Although no one would ever dare fish this way these days, there was a time when catching Yellow Belly Perch was a boring and fly pestered occupation.
Occasionally the fish would rise to the bobby cork, but line fishing would most often bring turtle after turtle and that 's about all.
So, the equipment needed to assure yourself of a feed of Golden Perch from the muddy brown water holes along the water courses was: Take one empty golden Syrup tin, some news paper, a bit of scrap metal and some carbide. Carbide was use for the carbide lamps, and came in rock formation in sealed five-gallon containers. Some folk use carbide to ripen bananas as well.
The method: Place metal scraps in the bottom of the tin, which has had a small hole pierced in the bottom as well as the lid. Put 'some' carbide rock in the tin,pack down with shredded news paper, not too tight, but sufficient for water to leak in the small hole and through the paper to the carbide. Then solder the lid on solidly.
Take a few tinnies of barb wire, and a bag to put all the fish in, and then, "Cast the lure" or toss the bomb into the river. It may take a tinnie before the bubbles start and then shortly after the "Kaboom" and the water lifts and settles, then the fish float on their sides, but only stunned.
Stopping the dog from swimming out for a free feed, you wade out and get hold of as many of the bigs ones that you need for a dinner or two, and head home after consuming the rest of the tinnies. The other fish floating around will soon come alive and go back to what ever they were doing.
You will have the fish in the bag, which you have soaked in the water while you had a drink, so the Yellow Belly will survive until you get it back to the main station.
In dry times, Yellow Belly go into the mud, and a torpor, and may survive in this pocket of mud for considerable time, or until the next rains.
Take the fish home and release into a previously half filled water tank of fresh water. It can be muddy water that has settled, but not bore water as it is too harsh for the fish and they will taste funny.
The fish will exude the mud from their guts in the fresh water environment, and will serve up a lot better than straight from the river.
Make sure you cover the tank with wire netting or you will only provide a free diner for the pelicans, storks and kingfishers, like the Kookaburra, which is Australia's largest Kingfisher.
