Aborigine fish trap in Australia
With Yum and Dong now friends and helping each other with their children, Dum and Grunt also went out hunting together.
The women decided that they would collect fruit and shellfish and Dum and Grunt would catch animals and birds and even fish if they could work how to snare them.
As they wandered on the beach the men found the freshwater streams from the hills entering the sea would slow up as the sea pushed them back upstream again.
Dum suddenly had an idea to make a pond where the stream entered the sea and this might leave any fish in the shallows stranded in the pond when the tide went out.
They built a rock and pebble wall that would be under the sea at high tide but would retain the fresh water when the tide went out until it flowed over the wall.
They were amazed to find so many fish and other creatures trying to escape when the tide went out and they went home that night grinning at their women with a haul of fish knowing they would get more than a good feed that night.
