the color of pond water - water color criteria


Criteria pond water color that can be used as a reference standard in the management of water quality is as below:

1. Color dark green pond water, which means indicate a dominance of Chlorophyceae with more stable nature of the environment and climate change because they have the time a relatively long mortality. Growth rate and relatively fast development is the potential occurrence of plankton boom in these waters.

2. Color brown pond water which means showing the dominance diatomae. This type of plankton is one supplier of natural feed for the shrimp, so the rate of growth and development of the shrimp relatively quickly. The level of stability is relatively less plankton, especially in winter conditions with the high rainfall, so the potential collapse of plankton and if not carefully managed water quality stability will be volatile and would interfere with the comfort level in the shrimp ponds.

3. Color brownish green pond water, which means showing dominance happens is the combination of the Chlorophyceae and is stable diatomae supported by the availability of natural feed for the shrimp.

Standard color of pond water as described above is a practical reference for identifying species of plankton in an attempt detection of water quality problems at an early stage. In addition to these standard colors there are some pond water colors usually found in shrimp cultivation activities, which include:

1. Color yellow pond water, which means indicate a phytoplankton species dominance cyanophyceae. In conditions like these pond waters are usually more pale colored shrimp than is usually accompanied by a decrease in appetite shrimp and if not immediately anticipated may cause damage to the shrimp hepatopanchreas.

2. Color green pond water vanished, which means indicate a phytoplankton species dominance dynophyceae impact is relatively similar to point (1).

3. Color blue-green pond water, which means indicate a dominance of blue green algae relative impact equal to the point (1).

4. Camouflage green color, in this case as if the pond greenish but basically no / less contain plankton. This happens usually in ponds which contain the seeds was very poor but planktonya fertilization activities continue, so the resulting color is the color because of the weather. This incident can be identified by measuring the brightness of the pond waters are usually very high, or to see the color of the water in a water mill was operated.

Identify types of plankton in the waters of the pond in a practical way to see the color of the water as described above to be supported by observation and laboratory analysis on a regular basis to obtain more accurate results. This activity is done by taking water samples and samples of shrimp from pond map map-whether the problem or not affected by the problem, so the comparison can be drawn.
