Salmon Release Field Trip
 
We went up Freshwater Creek to release the salmon we'd raised this year with Ethan in the Science Lab and also to visit the fish hatchery and engage in some salmon ecology activities.
 

   


by Freshwater Stream
Ethan releases the salmon fry
everyone watched the fry swim free
looking at the salmon fry in the tank at Freshwater hatchery
this tank went unused this year
Fish & Game Department scientists told us about their salmon tagging system
and showed some of the other stream species that can show up in their fish traps, like this lamprey
boarding the bus again...
...for Freshwater Park, where we started with a run to use up some excess energy
then we wrote poems about raising salmon and illustrated them
Zack chose this quiet spot to reflect on his poem
Cody's included this particularly fetching artwork
next we had the opportunity to collect invertebrates from the stream...

Harry, one of the Humboldt Fish Action Council volunteers, helped us to identify species at streamside
...as did Ethan and the invertebrate identification keys up at the picnic benches
...aided by these magnifiers and some microscopes
watching a mayfly that had just emerged take flight for the first time after drying its wings
after lunch we played the salmon survival game which involved first "swimming" down river through the "power plant turbines"
if you survived that, you had to make it past the "eagles" in yellow vests
then make it through three years in the "open ocean" avoiding capture by the "fishing trawlers" (taggers with a box on one foot)
collecting a "year" token from an adult at either end of the ocean three times and finally
heading back up river through this "fish ladder" while hopefully surviving the "bears" above
...then you could jump the "water fall" finish line and "spawn" to "win the game
