Embodiment Construction

[0038] This embodiment provides an address selection method for aquatic animal relocation protection, such as figure 1 shown, including:

[0039] (1) Divide the water area within the same river and within the preset threshold with the current protected area of ​​the target aquatic animal into several river sections.

[0040] In this example, the finless porpoise is used as the target aquatic animal, and the Zhenjiang finless porpoise protection area is the current protection area. The preset threshold is the farthest distance that the finless porpoise can migrate considering the transportation situation. In this example, the Yangtze River Basin from Zhenjiang to Nanjing is used to divide the river segment, a total of 19 points, such as figure 2 shown.

[0041] (2) Carry out target aquatic animal population monitoring and habitat surveys in each river section by means of on-site vessel surveys, and collect water environmental DNA samples at multiple points.

[0042] This st...

Abstract

The invention discloses an address selection method for aquatic animal ex-situ conservation. The method comprises the following steps: performing target aquatic animal population monitoring and ecological environment investigation on a river by adopting an on-site ship investigation mode, acquiring spatial distribution of target aquatic animals in the river by adopting an environmental DNA macro bar code technology, and selecting an area with more target aquatic animals as a to-be-determined area; further judging a genetic relationship between a target animal population in the to-be-determined area and target animals in an original area, wherein if the genetic relationship between the two populations is relatively close, basic conditions of ex-situ conservation are met; further constructing a habitat ecological environment suitability model, calculating ecological environment suitability, and selecting a place with the highest suitability as a target ex-situ conservation area. The invention is comprehensive in consideration, and the suitability of a selected migration address is higher.

Description

technical field [0001] The invention relates to an address selection method, in particular to an address selection method for aquatic animal relocation protection. Background technique [0002] With the development of the natural ecological environment or human intervention, the existing protected areas for many aquatic animals may no longer be suitable for the survival of aquatic animals, so they need to be relocated to find better habitats for protection. For example, the Yangtze finless porpoise (Noephocaena phocaenoides asiaeorientalis) is a freshwater dolphin endemic to China. As the only remaining mammal in the Yangtze River, the endangered level of the Yangtze finless porpoise has always been concerned by people. In 2013, the Species Survival Commission of the International Union for Conservation of Nature classified the Yangtze finless porpoise as "critically endangered", second only to extinction in the wild. In order to change the endangered situation of the finl...
