FTT #4

For our first quiz, I basically just went through the notes that I took during class on the slides and reviewed it. If I was unsure about a topic or couldn’t remember what we talked about specifically I tried to find the recording of that lecture so I could fill that section in. If I didn’t understand after watching the recordings I would’ve contacted Peter with questions about it. When he would emphasize a topic or slide during the lecture I would put a note saying that this might be on a future quiz so I should probably pay extra attention to it and/or review it after class to make sure I understood the concept. Sometimes it takes me a few minutes to actually understand the graphs so I spent a good amount of time making sure I really knew what was happening and interpret them correctly. I hadn’t seen the Lord of the Rings movies in a while so I’ll be studying those this weekend just to refresh. 

It really helps me to “teach” or just have a conversation about it with someone else. I don’t have anyone who really knows about this stuff to talk to but my dad will listen to me. He usually will have random knowledge about it from a podcast he listened to. When I can’t talk to him I’ll talk to my little sister, she’s 8 so she really doesn’t know but she likes learning about what we do in class and it benefits me.

I think my studying worked for me and I’ll definitely do these again but I will also rewrite the important things down to help memorize them for the midterm. To have the definitions and graphs and everything else separate from all the slides would be easier to study with than going through the slides all the time.

Salmo domesticus was created in Norway in the hopes to achieve the selective breeding that the U.S. had begun to discover. Salmon eggs are considerably larger than most other fish eggs and when the fish are growing inside the egg they simply feed on the egg for the first few weeks of life. Other species of fish are not able to do this and require a safe space to live and small enough food to find. It was found that if the young salmon were able to be protected and given sufficient food their survivability would increase. Which would lead to Gjedrem and Skjervold narrowing down the specific salmon they wanted to breed and create a new generation of farmed salmon from their wild parents.   

I think that it’s great they are able to provide salmon to places that had never had salmon and struggle with having enough food for everyone but as Greenberg mentions in the book, roughly a million farmed salmon make it into the wild every year. Those farmed salmon can cause huge problems for the wild salmon population in that area. I would think there is more damage that could come from the farmed salmon population than positive changes in the wild ecosystems. Somethings that come to mind are: If there were no farmed salmon population would there be an increase in commercial salmon fisheries to fill that void? How much of a hit would the wild salmon population take to make up for the loss of the farmed salmon?

I think what Greenberg means by “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.” is that without the Yupik people fighting to save the salmon and protecting the salmon and their own rights corporate greed could take over. They could take advantage of our natural resources and a big part of a lot of Alaska native cultures as well as the main food source in the summer that often flows well into the winter. I think I agree with him. Without the support and need for salmon in Alaska (by Alaska natives and Alaska residents) both the Yupik people including their land and future generations of salmon would soon dwindle. If I remember correctly that would be a mutual relationship between salmon and the Yupik community as they both benefit from each other. In a way, I think if there was a huge loss of salmon population across the state there would be a large push for hatcheries to stock the rivers and lakes and more rules and regs to limit fishing until the numbers were increasing. 

Something I hadn’t thought about was the “wild-stocked” salmon here in Alaska. Normally about 80% of naturally (no human interference) laid eggs die due to natural selection. It’s brought up that when the smolt from hatcheries are put into their respective rivers based on their parent’s genetics and so on could be bringing in the weaker bunch of salmon or the ones that would have died if they had been laid in the wild. Bringing them into the rivers could cause “bad” genes to be passed onto future generations which could ultimately lead to weaker and smaller populations of salmon in that area.

Paul Greenberg begins his book by setting the scene, 1978, in Greenwich, Connecticut. He describes the winter of ‘78 as having “a fierce blizzard, temperatures were often below zero and at one point it snowed for thirty-three hours straight.” It was a rough winter for the pond near the cottage his mother would rent. The pond is Greenberg’s “rightful hunting ground” therefore the fish were also his. He predicts it was the winter conditions that killed the fish or the copper sulfate from a few years back. Greenberg would eventually obtain enough money to buy a boat and would find a river downstream of his pond that led into the sea. On this boat he would begin to learn to navigate without a GPS, find fish, and what fish would come in during certain seasons associated with the blooming flowers. In his early thirties, he was back on the East Coast after years of traveling abroad. Greenberg decided to get back to his roots and go fishing again. He was surprised to hear that the fish he was used to seeing in that area and according to the blooming flowers were not as he had remembered. After talking to many fishermen along the coast he came to the conclusion that fish had been decreasing in returning numbers, decreasing in size, and a decrease in time to fish. That would be the beginning of his journey to learn about fisheries. 

As for myself, I learned about a position that had opened in ADF&G and I took it, mainly because I needed a job, not knowing I would be completely obsessed with the commercial salmon fisheries of area M after a few months. I’ve been lucky enough to experience some aerial surveys and some weir work. I didn’t believe it when people said “if you love your job you’ll never work a day in your life” until I started working for fish and game. The lifestyle of the job has really impacted my life and not just by making me change my major to fisheries. 

Based on the first few pages I would say Greenberg would answer our previous question by rating the global fish stocks at a 6. It’s definitely not what it used to be but not quite disastrous? I think he’ll end the book more pessimistic as there are so many more issues impacting the ocean and freshwater systems then there were before.
