Researchers recycle aquaculture waste as fertiliser

Researchers are assessing the use of salmon farming waste as fertiliser, to minimise the impact of aquaculture on the environment and at the same time reduce agriculture production costs.

The INIA Remehue Regional Research Centre in Osorno, Region X, suggests using a remote controlled submarine vehicle (ROV) for removing the waste material that accumulates under salmon cages and then recycling the nutrients as fertiliser in agriculture and cattle farming.

Project director Marco Salamanca, a researcher from Concepción University said the research aims to "integrate and support two very relevant activities in the south of Chile - aquaculture and agriculture."

The research is being carried out by Concepción University, the Institute of Agricultural Research (INIA) and the Fisheries Promotion Institute (IFOP) and will cost CLP 460 million (approximately USD 619,000). Funding is being provided by the National Fund for the Promotion of Scientific and Technological Development (Fondef), which will contribute 53 per cent (about CLP 240 million) of the total investment. The remaining 47 per cent will be funded by participating private institutions and companies - Marine Harvest Chile S.A., Salmones Llanquihue S.A., Salmones Multiexport Ltda. and Aguas Claras S.A.

The Fondef D01I1113 project was launched by Cristián Lagos, on behalf of Fondef, Dr Franklin Carrasco, dean of the Natural and Oceanographic Sciences Faculty at Concepción University, and Dr. Julio Kalazich, director of INIA Remehue Regional Research Centre in Osorno.
