Atlantic Salmon

Who farms it? Mainly Norway, followed by Chile and the UK. Worldwide
production exceeds one million tonnes a year.

How? Juveniles are produced from eggs 'stripped' from female
broodstock by hand and artificially inseminated. They are reared in
freshwater tanks (as parr), then 'put to sea' (as smolts) in cages
housing 5,000 to 50,000 fish.

What's in it? The colourings astaxanthin (E161j) and canthaxanthin
(E161g) are used to dye flesh pink, though the permitted concentration
of canthaxanthin was reduced by the EU in 2002 due to links with
retina damage in humans. Fish are treated with antibiotics, some of
which may remain as residues, and routinely injected with vaccines.
The fungicide malachite green (a carcinogen) was banned last year, but
traces have since been found in four samples of Scottish salmon and
two from Norway. Because they are fed on fishmeal and oil extracted
from 'trash fish' living in polluted waters, farmed salmon may contain
cancer-causing PCBs, dioxins and mercury as well as pesticides. They
contain more fat than wild fish.

Are the fish harmed? Though intensive farms are cleaning up their act,
overstocking is still a problem. This contributes to the spread of
diseases such as ISA (infectious salmon anaemia). Fish are starved
before slaughter, then stunned with a blow to the head, followed by
gill cutting to bleed them to death. Some are anaesthetised in CO 2 ,
which irritates the gills, then bled.

What about the planet? Diseased salmon can easily escape from cages
and infect wild stock. Farmed fish that have lost their ability to
migrate can breed with wild salmon, diminishing their urge to spawn.
The chemicals cypermethrin, azamethiphos, teflubenzuron and emamectin
benzoate (used to treat sea lice), together with faecal waste, pollute
the oceans.

Rainbow Trout

Who farms it? France, Italy, Denmark and the UK. Britain produces
16,000 tonnes a year, or 35 million fish.

How? Young female brood stock are fed or injected with testosterone,
turning them into functional males; sperm from these 'males' contains
only X chromosomes, so resulting progeny are female (females mature
later than males, retaining better flesh quality). Equally common is
triploidy, where eggs are manipulated using heat or pressure to
produce sterile offspring; these grow more efficiently and cannot
breed with wild stock if they escape. Raised in freshwater tanks and
weaned on to fishmeal pellets, fry are transferred to earth ponds
('stews') or gravel raceways fed by rivers.

What's in it? The same E colourings are used for trout as for salmon.
Antibiotics and vaccines are routinely given for diseases such as PKD
(proliferative kidney disease) and ERM (enteric redmouth). Many trout
contain geosmin, a chemical produced by a soil bacterium which gives
the flesh a muddy taint, the result of poor water quality.

Are the fish harmed? Trout are kept at even higher stocking densities
than salmon, some equivalent to 27 portion-sized fish sharing a
bathtub of water. On muggy days, they gasp for breath. Fin damage and
injuries are common. Further stress is caused by grading, where trout
are pumped from the pond and filtered through grids to sort them by
size. Slaughter is by suffocation on ice (to increase shelf life),
though some favour CO +2baths or electrocution.

What about the planet? Trout may escape and breed with wild stock, or
spread disease.

UNQUOTE

Are increasing public awareness slowly. Other organisations are doing
their best to point out the problems and dangers, but as in many
things, money still rules.

There are very many people who simply refuse to believe what is
published on the matter anyway.
