Research sponsored by the CRSP and headed by Martin Fitzpatrick and Wilfrido Contreras-Sánchez was highlighted in a recent article in Aquaculture Magazine (Vol. 26, No. 3, May/June 2000). In his regular column entitled "Research Reports," author James Avault, Jr. highlighted seven of the nearly 400 reports presented at Aquaculture America 2000, held 14 February 2000 in New Orleans, Louisiana. One of those seven was Contreras, Fitzpatrick, and Carl Schrecks paper entitled "Masculinization of Nile tilapia (Oreochromis niloticus) by immersion in trenbolone acetate," presented by Contreras. The study examined immersion in trenbolone acetate (TA) as an alternative to administration of methyltestosterone (MT)-treated food as a masculinizing agent. While TA was not as efficient as MT in masculinizing tilapia, it may pose fewer environmental risks. Stay tuned for the upcoming PD/A CRSP Eighteenth Annual Technical Report, which will include a final report from this project, describing the study in more detail.
