# Optimize water quality and production: sample cases

Case 1:
In the documents below you will find information about feeding and water quality for different breeds at the Zone.College.
On August 10, the data was collected in connection with the feed rates and the results are striking. Production for a number of systems seems far from optimal.
- Study the data of the 2 documents.
- Is there anything to say about the quality of the data?
- Determine for which fish/ tanks production could be increased?
- What actions do you think have been taken when you look at the data for water quality?
- Would you do it differently? How?
- What kind of data would you like to have extra to make better proposals?

Case 2:

The learning outcome of this pilot week:

LO1 Interpret data on water analysis and make decisions according to production strategies.

The assessment criteria for pass:

1. Describe the chemical, biological and technical processes occurring in an aquaculture system (and how they affect water quality).

2. Explain the influence of water quality parameters on the production potential.

3. Propose possible adaptations in the production strategy in order to control water quality.

Below you will find data from Kardala LH. You can choose 1 system from this to check for yourself whether you are able to meet the criteria.

Probably you need more data. Specify the data you need and try to find the necessary information.
