Salmon Nets :: Shared Description
Salmon hatch and spend the first year or two of their lives in rivers, before migrating to the sea where they grow to maturity before returning to breed. They swim parallel to the shore until they smell their native river, and then swim upriver to spawn in the very place where they were born.
Net fishermen exploit this behaviour by erecting nets on beaches. The net is in the shape of a long arrow pointing out to sea. Fish encounter the leader, that is, the shaft of the arrow, and turn to seaward. At the end of the leader, they are guided by the V-shaped end of the net into a bag at the apex of the arrow, from which they cannot escape. At low tide, the fisherman comes along and collects the trapped salmon from the bag.
A variant is a double-ended net, where instead of an arrow to seaward, the leader feeds into two bags at right angles to the leader. This type of net tends to be used on rocky shores and in deeper water, and the catch is collected in a coble.
Most beach nets are no longer in use, partly because salmon numbers have fallen and it is not always economically viable, and partly because conservationists or the angling interests on the rivers buy out the netting rights and close the netting down so that fish actually reach the rivers in greater numbers.

These Shared Descriptions
are common to multiple images. For example, you can create a generic description for an object shown in a photo, and reuse the description on all photos of the object. All descriptions are public and shared between contributors, i.e. you can reuse a description created by others, just as they can use yours.
