A famous fish market was opened in Šilutė almost 500 years ago, when Georg Tallat purchased the inn together with the land and fishing rights in 1511. The town was a gathering place for peasants from nearby Samogitia and Curonian and Prussian fishermen from Rusnė, Karklė, Nida, and Lesnoye.
The coat of arms, which reflects that, was designed in 1968. It depicts a white sailing ship. On top there is a traditional weathercock (Lithuanian: vėtrungė) used by local fishermen. At the bottom there is a horn, an old symbol of postal services. These symbols hint to the Curonian Lagoon, traditional fishing business, and Šilutė as the old sea port. For a while Šilutė was along an important postal route.
