The National Fisheries Institute (INAPESCA) developed biotechnology that will make it possible to produce rainbow trout (Oncorhynchus mykiss) neo-males for the first time in the country. These organisms have the potential to produce only female specimens of the species, which prove to be highly demanding in the Mexican market.

Female trout farming is more profitable than in the case of the male ones because during their development they make better use of the balanced feed and exceed the latter in size. Furthermore, the meat from female specimens offers greater consistency and flavour.

While this is the first experience in Mexico, the procedure has already been performed in Chile and the US, among other nations.

According to INAPESCA scientist Genoveva Ingle de la Mora, generating rainbow trout neo-males took four years of research and experiments with the species.

The pilot phase of this initiative involved three stages:

  • Getting neo-male specimens and the standardization of a technique consisting of histological cut for gender identification;
  • Performing continuous studies to evaluate their growth;
  • Generating females by natural fertilization.

Ingle de la Mora stated that currently they have over 200 neo-males available to generate increased production of rainbow trout females.

With these specimens it is expected that domestic trout producers adopt this biotechnology developed by INAPESCA.

The scientific team expects to get lots of 'pure female' specimens to be implemented in farms that have the necessary technological and sanitary conditions for the development of the resource.

According to the researcher, the neo male organisms derived from the investigations performed are on farms in the state of Mexico, in the technology transfer stage for replication in breeding units, reported the Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA).
