Description

Incubation device of fish egg with automatic water level regulation and control function

Technical Field

The utility model belongs to the technical field of fish egg incubation, and particularly relates to a fish egg incubation device with a water level automatic regulation function.

Background

The aquatic product cultivation yield of China is more than 70% of the total aquatic product amount of China. The supply of fish fries is an important basis for the healthy and sustainable development of the aquaculture industry. At present, most of large-scale freshwater fishes can finish artificial breeding in a large-scale and commercial mode, and offspring seeds of the large-scale freshwater fishes can be stably and continuously supplied to the market. Most of the current designs of the aquatic hatching equipment are only suitable for hatching freshwater fish.

Along with the improvement of the living standard of people, the traditional fresh water aquatic products can not meet the demands of people on the aquatic products, and compared with most fresh water aquatic products, the sea water aquatic products have the advantages of less peculiar smell, rich nutrition and delicious taste, and are gradually favored by consumers; meanwhile, the development of the seawater aquarium industry increases the population pressure of wild seawater fish, and research on hot species artificial breeding technology is urgently needed. However, most of the sea water edible fishes and sea water ornamental fishes still need to be caught in the wild, taking the sea water ornamental fishes as an example, at present, only more than 30 sea water ornamental fishes which are artificially bred at home and abroad are realized, but the sea water ornamental fishes which participate in aquarium trade are as many as hundreds of sea water ornamental fishes, and the sea water ornamental fishes cannot be subjected to a large technical bottleneck of artificial breeding on a wide variety, namely lack of proper hatching and seedling raising equipment for carrying out the development of artificial breeding work. Compared with fresh water fish fries, the young fish fries of marine fish are weaker, weaker water flow, more oxygen-enriched water body and more stable environment are needed, so that an incubation device for fish eggs with an automatic water level regulating and controlling function is needed, the single fish egg incubation amount and incubation rate are improved, the fish fry damage in incubation and transferring processes is reduced, and the survival rate of the fish fries in the breeding process is improved, and the young fish fries are used for solving the problems of current high-value marine economy and artificial breeding of ornamental fish.

Most of hatching devices in the market at present are devices for hatching freshwater fish eggs, but most of freshwater fish eggs have large egg diameters and tough egg membranes, and the initially hatched fries are large, can independently swim and actively ingest exogenous nutrient substances, have good stress resistance and are insensitive to mechanical damage caused by external environment change and water flow. However, many sea water fish eggs, small parts of fresh water fish eggs and eel eggs are small in egg diameter and sensitive to external environment change, and the initial hatched fries are poor in stress resistance and poor in autonomous swimming ability, so that certain water flow environments are needed to assist in predation, and the fries cannot be damaged by excessively excited water flow. Meanwhile, most hatching equipment cannot bear subsequent seedling raising work, so that a great deal of loss is caused in the process of transferring some varieties after hatching, the success rate and the economic income of seedling raising workers are directly influenced, for example, chinese patent 201820754685.2, 12 months and 14 days of publication date 2018, discloses a device and a device for hatching heavy spawn fish fries, which comprise a hatching barrel, a water draining barrel, a porous plate, an aeration plate and a blower; the device utilizes the comprehensive effect of water flow and air flow to avoid the mutual adhesion of fish eggs and increase the oxygen solubility in water, thereby improving the hatching rate of the fish eggs; however, the device and the equipment use air flow for hatching, and the water flow speed cannot be accurately regulated, so that artificial hatching of fish eggs with smaller diameters is difficult to complete, and the water flow driven by air bubbles can also cause mechanical damage to the weak initially hatched fish. In view of the above, according to the shortcomings of the existing hatching device, there is a need for a fry hatching device with water flow driving, controllable flow rate, controllable water quality, integrated hatching and raising, and reduced mechanical damage of fries in a container, but no report has been made on such devices.
