A 150,000-tonne deep-sea intelligent aquaculture vessel was delivered for use in Qingdao. The ship is 244.9 meters long and houses 15 breeding cabins with a total water holding capacity of nearly 100,000 cubic meters.

The ship-borne smart aquaculture system is expected to have an annual output of 3,600 tonnes of high-quality fish. The breeding cabins can be used to cultivate fish species such as large yellow croaker and salmon.

The new aquaculture vessel is an updated version of its 100,000-tonne predecessor delivered in 2022. Its predecessor has now already traveled over 17,000 nautical miles. The vessel pushed the aquaculture area from nearshore to deep sea, using high-quality seawater resources for breeding.

During the Chinese New Year holiday, a mountain climbing support robot jointly developed by Taishan Wenlun Group and Shenzhen Kenqi Technology Co. was test-introduced in the Taishan Scenic Area. Guangming reported.

According to Taishan Wenlun Group, the mountain climbing support robot can be used in a wide range of areas in daily life and work, such as mountain climbing, fitness, running, walking, and climbing up and down stairs. It weighs just 1.8 kilograms and is ergonomically designed with power, electronics and artificial intelligence (AI) algorithms. It can sense every movement of the lower limbs and provide support at the right time.

According to the group, it can operate continuously for more than five hours.  The product is currently in the trial operation phase, and the company plans to launch 200 units on the market in early March.

In a large-scale deep sea smart fishery farming facility “Deep Blue 2” in the Qingdao National Deep Sea and Ocean Green Aquaculture Test Area, approximately 400,000 salmon are farmed in farming cages, with a high survival rate and healthy growth.

According to Gu Qihuan, production manager at Shandong Caijing Wanzefeng Marine Technology Co., Ltd., salmon farming requires strict environmental conditions, and it is very difficult to find suitable sea areas for large-scale farming. However, this location is home to 130,000 square kilometers of Yellow Sea cold water mass, and the water temperature in summer is 10 to 16 degrees Celsius, which is very suitable for salmon growth. Deep Blue 2 sinks to the level of the cold water mass less than 30 meters in summer and rises to the surface again in winter.

Deep Blue 2 is 71.5 meters high, 70 meters in diameter, and has a fully submerged farming area of ​​90,000 cubic meters. It is equipped with multiple smart farming equipment such as an automatic feeding system and an underwater photography system, making unmanned farming in the deep sea and distant ocean possible.

For harvest, schools of salmon are sucked up one after another onto work boats, passed through a fish-water separator, and transported to a workshop for processing. Workers place the salmon in insulated boxes filled with ice and transport them to land overnight for processing and sale.

The freshly caught salmon weigh an average of 3-4 kilograms each, and each harvest is about 5,000 fish. At the earliest, they can be delivered to major cities in China in just over 30 hours.
