The fishing boats arrive every weekday between 6:30AM and 7AM and quickly unload their catch. Forklifts transfer the fish to a building where and auctioneer takes about 20 bidders from pallet to pallet. Once the pallet is won, it is quickly moved again to trucks outside.
Open to the public but stay out of the way of the forklifts.
We had some difficulty finding the entrance but this map will help.
