Fishing plays a role in the island's economy, but similar to other Aegean islands, agriculture is a more significant economic activity. The local fishing industry is small, with the port authority counting 48 boats and 120 fishermen in 2011. Local fishing is year-round and seafood can be obtained in all seasons. The fish population has gone down over the years, resulting in a shrinking fishing industry, though increase in tourism and consequent demand for more seafood has benefited the industry. The sea off the island is one of the major routes by which fish in the Aegen sea migrate seasonally. During the migration period, boats from the outside come to the island for fishing.
