In order to reduce costs in rainbow trout ( Oncorhynchus mykiss ) production, researchers from the Technological Institute of Tuxtepec (Ittux) have developed an aquaculture feed from the residues of beans.
According to Dr Jesús Rodríguez Miranda, leader of this research, the objective is to take advantage of the raw materials present in the region to generate low-cost food that does not affect the quality of the trout.
According to data provided by Dr Jesús Rodríguez, bean pellets (broken or husked) represent a loss of five per cent of the total annual production, which is why they decided to use this residue for the production of a trout feed.
The study was carried out in the state of Durango, which is the second largest producer of beans in the country, according to information from the Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA).
\"The idea starts from the need for producers to reduce production costs, so an economic raw material was used that does not affect the growth of rainbow trout. Much of the fishmeal was replaced with bean flour, without impacting the growth of the product,\" Dr Jesus Rodríguez said.
