Problems solved by technology

[0003] The purpose of the present invention is to provide a method for transporting and domesticating plateau fish fry, which is easy to implement, easy to operate, high in fry survival rate and stable in growth, and solves the problem of plateau fish fry transporting and domesticating inland. Unfavorable factors such as large altitude and temperature differences, and long transportation distances have caused the low survival rate of plateau fish fry to be domesticated in the interior

Embodiment 1

[0018] Example 1: Lhasa naked schizoriri fry were transported from Tibet to Wuhan for domestication test.

[0019] according to figure 1 As can be seen, a kind of plateau fish seed transportation and domestication method, its step is:

[0020] 1. Seed selection. Taking the artificial hatching of Lhasa naked schistos in Tibet as the selection object, selected individuals with no physical trauma and lively behavior as the transport test fish. A total of 1000 test fish were selected, and the size was 5-7cm in body length. Before transportation, the fry were kept in a circular cement pond (diameter 2.5m), fed with Shengsuo brand S series sturgeon compound feed, and fed twice a day (9:00 am and 4:00 pm).

[0021] 2. Long-distance transportation. Shipping options are in the fall.

[0022] (1) Packaging bag preparation: a plastic bag with a size of 15cm×86cm and a thickness of 0.8mm; when transporting, put two plastic bags together to form a double-layer packaging bag;

Abstract

The invention discloses a method for transporting and domesticating plateau fish fry. Steps: A. Seed selection: plateau fish fry obtained from plateau fish production and scientific research units artificially hatched or wild plateau fish caught in the wild B. Long-distance transportation: choose the transportation time in spring or autumn; C. Recovery after transportation: After arriving at the destination, put the fry bag into a temperature-controlled breeding bucket to balance the water temperature, and pick up the fry after disinfection. And transfer to the temperature-control breeding barrel and temporarily raise; D, daily domestication: the fish fry are temporarily raised in the closed circulating water system, and the circulating water adopts ultraviolet disinfection, and the light time is 12L:12D, and it is fed 2 times a day, and the residue is cleaned after feeding. bait and feces to keep the breeding water clean. The method is easy to implement, the operation is simple, the fry survival rate is high and the growth is stable. During the process of transporting and domesticating the plateau fish fry to the inland, it solves the problem of the survival rate of the fry in the inland domestication due to factors such as altitude difference and temperature difference, and long transportation distance. low puzzle.

Description

technical field [0001] The invention belongs to the technical field of fish transportation and domestication, and more specifically relates to a method for transporting and domesticating plateau fish fry. Background technique [0002] Plateau fish refers to fish living in high-altitude areas. In my country, it mainly refers to fish living in the Qinghai-Tibet Plateau region. The main species are Schizothorax subfamily fish, plateau loach and squid family fish. In recent years, with the intensification of human activities such as tourism and fishing, some plateau fish have experienced a trend of habitat destruction and resource decline. Therefore, it is necessary to carry out research on artificial domestication and breeding technology of plateau fish to protect and restore the natural population of plateau fish. However, plateau areas are often sparsely populated, with poor environmental conditions and weak scientific research capabilities. It is impossible to carry out art...
