Phosphorescency Pond Waters

Have you ever seen the pond waters was lightly on the surface like “fireflies” at night ? Don’t be impressed with this phenomena, because the waters with this condition is one of an indicator that it’s “dangerous” for shrimp within it.

Phosphorescency pond waters is more often found at dry season with a little rainfall. Some factors can reasoning a phosphorescency pond waters at night, there are among others :

1. Waters salinity level is high;
   
   
2. The plankthons within waters is dominated by dynoflagellata (a harmful plankthon)
   
   
3. Waters circulation is not enough

Phosphorescency pond waters condition if not to be handled immediately, it can reasoning a dangerous problems for shrimps, there are among others :

1. The shrimps color become pale;
   
   
2. The shrimps being convoy;
   
   
3. Shrimps appetite is decreasing, more over the shrimps is not eat anymore;
   
   
4. At a specific time it can reasoning hepatopancreas damage;
   
   
5. At extreme condition can reasoning mass mortality for shrimps

In order to prevent phosphorescency pond waters problems, the technical treatment that can be implemented, are among others :

1. When the pond waters salinity at high level, make waters circulation routinuosly with more frequency and volume then usually;
   
   
2. Reduce fertilizer dosage if the waters tranparancy is very concentrated that can reasoning a plankthon (harmful plankthon) dominancy

If the pond waters is already on phosphorescency condition, then technical treatment that can be implemented, are among others :

1. Total waters substitution gradually that unchangeable shrimps condition (it’s better to using “oplos” waters circulation method, there is throw and fill the water simultaneously);
   
   
2. If the pond waters volume is already substituted with the new water, then reduced waters circulation immediately;
   
   
3. Do plankthon seeds inoculation in order to substitute plankthon dominancy (dynoflagellata/harmful plankthon) with kind of plankthon that suitable for shrimps;
   
   
4. Do a routine fertilizing in order to stimulate the new plankthon growth;
   
   
5. Monitore toward change of condition after the treatment already given related with shrimps condition as well as waters quality.

In line with the discussion like mentioned above, there is better to us for bewaring to phosphorescency pond waters phenomena. One more, don’t be impressed with this phenomena, because the waters with this condition can reasoning serious problems for our lovely shrimps.
