The Salmon Tank project literally puts the health of salmon into the hands of students and their teachers who are responsible for maintaining adequate living conditions in their classroom tank. Students monitor the temperature daily and watch as eggs hatch and their fry start to feed. By monitoring water quality, being responsible for cleaning the tank, and feeding the salmon, students learn what salmon need to thrive.

We have watched as our youth learn and make a connection to their salmon, this translates to a connection and sense of responsibility for salmon living outside the tank. We hope this in-school experience during students’ formative years will help establish a strong stewardship ethic that extends to all aspects of their lives moving forward, and that they will play an active role in keeping the Copper River watershed intact and functioning for salmon and people into the future.

Migrating fry from Mentasta Lake, near the headwaters of the Copper River, travel almost 300 miles down to the Gulf of Alaska, where they grow into adults and eventually return to Mentasta Lake and its tributaries to spawn and continue the life cycle in the very waters where their journey began. Salmon are able to complete this complex life cycle because the Copper River watershed is mostly intact and has clean, clear waterways interconnected and winding from inland, freshwater streams and lakes all the way down to the ocean.

Similarly, because there are strong ties between 11 partners throughout the watershed, from Mentasta Lake to Cordova at the mouth of the Copper River, we were able to support six salmon tanks at all schools in the Copper River watershed, allowing all students in the region to witness the amazing and delicate early life stages of salmon, while taking an active role in caring for the resource that sustains their cultures, communities and their way of life.

March: Yolk sacs get smaller as alevin absorb nutrients from them.

This process is referred to as “zipping up”.

April:  Free swimming fry!

The insulation is removed from the tank and the students teach them how to eat.
