Michael:
Welcome to the forum.
If you are referring to the auctions at our monthly meetings, we typically have somewhere between 75 and 100 lots in the auction, depending on lots of factors. Often, the auctions have fish from club members who are part of our Breeder Award Program and have spawned fish and are getting bonus points for auctioning them. The auctions also usually have donations from our members and sponsors, and on occasion our speaker will bring fish to be auctioned. All in all, they typically have some great fish at great values.
We also hold a marketplace "swap meet" at our annual event, The Big Fish Deal (March 4th thru 6th this year). There are around 40 vendor tables with a large assortment of fish. It's a great time.
