4. Conclusions
Co-composting of fish offal with drift-seaweed and pine bark allows to reduce greatly the volume of fisheries byproducts.
In the course of two months from the beginning of the experiment, a stable product is obtained. This
product might be used as a fertilizer in ecological agriculture systems, as it is of natural origin and has no
limitations.
