In addition, thanks to the way the work was designed, fish farmers can use the data compiled as basic documentation for subsequently processing the waste discharge permit.

Conclusions:
The results obtained show that only the waste products generated by type-III installations (semi-intensive farming) discharge certain pollutants into the environment.

Thus, in-depth supervision of certain aspects should continue. This includes monitoring the behaviour of wetlands with regards to the treatment of water from cultivation before it is discharged. Fine-tuning these aspects can guarantee the minimization or elimination of possible pollution in the waters of sensitive habitats considered Sites of Community Interest.

As well as studying the behaviour of semi-intensive facilities located in Sites of Community Interest in the South-Atlantic region.
