A team of researchers from the University of Cauca are working on the development of a new feed supply, which is likely to be more economical with regards to the red tilapia.
The aim of the research project, led by Críspulo Perea Román and Yeny Judith Garcés Caicedo, is to generate greater profitability from fish farming in La Salvajina, through the reduction of feed costs in maintaining the species.
The results obtained so far guarantee that the biological silage from fish waste is a good source of nutrition during the final phase of harvesting, say the researchers.
Moreover, by this novel method of feeding, the scientists expect to help reduce the environmental impact generated by the improper disposal of waste from fish farming in the area.
The Asubagroin group at the University of Cauca, have evaluated the apparent digestibility and zootechnical parameters measured in the fattening stage of red tilapia in metabolic cages.
Clench Perea said that they have developed a prototype of that type of cage to reduce the levels of stress on the fish that were evaluated. And also to avoid the loss of specimins and to reducie the breakdown of nutrients present in their faeces, mainly protein.
At this time, the researchers are monitoring some 8,000 fish: 6,000 tilapia and 2,000 cachamas (a type of freshwater pompano).
This research is part of a project titled 'the technical and economic assessment of by-products produced by transformation of red tilapia in La Salvajina through the ensiling process', implemented by the Regional Centre for Productivity and Innovation of Cauca (Crepic) and the University of Cauca, with funding from the Ministry of Agriculture and Rural Development.
