The way I studied for this quiz was through going over the notes that I’ve been taking through the class so far. Going back over what I did not understand and looking at a different perspective to help me understand and retain what was said. For the one I simply could not comprehend on my own, I went back and watch the lesson to see what Peter was talking about and how he tried to explain it. Bouncing back and forth with the notes, if I really could not understand it then I would do some research on the subject and see what other people have said.

Do not think that I’ve been taking very good notes, trying to make it make sense to me is quite challenging when I do not have a firm understanding of it. I would probably need to take more detailed notes so I would be able to reference off of what was said that day .and make it to where it is easier for me to read it. What ever part that I have a hard time one, once should have utilize all of my resources to help me understand a bit more. Asking more questions to make sure that what I am thinking is correct and not just somewhat correct. Putting a little more time into studying the material because I believed that I could of done better on the first quiz.

Salmo domesticus is farm of domesticated salmon that we wild salmon generations before. Originally Salmo domesticus was an experiement created by Gjedrem and his thesis advisor Harald Skjervold, to help the declining population of Atlantic salmon. They modeled their fish farm from two Norwegian brothers named Sivert and Ove Grontvedt. The to brothers experimented with salmon by catching juveniles and raising them in nets suspended in clear water. Since salmon are adaptable fish with their eggs being large, juvenile salmon would feed off their oily yolk after hatching. By keeping large predators away, feeding the salmon herring after they would grow in size, and trial an error the Grontvedt brothers would finally have a steady growth of salmon. Since Gjedrem and Harald were modeling their salmon farm after the Grontvedt brothers, they would choose different fish with particular traits to keep and raise. With still a vast amounts of wild salmon, Gjedrem and Harald would pull salmon from 40 different streams and raise them with the understanding that salmon would grow faster. With the cross breeding after generations and generations of salmon, the growth rate of those farmed salmon doubled. The end result there are now millions of those fish around the globe. Though domestication and cross breeding of salmon is beneficial to keep the salmon species to live, I believe that it has adverse reactions. We created Salmo domesticus to keep the salmon species from dying out, but since cross breeding salmon and the demand for salmon is high the identity of true wild salmon themselves are dying out. Since “wild” salmon are fish that lay millions of eggs with maybe half of them hatching, raising them would make the true meaning of “wild” obsolete.

What I believe what Paul meant when he said, “I couldn’t help but think that in a way the future of wild salmon and the future of the Yupik people were somehow sadly parallel to each other.”, was that the way of life of the Yupik people was dependent on salmon. With each coming year the return of salmon has been on a decline. Since the “norm” continues to change so does the demand. The increase in salmon demand has drastically lowered prices. Paul stated that he saw what easily could of been an expensive 30 pound fish bartered for 2 ten pound packages of frozen chicken parts appraised at 20 dollars. With the slowly disappearing of salmon in rivers and demands increasing, Greenburg believes if this continues the Yupik would have to relocate and survive on something else.

I would have to agree with Greenburg on some views. With facts that he would have presented during that time it shows a steady decline. With a town that solely depends on fish caught, the townsfolk would have to relocate if the salmon numbers were scarce. How the world trying to preserve and increase the number of salmon the Yupik’s way of life does not have to disappear. Biologists have tried crossbred salmon to increase rate of survival after being reintroduced into the wild. Slowly but surely bringing back salmon to their former glory through trial and error. Reintegrating them in streams where they once were and even having different species that are not native to a specific regions to help the population thrive.
