One way to measure water transparency is done by using pieces Secchi (Secchi disk), which is a round pieces with a diameter of 20 cm made of zinc and painted white or black-white weighted. The tool is lowered into the water until it looks, its depth was measured, then lowered deeper. Furthermore, the chip is removed and when the puck ...

Chemical parameters of the water can not only be measured using digital equipment, but there is also a water quality measurement method using titration methods or staining. Here below is the equipment used in the measurement of water quality parameters by titration can be seen in Table 17. Table 18. Equipment used for the measurement of water quality by titration

If the concentration difference between the salt solution and fish body fluids is high, then the process of penetration of salt into the fish body will be faster. Salting methods can be grouped into three kinds, namely: 1) Dry salting (dry salting ) Dry salting method is salting method using salt crystals mixed with fish. Dry drying is done by ...
