Now nail all 3 pallets together so they are stacked one on top of the other. Next, strap a 55 gallon barrel to the top pallet so everything floats. In the Spring when the water warms to around 60 degs, then float the pallets over several feet of water and anchor to the shore with a couple ropes stretched around a couple T posts. This spawning structure will be above the level of any crawfish from accessing the rosie's eggs and cannibalizing all the eggs. The rosies will spawn at least 5 times during the warm season. I would start with a minimum of 500 adult rosies. I anticipate that your first year you should produce around 60,000 rosies and that is probably conservative. If you start with less than 500 adults then it will take longer to see good results. I stocked aprox 1,800 in a 1/4 acre pond this fall for the Spring explosion. You will not be able to successfully provide sufficient food and room for your 100 minnows to survive and breed in a 75 gallon tank.
The rosies spawn upside down on the wood so provide the maximum amount of surface area you can with the pallets. Rosies are real easy to trap with cattle cubes or other bait.
I have done this before and the nice thing is that once you get a good supply in your pond, EVERYBODY wants your minnows. Been there, done that. If you are going to do it then do it ONE time and do it right.
