The Gros Morne National Park in Canada said it replaced the 86 drainage holes with a fish-friendly environment that allowed fish to move more easily.
This fish-friendly drainage project is part of an ongoing major road infrastructure improvement project in the National Park, with drainage in the area of approximately $ 45 million.
According to ecologist Tom Knight, the water flowing through the old drainage does not run fast, and the bottom is easy without the rocks where the fish can rest. The old drain pipe is built higher than the edge of the river, making it difficult for fish to swim easily.
Knight says, "Fish is not different from us. When a person runs on a treadmill, the fish run quickly and then the energy is discharged and eventually they can no longer run the treadmill. Fish is the same. "
Old drainage is convenient without rocks or places where fish can rest. The old drainage channel is much higher than the edge of the river, making it very difficult for fish to escape.
The new drainage line allows the fish to go out brightly and into larger rivers and waterways. It is also as high as the edge of the river.
Knight plans to track whether fish such as salmon, trout, and eel will move more smoothly through the new drainage port and replicate more after the drainage is replaced.
