Look at the sales options and market.
Taxidermy - out as you have the market cornered

Sale as food - out as many states don't allow the sale of sportfish as food - need to be real careful here.
Sale to State or Feds for stocking - limited to nil
Sale to aquarium mkt - very limited and takes good connections
Sale to pond owners - possible but you are competing with hatcheries and the costs (have to look at all costs not just feed) to get them that size is most times more than the vast majority of pond owners will pay.
In addition you have to be trained/able to run an aquaculture operation and be willing to put in the work - not many will do that and the pay vs. the risk is low.
That doesn�t even address all the other problems like transport , permits , insurance , all those business matters. Plus if all of the sudden you show up as a newbie with 10,000 2-3 lb LMB for sale and no place to sell them (no advanced market) you will either 1. likely be eating a lot of LMB so to say or 2. selling them to someone who can take advantage of your situation for a low ball price .
