Fishes are sensitive beings with as much right to life and freedom as other animals. To avoid cruelty and injustice, we need to avoid eating their flesh.
Partly because they think of fishes as unfeeling, many people who
otherwise avoid eating flesh continue to eat fish flesh and even call
themselves vegetarians. Biochemically and structurally a fish’s nervous
system closely resembles ours. Fishes possess abundant pain receptors and
produce chemicals known to counter pain and fear. When injured, they writhe,
gasp, and show other signs of suffering. Each year, the U.S. flesh industry
causes billions of fishes to suffer and die.
U.S. commercial fishers reported a 2001 fish “catch” of more than 8 billion
pounds. That figure doesn’t include billions of non-targeted fishes who also
were caught.
Long-lining is used to catch large fishes such as swordfishes, tunas, and
sharks. A long-lining ship unreels up to 40 miles of line bristling with
hundreds of baited hooks. Some long-liners don’t reel in their lines for
about 20 hours, so hooked fishes may stay impaled for nearly a day. Many
fishes who swallow the bait are hooked in the stomach; as they struggle, the
hook tears their insides.
In gillnetting, curtain-like nylon mesh hangs to a depth of 10 to 40 feet.
Gillnets range from several hundred feet to 40 miles long. Fishes swim into
the netting, which they can’t see. Unless they’re smaller than the mesh
size, they get no farther than poking their head through. When they try to
back out, the netting catches them by their gill plates or fins. Many of the
fishes suffocate. Others struggle so much in the sharp mesh that they bleed
to death, whether or not they’ve pulled free. Fishes trapped in a gillnet
that isn’t tended daily may survive for days, slowly dying. When they’re
pulled aboard, many fishes—beset by sand fleas—no longer have scales, fins,
or eyes. Many are dead, eaten away.
Worldwide, tens of thousands of ships trawl. In trawling, a moving boat
drags an enormous funnel-shaped net through the water. The tow forces all
fishes who enter the net into the tapered, closed end. Any fish larger than
the net’s holes is caught. Netted fishes are squeezed and bounced, together
with any rocks and ocean debris, frequently for several hours. Tumbled and
dragged, the fishes rub against each other. Often their scales and skin are
scraped off. Trawling also crushes, buries, and (by stirring up sediment)
suffocates fishes and other animals on the ocean floor.
Trawling hauls up fishes from a substantial depth. As water pressure
plummets, the volume of gas in a fish’s airbladder increases more rapidly
than the bloodstream can absorb the gas. This causes excruciating
decompression. Organs can hemorrhage from the intense internal pressure,
which frequently ruptures a fish’s airbladder, pops out their eyes, and
pushes their esophagus and stomach out through their mouth. Hauling up a
trawling net commonly produces a great froth of bubbles because the
airbladders of thousands of fishes have ruptured.
On board the trawler, smaller fishes are dumped onto chopped ice; most
suffocate or are crushed to death by layers of fishes who follow. Larger
fishes tumble onto deck. Fishes of all sizes are stabbed with short, spiked
rods and thrown into separate piles by species. Next they have their throat
and belly slit. If they’re still conscious and their belly is slit before
their throat, they feel severe pain. Maimed, dying, or already dead,
non-targeted fishes are tossed overboard, often by pitchfork.
Increasingly, the fish flesh purchased by consumers comes from
captive-reared, rather than caught, fishes. Millions of salmons are reared
in the U.S. for slaughter. Under natural circumstances they would migrate.
In captivity they’re confined to crowded cages that sit in coastal waters.
The water in the cages quickly fouls with waste and rotting food and often
lacks sufficient oxygen. Because of crowding and filth, infections and
parasite infestations plague intensively reared fishes, whose symptoms
include scattered hemorrhages; red, swollen, and oozing gills; eroded skin,
tails, and fins; and degeneration of internal organs. Fifty or more skin
lice may latch onto a caged salmon from head to tail and eat into the
salmon’s flesh. Afflicted fishes scrape themselves against their cage in a
futile effort to relieve the intense irritation.
Before slaughter, salmons are starved for at least a week because starvation
decreases feces and body fat. At slaughter they’re dumped into water infused
with carbon dioxide, which is painful to breathe. The carbon dioxide
paralyzes them, but most are still conscious when their gill arches are slit
for bleeding.
U.S. confinement operations currently hold hundreds of millions of trouts,
primarily rainbow trouts. Most are kept in shallow concrete troughs.
Typically, five or more foot-long trouts have one cubic foot of space.
Crowding and pollution reduce water’s oxygen content, so confined trouts
frequently mass—gasping—at inlet pipes or the water’s surface, where oxygen
levels are highest.
Like salmons, trouts are starved before slaughter, often for two weeks. They
won’t lose much weight during that time, so, in the industry’s view, why
waste money on feeding them? At slaughter, trouts are dumped into a mix of
water and ice. Struggling to breathe, they suffer until lack of oxygen
renders them unconscious in about 10 minutes. The mix is drained of water,
and the trouts suffocate. In 2001, U.S. slaughterers killed approximately 42
million trouts.
Currently, about three billion catfishes (mostly channel catfishes) live in
intensely crowded U.S. confinement facilities. Most are kept in ponds. In a
typical pond, a catfish 15 inches long has one cubic foot of space. Even
though commercial catfish foods are laced with antibiotics, and other drugs
are added to the water, a high proportion of catfishes die from disease.
Before catfishes are trucked to slaughter, they’re denied food for several
days, so that they’ll produce less waste and won’t vomit during transport.
Catfishes travel in tanks so crowded that three 15-inch fishes may have only
one gallon of water. En route, many die from oxygen deprivation.
At the slaughterhouse, catfishes may be confined to vats for days—still
without food—before slaughtering begins. Usually, catfishes are paralyzed by
a surge of electricity sent through the water in their container. Because
the current is not directed through their brain, they feel a shock. If the
current is too weak, they’re also conscious when a band saw or other blade
cuts off their head. In nature, channel catfishes can live 40 years. In the
flesh industry they’re slaughtered before they’re two. The catfishes killed
by U.S. slaughterers in 2001 numbered about 400 million.
Fishes are sensitive beings with as much right to life and freedom as other
animals. To avoid cruelty and injustice, we need to avoid eating their
flesh.
