You can get some good information on how to maximize BG production with this TWPD pdf that covers the production of BG fingerlings. Below is an excerpt from this document.

Quote:
With a broodfish stocking rate of 100 pairs/ha (40 pairs/acre) and assuming a 50% hatch rate, approximately 774,074 advanced fry/ha (313,500/acre) can be produced from a well-managed pond. However, Huner and Dupree (1984) reported that under normal circumstances about 300,000 fingerlings/ha (120,000 fingerlings/acre) are produced.


This is certainly more fingerlings than a few dozen 2" LMB need in their first season. Imagine slipping some LMB fingerlings into a hatchery pond when they are just stocked with BG broodfish. I dare say there will be lots for these tiny LMB to eat. I don't think the growth could be much greater except for cases where FHM are allowed to build for a year.

The adult BG are like a grass that can seed multiple times all summer where its scattered seed germinates in only 3 days and forms a seedling. If there were a creature that could eat seedlings then it could flourish and thin the seedlings so that they could grow. That creature would need be small and much fewer in number than the seedlings. But if that creature met that condition the field of seedlings would be like a lush meadow.

We would use much more adult BG than we do except for the space requirements. It not economical (or even practical) for a fishery supplier to meet all of the demand for BG with adult fish. The BOW owner must settle with what is available even if it isn't optimal or encourages one to delay stocking LMB.
