So for my groups oceanography project we were all interested in building stuff, this seemed like a tough one to demonstrate, with chemistry they knew what they were studying, ph of the water and such. But with building stuff, well building what? whose building? these questions lead us to some very interesting research, lots of people were building things to help out the ocean, some using rotary fishing traps to count how many fish were in rivers and release them again. One in particular that caught our eye was what they called a "Salmon Cannon". we figured this would be nothing we could base a real project off because it just sounded so ridiculous. As we read on Whooshh Industries website and watched the video on Last Week Tonight With John Oliver that explained it, we began to realize we had an idea that would work.
We knew that the "cannon" worked for salmon in the Seattle area where they started the idea to move salmon over dams there, but our question is would it work here to help them get back to creeks where they used to lay their eggs before we damed them off.
My first standard was species population, because of the creek dams and also pollution the salmon can no longer go back up the creek they were born in to lay their own eggs. There have been a significant drop in salmon fry and salmon who come back from the ocean to lay eggs successfully, the fish cannon should offer some solution to this issue.
My second standard was humans relationship with the environment around them, the whole topic of building stuff for the ocean has to do with this and by installing salmon cannons around in various water sources, maybe even utilizing them for other kinds of fish, we are involving the community in their surroundings, and who doesn't want to find out whats going down when they hear there's going to be a salmon cannon in the Napa river?
My hypothesis for this experiment is that it would prove to be a valuable resource in our river to help restore the salmon to their original numbers if we had the funding to actually install one after this prototype.
