4 While we were there, we tested: The variety of fish, and the size of said fish. Checking the depth of the river. Looking at the composition of the riverbed. The variety of invertebrates, by kick sampling. The speed (velocity) of the river, using oranges.

5 Investigation

6 Trout fishing This is a picture of the fishing Here’s another picture

7 Substrate Size The substrate size was far to small there was not a variation of different types of substrate. Which means there is not enough habitat for young trout to live and for trout to hide.

8 Why the substrate is so small The Substrate is so small because there is no meanders so the water flows fast taking large stone with it and leaving mostly just sand.

9 Meanders The Mouse Water is mostly straight and some points meander. Quite a while ago the Mouse Water was straightened so less meanders were there. This happened so that farmers had more useful land to grow crops. So there aren’t many meanders.

10 Depth of the river… Overlooking The Work Depth 1 = 31cm Depth 2 = 31cm Depth 3 = 31cm This proves that the river is fairly straight and that the large rocks have been dragged back because the river is straight and so it is faster making it easier to carry away rocks and leave the small stones and so on, creating sand.

11 Shape of the River we tossed oranges into the river to find the velocity.

12 The Mouse in Particular There was NOT many plants on the river banks, so the land could be easily eroded. This could, in turn, cause the land to fall in the river, making it massively dirty. There were no trees nearby, meaning the fish had no shade to cool down. There was some riverweed, which is a good sign.

13 This is what a perfect river should look like……

14 How to Solve the Problem

15 Deepen it in areas and add rocks For fish to live in … …and lay eggs.

16 Plant trees and add fences Fences can keep livestock away from the river. Vegetation along the riverbank can strengthen it. Roots and branches can provide habitat for fry.

17 Create meanders For fish to stay in and to calm the water
