Taxidermy has been practiced for as long as people can remember and some fisheries have their resident 'celebrity' fish stuffed when they die.
Occasionally these fish come up for sale and there is a company on eBay that specializes in selling them. The Fishermans Emporium 's eBay shop is here --> http://ebay.to/2rlLIga
The shop has everything from perch, carp and tench, there is even a zander listed. These make fantastic talking pieces in shops, man caves, bars or even in your living room.
