As part of a larger study, the present work highlights the way fish specimens affect the parameters of the aquatic environment, which is essential in fish farming. Six common carp (Cyprinus carpio) were subjected to an experiment where they were transferred to new aquatic environments, while two specimens remained in the water of origin. Each individual modified the initial values of the aquatic environments by balancing them to create a framework conducive to their survival. During the experiment, no feeding methods were applied, and the individuals' intervention on the water was strictly observed. The results demonstrated the high degree of adaptability of the species, but there was also an early case of fatality, which was justified. The intervention of the individuals was highlighted by the value of the parameter PO₄, which exceeded the recommended value in aquaculture. However, the value was identical when each individual was removed from the experimental module.
