Fish schools can also “graze” the future fisheries are facing changes

According to reports from the Russian High-tech News Network, biologists at the world-famous Woods Hole Marine Biological Laboratory recently used the latest biological interference technology to successfully develop a fish that can be "grazed" like a sheep. The fish can follow the sound or other signal and automatically swim to the specified area at the specified time; these fish can also eat a fixed share of food according to a fixed time and route, and then return to the fixed area, and the breeder can freely Grazing these fish.

According to reports, scientists used conditioned reflexes to train test fish at the beginning of the experiment. The fish population is placed in a larger area, but when feeding, scientists place the food in a fixed, narrow area to induce conditioned reflexes. However, scientists found that under the conditions of this conditioned reflex test, only part of the fish will produce conditioned reflexes for the purpose of testing, and most of the fish will not produce results. For this reason, scientists try to experiment with different methods. When scientists experimented with a black carp, they discovered that the sound signal could induce fish school.

Inspired by this phenomenon, the scientists carried out relevant biological interference tests on about a thousand groups of carp in six years, and finally obtained the test's success. The herring population has a very good response to the sound signals emitted by scientists and can perform various activities under the "signals" issued by scientists. Scientists believe that biological disturbances can enable fish schools to have a very good response and learning ability to sound signals from feeders. Under long-term interference with the biological growth of fish schools, fish schools can fully implement grazing management and breeding. . The keeper makes a sound signal and the fish react immediately. The researchers of the pilot project plan to combine this latest bio-interference technology with the latest RNA interference technology to change the genetics of fish so that the fish are as obedient as the sheep, and how much feed can be eaten by the breeder. Controlling, the breeder can even remotely control the growth and activity of the fish school. Scientists have now discovered the genetic features of bio-interference technology in the offspring of this group of carp. Some small carps have not undergone interference training but can also respond to sound signals.

At present, this project has received US$270,000 from the National Oceanic and Atmospheric Administration of the United States. The U.S. government has also funded some similar related research projects. American scientists believe that this technology has a revolutionary significance for traditional fishing. This grazing method can not only improve the efficiency of fishery production and save a lot of costs, but also has economic advantages compared with traditional fisheries, and if this bio-interference technology is successful in other livestock experiments, it will greatly change the tradition. The way of raising the agriculture greatly improves the production efficiency of agriculture and animal husbandry. It is reported that Japan has made large-scale investment in this grazing method and bio-interference technology. The scientists are ready to experiment further on other livestock.
