Description
Technical Field
The invention belongs to the technical field of transportation devices, and particularly relates to a transportation device for fertilized eggs of hucho taimen.
Background
Hucho bleekeri belonging to Hucho of Salmonidae of Salmoniformes, Hucho is named as Hujia fish, Changjiang Hucho taimen, and Belchou Hucho; local custom name: cat fish, tiger fish (Sichuan, Qinghai) and striped fish (Shaanxi) and the like belong to the special large-scale salmonidae fish at the upstream of the Yangtze river, are also the only large-scale native salmonidae fish in the Qinghai-Tibet plateau area, are national class I protected animals, and are listed in the class I fish priority protection category list in the Chinese biodiversity protection plan proposed in 11 months 1992, and are listed in the fourth place next to white sturgeons, Chinese sturgeons and Dahurian sturgeons; the hucho taimen, Chuanshan hucho salmon, published in 1998 as the endangered species and in red book of endangered animals, 2004 as the red famous records of Chinese species.
The hucho taimen is the soutest distributed type of 5 fishes in hucho genus, is diffused from the north when the climate is cold in the period of the fourth glacier, is left in rivers with higher altitude and lower water temperature after the ice period is over, is a typical land-sealed type fish, and has important academic value in the aspects of researching animal geography, ancient ecology, fish system evolution, climate change and the like. Hucho taimen are historically distributed in Sichuan (the great river and Minjiang river upstream and tributaries), Qinghai (the Makohe) and Shaanxi (the Hanjiang upstream tributaries are the white river and the xu water river), and the like. Since the 60's of the 20 th century, the population number has decreased dramatically due to climate change and human activities, and it is now difficult to collect samples in multiple historical distribution areas.
The hucho taimen protohabitat is in a high-altitude mountain area, water flow is rapid, water quality is clean, and the hucho taimen protohabitat is violent in character, the death rate of hucho taimen obtained by wild fishing is extremely high (the death rate reaches over 90% no matter the size of an individual, the larger the individual is, the higher the death rate is), and the hucho taimen prototrophic method is difficult to domesticate, and it is difficult to domesticate to obtain synchronously developed and mature female and male parent fishes.
At present, the artificial propagation work is carried out on the wild hucho taimen in the unmanned area of the foot-wood foot river upstream of the Yangtze river basin, and fertilized eggs are successfully obtained. The condition required for the development of fertilized eggs of hucho taimen is harsh, and after 4 months each year, the podophyllum and the podophyllum enter the flood period, so that the water body is turbid, artificial equipment cannot be adopted for on-site incubation in an unmanned area, or the on-site incubation can cause extremely low incubation rate; in the remote hatching, because the roads of the unmanned area are rugged and the mountain is steep, the fertilized eggs can be transported only by means of human backs or horse carrying, the fertilized eggs are transported to a suitable place, the stability of the fertilized eggs is ensured in the transportation process, and the environmental limitation factors such as vibration, illumination and the like are avoided, so that the remote hatching becomes an important measure for improving the hatching rate. However, the current fertilized egg storage device is generally difficult to meet the requirements.
