Abstract:
Based on the adaption of fishes to their habitat, they are divided
into three ecological groups - marine, fresh water and estuarine or brackish
water forms. Estuarine fishes inhabit the less saline region of the sea,
estuaries and other inland waters. These fishes are more subjected to pollution
than fresh water fishes or marine fishes as they encounter pollutants present
in the outgoing river water and the incoming sea water during low and high
tides respectively. So, the study of the biology of the estuarine fishes has
become unavoidable to assess their suitability in aquaculture.
The development of both capture and culture fisheries related to any
brackish water system is dependent on the availability of scientific‘ data on the
various biological factors in respect of the different species. Such a study on
fishes will be helpful in formulating suitable schemes for the management of
brackish water for capture and culture fisheries. It was therefore felt that
a study of the biological and biochemical aspects of two estuarine fishes Megalops cyprinoides Broussonet and Scatophargus Bloch which are not
fully exploited in aquaculture programmes, was worth undertaking. The present
study is expected to advance our knowledge on the biology of the two fishes
which are very desirable for brackish water fish farming
