Reflection: Real World Applications When Will Our Salmon Hatch? - Section 3: Closing


In planning a salmon release field trip, there are several items to consider. The first is finding an appropriate release site. The site must have water quality that will support salmon life. My students test the water quality at a local stream monthly. We use the data gathered from these water monitoring field trips to determine whether our local stream site is a good place to release salmon. It is important to check the water temperature, pH, and dissolved oxygen of the stream. A guide for water quality parameters can be found here. It is also important to examine the release site to ensure that there is adequate space for all students and a safe path to the stream bed. 

Second, many local communities require that teachers obtain a permit before releasing salmon. It is a good idea to check with the local office of the Department of Fish and Wildlife before releasing aquatic animals into any stream ecosystem.

Safely transporting salmon fry from the tank to the stream site can be difficult. It is important to catch the salmon fry close to the time of your trip. The less time the salmon spend in transport, the better. The salmon should be transported in a secure container with water from their tank. 

Finally, setting expectations for student behavior at the release site is key to a successful field trip. Students will be handling live salmon and will be near moving water. Before the day of the trip, I review safety rules and specimen handling rules with my students to make expectations clear.
