Composting fish waste and seaweed to produce a fertilizer for use in organic agriculture

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.
