| 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 wter's pH. We remove the dead eggs and fry needed. Below is a summary of our fish incubation project. |

This egg has a fungus or something

These are the eggs we are watching. They have white spots on them. |
Do you notice the two eggs that are dieing?

See all the dead eggs? They are the white ones. |
This is what they look like after we took out the dead eggs. |

One last look at our tout. |
We took them in a cooler to Fireman's Pond. |
Can you see two of our survivors in the pond? |

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.
