Water
Marine species could thrive in a range of temperatures from
cool to warm. Farmed shrimp, on the other hand, grow better
in tropical climates such as Thailand's. Shrimp, in general,
are particularly sensitive to low concentrations of dissolved
oxygen in the water. Poor water quality affect their development
and survival. The tolerance for salt appears to vary among
species but high salinities tend to be more harmful than lower
levels.
Soil
For shrimp farming, soil is an important factor.If the quality
soil is not good enough, cultivation will be affected. Soil
that is too sandy (sand up to 80 % or more) will not hold
up as a dam for pond water. Soil that contains a lot of organic
substances will putrefy with time as the substances decompose
and poison the soil. The most appropriate soil to raise shrimp
in, especially Black Tiger is sandy soil with a pH level of
around 6.5 - 8.5.
One simple technique to test soil quality
is to collect samples from the surface up to a depth of about
1 meter. If the soil is yellow, there is more acid than necessary
and improving soil quality may be difficult. If the soil is
red and gray, the soil can be enhanced and used for raising
shrimps.
