Foamy Pond Waters

At a shrimp culture period, sometimes we often find a foamy pond waters phenomena. It is more clear to see at water wheel operation as well as water circulation process. Don’t be ever to considering that foamy pond waters is easy, because it can reasoning a serious problems for shrimps condition.

Foamy pond waters is one of practically indicators related with waters quality at that moment. This condition is signing for us that it already plankthon mortality happen within waters. Generally, foamy pond waters occuring process are, among others :

1. At the moment that water wheels be operated, it will seen waters color clearly that related with dominant plankthon within waters, this is signing that plankthons are in high plankthon density and “old” condition;
   
   
2. The foams begin appear as length as waters current that it caused by circle of water wheel, in this stage foams dimension is short. This condition is signing that at the moment is already beginning plankthon mortality;
   
   
3. The foams that caused by water wheel current more and more length and it will go along the side of pond. This condition is signing that plankthon mortality within waters more and more highly;
   
   
4. Waters transparancy is drop suddenly and at extreme condition it achieve to pond bottom (clear waters color). This condition is signing that it already a mass plantkthon mortality within waters (plankthon collaps).

In line with the discussion like mentioned above, foamy pond waters if not be handled quickly, it can becoming troubles for shrimp culture. Plankthon collaps in this case will intrude equally of waters ecosystem, in addition it also reasoning dirty bottom pond that caused by the settle of death plankthon.

In order to anticipate foamy poand waters, so technical treatment that could be implemented are, among others :

1. Continuous water circulation and it more increase as well frequency and volume. The main objective of this treatmentis to supply new plankthon seeds to replace the “old” plankthon within waters;
   
   
2. At the special condition is need plankthon seed inoculation method to make a new plankthon growth more faster;
   
   
3. Increasing dosage of fertilizer to spurring new plankthon growth until it can replacing the death plankthon quickly;
   
   
4. Maximizing water wheels operational.

The treatments like mentioned above is needed to prevent a suddenly plankthon collaps as effected from foamy pond waters that it can reasoning a serious troubles for shrimp culture.
