Abstract
The fishing sector produces large amounts of waste in fish markets and processing industries. These by-products are mainly used
in the manufacture of fish meal. However, there are other potentially valuable uses. One low-investment possibility is the
elaboration of agricultural products by composting the fish remains with other marine materials such as seaweed.
The main purpose of this work was to obtain a fertilizer suitable for use in organic agriculture, by composting a mix of seaweed
and fish waste.
