Waters are one of very important factor for supporting shrimp culture process. Technically, a fine waters quality can becoming successfully determinant factor of shrimp culture process at one period moment. One of waters management system aspect is waters ciculation that is water substitution within pond which it objective is to improving waters quality in order to appropriate with shrimps need. In line with the objective of waters circulation, the matter that need to be attentioned is the waters quality that to be filled to a pond. If waters quality that to be filled to a pond is more poorer than waters quality within a pond, then it can make a problem to shrimps

Based on it natural source, waters within pond can come from marine/sea and river (it is not too far from marine/sea) and if it viewed from quality, waters that come from both of sources directly is fluctuated depend on climate/weather and it surround environment. In order to get waters input that it quality can undercontroll, so on shrimp culture, as technically is fine to provide a water resorvoir that it will be used as waters input source for some ponds. Based on this understanding, waters that will be filled on pond is not directly filled from natural waters source (marine/sea, river, etc) but it processed within waters resevoir first.

Related with shrimp culture technical, waters reservoir have an important mean for waters quality management, are among others :

Waters reservoir is a waters quality controller that it from water sources (marine/sea, river, etc). Like discussion mentioned above, the waters that coming from sources directly have fluctuation quality and depend on climate/wheather and it surround environment. The existence of waters reservoir is hoped to make water quality controlling more easier and it assisting on decision making related with waters ciculation;
Waters reservoir can be used as a water treatment experiment media that will be implemented to a pond. Technically, waters treatment is hoped to improved waters quality within a pond, but if the waters treatment obvious resulting unexpected ouput so it can influenced to condition and quality of shrimps within a pond. The waters treatment that it have experimented at waters resoirvoir first, what ever results of course it is not influenced to shrimps condition;
Waters reservoir can be functioned as plankthon seed source for pond others at waters within ponds is difficult to be growth (i.e. at rainy season). Waters condition like this, one reason of it is caused by plankthon availibilty within waters is minimized. In order to get plankthon seeds, so waters reservoir can be made as plankthon sourcer by give it a fertilizing treatment continuously as far as resulting expected plankthon. The plankthon seeds that stabilized growth within waters reservoir furthermore can be used as plankthon sources for others pond through “water inoculation” method.;
Waters reservoir can be made as indicator of a waters quality problem that it coming from common waters (marine/sea, river, etc). Generally, if common waters quality is reasoning a problem for biota condition that within it, so it will appeared immediately within waters reservoir. This condition is very dangerous to the shrimps if common water with quality like that is filled on ponds directly;
At the specific condition, economically waters reservoir can resulting added value to shrimp culture at that period, because usually within water reservoir also grow other water biotas that it have economic value.

Based on discussion like mentioned above, the waters reservoir undirectly function is a filter toward some problems that may be caused by a poor waters quality that it come from common waters (sea/marine, river, etc).

In line with the urgency and function of waters reservoir to shrimp culture process, so it is better to prepare one plot of pond that it be functioned to waters reservoir or be made special plot of pond with special function that is as waters reservoir.
