Swiss Contribution

ZHAW’s Institute of Natural Resource Sciences (INRS/IUNR) is committed to the sustainable use of natural resources and that natural habitats for humans, animals and plants remain intact. The aim of good fish farming is to maintain high-quality water, strive for low emissions, energy optimisation and simplification of operational processes in order to enable sustainable fish production. This project is implemented in cooperation with the Asian Institute of Technology AIT, Smiling Gecko Cambodia and WorldFish organization.

Description

Aquacultures initiated by the Cambodian government in rural regions are intended to ensure a better food supply for the population in the medium term. The commonly used, simple paddle wheels or diesel-driven systems are inadequate for a good and cost-effective oxygen supply in order to successfully manage fish ponds. On one hand, the ZHAW developed Sun-Oxygen-System SOS, with pumps supported by photovoltaics, is used to guarantee efficient oxygen supply for fish ponds. On the other hand, the nutrient-rich water is used for irrigation systems in fields; representing an economic, ecological and social approach.
