I use these contraptions to feed and breed my fish.
the first one is a devise I made up to feed my fish.
It consist of a length of tie wire and a cork float, this system of feeding does many things it first allows me to supplement the natural food the fish find for themselves and to make sure fish are well fed it also allows me to check on the health of the fish. if fishes come up to near the surface and feeds vigorously then all is well. the wire is soft and easy to bend if a fish did get caught it can easily release itself. the cork is a leftover from my previous trade it is a natural substance its actually the bark of a tree its stuck together with latex adhesive witch is water based and cannot in any way hurt the fish.
The picture above shows a breeding box its made of ply wood and nailed together its about ninety by ninety in diameter and six hundred in length the long stick is so it can be fixed at a depth I generally keep it shallow these fish seem to prefer to nest nearer the surface usually less than a metre deep. I did use polypipe but decided to go with all natural products to try and imitate nature as closely as possible.
this is the kind of food I feed the blackfish this is a large Yabbie ( cherax destructor ) he was born and bred on this farm this one has been in a fight with another yabbie and has lost the tips of his nippers. wood grubs and moths are also used when available.
