What do Brook Trout Need?
1. Cool Water: In all living things, many chemical reactions occur all the time. The constant break down of food provides the building blocks for important structures we need to live, such as the heart and brain. These processes can only take place within a specific temperature range. Oxygen is also important to these processes, and it dissolves better in cooler water. Brook trout need water that stays below 20C. How can we help? Plant trees for shade along the shore of the creek. Protect groundwater sources. 2. Oxygen: All living things need oxygen. Fish use oxygen that has dissolved in the water. The movement of a stream, called turbulence, helps mix oxygen from the air with the water. There may not be enough oxygen in a stream because of too much organic matter and nutrients. Orqanic matter was once part of a living plant or animal, such as food, leaves, feces, etc. Fallen leaves and other plant matter provide valuable food for insects and other creatures, but too much organic matte
