To make a completely randomized design about the effects of high salinity on goldfish, follow these steps:

1. Define the research question: Clearly state the objective of your study, such as investigating the impact of high salinity on goldfish.

2. Determine the variables: Identify the independent variable, which in this case is the salinity level, and the dependent variable, which could be the health or behavior of the goldfish.

3. Select the sample size: Decide how many goldfish you want to include in your study. A larger sample size generally provides more reliable results.

4. Randomly assign treatments: Divide the goldfish into different treatment groups, each exposed to a specific salinity level. Randomly assign the goldfish to these groups to ensure that any differences observed are due to the salinity levels and not other factors.

5. Control group: Include a control group that is not exposed to high salinity. This group will serve as a baseline for comparison.

6. Determine the salinity levels: Decide on the range of salinity levels you want to test. It is recommended to include a range of concentrations to observe potential dose-response relationships.

7. Apply the treatments: Expose each group of goldfish to their respective salinity levels. Ensure that the conditions are consistent for all groups, such as temperature, lighting, and feeding.

8. Observe and record data: Monitor the goldfish regularly and record any changes in their health, behavior, or other relevant parameters. Use standardized methods to ensure consistency in data collection.

9. Analyze the data: Once the study is complete, analyze the data using appropriate statistical methods. Compare the results between the different salinity levels and the control group to determine any significant effects.

10. Draw conclusions: Based on the analysis, draw conclusions about the effects of high salinity on goldfish. Discuss the implications of your findings and any further research that may be needed.

Remember to adhere to ethical guidelines and ensure the well-being of the goldfish throughout the study.
