KEEP FISH NET / Fish pond net

The countries and regions that near Earth's equator are one of the best places to fish ponds,but their annual rainfall is high.When the heavy rainfall,the fish escape with the high water level.That makes a millions of economic losses which can destroy a large number of fishers' families.
KEEP FISH NET was made up of the Floating Tubes and a Net.The Floating Tubes will always float on the water by buoyancy. So that the Net will surround a space in the water over the fish pond and keep the fish in this space.
And we design a hook to link the Net and Membrane because it is the most sturdy and universal way to set the Net.
