Fish Trap

Fish traps are traps used to catch fish. Fish traps can resemble a variety of shapes, from large ones such as fish-catching weirs to small ones such as lobster traps. When fish or other marine animals enter the trap, they can not get out again.

Fish traps are found in different cultures in the world and are growing independently. There are two types of traps, which are either permanent or semi-permanent, and that can be moved at any time.

The Mediterranean Sea is an area of ​​approximately 2.5 million km2. The shape resembles a bottle neck where fish entering from the Atlantic Ocean through the Strait of Gibraltar will find it difficult to find a way out. The Mediterranean Sea is called the biggest fish trap in the world.

The Yaghan people who inhabit Tierra Del Fuego build a rocky construction in the narrow gap of the shallow river that keeps the fish trapped inside when the water recedes. Some of these constructions are still on the archaeological site of Bahia Wulaia.

In the south of Italy around the 17th century, a new fishing method developed. Trabucco is a large trap fishing machine, built of wood, and scattered on the southern coast of the Adriatic, especially in the province of Foggia and part of the coast of the Sea of ​​Tirenia. One of these machines is preserved as a monument on the coast of Gargano.

Indigenous communities of Australia before the European colonization, inhabiting the waters edge of the Murray-Darling basin and the river that flows from it. The water levels in the area fluctuate over the course of the seasons, and they build stone traps made of stone. Most of these structures have been damaged. One of the most awake structures of Australian native traps is located on the Barwon River in Brewarrina, New South Wales. Fish traps Brewarrina still traps migratory fish throughout the year by itself along with the ups and downs of river water levels.

In the southern part of Victoria, indigenous peoples developed a canal system of up to 2 km to attract the eel and capture it. At the end of the canal was built a construction made of stone to trap eels. The traps are built on site and different altitudes match the tide height. This construction is more or less the same as that found in northeastern California built by Native Americans.

A method called fishing with a dam was developed by the Baka pygmies. Construction of non-permanent dam in the upstream causes a decrease in the water level downstream of the river so that fish are more easily captured.
