| Our class is lucky to be part of the Kokanee Karnival program, sponsored by the Central Oregon Flyfishers, Sunriver Anglers, Oregon Department of Fish and Wildlife, and many other sponsors. Part of our studies include raising fish in the classroom. We are raising 200 rainbow trout for eventual release into our local Fireman's Pond. Each day we check the water temperature and weekly we check the water's pH. We remove the dead eggs and fry needed. Below is a summary of our fish incubation project. See our projects from the past. |

Question: What is a "Temperature Unit"? One Temperature Unit (or T.U. as we refer to it) is one degree on the Farenheit temperature scale. The eggs earn one T.U. for every degree above freezing (32F) our water is. For example, if the water is 40 degrees, that is 8 degrees above freezing, so the eggs have accumulated 8 T.U.s or 40 - 32 = 8.
