WATER QUALITY AND SOIL CONDITION OF FISH PONDS IN SOME STATES OF INDIA IN RELATION TO FISH PRODUCTION
Abstract
Maintenance of a healthy aquatic environment and production of sufficientfish food organisms in ponds are two factors of primary importance for successful
pond cultural operations. To keep the aquatic habitat favourable for existence,
physical and chemical factors like temperature, turbidity, colour, odour, pH, dissolved
gases like oxygen, carbon dioxide and also reducing gases Hke hydrogen sulphide,
methane working lethal on fish life, will excercise their influence individually
or synergetically, while the nutrient status of water and soil play the most important
role in governing the production of plankton organisms or primary production
in fish ponds. Rating of fish ponds on the basis of these factors is a difficult
problem because of the complexities influencing and governing these factors and
also for the fact that it is not possible to study the effect of any individual factor
under uniform optimal conditions. Nevertheless from a study of a large number
of ponds under diverse physical and chemical conditions it is possible to arrive at
some broad generalisation which can be gainfully used by fish farmers. It may be
remembered also that different fishes behave differently as to the suitabihty of
environmental condition and food habit. As the major carps, catla {Catla catla),
rohu (Labeo rohita) and mrigal (Cirrhina mrigala) are the widely cultivated fast-growing
fishes in India these have been always used as standards except when otherwise
mentioned.
