe (3), through which water and the jellyfish are supplied from the jellyfish rearing tank (2) to the symbiotic feeding tank (1), and the pipe (3) is provided with a switching valve (7).

Abstract: The collector habitat device comprises panels of non-biodegradable and/or synthetic fibrous material set in durable weatherproof frames and attached to a base; when placed in, the panels hang within the water column providing numerous parallel settlement surfaces for post-larvae. A float assembly, optionally attached to the opposite side of the base from the panels, allows the device to float just below the water's surface. The collector habitat device also incorporates a guard, surrounding the panels, with apertures to allow settlement-stage post-larvae access to the settlement surfaces, while preventing larger organisms and potential predators from gaining access. The collector habitat device also, optionally, incorporates an optionally removable/re-attachable reservoir hung below the guard; and an optional olfactory attractant delivery device.

Abstract: A breeding tank comprising at least two dish-like breeding tubs each having a breeding space and each having a tub bottom and an opening surrounded by a periphery of a top of each of the dish-like breeding tubs, the tub bottoms of all the dish-like breeding tubs are arranged in a mutually vertically stacking mode, and the opening of each lower dish-like breeding tub is larger than that of its-upper dish-like breeding tub, all the dish-like breeding tubs are made of transparent material except the lowermost dish-like breeding tub. The present invention thus can make multiple vertically stacking breeding spaces in a limited space for breeding aquatic animals such as fishes, shrimps and crustacea etc.

Abstract: A scalable fish rearing raceway system is provided, incorporating a fish containment structure having two semi-circular end sections, and two or more parallel fish raceways, surrounding a central zone for housing water treatment systems and a secondary fish crop. Heavy particulates are eliminated from the main fish rearing channels by use of conical areas located at either end of the parallel elongated raceways. Continuous removal of dead or dying fish from the raceway is accomplished by means of a floating mortality catcher consisting of a screened ramp at the surface of the cones which continuously collect moribund and dead fish. Grading bars separate and move fish underwater to an adjacent raceway through a common fish transfer channel. This larger scalable fish production system substantially reduces the direct labor and capital costs associated with the production of fish as compared with conventional circular fish rearing tanks.

Abstract: Incubation device (10) has a structure wherein an incubation tank (11) and a separation tank (12) are put into communication with each other at the lowermost parts via a narrow communicating port (13). A side opening (14) is formed in the separation tank (12). The wall of the lower part of an upper housing part (12a) and of the entirety of a lower housing part (12b) of the separation tank (12) are formed from a colored, light-shielding material OP. Sea water (D) is housed in incubation tank (11) and the lower part of separation tank (12), freshwater (E) is housed in the upper part of the separation tank (12), and an interface (F) between the sea water (D) and the freshwater (E) is formed inside the separation tank (12). Brine shrimp larvae (2) hatch in the incubation tank (11) and upon moving into the separation tank (12), move from the light-shielded lower part towards the unshielded upper part and eventually swim outside into an aquarium tank from the side opening (14).
