The collapse of the Newfoundland cod industry should have taught us two things: that fishing should be regulated and that data can be misleading. The largest amount of the nails in the coffin of this fisheries is that the fishermen weren’t properly managed. When people first settled along the Eastern shores of North America, it was said that you could walk across the water on the backs of cod. Within a few hundred years, there were boats from all over the world fishing these cod, mostly off the coast of Newfoundland. These fisheries were poorly managed, especially with the technological advancements including freezer boats and sonar. The new technology made it easier to stay out longer without losing the fish and the sonar made finding fish easier than ever. Until the sixties, international fishing was allowed in Newfoundland and that was the worst decision because the international boats outnumbered the Canadian fleet. After these boats were no longer welcomed in Canadian waters, the damage had already been done. It took another 30 years to almost completely wipe out the cod with just local fishing. Fisheries managers were confusing data. Sometimes they were seeing hauls that said it was the end of the world for these cod, and other times is appeared that the cod were making a comeback somehow. Something that wasn’t factored for was the when and where. The larger hauls that the managers were seeing were happening during breeding season, when cod tend to mass together in huge schools that not only made them easier to find and catch, but also made the cod numbers seem much larger than they were. By the year 1992, cod had just about vanished from the waters off of Newfoundland. In conclusion, the two major things we should have learnt from the collapse of the cod fisheries in Newfoundland is that the fishermen should be managed and that the data should always be looked at with respect to factors that may not be openly represented on a graph. You could say that all of this is the manager’s faults, and you wouldn’t be wrong in any way.
After learning the heartbreaking story of northern cod of Newfoundland, it is time to reflect on what you think are the two single most important lessons from this disaster. In approximately 250-300 words, tell us what you think those two lessons are, and why they are so important. Push yourself to go beyond the obvious, such as “we need to learn to not catch so many fish.” While that is true, that is not terribly helpful. Which lessons can be applied to help us avoid this type of collapse again in the future?

Expect to see an essay question on northern cod on Thursday’s exam.
How do I find the FTT prompt?
If you missed the quiz, or if you are unhappy with your score you have a second chance!
Another version of the quiz is available for download, completion, and upload on Blackboard.
Using the honor system, take no more than 90 total minutes to complete your quiz, CLOSED BOOK AND NOTES.
Upload your saved work (verify it is saved in your PDF) using the link on Blackboard.
Remember to download and open the PDF in a viewer such as Adobe Reader. Filling in answers to the form while still in your web browser will not save your answers.
A warning to those that are retaking the quiz with the hope of increasing their score: I will use this score for your final grade rather than taking your best score. Thus, there is some risk in your choice.
Mt approach to studying in this class is a lot different then how I study for other classes. Fist off theres not really any homework you can go back and review on so I went to the class recording and skipped through to the parts that had the most information and just reviewed that. I also went to my notes and looked at those to remind myself of the small things I forgot.
Salmo Doemsticus: Domesticated Salmon
Salmo salar: Wild Salmon
Mart Gross, a conservation biologist is a person to raise recognition of a new species called “Salmo Domesticus” 1998, He stated, “Domesticated salmon are about as different from wild salmon as dogs are from wolves.” Like dogs, salmon have now become dependent on humans to survive.
This the first time I have heard the term “Salmo Domesticus” and my first thought was “must be talking about domesticated salmon.” As far as researching online I had a hard time locating articles using the term “Salmo Domesticus.”
The process started in Norway, a process that disrupted the wild salmon across the world. The process began to make salmon twice the size and grow faster therefore adding to the marketplace. The wild salmon gene is almost to extinction, farm-raised salmon are overtaking the wild salmon. Over the years I personally have seen salmon on the interior drop in size and numbers. Recently I was introduced to sea lice, a common problem in farm raising salmon.
It definitely is a curse to me, and how can it be solved?
When I look at both sides with an open mind I see that we can definitely put more salmon in the marketplace but at what cost?
Farming salmon is a risky business because it brings diseases from the hatchery to the open sea therefore spreading and harming wild salmon. Farming salmon erases the wild gene in the salmon and then what?
Salmon go to the sea to mature and when are done maturing and need to spawn then head to freshwaters to spawn. The curse lies in the removal of the wild genome and diseases that happen due to human failure.
I’ve heard you all loud and clear that the approach being used to organize weekly FTT topics and responses was confusing and leading students to miss assignments. Let’s adapt!
New topics that are pending your response will be ‘pinned’ to the top of the home page. You can click on that and enter your response.
Let’s give this a try!
This week’s forum post will require some additional effort.
Step 1: Read the paper by Nobel Prize winning economist Robert Solow. The paper is : sust-solow
Step 2: Write a response by COMMENTING on this post in which you compare and contrast the views of sustainability between Solow and Art McEvoy discussed in the Fisheries Management I lecture last week. Note this is a change from you creating your own post. This is a change in process to try and keep things more organized for all of us.
Step 3: In your post also discuss whether you think Solow and McEvoy would consider the Yukon salmon fishery sustainable if Chinook salmon catches could be substituted with chum salmon
A thorough response to this week’s prompt will be at least 250 words. As per usual, respond to at least two (2) posts by your peers by Wednesday at 11:59 pm by clicking the ‘reply’ button to a student’s post
My approach to studying is usually to read through my notes from whatever chapter/section a quiz is on and if needed, look up quizlets or make flashcards, although this isn’t that type of class. For this quiz I looked over my notes from all the past lectures, I usually go through them and highlight over things to remember them. There’s this tip I learned from my AP biology class in high school where you leave yourself questions in the margins of your notes when you’re taking them so that when you go back to study, you have ready made comprehension questions to go along with your read-through study routine. Another good method is to write a summary paragraph after your chapter/section notes to cement things in your brain by writing. Sorry this post is late, I didn’t know we had an assignment.
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.
