As I posted earlier, and what seems to be common sense, fish our nonrenewable, once we run out that's it. We have seen this in the past in areas like Newfoundland, born and bred on fishing, when the Canadian government had to halt large fishing enterprises in 1992 for lack of fish. We see this currently across the world in places like Scotland, China, British Columbia (Canada)and Norway to name just a few. We even can see this in our supermarkets that now label if the fish was caught in the wild or in fish farms.
From the past post, creating fish farms probably seems like a good idea as wild fishing by Purse Steiners and Bottom Trawlers catch far more than the seas can handle. Perhaps by breeding fish in controlled 'farms' we wouldn't over catch or harm any other wildlife, like dolphins or turtles, that can get caught in nets? After all most of our meat comes from farms. But do you know of any problems or concerns with farming? What about the reason behind going organic? Why are so many people preferring organic food?
The reality (as I've come to learn) is that fish farms, though perhaps a good idea in practise, are causing more harm than good at the moment. The most shocking fact for me is that the fish people most like to eat e.g. salmon, tuna, need to eat other fish to survive (they are carnivores)so where do you think these other fish come from? That's right the sea. For every 0.5 kg (1 lb) approximately 1.5 kg (3 lbs) of fish are needed to feed them. Does this make sense to you as I'm a bit confused? To save the fish population we need to catch more fish? Hmmm.
Another concern is the same that happens in other farms: disease. Fish in tight pools, with little space to move, can catch diseases therefore antibiotics are needed. So now fish farms not only need more fish but they also need antibiotics? What about the fact that like chicken for example, some fish are 'genetically modified' in fish farms so they can grow bigger faster? How is adding all of these chemicals good for our health?
Lastly, there are many cases where the 'pools' break and the fish get out into the wild. Can you guess what would happen? They need to eat too.
Are you following any of this? So fish which are suppose to be healthy for us are now full of chemicals and they need more fish to eat which is reducing smaller fish populations anyways. Have I lost the good point of fish farms?
Now I don't want to sound all doom and gloom because actually fish farms could be a good idea. China has found a way to harvest fish like Carp and Tilapia which are herbivores (eat plants) or omnivores (which can eat either plants or animals) and therefore they do not need more fish to survive. The problem is people don't tend to favour these types of fish. I'm also sure that other fish farms are working on safer options as well but I suppose the point is why go through all of this effort? Couldn't we just support our small scale fisherman? The ones that fish sustainably and not target fish populations at risk? It seems to makes sense; why keep trying to put a plaster on the problem when we can just work on not falling down?
