Records kept by the United Nations Food
and Agriculture Organization (FAO) also indicate that of the
world's 15 main fishing regions, four are depleted and nine are
declining. This global fisheries crisis is primarily a result of
overharvesting. The world's marine catch has increased more than
four times in the past 40 years -- from 18.5 million tons in 1952
to 89 million tons in 1989, but that growth is at great cost to
the environment, and ultimately, perhaps to world food security.
Several decades of overfishing in most of the world's major
fisheries has pushed many commercially important fish populations
into steep declines Canada's northern cod collapse, for example.
Catches are falling, despite the fact that expanding fleets are
fishing harder, spending more time, effort and money than ever
before in trying to maintain them. Some commercially important
stocks are in such a critical state that all fishing has been shut
down, or sharply curtailed. Hundreds of millions of people
traditionally dependent on fishing for food and livelihoods face
resource depletion, competition from industrial and distant water
fleets, and loss of access to traditional marine food supplies.
The biological diversity of the world's oceans is threatend by the
highly competitive race to catch enough fish to keep pace with
rising international demand.
Rising demand and decreasing stocks have led to increased
mechanization, over-capitalization of the industry and the buildup
of excessive fishing fleets, particularly of the larger-scale
fishing vessels that are responsible for the bulk of overfishing
related problems worldwide. A modern 'factory' supertrawler can be
longer than a football field and capable of catching and processing
into various products up to 200 tons of fish daily. One of the
world's biggest trawl nets could encircle more than a dozen "jumbo
jet" Boeing 747 aircraft at its opening. Ships deploying such nets
have a capture rate of about ten tons of fish per hour.
Since 1970, the world's fishing fleet has expanded twice as fast as
world catches. The fishing fleet in China, the world's leading fish
producer, is now around six times the size it was in 1979. As a
result, excess fishing capacity has reached alarming proportions.
There are about 3.5 million vessels boats currently fishing in the
world's oceans. Intense competition between countries and rival
fleets over access to fishing grounds has sparked numerous
international disputes over fishing rights in recent years.
FISHING FOR PROTEIN
Since 1989 the world~s annual catch has been dropping. Many argue
that this decrease is an indication that fishing has oversteppped
natures~s limists.
The FAO warns that the rising demand for fish and fish products,
combined with shrinking global catches from declining stocks, will
soon lead to the point where there will be a shortfall of fish for
human consumption of more than 20 million tonnes each year. Average
annual consumption of fish caught in marine and inland waters could
fall from 10.2 kilograms per person in 1993 to somewhere between
5.1 and 7.6 kilograms by 2050. This threatens the one billion
people, mostly in developing countries, who rely on fish as a
principle source of protein.
WASTEFUL AND DESTRUCTIVE PRODUCTION
The increased fishing pressure and the competition amongst fishing
nations and their fleets severely stresses fish stocks and
the marine environment. The widespread use of unselective
fishing gear and indiscriminate practices result in one-quarter
of the all the fish brought on board fishing vessels each year
being discarded, usually dead or dying, back to the sea.
Commercial fishing vessels throw back on average about 27 million
tons of unwanted fish annually. That amounts to about half of all
the fish caught from the oceans each year that are consumed
directly by humans. Along with these, millions of other
marine animals are being incidentally captured and killed in
fishing operations.
DESTRUCTIVE FISHING GEAR
Some fishing gear is particularly deadly for certain animals in
some situations. Longline fishing boats kill many tens of
thousands of albatross each year in southern hemisphere oceans.
Driftnets indiscriminately killed millions of marine creatures,
while targetting for just one or two commercially valuable species.
Marine mammals are frequently killed in great numbers in trawls,
set nets and purse seine nets. In addition there is severe damage
caused by fishing operations that use destructive gear and
fishing practices, like bottom trawling, that physically disturbs
marine habitats such as the ocean floor, sea grass beds or coral
reefs.
THE POLITICS OF OVERFISHING
Today, there isn't a fishing region in the world that does not
suffer from fisheries management decisions designed to satisfy
short-term economic or political objectives (or both) rather than
protecting the marine environment and conserving fish
populations. The bulk of the problems stem from twenty fishing
countries whose fleets land 80 percent of the total marine catch
worldwide.

Commercial fishing in most of these countries has been very poorly
managed. Even in a few countries where relatively advanced
fisheries management systems have been in place for many years they
have, almost without exception, failed to control the conditions
and stem the abuses that lead to overfishing and destructive
environmental impacts. Indeed, in many countries, governments have
played an important part in fueling the expansion of excessive
fishing capacity and overexploitation by providing lucrative
subsidies, taxpayer funded handouts. On a global scale, these
destructive subsidies run up to $50 billion a year.
The chronic failures of fisheries management in European waters of
the northeast Atlantic and North Sea are particularly noteworthy
since this area has probably the longest standing and greatest
single concentration of fisheries research and management
institutions in world. Yet, Europe's fish stocks are plagued by
overfishing, and massive excess fishing capacity.
The member countries of the European Union regularly ignore
scientific advice when setting their annual catch quotas: when
scientists from the International Council for the Exploration of
the Seas recommended a 40 percent cut in the 1995 hake catch to
protect the stocks, EU fisheries ministers agreed to a mere five
percent cut. In the EU, as elsewhere, it seems that a fishery must
be proven to be on its death bed before any remedial action is
taken.
In the United States a similar picture of failed fisheries
management prevails. According to the National Marine Fisheries
Service (NMFS), the federal agency overseeing U.S. fisheries, 80
percent of the known commercially valuable fish populations (122
aquatic species) are currently either fully or overexploited;
67 species of these, among them bluefin tuna, swordfish, oysters,
hard-shell and soft-shell clams and red snapper -- are
overexploited. A further 79 species continue to be exploited
even though the status of their populations is unknown. Little
wonder why this is so. The country's eight regional fisheries
management councils are primarily composed of those interests who
benefit directly from increased catches: commercial fishers and
other industry user groups.
It does say much for fisheries management regimes elsewhere in the
world , if the European Union and the United States are considered
to be amongst the leaders in the field of fisheries conservation
and management.
Quite simply, nature's limits have been breached by too many
fishing vessels catching too many fish, very often in wasteful and
destructive ways, and it cannot allowed to continue if the oceans
and the human communities around the world that depend on them are
to survive. Governments and industry are responible for ensuring
swift action to bring about urgently needed reforms, including
substantial fleet reductions and substantial cutbacks in allowable
catches, the elimination of destructive subsidies, major
reductions in bycatch and waste, and more stringent environmental
controls over fishing operations. The full utilization of
available fish stocks and profit maximization for industry have
been the key goals of short-sighted fisheries development,
while protection for the environment has taken a back seat. This
has proven to be the formula for disaster in fishery after fishery,
the world over, with the disastrous consequences for marine
ecosystems and humanity already plainly visible around the world.
