Pond Water Quality Management - Concept 02

Pond water can be analogued as a “home” and environment where the shrimps living and carry out living activities also interacted with other organisms. Pond waters quality management in line with shrimps condition and shrimps need is mean how to provide a living place for shrimps with the result that the shrimps become “feel at home” within it and living normally. In order to create that condition, then before prepared “a home” for shrimps, it’s need to reviewed characteristics and behaviours of shrimp , there are :

  1. Demersal. The shrimps is living at waters bottom, so waters quality management necessary to considering pond bottom condition in line with shrimps need.

  2. Nocturnal. The shrimps more active at night, with the result that the pond waters condition is need to be appropriated with process of biologies, chemistries, physic and ecology that occur within it especially at night.

  3. Phototaxis negative. The shrimps always avoid a light straightly. This characteristic in connection with pond waters transparancy management that it can be covered ligth penetration directly.

  4. Canibalism. A shrimp is canibal to others. In order to decrease canibalism then the pond waters need to be supported with sufficient natural feed stocks and bottom pond condition is possible for weak shrimps to take a shelter from prey.

  5. Moulting. This is a natural process for shrimp growth with shell change also as respons for drastic environment changes. Pond waters management must not shake to waters ecosystem balance in order to avoid massal moulting, because at moulting process a shrimp on weakest condition and very susceptible.

  6. Need level of shrimps to waters quality is change in line with shrimps age.
Pond waters quality management that not observe shrimp condition, shrimp need and shrimp characteristics will increase shrimp restless level within pond and the shrimps always try to come out from waters environment like this. At this condition, the shrimps indicate unnormally behaviour to show that waters quality is uncomfortable for them.Several parameters as indicator of waters quality, are among others :
  1. Waters transparancy.
  2. Waters color.
  3. Waters physic condition.
  4. Pond bottom condition.
