Fish farms in Singapore
consumption of fish is estimated to be 100,000 tonnes per year of
which about 5% is accounted for by local foodfish aquaculture. This
is mainly from coastal fish farms. They produce marine foodfish
species like groupers, seabass, snappers and milkfish as well as
green mussels and crustacean (shrimp/mangrove crabs). There are
also freshwater foodfish farms producing snakeheads, tilapia, catfishes
and carps and other cyprinids. From

In 2010, there were 106 licensed coastal floating fish farms in

- Reduce costs
of searching, catching and transporting fish.
and predictable supply of fish. Not necessarily achieved as mass
deaths of stock can occur.
- Reduce overharvesting
of wild fishes. Not necessarily achieved as wild fishes are still
caught, to feed the farm fishes.

farm fishes which escape can threaten native wild fish.
- Farmed fish
are fed pellets made from other fish, depleting other fish species
on a global scale. Often the small fishes which are daily staples
of poor people are used as feed for larger farmed fishes which
are sold as luxury items.
- Setting up
and running fish farms can physically impact the surrounding habitat.
- No door-to-door trash collection is provided to any of the coastal fish farms licenced by Agri-food and Veterinary Authority (AVA). As a result dead fishes and other trash are dumped into the water. More details here.

can we do about this?
- Find out
where your fish comes from.
- Tell your
supplier and supermarket you prefer fish from sustainable sources.
- Eat less
- Eat what
you take. Don't throw away fishes! (or any food for that matter).
Many marine animals have died and people have suffered to put
that fish on your plate!
