Description
Technical Field
The invention relates to the technical field of circular-mouth copper fish culture, in particular to a circular-mouth copper fish circulating water culture system.
Background
The round-mouth copper fish (Coreius guichenoti) belongs to the genus copper fish of the subfamily of the family cyprioidae of the order cyprinoidae, the special species at the upstream of the Yangtze river, belongs to typical river migration and drift-producing oofish, and is the main economic fish at the upstream of the Yangtze river. At present, natural population resources of round-mouth copper fish are seriously attenuated and the extinction risk is increasingly increased due to the influence of factors such as hydropower development, excessive fishing and the like. The method is characterized in that the artificial proliferation and release of the round-mouth copper fish is enhanced to be a necessary choice for protecting and recovering the resources of the round-mouth copper fish species group, and the artificial proliferation and release is realized firstly, the domestication survival and gonad development maturation of the round-mouth copper fish under the artificial culture condition is realized. The round-mouth copper fish has strong stress, high requirements on the culture environment, low artificial domestication survival rate and instability.
The current report about the domestication mode of the round-mouth copper fish is a Yangtze river hull net cage, a circulating water culture system and a controllable ecological pond. When the Yangtze river hull net cage is adopted for cultivation, the requirements on the place where the hull net cage is placed are high, diseases (especially melon insect diseases) can be effectively prevented only by arranging the hull net cage in places where water flow is relatively turbulent, and the survival rate is improved. The safety risk is also great in the Yangtze river hull cage culture process, especially in the flood season. In addition, the environment is affected in the Yangtze river cage culture process, so that the cage of the Yangtze river basin is completely removed due to environmental protection requirements.
The round-mouth copper fish belongs to the bottom fish, generally moves at the bottom of a water body under the domestication environment of the controllable ecological pond, and in addition, the area of the controllable ecological pond is generally larger (more than or equal to 3 mu), so that environmental indexes such as water quality, water temperature and the like are difficult to control accurately. Therefore, when the controllable ecological pond is used for domesticating the round-mouth copper fish, the situation that the round-mouth copper fish cannot be found in time due to diseases, abnormal activities and the like is caused, the environmental index is unsuitable, and the survival rate is influenced.
The circulating water culture system is a novel culture mode, and the cost generated in the culture pond is treated through a series of water treatment units and then recycled, so that the circulating water culture system has the advantages of environmental protection, water conservation, land conservation, strong controllability, low risk and the like, and has been successfully applied to the culture of marine fishes. However, there are two problems with existing recirculating aquaculture systems for the cultivation of round-mouth copper fish: (1) ozone addition sites are unsuitable: two types of relatively clear ozone adding positions exist in the existing circulating water culture system, namely, the ozone is added into a protein separator (only suitable for a seawater source and not suitable for a freshwater source); and secondly, a water quality regulating tank is added at the rear end of the water quality treatment unit, ozone is added into the water quality regulating tank, and as the water quality regulating tank is positioned at the rear end of the water treatment unit, the ozone addition amount is high, so that residues are easily caused, and the disinfection effect is affected by low addition amount. The water level regulating tank is added, so that the installation space is necessarily occupied, and facilities such as a water pump and a water supplementing device are added at the same time, so that the water flow balance in the circulating water culture system is kept, and the situation that water is lack or overflows from a certain device is avoided. (2) Partial culture water body is insufficiently sterilized and disinfected: in order to improve the oxygenation effect of the circulating water aquaculture system, oxygenation is generally carried out by adding pure oxygen through an oxygen cone, namely, pumping water into the oxygen cone through a water pump to be mixed with the pure oxygen, when the oxygenation is carried out by adopting the mode, the existing technology adopts two pipeline systems to feed water into an aquaculture pond (barrel) in order to keep the water flow balance of a certain device or the water overflow condition, namely, one pipeline system directly pumps the water of the water return groove (water collecting groove) into the oxygen cone through the water pump, and the water enters the aquaculture barrel after being oxygenated through the oxygen cone, and is not subjected to sterilization and disinfection treatment or even biological treatment.
