Embodiment Construction

[0041] In the following, the present invention will be further described through specific embodiments in conjunction with the accompanying drawings.

[0042] 1. Pond freshwater pearl mussel pond polyculture system

[0043] as indicated figure 1 As shown, the freshwater pearl mussel pond polyculture system includes: a pond (1), an isolation device (2), a pearl mussel polyculture area (3) and a fish intensive culture area (4). The water depth of the pond (1) is 0.7~3 meters, and the isolation device (2) is a seine or a net cage, which divides and isolates the pond into different cultivation areas on the plane: the polyculture area of ​​pearl mussels (3) and fish Intensive culture area (4); the isolation device can separate cultured animals such as fish and mussels in different areas to raise, and the cultured water body and microorganisms such as phytoplankton and zooplankton can be freely exchanged between each area, and the The isolation device encloses the fish intensive ...

Abstract

The invention provides a mixotrophic-cultivation system in a freshwater pearl mussel pond, which comprises a pond, a separation device, a pearl mussel mixotrophic-cultivation region and an intensive fish cultivation region. The invention also provides a method for cultivating the pearl mussel by the mixotrophic-cultivation system. The mixotrophic-cultivation system and the method make full use of the nutrition relation among the mixotrophic-cultivation species, which reduces nutrition collecting volume; by regulating water quality and water transparency as well as regulating composition of species of phytoplankton and biomass, nutrient salt, phytoplankton and level of dissolved oxygen of the water can be effectively and conveniently controlled, which can effectively keep a good ecological environment of the water. The mixotrophic-cultivation system and method of the invention can obviously accelerate growth of the pearl mussel and increment speed of the pearl.

Description

technical field [0001] The invention belongs to freshwater culture technology, and relates to a freshwater pearl mussel polyculture system and a polyculture method. Background technique [0002] Pearl is not only a noble ornament, but also a valuable traditional Chinese medicinal material, which has a high market value. With the development of social economy and scientific and technological level, the use of pearls has been continuously expanded, and the market demand is increasing. [0003] Artificially cultivated freshwater pearls have a long history in my country. At present, the species of pearl mussels used to cultivate freshwater pearls in my country are mainly triangular sail mussels. There are two main breeding modes for freshwater pearls: (1) Pearls that have undergone surgical insertion or core insertion are suspended in natural waters such as rivers and lakes. Mussels, cultivate phytoplankton as the natural bait of pearl mussels by artificially sprinkling organic...
