The use of specific color light to determine the growth of seedlings and fish is based on the “Basic Research on Specific Color Light Promoting Fish Growth†by Professor Takahashi Takahashi of the University of Kita, Japan. The resource-proliferation personnel of the Northeast Fisheries Research Institute affiliated to the Research Center, Professor Takahashi and the Industrial Stan Electric Co., Ltd. formed a research team to conduct mass production experiments using a 50-ton water tank. The team was in the disaster recovery area and the Ministry of Agriculture, Forestry and Fisheries. The study was carried out under the subsidy “Promoting the Regeneration of Disaster Areas – Development of Cutting-Edge Technologies for Food Productionâ€.
The experiment was carried out in July 2013. In addition to the natural light during the day, the stellar scorpion was irradiated with green LED light for 7 hours. It was found that the star scorpion, which was illuminated 3 months after the green LED light, grew from 10 cm in length. At 18 cm, the star that does not illuminate the LED light grows to only 16 cm in the same period, so the green LED light has a growth effect of more than 10% on the growth of the star. In addition, the star-shaped scorpion that only illuminates natural light grows from 18 grams to 55 grams in 3 months, and the star-shaped scorpion that illuminates the green LED light grows from 18 grams to 86 grams, which is more important than the natural light-grown star. 1.5 times more.
Before the mass production of livestock, the seedlings were first cultivated in the spring. It was also found that the seedlings with green LED light were 3 cm long and 8 cm long for 3 months. The seedlings using natural light alone need to grow to 8 cm but take 4 months. This discovery has contributed to the release of the business, because in the past, in order to match the suitable release time of natural waters, Japan used the method of increasing water temperature to promote the growth of seedlings during the intermediate cultivation. In the future, it is expected to use green LED lamps instead of heating to promote It grows into fry that is suitable for release, reducing the cost of warming.
In addition, in addition to the scorpion, the use of LED lighting is also known to promote the growth of other species, but different species of fish, the appropriate shades are different, the team is further research. The mechanism for illuminating with specific color light to promote growth has not been fully understood. Professor Takahashi, who conducted basic research in this field, said: "The growth of the star-shaped scorpion that illuminates the green LED light has not changed. It has only been found that in order to adapt to bright light, the color of the fish body shows changes in melanin agglutination hormone. A coagulation hormone has an appetite-promoting effect on mammals. For Xingyi, perhaps the exposure of green LED light can promote growth and is related to MCH?"
