Whitby harbour is used by commercial, fishing and pleasure craft.
Inshore fishing, particularly nowadays, is for crustaceans and line fish taken from the sea place along the nearby Yorkshire coast. Lobsters, brown and velvet crabs are amongst the seafood caught by local fishery.
From May to August, salmon is fished in the Esk and small open boats are licensed to net these off the harbour entrance. There are around 40 licensed angling party boats.
The commercial catch is no longer herring like in the 1960’s and has been replaced by whitby fish such as cod, haddock and other fish caught off the North Yorkshire Coast. The Whitby Fish Market on the quayside operates as need arises.
