• Many factors must be considered when a farmer is deciding which species of shrimp he should culture. Due to its large size and high price, Penaeus monodon and P. indicus are generally considered for farming. It has also been seen that both these species are suitable for farming in Kerala’s environment.
• Apart from these candidate species other commercially important species such as Metapenaeus ensis, M. monoceros, M. brevicornis, Penaeus semisulcatus and P. merguiensis are also potential species that can be grown in India.
• Another potential candidate species that is flooding international market is the White leg shrimp, Penaeus vannamei.

• As per the directives of Supreme Court
  • Only traditional and improved traditional shrimp farming can be undertaken within the Coastal Regulation Zone (CRZ) with a production range of 1 to 1.5 t/ha/crop with stocking density of 40,000 to 60,000/ha/crop.
  • Outside CRZ extensive shrimp farming with - production range of 2.5 to 3 t/ha/crop with stocking density of 1,00,000/ha/crop may be allowed.

Methods of Harvesting

• Two methods of harvesting are generally practiced on farms.
• These are either by draining the pond and catching the shrimp in a bag net or by netting the shrimp within the pond.
• The proportion of soft shell shrimp should not be more than 5% at the time of harvest.
