Where
seen? Groups
of these silvery fishes are frequently encountered in pools at low
tide on many of our shores. Elsewhere, they are found in mangroves,
estuaries and fresh water. They form groups during the day among mangrove
roots and submerged plants. They disperse at night to feed.
What are perchlets? Perchlets belong to Family Chandidae
(some place them in the Family Ambassidae). According to FishBase:
The family has 8 genera and 41 species. They are found in Asia and
Oceania and the Indo-west Pacific oceans.
Features: To about 10cm. Body nearly transparent covered
with thin scales. Thus it is sometimes called the Glassfish. Mouth
is upturned with a projecting jaw and large eyes. A single dorsal
fin, deeply notched before the last spine. These fishes are often
seen in small groups.
Sometimes confused with Mojarras
or Silver-biddies (Family Gerreidae) which have a single dorsal
fin that is not deeply notched.

What
do they eat? They eat tiny crustaceans such as ostracods
and copepods, insects and sometimes fishes.
Human uses: Perchlets
are eaten in some places and sold fresh or salted. They are also used
as bait.
Status and threats: Our perchlets
are not listed among the threatened animals of Singapore. However,
like other creatures of the intertidal zone, they are affected by
human activities such as reclamation and pollution. Over fishing can
also have an impact on local populations. |
