Prawn is a saltwater shrimp species. It is generally cultivated in coastal areas where tide is available in the river. Prawn farming needs saltwater throughout the year. So, select a place for prawn farming where saltwater is easily available for whole year.
Lobster is a freshwater shrimp species. The lobster farm should located in such place where it is very easy to supply freshwater. The great source of freshwater is pond, rivers, marsh etc. The lobster can also be cultivated by supplying water by tube-well. The lobster cultivated area will be facilitated by good transportation systems and availability of minnow.
Qualities of Soil
Pond with silt loamy and sandy loamy soil is very suitable for shrimp farming. It will be better if the surface of soil become plane and slightly sloping in one side. The soil with Ph level bellow 5 is not perfect for shrimp farming. The perfect Ph level for successful shrimp farming is between 5-6.5.
Qualities of Water
Qualities of water is very important for shrimp farming. Because if the qualities of water become not favorable for shrimp farming then all shrimp minnow will die in the water and this
will harm the farmer financially. Heavy and muddy water is very harmful for both prawn and lobster farming. Some physical and chemical qualities of water for shrimp farming are listed in the following chart.
|Name of the Qualities of Water||Favorable Rate|
|Dissolved Oxygen||< 5.4mg/l|
|Salinity of Water||0-4 PPT for lobster|
|10-25 PPT for prawn|
|Total Hardness||< 100 pm|
