what is the difference between monitoring and maintenance of water quality such as pH,EC, Salinity and alkalinity in aquaculture and aquaponics.
Hi Abdelrazzaq,
Monitoring is routinely measuring water quality indicators (ie it is about data collection). Maintenance is keeping the water quality within the desirable range of each indicator for the species of interest (ie it is about managing water quality/growing conditions). Monitoring should be used to inform maintenance and management decisions. Monitoring alone is not management.
Maintenance of the water quality parameters is done based on requirement of the aquatic habitat and further on monitoring of the parameters.
Maintenance is regularly keeping it at desired levels and ranges while monitoring is regularly checking to know if the parameters are normal. For example, an aerator may be introduced or water replaced to correct problems with DO. That's maintenance. Monitoring will help unravel this situation. So monitoring helps in maintenance.
Monitoring is checking a parameter and maintenance is maintain your water quality as per your requirement depend on animal or organism
Developing and building a maintenance program to avoid unnecessary maintenance and to keep a condition log of the asset is important
Monitoring is observing, measuring and recording crucial parameters, such as oxygen content, temperature, for environmental parameters, but also of feed quantity and quality, fish growth etc.
Maintenance is the action you take to keep e.g. the environmental parameters at suitable levels for your fish or other cultured organisms to remain healthy and grow.
Monitoring should also help you to be economical with using resources for maintenance and avoid unnecessary intervention.
You want to record your parameters sufficiently frequently so that you have enough degrees of freedom for multiple regressions that help you with the interpretation of impact factors, especially if several parameters change over time.

The analysis of water-management issues and objectives is the basis for specifying the information needs. T
Monitoring is measuring and, hopefully, recording a number a parameters that will let you evaluate the quality of the water in your aquaculture operation. However, no action is taken further.
If you want to maintain the quality of the water in your aquaculture operation and, hopefully, in the environment in which it operates, you first will have to decide what values in your parameters are an indication of "good" quality. Then, you will have to take the appropriate actions to adjust/remediate so as to increase/decrease/stabilize some of these parameters to achieve the values you will have set to reach "good" quality in your water.
All the best,

Total agree with what Professor Thierry Chopin just replied. Maintainance need you "to do something" to keep the environment in a proper situation which is good for the cultured orgnisms, while through monitoring you can get the information about "what you did to maintain" is right or not.
Monitoring should be done for proper maintenance. Measuring different water quality parameters over the time is the monitoring. May be it is an observation. Keeping the optimum levels of those parameters is called maintenance. On the other hand taking the necessary actions to keep the optimum water quality.
Monitoring are the actions that are applied to supervise or control a situation through a device or monitor. I just watch and infer. Maintenance is applied to procedures, usually preventive, repair or restoration, which are applied to keep a system running. Establish actions.
Water quality monitoring, samples of water should be taken and transported to a chemical laboratory to analyze the hazardous substances
Monitoring and maintenance water quality are interrelated. In order to maintain desired quality of water regularly measuring/recording important water quality parameters is very important. Depending on the recorded parameters through regular monitoring, water quality parameters are maintained by various means such as water exchange/ addition of probiotics/addition of certain salts/improving aeration system etc.
Dear Al-Tawaha,
Monitoring is frequently measuring of water quality parameters in ponds and it’s important to maintaining regular charts or book keeping to determine the current and future condition in the ponds.
Maintenance based on activities to keeping the water quality within the desirable range of each parameter according to the present condition of water quality given by monitoring.
I agree with the answers but monitoring might not be enough. You need process control strategy to maintain continuously the needed quality of water. The controlled variable is the pH of water and you can manupilute the flow of the stream that could be used to adjust the pH of water.
Usman Atique, this is exactly the answer I gave a month ago. You should recommend my answer if you like it, not repeat it as if it was yours. This is unethical.
monitoring is frequent measuring at fixed time for important water parameters in other word is followup (either if it is good or bad) and maintenance is try to fix or maintain water parameters at acceptable level in other word maintenance needs frequent monitoring to detect any change
Physical, chemical, biological, and off-project parameters are identified to make up the monitoring plan for the water of fish aquaculture.
Water quality monitoring and management are both inter connected activities. In the case of normal aquaculture system the water quality monitoring is done with normal titration or kit method or digital water quality analyzers and the management is done using the chemical or physical methods.
Aquaponics being an integrated system, utilizes the plants and medium in the hydroponic bed to remove unwanted waste materials from the water to maintain an optimum water quality for the fish culture. so regular monitoring is done using the same methods to check whether the water quality parameters are maintained in the optimum range or not. if not then to find out the fault in the system and to carryout the corrective measures to manage the same in desired range. The maintenance can be done by following the regular treatment practice without affecting the balance of the integrated system.
Monitoring and maintenance of water quality are inseparable. In order to maintain water quality parameters within the desired level one should measure the water quality parameters by using physical/chemical/ electronic gadgets, etc. This to be carried regularly. This is called monitoring. Once water quality parameters are recorded, if they are not within the desired range suitable for cultured species, then need to manipulated by following suggested biological/ physical/ chemical, etc methods to bring the parameters within the suitable level.
Dr Harsha Haridas answer well explained with regard to Aquaponics.
Monitoring is just estimation of different water parameters.
Maintenance means as per species requirement correcting water quality by application of required materials. Like for 6.5 water pH you have to add lime in water to raise pH up to desired level at 7.5.
Water quality is the most important factor affecting fish health and performance in aquaculture production systems and fish farming. Therefore, the farmers should give attentions to the kind of water quality required for the fish under culture
Maintenance is keeping water quality parameters in a certain range whereas monitoring is checking the parameters to observe whether these are in a desired level. For example, monitoring water temperature is to check in what level they are whereas maintenance is keeping water temperature in a certain level by adding or removing heater or other devices.
Hope this helps.
If you considering to do an experiment, you have to maintain some parameters and some of them monitor (depend on the purpose of your experiment). Usually, maintaining uses to reduce the error between your treatments and replicates. Monitoring uses to see the difference of parameters between your treatments which was influenced by specific factor of the experiment.
monitoring is a process to be aware about change of parameters but maintenance is a process to stay them in a certain amount.
The first one is scanning the health and the later is remedial measures by applying chemicals/ organic substances
just you checking/examine water quality parameter is monitoring and maintenance means taking corrective action to maintaining required water quality
