In winter aquaculture, it is a good way to raise the temperature and increase the output without additional cost.

In traditional aquaculture, some tropical economic aquatic products and some other special aquatic products have higher requirements for water temperature and environmental temperature. Seedling production needs to raise water temperature to ensure the temperature growth of farmed varieties. In the past, farmers could only use kerosene boilers to heat the water or raise the ambient temperature, which consumed a lot of conventional energy and caused carbon dioxide emissions. With the rise of fuel prices, the costs of aquaculture farmers rise, profits decline, restricting the healthy development of the industry. Using solar energy to culture can solve the problem of fuel consumption in the process of traditional aquaculture, which will be a new direction of industrial development, using advanced technical means such as vacuum heat preservation, heating and circulating seawater, to meet the water temperature requirements of factory warm water aquaculture and seedling production in winter, and speed up seedling hatching. Huayuan New Energy's patented solar water heating system for seawater breeding and breeding is a solar water heating control device, which mainly includes a heat collection system, a control system, a heat exchange system and a seedling cultivation pond. it is mainly used for heating water supply in enterprise breeding and breeding production. The solar energy breeding and breeding heating system mainly relies on the solar collector to absorb sunlight, generate heat energy feed water heating, and cycle in turn. The use of solar energy heating in seedling production has the advantages of low cost, no pollution, automatic control and prolonging seedling culture time, so as to increase the yield of artificial seedling production and ensure the heating of seedling production and the need of domestic water for workers at the same time.

At the Haikou meeting, a professor said that the relevant research they had done was still very economical and practical-- the idea was good and difficult to popularize. The degree is not too high. Otherwise, seedling abnormalities [ts] babeone29 will add the following at 14:17 on 2009-11-16 [/ ts] heating is easy to distinguish, heating cost should also be included, and the temperature should not be too high. Otherwise, the shrimp fry will be deformed-this post was finally edited by hyne587 at 16:09 on 2009-11-16. Hehe, there are too many worries upstairs. Our technical research and development personnel have already considered this area, and it must be the right water temperature. The technology is good, but it is estimated to be difficult to popularize. Do you need the assistance of other heat sources? Will bad weather such as rain and snow affect solar energy? Ours is a patented "ecological water" technology. The so-called ecological water is a friendly temperature suitable for the growth of fish fry at a water temperature of 28 degrees. The technicians who developed this patent are all veteran engineers who graduated from Ocean University in the 1980s. Of course, auxiliary energy is needed, which can be used when it is cloudy and rainy. At present, the promotion is still in some large-scale modern enterprise management of breeding companies, private farms should also be gradually applied in the future. It also depends on policy support. -- it's good to learn plastic film to cover it. It's good to note that the circulating cooling water of DO-- thermal power plant is more economical and better. It's a way to heat up, but isn't the investment huge? Can the average user afford it?
