I like this hashtag because it can refer to the past and can be applied to the future. There were many changes, like you mentioned, that contributed to the demise of pollock in certain areas because advanced technology allowed for larger catches. Today, we have to worry about ocean warming and increasing human population and demand which is definitely a changing time for management.
This is a great hashtag. Fish stocks can’t be managed over decades at just one level because there are so many variables that control the health and size of fish populations. I agree that realizing different management should be used for different species would make a big difference in management success.
Going through the exam first so you know what’s coming is a great idea! Then you can more effectively budget your time. I definitely spent too much time on the graph since I couldn’t remember everything, so my essay wasn’t as detailed as it could have been.
I agree about not absorbing who the people were just from lecture. I should have reviewed each of them before the exam, like you did.
Since both species have similar behaviors and large ranges, I agree with you that we should apply the lessons from the collapse of the cod fishery so that the same thing doesn’t happen again in the case of pollock. Since the pollock fishery is young, there’s a better chance for us to create a fishery that will be sustainable for years and years given proper management is established.
It’s interesting how you compared the decline and growth patterns the pollock fishery is experiencing now to the final years where cod was profitable. Maybe we should take a step back and do more research so the past’s mistakes aren’t made again.
This is an interesting idea. I think having areas where boat traffic was limited or banned could help species that require certain conditions to reproduce or are heavily impacted by such traffic. However, managing these areas to make sure boats are avoiding them would be tricky, especially if it made a boats travel out of their way to reach certain destinations.
This is an interesting idea. In order to do this, it would require much communication between countries, but if it worked, it could help relive pressure on certain fisheries for sure.
Hearing about other people’s experiences with shifting baselines just in their own lifetime highlights how rapidly things can change. I agree with you that we need to start collecting data in order to create a baseline population estimate that future generations can use.
I agree that listening to older generations and taking into consideration their experiences is so important when trying to assess population health. Though not everyone is a scientist, they can still tell you if there were more fish than there are today. In the absence of actual historical data, their experiences are so valuable.
I agree with you that each species has pros and cons when considering how easy it is to raise them in captivity. It’s also important to consider, as you highlighted, how behavior changes when wild fish are placed into captivity, versus when they are hatched in captivity and then raised.
Your point about salmon possibly being more familiar with human interaction is very interesting. Though I still wouldn’t say that they have an “inborn liking for man,” it may be that salmon are more tolerable toward human interaction.
I definitely agree with your statement that there aren’t substitutes for biodiversity. It’s easy to become wrapped up in the thought that all species are here for human gain and the only reason to manage them and preserve them is so that humans can continue benefitting from harvesting. However, it’s equally important to consider the ecological importance of a species. They may be the species that an entire ecosystem hinges on, and by removing them, a whole ecosystem may collapse. Human gain is not the only thing that should be considered when thinking about sustainability.
I agree with you that right now AquaAdvantage isn’t sustainable. Changes need to be made if that’s the route we want to take, for example a different food source so AquaAdvantage salmon aren’t competing with wild salmon for food.
I agree that by implementing better food usage practices, we could support a lot more people on the amount of food available to us today. I think it’s also a good point that not all protein comes from animals. Though I do think that producing more food will ultimately need to happen to support the global population, looking for more sustainable options is a great idea and should be looked into!
