Stereoscopic fish and mussel polyculture method

Abstract

The invention discloses a stereoscopic fish and mussel polyculture method, and belongs to the field of fish and mussel polyculture. The stereoscopic fish and mussel polyculture method includes the following steps: S1: sterilizing a pond with the water depth of about 2 m through quicklime by a dry method and according to the quicklime consumption of about 75-100 kg per mu, feeding organic fertilizer as base fertilizer into the pond according to the amount of 1000 kg per mu after the effect disappears 1 week later, and adding water until the water depth reaches 1 meter. The stereoscopic fish andmussel polyculture method has the advantages that fishes and pearl-bearing mussels can be separated through net cages to be cultivated in the same pond, so that water resources are utilized stereoscopically, the food chain structure of aquatic creatures is improved, the utilization rate of baits is increased, the economic benefits are greatly increased, and ecological treatment of water pollutionis realized; the net cages include an inner net cage and an outer net cage, dense sections and sparse sections are arranged on the inner net cage and the outer net cage to communicate water bodies inside and outside the net cages, and accordingly, the pearl-bearing mussels are not likely to die of anoxia in the net cages.

Description

technical field [0001] The invention relates to the field of polyculture of fish and mussels, and more specifically, relates to a three-dimensional polyculture method of fish and mussels. Background technique [0002] A pearl is, in several species of molluscs, a dense concretion formed as a result of the aggregation of layers of nacre in or under the mantle around a foreign particle not attached to the shell, having various shapes but most typically round and pear The shape presents various colors, but it is usually white or light-colored, and has different degrees of luster, which can be used as decoration or medicine. As the demand for pearls increased, people began to cultivate pearls artificially. [0003] At present, only placing pearl-growing mussels in the pond is not conducive to the full utilization of bait and water resources in the pond. Therefore, a method of polyculture of fish and mussels has appeared in the existing life, but the existing process of polycult...

Problems solved by technology

[0003] At present, only placing pearl-growing mussels in the pond is not conducive to the full utilization of bait and water resources in the pond. Therefore, a method of polyculture of fish and mussels has appeared in the existing life, but the existing process of polyculture of fish and mussels requires The net cage is used to protect the pearl mussels so that it is not easy to hinder the fishing operation. After the net cage is used for a long time, the mesh of the net cage is easily blocked by adhesion. If it is not cleaned in time, it will easily cause the water inside and outside the net cage to be disconnected. , resulting in the death of pearl mussels in the cage due to lack of oxygen
