i agree with fishing with moderation. However, with the human population growing exponentially, fishing pressure has the potential to increase even more as we try to feed the growing number. Perhaps this is where farmed fish could be beneficial. I don’t agree with genetically modified fish, but thats not to say properly regulated farmed fish couldn’t play an increased role in the seafood industry.
I like this hashtag, i think it sums up a lot of whats going on. If we continue down the path we are on there may be extreme consequences. However, there is always hope. Hope that we will learn from our mistakes and hope that we may change the future for those who come after us. I don’t think it is ever too late to stop trying and if we make make meaningful corrections to our path, it is doable.
i like to go through the exam first as well. i try and knock out the ones i know first leaving me the remainder of the time to tackle the more difficult questions.
Ron, i’ve tried looking for the recorded lectures before with no luck. probably gonna have to ask peter where he puts them.
I like the concept of writing everything you can remember down to test your knowledge. i have done that a couple of times before, maybe i need to go back to doing that. i do have the bad habit of putting off studying though until a couple of days before an exam.
I think it is also important to note that pollock show genetic differences between geographic populations. This should come into play during the management of the stocks. If one area is being fished too heavily the genetic diversity within the stock is going to dwindle making the species more susceptible to disease or other factors.
i think another difference between the two can be seen in the number of nations fishing. The pollock fishery is mainly the US, Japan, and Russia, however, the cod fishery saw way more involvement from a larger number of nations. This led to even more difficulties in trying to regulate the fishery.
I fully agree with you on local fish, however, i do not think it is possible anymore. Society has generated an unrealistic sense of entitlement and telling somebody they can’t have access to a fish because they are not local is not going to work. Another pushback will be seen within the fishing industry itself, commercial fishermen will loose a significant market through this transition and whether or not it is good for the ecosystem it will affect their bottom line.
I tend to agree with you on this, it is important to not only protect the waterways but to also clean up the existing damage. If eliminating boating in these areas is not feasible, then perhaps a motor restriction could help. Initiatives to assist in clean up are also important and could prove invaluable to future generations of both fish and humans.
I like that you brought up the interviewing of Ted Ames. Local knowledge can be an invaluable tool when trying to identify historical populations. Science has not always been around in the capacity it is today, so it is important to take into account the first hand knowledge that fisherman can provide.
You brought up an interesting perspective about baselines shifting in the other direction. I had not thought about it going in that direction. This especially could be seen when it comes to invasive species. Rather than completely eradicating them a new generation could accept it as a new “normal.”
I like how you thought this through and scored salmon for each portion of the criteria. However, since we are talking about Atlantic salmon i would have scored them higher. Having the yolk sac attached to their abdomens provides them with valuable nutrients for the earliest parts of their lives. This, along with removing natural predators, drastically improves their survival rates in captivity.
I’m not sure i would say any fish has an “inborn liking for man,” however, Atlantic salmon have been known to be more docile in captivity with reports of them even approaching human caretakers once they relate them to food.
I actually think Solow got the definition backwards. Present populations should be using substitutes to ensure the natural resource is available to future generations. Rather than using up all of the natural resource and leaving the future with substitutes.
