Australian freshwater lobster breeding system

Abstract

The invention discloses an Australian freshwater lobster breeding system, and belongs to the technical field of aquaculture. A greenhouse shed support is arranged on the upper side of a lobster breeding pond; film covering adjusting mechanisms are arranged on the two sides of the upper portion of the greenhouse shed support correspondingly; a breeding pond heating boiler is fixedly arranged on a breeding pond base on the outer side of the greenhouse shed support; a heating annular pipe is arranged on the outer side of a heating combustion chamber in the breeding pond heating boiler in a sleeving mode; umbrella-shaped water distributors are fixedly arranged on the two sides of the lobster breeding pond; heating air guide pipes are arranged on the two sides of the end of an air outlet air guide pipe in a communicating mode correspondingly; tooth-shaped heating pipes are horizontally arranged at the ends of the heating air guide pipes in a communicating mode; a plurality of lobster inhabiting mechanisms are evenly arranged in the lobster breeding pond; and a breeding isolation net is vertically arranged in the lobster breeding pond. The system is reasonable in structural design, the water temperature of the lobster breeding pond can be efficiently and evenly increased, the lobster breeding inhabiting space can be effectively increased, the lobster breeding quality and breeding density are improved, and the breeding use requirement is met.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an Australian freshwater lobster cultivation system, which is mainly used in the Australian freshwater lobster cultivation field. Background technique [0002] The scientific name of Australian freshwater lobster is red claw crayfish. It lives in fresh water. In recent years, a large number of artificial breeding has been carried out. It is one of the best freshwater shrimps in the world. Compared with other shrimps, Australian freshwater lobster has more economic benefits in farming. It has many obvious advantages. The Australian freshwater lobster is large and thick. The average individual weight is 100g-200g, and the largest individual is more than 500g. It grows fast and has a high yield. It can be harvested in the same year and can be harvested in the same year. The output of fresh shrimp per mu can reach 300-500 kg. Left and right, Australian freshwater lobs...

Problems solved by technology

During the breeding process of Australian freshwater lobster, because it can grow rapidly at a water temperature of 25°C, in order to realize the rapid and high-quality breeding growth of Australian freshwater lobster and improve the economic benefits of Australian freshwater lobster farming, the existing Australian freshwater lobster in the Yangtze River Delta region Freshwater lobster farming is mainly done in greenhouses. The greenhouse used for Australian freshwater lobsters is mainly realized by covering the greenhouse bracket with plastic film. This kind of greenhouse has a simple structure and single function. The plastic on the greenhouse bracket It is difficult to automatically and conveniently cover and lift the film according to the ambient temperature. The plastic film on the greenhouse support is fixed and connected. The film covering and lifting of the plastic film are manually operated. During the operation process, the work intensity is high, and the operation efficiency of plastic film covering and lifting is low, and the connection and ventilation between the greenhouse and the external environment cannot be effectively adjusted. The coverage of the plastic film is adjusted. The heating method of the existing Australian freshwater lobster breeding greenhouse mainly adopts boiler heating, but the existing heating boiler mainly adopts water circulation heating to heat the breeding greenhouse, and the boiler heating produces The hot air is discharged to the external environment, so it is difficult for the existing aquaculture greenhouse to efficiently and fully utilize the heat energy generated by the boiler during the heating process, and it is difficult for the existing heating boiler to increase the water temperature of the lobster aquaculture pond. Efficiently and evenly dispersing the heat generated by the boiler in the lobster breeding pond, it is easy to cause uneven water temperature in the lobster breeding pond, local water temperature in the lobster breeding pond is too high and local water temperature is too low, it is difficult to achieve a uniform increase in the water temperature in the lobster breeding pond, which affects Australian fresh water The quality of lobster cultivation. In the process of cultivating lobsters in existing lobster cultivation ponds, Australian freshwater lobsters mainly inhabit the bottom of the lobster cultivation ponds and the banks of the lobster cultivation ponds. Therefore, for the lobster cultivation ponds per unit area, in In the case of ensuring the habitat density of Australian freshwater lobsters, the number of lobster breeding ponds per unit area is fixed, and there is no lobster habitat mechanism in the existing lobster breeding ponds, which cannot effectively increase the habitat space for lobster breeding, making it difficult to increase the number of lobster breeding per unit area , so the output of Australian freshwater lobster per unit area is fixed, it is difficult to effectively improve the economic benefits of Australian freshwater lobster farming, and cannot meet the needs of farming and use
