Answer 1

Answer:

Traditional Serie nets

Explanation:

Historically, especially by stone age tribes, fishing nets have been employed extensively. The Antrea net, along with other fishing gear, was discovered in the Karelian village of Antrea, Finland, in 1913. It is the oldest fishing net currently in use. The willow-based net, which dates to 8300 BC, was created. The world's oldest fishing tools have just been found in Korea; they date back to 27,000 BC and are known as fishing net sinkers. Sinkers and the remains of a different fishing net were discovered at the bottom of a previous sea, dating back to the late Mesolithic.  At Alta, some of the earliest rock carvings date back to 4200–500 BC. They contain enigmatic motifs and elaborate patterns of horizontal and vertical lines, which are often interpreted as fishing nets.

Answer 2

Answer:

A. Traditional Serie nets

Explanation:

A gillnet catches fish that swim into it. It has a floatline along the top and a leadline along the bottom. The netting hangs straight up-and-down in the water like a good fence .A gillnet catches fish by their gills. It works like this: the twine of the netting is very thin, and either the fish does not see the net or the net is set so that it traps the fish. The meshes of the net hang wide open. When the fish swims up to the net it sticks its head right into one of the meshes.If the fish is too small for the mesh it will swim right through and get away. If the fish is too big for the mesh it might tear the net and get away. If the fish is the right size it pushes its head and body tightly into the mesh, but it is too big to fit through. When the fish tries to pull its head out of the mesh the thin twine cuts into its skin; its gills and fins get caught in the mesh. The fish stays in the net until you pull it up Fish are also caught when the net wraps around them.Gillnets can be used in many ways. They can be made to rest on the bottom to hang between the bottom and the surface or to float on the surface Gillnets can be set in one place with anchors , or allowed to drift with the current
