ICA China is working with two Chinese companies on a massive ‘copper weir’ for a commercial fishing farm.

Dachendao Aquaculture Company began building a new copper weir project in Zhejiang province in March using 30 tons of copper netting they purchased from Wieland.

The weir measures about 360 meters in length and 65 meters in width and connects with two or more islands on a series of steel pillars to create a huge pond.

Mr. Yucun, President of Dachendao, said this weir should be the most advanced and largest weir in the world.

“We planned to introduce more than 700,000 larger yellow croakers in it this year. If everything goes well, we have the plan to build another 2 in the future. Mr. Yu added.

The first pillar was installed on March 15 and more than 125 pillars have now been installed. Dachendao Aquaculture Company plans to make and assemble the copper mesh net in May and June.

ICA China has been working with Dachendao to transfer global copper aquaculture knowledge as the project has developed.
