Salinity in conjunction with FOOD Penaeus Monodon

Salinity in conjunction with FOOD Penaeus Monodon.

Based on the tolerance of salinity, then Penaeus Monodon included in the group euryhaline sea, the sea animal that is able to live in fresh water. In some places, Penaeus Monodon found still able to live on 40 per salinity, but the proven experience slow growth. Value of salinity for optimal Penaeus Monodon is 15 - 25 per. If the value is too high salinity, feed conversion ratio will be high so that manages to, the volume of replacement water must be enlarged.

At high salinity, water animals, including the adaptation Penaeus Monodon will lose water through diffusion out of body. In this regard, many shrimp will be drinking water and avoid excess salt with a specific mechanism.

The overall mechanism that requires extra energy, so it can reduce the efficiency of feed consumed. In the business avoid excess salt in the body, stiffening eksoskeleton will occur that can cause skin fails to change. The only way to overcome the salinity is too high dilution with fresh water. To get the value of certain salinity can use the formula:

S = S1 V1 + S2 V2 / VI + V2

- S is the desired salinity (per)
- S1 is the high salinity of sea water / ponds (per)
- S2 is the low salinity of fresh water (per)
- VI is the volume of high-salinity water (m3)
- V2 is the volume of low-salinity water (m3)
