What is the fish ladder?
Fish ladder is a structure that allows fish to move around an obstacle like a dam. Without fish ladders, the fish would be stuck downstream of the obstacle, and this could have a potentially negative impact on breeding cycles and fish lifestyle. Many dams are equipped with fish ladders, often to meet the requirements of government agencies and some dams have changed their fish ladders in the area of wildlife viewing, allowing visitors to watch fish as they move on the ladder. Fish ladders are actually produced by creating a number of degrees. Fish can jump from the pool to the pool, and finally come out on the other side of the dam or obstacles. There are a number of different designs and configurations for pools. For especially large dams, people can use a fish elevator instead. Like the elevator of people, Rybavyh is filled with passengers and then rises to the top of the dam before opening to allow the fish on the other side.
inDependents on where one is one can be referred to as fish ladders, fish passes or fish steps. They are usually designed so that the water is noisy, which attracts the attention of fish that can fight at the foot of the dam. The water is kept calm enough so that the fish can swim in the pools, because fish ladder ladders do not want the fish to get tired so that they cannot successfully navigate the fish ranking.
In some cases, the fish ladder may be mounted in the glass chamber on the side of the dam, allowing observers to monitor fish as they move on the ladder. This can be useful for biologists who want to study the movement of fish populations and look at how dams affect fish in a particular region. Visitors can also enjoy watching fish by jumping from the pool to the pool, or jumping on the fish ladder, depending on the season and the species.
Local wildlife may also be interested in fish ladders because the ladder limits fish in a narrow entry, which makes it easieris to insert and grab refreshments. Bears, eagles, raccoon and other fish eaters tend to gather around ladders of fish, considered to be moving feasts of fish species.
people have recognized the impact of dams on fish since at least the 16th century, when fish ladders began to build for the first time. The modern version differs little from ladders of the 18th and 19th century fish, illustrating the reliability of the basic fish ladder design.
