Some water quality parameters can be observed directly while doing sampling in the field, it was easy to have many supplies water quality digital and portable that can be brought directly to the field, even today already, and kits analysis of water quality so that it can simplify water quality measurement. Observations and measurements of water quality on the ground were able to obtain more accurate data on water quality values obtained so that the analysis would be conducted related to farmed fish life would be more appropriate.
But there are also some water quality can not be measured directly in the field, it is associated with the treatment, water quality measurement method that will be observed, observation time, this usually occurs in the measurement of parameters of water chemistry or biology.
Preparation tools and materials measurement of water quality
Various aspects of water quality parameters for aquaculture has a standard or range of values that can still support for the life and development of living creatures that are cultivated, along with measurement equipment can be seen in Table 17.
