A computer aquarium mounting structure includes an aquarium with water, wherein, a through hole is provided on the side wall of the aquarium, a motor case is installed on the outer wall of the aquarium, a computer motherboard is provided inside the motor case, a radiator is provided inside the aquarium, and the radiator is sealingly provided at the through hole, a CPU and/or a graphics card installed on the computer motherboard contact with the outside of the radiator. The disclosure can combine the aquarium with the computer organically, which can not only cool the computer through the aquarium, but also create a real sense of the desktop natural landscape. Moreover, it doesn't take up more space on the desktop, and doesn't make any noise because a fan will not be needed.

A coral holder which either resides in an aquarium or in a transport container. The coral holder may be either a fixed object or an insert. The coral holder has one or more coral channels, preferably elongated channels, which accept corals or coral plug(s) held securely in place anywhere along the channel(s) until the user desires to adjust or remove the coral plug.

A system and method for shrimp aquaculture is disclosed. All growth phases and essential operations are modularized and integrated in a system controlled by a cyber-physical platform. The system comprises one or more post-larvae nursery module(s), grow-out production module(s), recirculating aquaculture system (RAS) module(s), feed distribution module(s), and regulatory elements comprised of Program Logic Controllers (PLCs) integrated with Human Interface Modules (HIMs).

An adhesive composition may be applied to a surface, such as plastic, metal, wood, stucco, plaster, brick, concrete, glass, rubber, tile, fiberglass, ceramic, porcelain, canvas, stone, or drywall. The adhesive-containing surface is then pressed into contact with a second surface to create a strong, watertight bond. The methods disclosed herein may be used to assemble and/or repair a variety of articles and structures, such as roofs, gutters, boats, kayaks, personal watercraft, canoes, rafts, inflatable articles such as toys, sporting equipment, and air mattresses, outdoor equipment, mobile homes, recreational vehicles, campers, garden hoses, low-pressure PVC and plumbing pipes, tents, vinyl awnings, covers and tarps, swimming pools, windows, doors, walls, seams, vents, air ducts, HVAC systems, and the like. Also disclosed herein are methods of testing the bonding strength of an adhesive, methods of affecting underwater repairs, and methods of assembling an all-terrain vehicle.

The disclosure relates to the technical field of aquaculture, and more particularly to a fish breeding device provided with a magnetizer and a method for accelerating normal propagation and growth speeds of fishes. The fish breeding device includes a box body, a controllable partition plate, an extraction pump, and the magnetizer; the controllable partition plate is arranged in the box body and used for dividing the inner space of the box body into a feeding area and a non-feeding area; the extraction pump is arranged on the controllable partition plate and used for exchanging the water body in the feeding area with the water body in the non-feeding area; the magnetizer is arranged on the outer wall of the box body corresponding to the feeding area, and used for magnetizing the water body of the feeding area. In the disclosure, fish eggs are further hatched by the magnetized water. An adjustable magnetic field is utilized to act on fishes in development so that the fishes normally propagate and grow without causing the problems of retarded embryo development, stagnation, deformity, and the like. Meanwhile, pollutants generated in a feeding process can be purified, the utilization rate of feed put in a breeding process is increased, intermittent magnetization is adopted, and the consumption of electric energy is reduced.

The invention relates to a recirculating culture system for cultivating and/or breeding aquatic creatures, comprising: a recirculating system for circulating and controlling the temperature of a fluid, wherein the recirculating system has a culture pool (1) for receiving the fluid, a water reservoir (2) for storing the fluid, a temperature-control device (3) designed to supply thermal energy to and/or remove thermal energy from the fluid, a pump system (4) for circulating the fluid, and a filter system (5) for filtering the fluid; as well as a container (6) having at least one internal space (61), wherein the recirculating system is arranged in the at least one internal space (61) of the container (6).

A test device for noninvasive testing of fish habitat selection and application thereof is described herein. The device includes a camera device, a water circulating system, a fish transporting barrel, and a test water tank. The fish transporting barrel is a water barrel with an openable bottom. The central area of the test water tank is arranged as a closed adaptation area, a water outlet is formed in the bottom of the adaptation area. Fish passages are formed in the adaptation area. Test areas with equal sizes are formed around the adaptation area through partition plates. A water inlet is formed in each test area. Water flow buffering plates are arranged corresponding to the water inlets. Fish passages are formed in the bottoms of the partition plates of the test areas. The water inlets of the test areas are connected to the water circulating system.

A tank for water has a bottom and a surrounding wall with an inside and an outside. In a lower portion, the wall is provided with a hatch casing positioned in a hatch opening extending through the wall for access by personnel from the outside to the inside of the tank. The hatch casing is provided with a hatch with an inside and an outside. The hatch in a closed position closes the hatch opening in a liquid-tight manner. The inside of the hatch is flush with the inside of the wall when the hatch is in the closed position. A method for giving personnel access to the tank through the hatch opening is also described.
