Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an aquaculture hatching device. Background Technology

[0002] Aquaculture hatching devices are specialized equipment or systems used for the artificial incubation of aquatic seedlings. They improve the hatching rate of fertilized eggs and the survival rate of larvae by precisely controlling environmental conditions (such as temperature, water quality, dissolved oxygen, and flow rate).

[0003] Existing incubation devices involve directly placing fertilized eggs into an incubation frame and then immersing the frame in a water tank. However, due to the lack of a support base at the bottom of the incubation frame, fertilized eggs tend to accumulate at the bottom, causing insufficient dissolved oxygen and leading to hypoxia and death. Furthermore, newly hatched seedlings lack suitable shelter and are prone to stress responses due to external disturbances, affecting their normal development and survival rate. Therefore, an aquaculture incubation device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aquaculture hatching device with the advantage of high hatching efficiency. It solves the problems of existing hatching devices lacking a base for attachment, causing fertilized eggs to accumulate at the bottom of the hatching frame, resulting in insufficient dissolved oxygen and thus leading to fertilized eggs dying from hypoxia. In addition, newly hatched seedlings lack suitable hiding places and are prone to stress reactions due to external disturbances, affecting their normal development and survival rate.

[0005] To achieve the aforementioned goal of high hatching efficiency, this utility model provides the following technical solution: an aquaculture hatching device, comprising a hatching tank, wherein the hatching tank is provided with a hatching mechanism; The incubation mechanism includes a support frame fixedly installed on the top of the incubation tank, an incubation net frame fixedly installed inside the support frame, a bottom plate fixedly installed at the bottom of the incubation net frame, and a plush rod extending into the incubation net frame fixedly installed on the surface of the bottom plate. The incubation tank is equipped with a water inlet and outlet mechanism.

[0006] Furthermore, a support plate is fixedly installed on the opposite side of the outer surface of the incubation tank. Two fixing slots are opened on the upper surface of the support plate. A fixing rod that matches the fixing slot is fixedly installed on the lower surface of the support frame. A handle is fixedly installed on the upper surface of the support frame.

[0007] Furthermore, there are multiple fluff rods, which are evenly distributed inside the incubation frame.

[0008] Furthermore, the water inlet and outlet mechanism includes a water inlet cover fixedly installed on one side surface of the incubation tank and connected to the inside of the incubation tank.

[0009] Furthermore, a plurality of diversion blocks are fixedly installed inside the water inlet hood. The plurality of diversion blocks are evenly distributed inside the water inlet hood, and the distance between two adjacent diversion blocks is equal. The shape of the diversion block near the end of the water distribution pipe is conical.

[0010] Furthermore, a baffle frame is fixedly installed inside the water outlet hood, and a filter bag located on one side of the baffle frame is snapped into the water inlet hood.

[0011] Compared with the prior art, this utility model provides an aquaculture hatching device with the following beneficial effects: 1. This aquaculture hatching device, by setting a sinking plate at the bottom of the hatching net frame, with multiple fluffy rods extending into the hatching net frame on the surface of the sinking plate, helps to provide attachment points for fertilized eggs, allowing the fertilized eggs to be evenly distributed and avoiding clumping together. This reduces the mortality of fertilized eggs due to lack of oxygen, improves the hatching success rate, and provides the seedlings with a hiding and resting space after hatching, reducing the interference of external environmental changes on the seedlings, reducing the stress response of the seedlings, promoting normal development of the seedlings, and improving the survival rate of the seedlings.

[0012] 2. This aquaculture hatching device features a support plate on the opposite side of the outer surface of the water tank.
