Oxbows represent young types of reservoirs and
are characterized by a very fast evolution.
They are usually restricted into a littoral zone due to favorable light condition.
According to Camargo and Esteves (1995), limnological
features in oxbow lakes can be diverse depending onthe
environment and the study period.
Aquatic insects are the most commonly chosen group of fresh water organisms
used for biomonitoring as some of them are very sensitive
to stress from pollution and habitat modification.
The improvement and development of existing and new
biomonitoring tools using aquatic insects are a major effort
among aquatic entomologists (Carter and Resh, 2001).
In Asia, especially in developing countries physical and
chemical methods are predominantly used to assess stream
and river water quality.
Until present, there have been only
a few studies testing bioassessment methods in Southeast
Asia (Morse et al., 2007).
