The feed ration is estimated from the shrimp biomass in ponds, and intensive culture
requires more feed input. On the other hand, the
growth of shrimp in an extensive system depends fully
on natural food organisms, and in semi-intensive
culture systems, both supplemental feed and natural
food organisms are used [5].
According to International Union for Conservation
of Nature (IUCN & IISD) [6], shrimp farms on sandy
land utilize unproductive land and offer opportunities
for development of methods of shrimp disease
management. However, one of the biggest challenges
for shrimp culture is how to simultaneously overcome
environmental and economic concerns by
implementing management strategies to reduce water
contamination and sludge [7], because large amounts
of nutrient inputs are lost to the environment [1, 8]. In
response to this, enhancing nutrient recovery through
