With the advancement of science and technology, industrialized fish culture technology continues to develop, and many countries have continuously made new achievements in increasing aquatic product output, reducing energy consumption, and saving water resources.
First, the use of closed-cycle aquaculture systems.
Due to the shortage of water resources in the world, developed countries are paying more and more attention to the development of closed-cycle aquaculture equipment, further improving water treatment technologies, and reducing the amount of daily water changes.
Second, increase oxygenation technology.
Countries such as Denmark and Germany have designed and built aquaculture equipment that uses liquid oxygen to increase oxygen in fish ponds and biofilters. This has greatly increased the fish production per unit of fruit. U.S. and Sweden and other countries have developed a pressure swing absorption system to produce oxygen, which can be used to directly produce oxygen enriched from 85% to 95% in fish culture, so that industrial farms can also use pure oxygen aeration technology.
Third, major progress has been made in water treatment.
The wastewater treatment of freshwater fish farming is still an important issue in the development of industrial fish farming technology. The pebble filters, drip pools, and active polluted mud pools that were developed since the 1970s have gradually been eliminated. In the late 1980s, closed biological filters, biological rotors plus triangular filters, and special biological rotors plus active contaminated mud and other water treatment equipment have strong vitality due to their small footprint and good treatment effect. Developed countries will develop new types of fishery sewage treatment equipment with small size, low cost, and strong ability to treat sewage according to the characteristics of their water treatment technologies.
Fourth, heat pump further popularization and application.
For industrial fish farming, controlling temperature is an important part. In the case of daily water changes of 8% to 10%, the heating fee is a considerable figure. The heat pump is a new type of energy-saving temperature control device, which can save about 50% energy than conventional temperature control devices.
Fifth, monitoring technology has been further improved.
At present, more advanced industrialized fish farming equipment uses computer-controlled sensing devices to collect and analyze relevant water quality data such as pH, oxygen content, water temperature, water level, and flow rate. And equipped with a corresponding alarm and emergency system. Some farms use television cameras to scan the water surface to obtain information on fish consumption, or use computers to arrange the best amount of feed. In addition, there will be breakthroughs in the rapid determination of important water quality data, such as ammonia nitrogen content and nitrite content, in order to monitor water quality more effectively.
