When And How Was Fish Cage Farming Initially Invented? Surprising Truths Reveal!

Fish cage cultivation has been so much popular in 2019. It seems to be the most cutting edge technology just uprising within these 5 years. Actually, it is not as new and latest as most people expected. Do you know that there are actually over 160 years old for cage farming? Initially it was invented not for cultivation? In this blog, we are going to review global cage farming development for the past 160 years. At the end of this article, we shall also reveal the most developed country for cage cultivation nowadays. Cage farming was initially invented for temporarily keeping fishes alive. It was firstly invented in Kampuchea. Since 1851, now it has a history of at over 160 years. At that time, Kampuchea transportation mainly depended on the waterway, due to backward technically and economically conditions. Many fishermen near the Mekong River were living by fishing. When they caught a certain amount of fishes, they would transport to the golden border and other places to sell. By feeding fishes small baiting, people found that the fishes could grow rapidly. And they can sell the fishes at higher prices. Then the cage culture was spread from India River to the countries of Southeast Asia. By the time, it was already 20s and 30s of twentieth century. The fish cage culture was a traditional culture form in Kampuchea. The Mekong River was the birthplace of cage fish. At present, floating nets have been well developed in the Mekong River. In history, the cage culture was spread from Kampuchea to Thailand in the 1930s. Then it spread to Indonesia in the 40s . And then it spread to southern Vietnam.  The main species for cage culture in Kampuchea were silver carp, snakehead fish, beard catfish and cyprinid fish. The main specy for cage culture in Indonesia was carp. Nile tilapia and shade fish were mainly cultured in the Philippines. cage farming development The history of cage farming in Japan was also very long. In 1928, Japanese fish farmers used small cages to culture carp. After 1930, the fishermen used the cage to raise crucian carp. They sold at high prices. During the Second World War, the political situation in Japan was in chaos. The aquaculture industry was in chaos as well. By 50s, the Japanese industry began to boost. The economy began to recover. The demands for the high aquatic products were increased. But the water pollution was aggravated by the time. With synthetic fibre coming out, Japanese began to use it in the early 50s. In 1951, the fishes were cultivated in many places. After 1964, the fish culture was developed rapidly. The floating cage was popular. The fish production organization was established. In the freshwater, carp was the most popular specy for cage farming. In the sea, fish and snapper were the main species in the cages. The development of cage culture in Japan can be roughly divided into 3 stages. The 1930s was the temporary maintenance stage. The 50s was the test stage and 60s was the promotion stage. The 70s was the fast-development stage. They designed a lift cage system. With the system, it can automatically adjust the wind and waves. It could withstand the typhoon. It opened a new way for sea cage farming. The cage culture was very popular in Japan by the time. Soon the cultivation system became standardized and systematized. The hardware and processes was fully developed, from egg laying, seedling cultivation to food cultivation in the sea. The systems does not only saves land and human labour, but also reduces the cost. Inspired by the great success, the promotion for cage culture became faster by the time. In the 50s, the American countries began to miniaturize the cage. The size of the cage was even smaller. The small metal cage was with 1 meters long, wide and high. In The United States, people mainly cultured rainbow trout and catfish. The yield was even higher. In 1948, the Soviet Union began to study fish cage farming. They began to test carp cultivation in warm water in 1963. In 1968, the experiment was expanded. The test points were built respectively in 9 different places. The first fish farm of the USSR was built in 1969. The whole Soviet marine fishery began to boost. The main species were carp, rainbow trout and catfish. In recent years, European countries have put great importance to sea cage culture. The fastest growing country is Norway. More than 20 years ago, Norway sea cage culture was almost blank. The output was only 10,000 tons in 1982. In 1996, it rapid increased to 292,000 tons. The main species is the Atlantic salmon. Nowadays, Norway has established a complete industry of the fish farming. Without doubt, it has became very advanced. It includes cage engineering, automatic bait system, vaccine production and injection and fish counter. Its large cage materials are light and cost effective. It can resist 7~10 meters high wave.
