I agree with you. I didn’t know about tragedy of Newfoundland cod fishery before taking this class but I feel like more people need to learn about those past failure. Not only fishery or research people but general public need to be educated more about what had happened and what is happening in fisheries. Even if you don’t eat fish or live far from ocean, we all live in same planet and at the end, we will get some kind of influence from fishery failure.
I agree that farmed fish could be beneficial as human population grow further and decrease over fishing pressure but as we have discussed, there are also problems and concerns for farmed fish. Evaluating consequences of farmed fish before it cause any kind of issue for ecosystem or human body is difficult but very important. Advanced research for this area might reduce people’s concerns against farmed fish.
We took a lot of time for cod and salmon fishery and I thought I remember important things about it but before Exam, I went over discussion board little quick and noticed I actually forgot several key points. Then I made very simple bullet point list for the difference and similarity of those two fishery. If you know the key point, it is much easy to remember details too.
I totally agree with you. When you cram, you just forget everything after the exam and not going to learn anything actually.
I am from Japan and I eat those imitation crab thing all the time but I actually didn’t know that they are made from Pollock! They actually taste good for the price.
I like how you mentioned political real of both fishery and how they are stretched across several countries for similarities of both fishery. I definitely agree that.
I didn’t know trawling has that much negative impact on ocean. And I agree, we should rethink about how much damage that is causing. Not only how much fish we are catching but how we catch is important thing to consider too.
I have same idea with you that getting rid of mass industrial fishing might be solution, just we have to remember to consider about economical impact that could cause. If it produce too much job loss or money loss, I don’t think people want to implement that action. But when we look at long term, I think reducing over fishing pressure is as important as creating job for a lot of people.
I grew up in city so didn’t have much chance to feel those changes in nature. I guess it can be scary when you really feel somethings going on and fish start disheartening but no idea what is going on. I agree making population census is important because that can allow us to see the trend and use that for regulations.
I really liked your idea that well communication between fisherman and scientists can be possible solution for this. I agree that it is very important. Fisherman see and feels what is happening in real world but also scientists have access to look over the past and interpret what is happening. I think it is necessary for them to communicate well.
I liked how you compared their behavior change in wild and captive environment. I thought salmon can be better candidate but the details you brought up about sea bass characteristics are very important and was interesting.
I gave little higher score for salmon but I liked how you consider their transition from freshwater to salt water part. I didn’t think about it but I agree with you that it would not be that easy.
I also disagree with Solow’s idea that things can be sustainable if there are substitute. It just doesn’t sound moralistic. We have advanced technology that can provide alternative and that helps protect wild but original never be exactly same with alternative. If we lose them, we lose something valuable. So, I don’t think having substitute means we can spend or consume everything we have now.
I liked how you brought economics perspective to understand sustainability. Like you said, a lot of people maybe including me, enjoy the cheaper price of substitute fish and that decrease the pressure on wild salmons. But at the same time, the bland of wild salmon increase and I feel like rareness still attract a lot of people. Eel is one example. Japanese eel are endangered species because of over hunt and the price keep increasing every year. Most people can’t get it for daily meal but instead they eat eel from other places. Now Japanese eel is high bland and super expensive but people don’t mind paying a lot of money to taste the “real” one.
I also think this is the beginning and human will keep trying to seek the way to produce food more efficiently to feed this increasing population. But I still doubt if our technology can keep up with our too rapid population increase.
