Today our students made observations about the structures and functions of the external features of rainbow trout. This is part of a larger unit on ecosystems, which has included students analyzing cause and effect relationships within food webs. Later this week we will receive rainbow trout eggs that will be raised in a classroom incubator, and our focus will shift to the role of trout in an ecosystem. Stay tuned for more on this project. Thank you, Mr. Koepke for donating the trout for our students to study!
Our rainbow trout are enjoying their second day in their new habitat. We have been fortunate for many years to have access to release our trout in a private pond on the property of Armenta Cellars winery in rural Newberg. This year’s release was a great success. The weather was amazing, the kids were well behaved, and our trout were very healthy. In fact, the survival rate for our trout from the egg stage to fry stage was 99.8%, which was our most successful project since we started in 1993. We’re already looking forward to raising salmon in the fall!
This is a first for us – an underwater view of our trout, which are now entering the fry stage. They are coming along quite well and their release to a private pond is in sight now (date TBA). Thanks to Jeff and Adam for the use of their GoPro camera!
Our students did a great job today during our trout observation and dissection today. A big thanks to DoLoresKoepke, Bill Koepke, and Dense Mapes for making the necessary arrangements and connelab ctions with the Pacfic Northwest Sportsmans Show in Portland this past weekend so that our students would have this opportunity.
Here’s an aerial view of our trout, which are now in the alevin stage. The hatched trout now have an egg sac attached to their undersides. It is their source of nourishment for the next few weeks until they are ready to be released.
On Monday, February 9th our 4th and 5th grade students will be participating in our biannual observation and dissection of rainbow trout as part of our Trout/River Ecosystem Unit. Since this activity will be a bit messy, we are requesting that all students wear appropriate clothing. If you would prefer to not have your child take part in this activity, we will assign an alternate related activity that will count for full credit. If you have any questions, please don’t hesitate to contact us. Thank you.
Our rainbow trout are beginning to hatch today! If you look closely, you will see the tail fins (caudal fins) emerging out of some of the egg sacs. More pics and video forthcoming in the upcoming days!
Our trout eggs have arrived for our classroom trout hatching program. Thanks to Mrs. Reed’s husband, Mr. Reed, for driving to the Clackamas ODFW office to pick them up. We will begin to observe their daily development, collect and record data, and learn about trout and their ecosystems in the coming week. In a month or so when they reach the fry stage, we will release them in a nearby private pond. Stay tuned for more “developments!”
