| 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 400 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. |

| Tues | 10/23 | 39°F | 7 | 437 | - | 200 rainbow trout eggs were delivered today. We got to adopt another 200 eggs so we have a total of 400 eggs now. Some of the eggs are in the green egg stage. The eggs came from Oak Springs Hatchery. One egg has a white spot on it. |  |

| Tues | 11/13 | 50°F | 18 | 759 | 6 F | The fry are all clumped together in one corner. There are several deformed fish. The water is getting cloudy. We think it is because of the eggs shells. 381 are still alive. The fish are now swimming "upright" instead of lying on their side. The tail fins are starting to develop. |

|
| Tues | 11/27 | 44°F | 12 | 977 | 10 F | RELEASE DAY! It was 38°F when we released the fish. There was ice on Fireman's Pond. About 10 fish (fry) died during the release so that makes 370 that survived out of 400. That is a 92.5% survival rate. We think that's really good! |

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.
