fish. These were taken from Pacific 
Chinook salmon. They also added 
DNA from a protein found in ocean 
pout. These are an eel-like fish. This 
DNA means the GM salmon grows 
throughout the year.
The company calls the GM fish 
AquAdvantage salmon. Normally 
Atlantic salmon take three years 
to reach full size. The GM salmon 
grow to the same size in half the 
time. This much quicker growth 
means that the GM fish can be 
kept in enclosed tanks. The com­
pany has set up two o f these tanks. 
One is in Canada and the other 
in Panama.
Some people worry about what 
might happen if GM salmon man­
aged to get into the sea. There, they 
could spread their genes to other 
salmon species. However, the com­
pany says that this will not happen. 
The GM fish, it explains, will not 
be able to escape from the tanks, 
which are far from the sea. W hat’s 
more, only sterile female GM 
salmon will be produced. These 
fish cannot reproduce, or have their 
own offspring.
The world’s population is grow­
ing. So extra food will be needed. 
Many people therefore think that 
more GM ‘food’ animals will have 
to be produced in future. GM ani­
mals are also known as genetically 
modified organisms (GMOs). Not 
everyone agrees with GMOs. Sev­
eral large food stores in the USA 
have already said that they will not 
sell GM salmon. □
