The device comprises an incubation frame; the multiple incubation boxes are all arranged at the bottom of the incubation frame, and drainage pipes are fixedly installed on the front faces of the multiple incubation boxes. According to the batch artificial incubation equipment and method for the ricefield eel fertilized eggs, the incubation frame, the multiple incubation boxes, the water supply assembly, the water supply pipeline, the air supply pipeline, the multiple fixed pulleys, the steel cable, the multiple incubation barrels, the driving assembly and other structures are matched with one another, and the water supply assembly and the water supply pipeline provide a stable constant-temperature water source for the incubation boxes; the air supply pipeline ensures sufficient dissolved oxygen in the water body; the driving assembly drives the hatching barrel to reciprocate up and down through the steel cable and the fixed pulley, oosperm adhesion is avoided, frequent manual intervention is not needed, the problems that natural hatching water temperature is unstable, and water mold infection is prone to occurring are solved, batched hatching of ricefield eel oosperms is achieved, and the hatching success rate and the large-scale production efficiency are improved.

The invention relates to the technical field of aquaculture, in particular to a hippocampus kelloggi larva zoozoonosis prevention and treatment method which comprises the following steps: adding formalin for soaking for 12 hours on the first day, and then running water every other day; on the third day, formalin is added for soaking for 12 h, and then water flows for one day; on the fifth day, formalin and methylene blue are added to be soaked for 12 h, and then water flows for one day; respectively adding thioether floxacin on the seventh day and the eighth day, and standing; according to the method, insect killing, mildew prevention and sterilization are combined, parasites such as synechozostomia can be killed, secondary infection such as water mildew and bacteria can be prevented, the survival rate of the seahorse fry within 20 days old is remarkably increased, and the breeding efficiency is improved.

The invention discloses a crayfish egg counting, screening and hatching device based on image recognition, relates to the technical field of crayfish breeding, and aims to solve the problems that at present, a traditional artificial hatching facility for crayfishes has many defects, a container is tedious to mount and dismount, hatching efficiency is low, and the intelligent level is low; the technical problems that water treatment is single, oxygenation is insufficient, dirt causing water mildew cannot be cleaned in time, water quality is prone to being polluted, the hatching survival rate is low, and the production risk and cost are increased are solved, and the device comprises a screening mechanism and a hatching mechanism. Three different drainage modes are provided, so that the device can be selected in a diversified mode, breeding personnel can flexibly adjust the drainage modes according to actual requirements such as the development stage of the crayfish eggs, the water quality condition and the environmental condition, various requirements of crayfish egg incubation are better met, and the breeding efficiency is improved. The hatching process is accurately controlled and managed, the stability of water quality is guaranteed, the embryo is prevented from being impacted, and the hatching success rate is effectively increased.

This invention discloses a crayfish egg counting, screening, and hatching device based on image recognition, belonging to the field of crayfish breeding technology. It aims to solve the technical problems of current traditional artificial crayfish hatching facilities, including numerous drawbacks such as cumbersome container installation and disassembly, low hatching efficiency, low level of intelligence, and limited water treatment methods, insufficient oxygenation, and untimely cleaning of mold and debris, leading to water pollution, low hatching survival rates, and increased production risks and costs. The invention includes a screening mechanism and a hatching mechanism. This invention provides three different drainage methods, allowing for diverse selection. Farmers can flexibly adjust the drainage method according to actual needs, such as the developmental stage of the crayfish eggs, water quality, and environmental conditions, to better meet the various needs of crayfish egg hatching. This enables precise control and management of the hatching process, ensuring stable water quality while avoiding impact on the embryos, effectively improving the hatching success rate.

The invention discloses a multi-dimensional repair regulation and control method for improving soft-shelled turtle meat quality, which is characterized in that fasting and micro-nano bubbles are cooperatively regulated and controlled, and salinity and temperature are cooperatively regulated and controlled. According to the soft-shelled turtle feed, the meat structure of soft-shelled turtles is remarkably improved, the meat becomes soft, tender and elastic, the content of polyunsaturated fatty acid is remarkably increased, the palatable taste is remarkably improved, emptying of the soft-shelled turtles is promoted, fishy smell and peculiar smell are remarkably reduced, saprolegniasis of the soft-shelled turtles during temporary culture is effectively prevented, and the body health of the soft-shelled turtles is improved.

The invention belongs to the technical field of nuclear medicine, and particularly relates to a water mold shaking device and a water mold preparation method, and the water mold shaking device comprises a clamp configured to limit a water mold used for nuclear medicine equipment calibration in a state of being relatively fixed with the clamp; and the driving mechanism is in transmission connection with the clamp, and the driving mechanism is used for driving the clamp to move in a mode that the at least two substances in the water mold limited in the clamp can be fully mixed. The water mold is reliably fixed through the special clamp, and the drive mechanism automatically drives the clamp to move according to a preset track and parameters, so that the problems of radiation potential safety hazards and uncontrollable mixing quality existing in manual shaking are fundamentally solved; the operation safety is obviously improved, the efficiency is improved, the uniform distribution of the radioactive liquid is ensured, the standardization of the uniform shaking process is realized, and the universality of the device to different calibration scenes and the repeatability of the preparation result are enhanced.
