Abstract

The invention provides a crab-mandarin fish-xenocypris composite ecological cultivation method for soda type salinization reed swamp wet land, which comprises seeding domestication, released density and cultivation management, catching and fostering. The seeding domestication survival rates (%), the average released densities (pieces / hm<2>), the average released specifications (pieces / hm<2>), the average released weights (kg / hm<2>) of the crab, the mandarin fish and the xenocypris are respectively as follows: 1) 87.7%, 86.4% and 79.2%; 2) 1450,190 and 420; 3) 5.4,25.7 and 83.2; and 4) 7.83,4.88 and 34.94. The average catching densities ((pieces / hm<2>), the average catching specifications (pieces / hm<2>), the average catching weight (kg / hm<2>) and the average recapture rates of the crab, the mandarin fish and the xenocypris are respectively as follows: 1) 479,136 and 228; 2) 165.5,289.3 and 257.1; 3) 79.25,39.30 and 58.60; and 4) 33.0,71.6 and 54.3.

Description

technical field

[0001] The invention belongs to the technical field of aquaculture in saline-alkali wetlands, and relates to a method for compound ecological cultivation of "crab-mandarin fish-polocarp" in soda-type salinized reed swamp wetlands. technical background

[0002] On the premise of ensuring that the structure and function of wetland ecosystem are not destroyed, exploring the theory and practice of its rational use is one of the key topics of wetland scientific research in my country and even in the world. Wetland is one of the main types of land resources in my country. According to the difference in water quality and salt content, wetlands can be divided into freshwater wetlands and saltwater wetlands. Saltwater wetlands are mainly distributed in coastal and inland arid and semi-arid areas. Reed swamp wetland is one of the main ecological types of inland wetlands. According to the classification system specified by the International Convention on Wetlands, it b...
