This page contains a compilation of all my posts on the topic of (over)fishing so far. The issue is important as fish is an essential and rich food source, but is facing collapse if we do not act responsibly!
Aquaponics – using fish waste to fertilise plants
At the moment, I am researching the issue of lack of clean drinking water in the third world, a more heart-felt topic for me, but I will surely look more into aquaponics later, since it seems like a potent solution to plant farming in areas without fertile soil.
Here is the YouTube video where I had the topic introduced.
Fish farming – good or bad?
Fish farming can solve or alleviate many problems
in today’s society, most notably starvation,
but there is the question of what the consequences may be, and if they are
worth it. I will just give you some food
for thought (pun not really intended) about this issue, which might not be
as clear-cut as one thinks.
This post is more speculative, or theoretical if you will; it is not solidly
fact-based, as I have not done in-depth research on the topic. I merely present
my thoughts and ideas on the subject, and warn you not to take everything I
write for certain!
Fish farming, or aquaculture, is basically growing large amounts of fish or other
aquatic organisms in a controlled and (usually very) restricted area, either
with or without chemical aids to enhance growth rates and overall yield.
Aquaculture accounts for about 50 % of the world’s seafood today,
including both marine and freshwater animals. It is thus a hugely important global food source; what
happens within this branch can have a strong influence on food around the
world. This also shows how well-established fish farming is in the food
production business, so what we need to ask ourselves is whether we should
promote and develop it further, restrict it, or maybe abolish it completely. I
will not give my opinion yet; first, I want to present the pros and cons in a
neutral fashion, and conclude by evaluating which weight the heaviest.
You should note already that this is
essentially an issue of practicality versus ethics – do the practical
advantages of aquaculture outweigh the ethical dilemmas it produces?
The main practical advantage of fish
farming is its efficiency in food
production. So many people around the world are starving this very moment.
Fish is a highly nutritious food source,
rich in protein, good fats and vitamins, and is therefore a key part of any
healthy diet. However, many argue that farmed fish is less healthy than
free-living, caught fish, which tend to be poorly exercised and stuffed with
chemicals I have no clue what they do. Though, this strikes me as painting the
picture in black and white, since there are many ways in which free-living fish
can catch parasites, diseases, infections and environmental poisons – lead
being a notable example! Still, let us accept the view that aquaculture
produces food of lesser quality. After all, many of the free-swimming fish that
get ill naturally die and sink to the ocean floor and never make it to our
table, while it is more likely that whatever screening processes the fish
farmers make to inspect the quality of their fish before selling them makes a
mistake or two and lets some bad fish through.
However, those favouring this viewpoint are
missing something very important: overfishing
has severely reduced the natural fish stocks. Recall that aquaculture
generates about half of our fish; it is not only because it is a successful
method in itself, but also because wild-caught fish is in sharp decline. Fish
farming provides an essential alternative. It can help feed more mouths and give the
natural fish populations room to recover. Consider that the starving people
in the world will not be picky about the health of their fish. Indeed, the more
nutritious food they are given, the better, no question, but I think that in
this case the need for quantity is vastly greater than the desire for quality. Again, remember that 50 % of all fish food comes from aquaculture. Think about
what would happen if we cut that away in favour of the healthier wild fish: the
wild catchment rates would have to increase dramatically to meet our
ever-increasing food demands, and the natural fish stocks would plummet beyond
any prospects of recovery within our lifetime. In other words, we would have
good food for a short while, and then all be starving. So, aquaculture is a
viable strategy in the long run. When
it all comes around, two farmed fish probably fill your stomach better than one
wild-caught.
Thus, I think that the practical advantages of fish farming are rather clear. However, I do not wish to encourage expansion to the effect that all our fish is farmed. I imagine a scenario where farmed fish constitute the base of seafood, with wild-caught fish is an alternative for those that have the option to prefer it!
There is a final practical point worth to
think about: (farmed) fish may be a
better source of meat than cattle and other domestic land animals, since
they do not occupy large areas of
fertile land (domesticated grazers take up vast fields of soil that could
otherwise go to producing crops, fruits and other food or energy products), and
they produce far less greenhouse gases
(or maybe none at all) as metabolic by-products. Thus, expanding the fish
industry by means of developing the aquaculture to supplement not only the
natural seafood, but also other food products that are less environment-friendly,
could be wise in the long run!
However, we should first consider the
ethical issues of fish farming. Fish are, after all, living animals, that feel pain and distress probably not much different
from the way you and I. Therefore, I understand that many find the though of
raising individuals crammed together in containers, barely able to move as they
wish, and being fed food from God-knows-where with all sorts of unimaginable
chemicals. I would not wish such a gruesome life for anyone, if I had a say in
the matter.
But, as always with ethical dilemmas, it is
never black and white. Think about the people
that go hungry on this Earth. Think
about the poor fish farming entrepreneurs
that desperately need to make a business to support their family, as well as
give food to their community, and how opposition to fish farming would thwart
their hopes. Think about all other
organisms in the seas and lakes whose survival depend on the fish community –
imagine how many other animals would starve and die when humans deplete the
fish stocks, if aquaculture is banned on ethical grounds. Animal rights
advocates tend to forget about other consequences beyond animals suffering,
just as business people tend to forget about anything that does not fill their
pockets. Ethical debates demand all sides to understand all views and take all
arguments into account in order to make a fair judgement of what to consider
overall right or wrong.
