The Undersecretariat of the Council for Planning and Action for Development (Copade) of Neuquén, Argentina, successfully completed all stages of the project for the development of low-cost feed for rural fish farming.

This initiative was presented by the Centre for Applied Ecology of Neuquén (CEAN), located in Junin de los Andes, and was joined by the Foundation Julio Palacios as a Technology Transfer Unit (UVT).

The idea of the promoters of the project was to evaluate the quality of the production of a balanced feed made from trout entrails and vegetable meal.

Subsequently, they identified its alternative use as low-cost aquaculture feed for family-type enterprises in Neuquen province.

This initiative was partially subsidized by a the Ministry of Science, Technology and Productive Innovation of Argentina (Mincyt).

This authority contributed ARS 56,800 (USD 7,200), money that made it possible to purchase important equipment (vacuum pump, a pH metre and an oximetre) for research carried out by the CEAN.

In total, the project required an investment of ARS 300,833 (USD 38,000).

The rest of the total of the money was provided by the provincial government.

The commercial feed is – largely – the most costly input that aquaculture production process must deal with, the provincial executive informed.

The technicians and researchers also intended to help partially replace the feed for trout, improving the economic equation of the small production system.

To implement it, the project was divided into six stages, one of which focused on transferring knowledge.

Therefore, the book ‘Small-scale trout breeding’ was written and published.

It included a chapter aimed at the development and use of silage as low cost balanced fish feed.

As part of the Rural Fish Farming Programme workshops for family fish farming entrepreneurs from Junin de los Andes, Zapala, Huinganco and El Cholar were carried in order to:

  • Explain the methodology for small scale trout farming on various types of ponds;
  • Evaluate the spatial feasibility to develop trout farms according to the physical-spatial characteristics;
  • Transfer the silage making process and its use as a food source for farmed fish.
