Aquatic seedling domesticator and application thereof

Abstract

The invention discloses an aquatic seedling domesticator and application thereof. The aquatic seedling domesticator comprises a water tank, an automatic water feeding device arranged on the water tank, a stirring device, a drainage and pollution discharge device, a feeding and bait discharging device, phototaxis training devices and an anti-overflow drainage device, wherein the automatic water feeding device is connected with a water inlet pipe, water is added into the water tank, the stirring device is arranged in the middle of the water tank, the drainage and pollution discharge device is arranged at the lower end of the water tank, the feeding and bait discharging device is movably arranged on an upper top plate of the water tank, the phototaxis training devices are symmetrically arranged on the side walls of the two ends of the water tank in the length direction, and the anti-overflow drainage device is arranged on the side wall of the water tank in the width direction and communicates with a water outlet pipe of the drainage and pollution discharge device. When the aquatic seedling domesticator is used, seedling phototaxis clustering training can be carried out through light conversion, material training is facilitated, the survival rate after seedling throwing can be effectively guaranteed, aquatic seedlings can be well domesticated through the aquatic seedling domesticator, and the aquatic seedling domesticator has the advantages of being easy and convenient to use and facilitates domestication.

Description

technical field [0001] The invention belongs to the technical field of aquatic equipment, and in particular relates to an aquatic seedling domestication device and its application. Background technique [0002] Under natural conditions, aquatic seedlings feed on natural bait, such as algae, rotifers, cladocerans, copepods, etc., but it is difficult to domesticate from natural bait to artificial bait. Apparatus and methods. The scientific name of the California perch is the largemouth bass (Micopterus salmoides), which is native to North America and belongs to the family Perciformes, Sunfish family, and Perch genus in taxonomy. It is a typical carnivorous freshwater fish and the most important game fish in the United States. One; it was introduced from abroad in the 1980s and achieved success in breeding and breeding. In recent years, it has been favored by farmers and the market, and the scale of breeding has become larger and larger. [0003] At present, domestic aquatic ...

AI Technical Summary

Problems solved by technology

Manual feeding of seedlings is prone to uneven distribution, and the simple baiting machine is cumbersome to operate, which can only be replaced by artificial feeding for a short time, and cannot be completely domesticated by the feeding machine;

[0004] Under natural conditions, aquatic seedlings are generally bred in seawater. In order to carry out artificial freshwater aquaculture of aquatic products, the seedlings must be desalinated before breeding. At present, there are two main methods: direct desalination in large ponds and centralized desalination in factories; direct desalination in ponds Desalination has disadvantages such as low survival rate, difficult timing of release, and salinization of the pond bottom. Compared with it, centralized desalination of shrimp seedlings has the advantages of reducing stress, convenient transportation and release, and high survival rate of shrimp seedlings. The main method of desalination of aquatic seedlings; however, at present, the centralized desalination seedling cultivation in aquatic seedling factories almost all use indoor cement pools as cultivation devices throughout the whole process. Consignment from coastal provinces to the inland is costly; in addition, when the water body is large in volume, the water quality regulation during the desalination process, including temperature control, gradual desalination of salinity, and slow removal of harmful substances in the water, are not suitable for timely control and fail. The risk is higher. At the same time, because of the large area, the acclimatization time of the early opening bait for aquatic seedlings is relatively long, and some seedlings cannot supplement food nutrition in time, which affects the early adaptability of the seedlings, and the survival rate is reduced or unstable.

[0005] In summary, the present invention needs to solve the problem of adopting indoor cement pools as cultivation devices in the cultivation process of concentrated desalination aquatic product seedlings in shrimp fry factories, resulting in a large amount of sea crystal usage and high cost of consumables. Adjust the water quality, maintain a good breeding water environment, cannot speed up the speed of domestication in the early stage of desalination, and supplement nutrition in time, the survival rate is low, the cost and risk of breeding are relatively high, etc.
