TABLE OF CONTENTS Acknowledgement Introduction General ...

The higher the intensity of aquaculture, the more waste is accumulated. In the case
of shrimp farm effluent, pollution loading is considerably less than from domestic or
industrial waste. Although chemicals released into water ways can and do have an
impact on water quality, the use and release of chemicals in aquaculture are less
than in agriculture and most, but not all, are only marginally harmful to the
environment.
Impact of waste and nutrient loading on the environment
● Can cause eutrophication of water ways leading to plankton crashes and
depletion of oxygen
● Self pollution of aquaculture systems
● Increase in the concentration of ammonia and a reduction of oxygen in the
water ways reducing the carrying capacity of aquatic environments
● Excessive development of inland cage culture causes more significant
reduction in the carrying capacity of the aquatic environment than pond
aquaculture
