According to the China National Intellectual Property Administration, in March 2023, CAT AQUA declared that "a new type of crustacean aquatic animal breeding rack (patent number: ZL 2022 2 2949150.X)" and "a three-dimensional fish sunken egg incubation device (patent number: ZL 2022 2 2952154.3)" were officially granted utility model patents!
Two utility model patents, both aquaculture technology.
A new type of crustacean aquatic animal breeding rack is a drawer-type breeding rack independently developed for large-scale factory intensive culture according to the characteristics of crustacean aquatic animals sensitive to ammonia nitrogen. The equipment adopts an open drawer design, the bottom water inflow, the surface water overflow mode, the creatures placed on the bottom grid between the separated by adjustable partitions, strengthen the crustacean in the process of feeding and growth, the discharge of mucus, foam, and the bottom of the sewage outlet. This new type of crustacean drawer breeding rack not only realizes intensive breeding, improves breeding efficiency and product quality, but also reduces labor costs and facilitates personnel operation. It can be applied to various scenarios that require continuous large-scale production such as farms, modern laboratories, and catering enterprises.
Another three-dimensional fish sunken egg hatching device is a hatchery suitable for factory-scale aquaculture according to the characteristics of fish sunken egg hatching. The equipment adopts an open drawer design, a multi-layer layout of the vertical cabinet, adopts the mode of bottom water distribution and surface water overflow, the eggs are placed in the upper layer of the hatchery tray, and the fry hatched according to the habit can be drilled down into the lower layer against the direction of the water flow. The equipment significantly improves the hatchability of fish eggs and is a one-stop hatchery from egg hatching to eye-catching and then to larvae stage. It is suitable for various scenarios that require continuous large-scale production, such as farms, breeding centers, modern laboratories, value-added release stations, etc.
