Abstract
The effect of aquaculture, especially shrimp farming,
on agriculture has caused heated debate among
aquaculturists, agriculturists, and non-governmental
organizations. As data on the negative impact
of shrimp farming on adjacent rice fields are
not available, a study was undertaken in rice
fields skirting three shrimp farms: a semi-intensive
farm; an extensive farm; and a semi-intensive
farm with a buffer zone. The buffer zone was found
to be helpful in preventing salinization of the
adjacent agricultural fields and the Electrical
Conductivity (EC) values (less than 1) reported
were found to be harmless to the rice crop. Thus,
aquaculture and agriculture can coexist in coastal
areas if there are buffer zones in between.
