I must say, after arriving in Ireland two weeks ago, what a beautiful, green and relaxing place to be. I came here two weeks ago in an attempt to try “wwoofing,” but to be honest, have had a much different experience that I expected. That being said, I am having a great time and I have met some interesting and lovely people.
Seeing the ocean from my room has inspired much reading and research and conversation about fishing, more specifically, sustainable fishing. Small seaside villages inevitably rely on fishing as food and clean water for leisure and tourism, so, being surrounded by small seaside villages at the moment has allowed me to learn a lot about what the oceans mean in the simplest of ways.
If I were to cut to the chase, I recently read a report published by the University of British Columbia’s Fishery Centre saying that by 2050 there is a good chance that many of the ocean’s large fish species could be extinct. These fishes include some of our favourites – tuna and cod – as well as some sharks and grouper. When large predatory fish such as these are removed from an environment, it allows smaller fish species such as anchovies and sardines to flourish. Unfortunately when there are many small animals in the absence of predators, these populations are much more prone to collapse by disease and massive die-offs; these conditions are then optimal for algae blooms or bacterial growth, resulting in deoxygenated water that is unable to support much life at all. These are called “dead zones.”
The problem is, in the simplest terms, over-fishing and improper use of the oceans resources. Basically, when a large fish population is found, all adults are fished, leaving nothing by way of reproductive individuals to replenish the population successfully. Combined with this is the fact that most of the fishing methods employed are extremely environmentally destructive. One problem, bycatch, is the unintentional catching of fish not necessarily used for anything which by definition exceeds the amount of target species caught in the process. For example, shrimp trawling results in 20kg of other fish species killed for one kg of shrimp. Well, not even just fish species, but also turtles, sea horses, dolphins, whales, you name it, it somehow makes its way in there.
Farmed fish also comes with its fair share of problems. Animal welfare is just one, but there are also large issues with contamination and damage to local natural ecosystems and habitats.

But as with most bad, there is good. There is always a way the average person can help. In Canada, http://www.seachoice.org/ is an organization that promotes sustainable fishing and seafood consumption. There is a published list of the best seafood choices – what it is, and how it’s caught. But it might also be worth it to try out the little guys that nobody likes! Anchovies, sardines, mackerel are all really delicious and deserve the same attention as your tuna sandwich.
Unfortunately, fishing is an extremely complicated topic and one that I am in no way 100% informed about. However, I am learning, and I think that it is worth my attention. I hope that more people become aware of just how fragile our oceans are. Think about how by the time the next generation grows to be adults they might never even get to try all the delicious things we enjoy today because we are enjoying them too much.
