The problem of depletion of natural fish sources has gradually shifted the aquaculture fishery to the focus of the global aquaculture industry. According to the Nikkei website, since 2013, the global catch of aquaculture fisheries has surpassed natural fishing. Depending on artificial cultivation, it is possible To ensure the stability of the global marine ecology and take into account the food supply, the question is how to improve the efficiency of aquaculture and fisheries.
There is a problem in agriculture that it is not easy to estimate the yield in advance, and the onshore cattle, sheep, pigs, and chickens can be weighed at any time. The fish is caught and measured and it is easy to be injured and killed. Now using the new IT technology, it is expected to break through the technical limitations and greatly improve the efficiency of aquaculture and fisheries.
For example, Japanese aquatic food companies, Nippon Suisan, and Japanese IT major NEC have cooperated to carry out real-time underwater monitoring from April 2018, take pictures of fish with underwater cameras, and automatically calculate each fish with artificial intelligence. The size and estimated weight of the fish are used to determine the status of the school of fish. Due to the success of the experiment, a number of farmers have participated since October. They are scheduled to be officially launched in April 2019.
In the past, the number and size of fish in aquaculture ponds had to be calculated. Because the fish would swim constantly, the fish would be injured when they were picked up, and a large amount of manpower must be continuously monitored to make the fishery personnel cost very high. Service, you can remotely monitor fish schools with your mobile phone, and estimate the catch, which is expected to greatly reduce the labor costs of fisheries.
New entrepreneurs also have achievements. For example , the aquaculture startup Umitron, which was established in 2016 , proposed to combine the Internet of Things (IoT) and satellite data analysis to determine the ocean temperature and nutrient status. You can decide how to deal with it before the cold wave erupts. The amount of fish feed can also be adjusted, and there are currently examples of successful reductions in fish feed costs of 10%.
After the performance of fisheries and start-ups, Nikkei reported that the Japanese big trading company also noticed business opportunities in this area, such as Mitsui Corporation (Mitsui) put into drone fisheries monitoring, and in August 201 The company cooperates with Japan Fisheries.
However, Japanese aquaculture companies say that they are not investing in IT technology farming because they want to be ahead of the world, but they have to catch up because they are behind. For example, Norway ’s world ’s largest salmon farm, Marine Harvest, has the largest revenue in Japan. Maruha Nichiro's half, but the net profit is more than twice, even though some of it is benefited by the exchange rate, but Marine Harvest is more efficient, it is an indisputable fact.
Based on the current global aquatic food consumption and catch trends, it is estimated that there will be a shortage of 30 million tons in the global catch market in 2030. If you do n’t want to go all out and improve your aquaculture capacity, it is the only way and a huge business opportunity. .