Now, indeed, one wonders what rights we
have to impose such an appalling life on other animals – what rights we have to
cultivate other individuals to live for the sole purpose of growing to become a
succulent fillet on our plate. We should
respect other’s lives! No one of us would like to be in the fishes’ shoes,
and one should treat others as one wishes to be treaded by them. Having this
viewpoint it is easy to neglect all favourable aspects of aquaculture as
unimportant, if you only look at it in an absolute sense. It then all melts
down to whether the ends justify the means and all those other sorts of clashes
between subjective viewpoints that never lead anywhere useful.
Note that I am not saying that I do not
agree that fish farming is an immoral activity! I am merely saying that
denouncing it completely and definitely on that ground is irresponsible, since
the same argument can easily be used against them: consciously condemning millions of people to starvation
is also immoral!
What I want to say is that we have a responsibility to explore all
aspects of this issue, as it affects the lives of so many individuals –
humans, fishes, and other aquatic organisms.
I will leave my contribution to the
discussion there, and give you a few guidelines for more research, in case you
found these questions as interesting and important as I do. If you have spare
time, or otherwise, I strongly encourage you to go look the facts up for
yourself! It is better for you to explore on your own, rather than me telling
you what to think! Don’t you agree?
The Fisheries and Aquaculture Department of the Food and Agriculture Organisation of the United Nations (FAO of the UN) has,
among many efforts to promote high-quality aquaculture, developed and published
a Code of Conduct for Responsible Fisheries, not only providing guidelines
for good and viable aquaculture, but also the setting standards internationally for how fish farms should be
handled. I have not read it myself, but I would recommend you to skim through
it to perhaps get a general idea of what sorts of questions and problems this
organisation addresses, and how it intends to solve them.
Below are a few useful YouTube videos by
the FAO of the UN. These only give the ‘positive’ side of aquaculture, so watch
them with a critical mind.
MSC – Marine Stewardship Council
The MarineStewardship Council (MSC) is a non-governmental, non-profit organisation with the
objective to promote sustainable fishing
– that is, fishing within limits, so that the natural populations are
ecologically viable (long-lived). Overfishing
is one of the most pressing global
issues we must face in the near future, with the fish stocks thinning out
after many years of irresponsible fishing, and the human population ever
growing. Fish is a key source of basic and nutritious food around the world,
and many cultures, most significantly the Japanese, depends on a rich supply of
diverse fish.
We all want plenty
fish with out food, but if we keep catching more than what can be replenished
naturally, the fish stocks are in danger of total collapse. Image from http://www.actionforourplanet.com/#/overfishing/4569962196
The MSC gives the MSC Certificate to fisheries that meet their firm criteria for sustainable and responsible fishing. The fisheries are rigorously assessed against three main criteria:
- are they fishing at sustainable levels?
- does their fishing methods and levels have minimal impact on the ecosystem?
- does the fishery abide national and international regulations and laws?
The assessment is made by several independent
scientists, who make detailed checks and match the results against strict
requirements. If the fishery meets the standards, it receives the MSC
Certificate.
However, the really remarkable thing about
the MSC is that it does not end there: it traces the product through the entire supply chain – all the way from catchment to transport, storage,
preparation, packaging to selling – and ensures the fish is being handled
responsibly, and not mixed with non-certified seafood. Thus, the MSC
Certificate confirms that the fish you buy has been handled appropriately, from
the water to the shop.
The MSC logotype
certifies that the labelled product has been caught, prepared and transported
according to strict environmental standards, in particular responsible fishing
levels,
so that we ensure a continued supply of fish for future years.

I love salmon
above all fishes, but it is facing serious overfishing issues (though not close
to as much as other fishes). If I buy salmon bearing this logo, I am supporting
fishing methods that take care not to drain the natural fish stocks, so I can
eat as much as I want with clean conscience! Haha! Picture from
Fisheries who feel they are using ecologically sustainable and environmentally friendly methods can volunteer for screening by the MSC process. If they (manage to) receive this mark, their products will be more attractive, as the logotype ensures high environmental quality.
The MSC also actively seeks out larger companies and food chains and strive to impose
their regulations on these, in order to make larger impacts on the seafood
market. Two noticeable examples are Walmart, one of the larges
grocery chains in the US, which had 76 % of their sea food sales coming from
MSC Certified suppliers in January 2012, and keep pushing all their suppliers
to strive actively for achieving such standards; and McDonals, albeit
primarily meat-based, but which still is hugely popular, and has achieved the
MSC certificate at least within Europe. Such success stories for the MSC is
invaluable, both in terms of reaching closer to true impact on global fishing
standards, but also in terms of publicity – if these well-known companies
proudly display their MSC mark, it will draw people’s attention towards this
organisation.
Perhaps the greatest challenge for the MSC
at present is that it is not well known. From what I can tell, it has been
immensely successful, and is still growing purposefully, which is fabulous news
for the environment. When it comes to opening the minds of the general public
to its importance and its quality work and what its mark really means, however,
it is not as easy as it seems.
This is where we come in…
Tell your friends, tell your neighbours,
tell anyone you can think of about the MSC and spread its message and methods
around. Think for yourself about how
important fish is for you, and start looking for which fish venders near you
support sustainable fishing.
Here is a playlist with some good YouTube videos about the
MSC, which I strongly recommend you to watch when you have a bit of spare time.
It gives you the basics of the MSC purpose and method, as well as some striking
facts and thoughts to note. (The playlist can also be found on http://www.youtube.com/playlist?list=PLP2SgXNUR27CiAqACp-YQ7y8IPrZ7lBx4&feature=mh_lolz)
