Pond Boss Forums MANAGING AN EXISTING POND Corrective stocking I Have a Plan… Almost

To my knowledge, I've only seen the Pumpkinseeds spawn once a year, towards the end of May or beginning of June.

My answers to your questions.
1) The smaller the fish, the shallower the water. Typically they stick to 4' deep or less. during most of the summer.
2) Or Optimal Food and have it shipped to you. You most likely won't go through more than 2-3 bags this year, it's all up to you. You can feed as little or as much as you like per day, as long as they eat all you give them within 15 minutes of throwing it in the pond.
3) You can aerate. You need roughly 1/10th of the surface area open. Do it in the long narrow finger and string up barrier tape from shoreline to shoreline. After the first year you will see how close you can set the barrier tapes. 1/4 hp compressor, 1 diffuser will be enough. Or go with two, one in the deepest water that you shut off for the winter.
4) Dense cover near the spawning beds. Openings that are small enough to discourage the LMB from going into the cover after them. You want 20%-25% of the pond in cover, in all areas of the pond, deep water to shallow water. They will utilize the deep water,
