Embodiment 1

[0038] In May 2008, Tianjin Xinyongfeng Aquaculture Co., Ltd. took the lead in using this method to carry out the culture experiment of semi-smooth tongue sole. The water source is heavy brine from Changlu Salt Field in Hangu, Tianjin, with a salinity of 40-60, 1 geothermal well at 1100m, outlet water temperature of 55°C, 4 shallow water wells, water temperature of 20-35°C. The water temperature of the breeding water is kept at 18-25°C all year round, and the salinity is 20-33. The utilization rate of aquaculture wastewater is 30%. The company grows 80,000 self-propagating half-smooth tongue sole seedlings (the ratio of male to female is about 1:1), and gradually eliminates male fish that have no commercial value during the breeding process. After 15 months of breeding, by December 2010, the average weight of the remaining about 40,000 female fish reached 1200g. During the breeding period, no disease occurs, and the survival rate is as high as 95%. Experiments have proved t...

Embodiment 2

[0040] In March 2009, Tianjin Shengyi Breeding Co., Ltd. began to use this method to carry out the culture experiment of semi-smooth tongue sole. The water source is heavy brine discharged from Tianjin Beijiang Power Plant, with a salinity of 80-100, one 1200m geothermal well with a water outlet temperature of 58°C, and 5 shallow water wells with a water temperature of 20-40°C. The temperature of the water for cultivation is kept at 18-25°C, and the salinity is 20-33. The utilization rate of aquaculture wastewater is 50%. The company breeds 100,000 semi-smooth tongue soles, and gradually eliminates male fish and slow-growing individuals during the breeding process. The total elimination rate in the breeding process is 60%. By September 2010, after one and a half years of breeding, the average weight of the remaining 40,000 female fish reached 1,500g. Experiments prove that the invention effectively solves the limiting bottlenecks such as unstable water quality, realizes ener...

Abstract

The invention relates to a novel farming method of cynoglossus semilaevis. A main mode is of a combined mode of a warmhouse booth, heavy brine, geothermal freshwater and liquid oxygen. The novel farming method specifically comprises the steps of: purifying a water source; conditioning water temperature and water quality; carrying out ultraviolet sterilization; carrying out high-efficient oxygenation; farming in a farming workshop; recovering farming wastewater; and enabling the recovered farming wastewater to enter into a distribution reservoir according to the proportion of 30%-50%, conditioning the water temperature and the water quality again and enabling the wastewater to enter into a farming pond. According to the novel farming method disclosed by the invention, the use of fire coal and a Roots blower can be stopped, the energy-saving effect is significant, and the farming risk caused by insufficient electric power is simultaneously reduced; and the problem that the farming of the cynoglossus semilaevis is limited in a plurality of regions with abundant heavy brine and geothermal resources and the insufficient supply of seawater, and the development of the farming industry of the cynoglossus semilaevis is benefited.

Description

Technical field: [0001] The invention belongs to the field of mariculture, and in particular relates to a complete set of new methods for cultivating tongue sole in greenhouses + heavy brine + geothermal fresh water + liquid oxygen. Background technique: [0002] In the 1990s, when the land-based industrial aquaculture of flounder and turbot in my country was developed on a large scale, along with the development of cages and industrial aquaculture of swimming fish, the first marine aquaculture in my country was formed. The four waves, that is, the cultivation of marine fish. After more than 20 years of development, a variety of marine fish farming models such as cages, industrialization, and ponds have gradually formed, among which industrial farming includes "greenhouse + deep well seawater", Xunhua water and other farming models. [0003] Semi-smooth tongue sole is a traditional rare fish species in my country. It has the characteristics of wide temperature and salt range...
