House Fisher of the Misty Isle was a noble house from the Misty Isle in the riverlands. According to semi-canon sources they blazoned their arms with a crowned catfish, spotted grey, on blue. It is unknown if they had any connection with House Fisher of the Stony Shore.
Some chronicles state the Fishers were the oldest dynasty of First Men river kings or the second dynasty, while the Annals of the Rivers from Peasedale suggest they were the third dynasty. The Fishers were possibly destroyed in wars with the Storm Kings or the ironmen. House Mudd ruled the Trident at some point after the Fishers.
After the Storm King Arlan III Durrandon conquered the riverlands, various pretenders unsuccessfully claimed to be river kings. One such was Ser Lymond Fisher, Knight of Oldstones, although his lineage with the ancient Fishers is unconfirmed.
