Piškera

Piškera (also called Jadra ) is a small uninhabited Croatian island in the Adriatic Sea. It is one of the Kornati Islands in central Dalmatia and its area is 2.66 km2. Its coastline is 10.64 km long.

A fishing settlement of the same name, established on the island in the 16th century, was gradually abandoned after the demise of the Republic of Venice in the late 18th century. The island's name is derived from peschiera, Italian for "fish farm".

A marina with 118 berths operated by ACI Club, located off the coast of an adjacent isle of Panitula Vela, is open between April and October every year.
