Technical field

The invention relates to a factory pearl breeding equipment and a breeding method, and belongs to the technical field of pearl breeding.

Background technique

Pond culture is currently the main form of freshwater pearl culture in China and the main source of pearl product supply. However, pond culture is limited by land area and geographical conditions. It is difficult to control water quality, water temperature, salinity, bait and other breeding indicators during the breeding process. Excessive fertilization can easily cause serious pollution to the water environment, resulting in atrophy of the breeding area and poor pearl quality. Problems affecting pearl farming have arisen.

With the deterioration of the marine aquaculture environment, seashore tidal flats and shallow waters are no longer the only place to cultivate pearls. Factory cultured pearls are also a good option.

Chinese patent application CN201310386319.8 discloses a factory pearl culture system, which is composed of a pump house, algae pond, seawater filter pond, fresh water filter pond and pearl culture bead pond. Pearl oyster seedlings are placed in the pearl culture pond and passed through the pipeline. The filtered seawater that meets the salinity, pH and temperature of the seawater is injected into the pearl culture pond, and the seawater with seaweed is also injected into the pearl culture pond through the pipeline, and the pearl oysters are cultured with algae.

Chinese patent CN201320756818.7 discloses a factory-made freshwater pearl culture system, which includes a breeding pond, a water purification system, an electrolytic cell, a storage tank, an ozone generator and an oxygenator. The water purification system is a four-stage water purification system It includes a first water purification tank, a second water purification tank, a third water purification tank, and a fourth water purification tank.

Valves, filtering devices and return water pumps, the storage tank is also provided with a PH sensor, ammonia nitrogen value sensor, temperature sensor, pH value adjustment device, ammonia nitrogen adjustment device, temperature adjustment device. Achieve three-dimensional modular breeding in the breeding pond, but there are situations in which there is small movement space between multiple pearl mussels in each independent breeding frame and predation, etc., and it is not easy to observe the living status of each pearl mussel. Pearl mussels have lesions, and pearl mussels in other layers of the breeding pond unit are normal, which is likely to cause cross infection. At the same time, for the bottom pearl mussels, the sun cannot be exposed and the quality is affected.

Chinese patent application CN2015103551087 discloses a pearl culture device suitable for factory culture, which includes aeration device, sedimentation tank, microbial flocculant addition device, and purification tank, wherein a first filter screen is arranged near the central level in the culture tank, and Divided by a plurality of vertically arranged filter plates into a plurality of breeding spaces with upward openings, a pearl mussel is placed in each filter space, which makes full use of the space and does not cause the density of pearl mussels to be too high. It can be deformed correspondingly with the flow of water, reducing the stress it receives, and using nutrients in the water. However, it is precisely because the culture density of pearl mussels is low, and the breeding efficiency needs to be improved. There is also a small movement space between multiple pearl mussels in the same culture space and predation, which has an impact on the quality of pearls.

Therefore, by confining the pearl mussel in the corresponding breeding area, the pearl mussel can be prevented from contacting each other for predation and cross-infectious bacteria, thereby improving the breeding efficiency.

According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

According to a preferred embodiment of the present invention, the breeding pond has at least two layers, and the water outlet of the upper layer doubles as the water inlet of the next layer. Multi-layer breeding ponds can significantly increase the breeding volume per unit area. In order to facilitate the pearl clams in each layer of the breeding pond to be exposed to the sun, the two adjacent layers of the upper and lower layers of the breeding pond are staggered. The breeding pond is almost empty. In this way, the light-facing surface is formed to facilitate light exposure of the pearl mussel.

In order to make full use of the breeding space, the multiple breeding tanks in each breeding pond are divided into at least two layers, and the breeding slots of two adjacent layers are staggered. The dislocation arrangement can ensure that the pearl mussels can reach the sun, and it is also convenient to observe the activities of each pearl mussel and control the disease in time.

With the exception of the lowest aquaculture pond, each level of the aquaculture pond has a set of legs.
