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;

[0023] ...

Abstract

The invention discloses a method for transporting and domesticating plateau fish seedlings. The method comprises the following steps of A, seedling selecting: selecting plateau fish seedlings obtained from fish production in plateau sections and artificial incubation by research and development institution or wild plateau fish seedlings caught in the field; B, long-distance transporting, wherein the transportation time is selected in spring or autumn; C, recovering after transporting: after arriving at the destination, putting fish seedling bags into a temperature control aquaculture barrel to balance water temperature, fishing out the fish seedlings after finishing disinfection, and transferring to the temperature control aquaculture barrel to be domesticated temporarily; D, daily domesticating: temporarily domesticating the fish seedlings in a closed recirculation water system, adopting ultraviolet light to disinfect circulating water, illuminating for 12L:12D, feeding for two times every day, cleaning residual feeds and faeces after feeding, and keeping the aquaculture water quality to be clean. The method is easy to be implemented, and is simple and convenient to be operated, high in fish seedling survival rate, stable in growth, and solves the difficult problem that the domesticating survival rate of the fish seedlings in the inland is low caused by the factors such as large altitude difference and temperature difference and long transportation distance when the plateau fish seedlings are transported to the inland regions and being domesticated.

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...
