Gilbaka, also known as “Gillbacker” is a scaleless saltwater fish that is part of the catfish family.  It is found in the muddy sea bottoms of coastal rivers from Guyana to northern Brazil.  This sea catfish can grow to enormous sizes and is quite meaty in texture.  It is by no means a “pretty” looking fish, but it is quite delicious.  It stands up well to heavy seasonings and high temperature cooking. Gilbaka has very thick, smooth skin that is light grey in color; once cooked, it becomes dark and gelatinous.  For this reason alone, very few people enjoy eating the skin.
