We work with a tannery in Canada that tans salmon skins. We only sell full skins. The skins measure 19 - 23" (48 - 58 cm) long and 3 - 5" (8 - 12 cm) wide. These skins are "with scale". There is no tail or head.
Salmon are not an endangered species. The skins are a by-product of the fishing industry. The salmon have not been killed just for the skin.
