In
sluggish rivers, ponds and fresh water swamps there are many interesting
fishes. The cascadura is one of these.
Unlike
most of our fresh-water fishes, the cascadura or cascadoo, as it is commonly,
called, is covered with large over-lapping scales which make it hard to touch
yet afford it easy movement,
Its
mouth is on the underside tip of its head, which makes it quite suitable for
feeding off the riverbed instead of in the floating volume of the water. There are many strands around its mouth
similar to the catfish. These strands
are called barbells. The barbells are
very sensitive to touch and to its special foods. As a result, the cascadura uses its barbells rather than its
sight for feeling out its food.
This
unusual fish lays a nest of eggs, resembling a cluster of brown cane sugar,
onto water plants on or near the surface of the water. It appears as a floating nest of eggs.
Before
the eggs are hatched, the parent cascadura remains close about the nest to
protect it from other fishes, which may eat the eggs before they are hatched.
The
cascadura is a rare fish and is not found naturally in other Caribbean
islands. It is considered by some
people an ugly fish, but it certainly is not if you study it carefully.
This
fish is found in many of our sluggish rivers, ponds and swamps in places like
Barrackpore, Debe, Penal, South Oropouche, Plum Mitan and in some of the small
rivers along the Caroni plains. There
is a small species of this fish called the pui-pui or river gold fish. This makes an interesting aquarium fish.
