Tilapia and other tropical cichlids are considered excellent aquaculture species in Mexico and other Latin American countries. The potential use of phytochemicals for sex reversal in tilapia could boost the marketability of this fish locally and internationally without the risk of potential human toxicity and environmental pollution caused by unregulated use of the synthetic androgen, 17 -methyltestosterone.
Ohio State and UJAT will diversify collaborative ties to include nutritional studies on amino acid and fatty acid requirements of larval and juvenile tropical gar (Atractosteus spatula or Lepisosteus tropicus) and other candidate species for the local aquaculture industry and for recreational fisheries in Mexico. Ohio State's Aquaculture Laboratory has the facilities to determine amino acid and fatty acid concentrations of fish feeds and frozen fish tissues.

The Aquaculture CRSP is pleased
to announce the inauguration of the new USAID Mission & CRSP Ambassador Program. The goal ofonhe program is to increase Mission awareness of the CRSPthat is, of the breadth of the CRSP network and the broad array of technical services and expertise available to Missions via the CRSP. As CRSP Ambassadors to the missions, researchers, primarily host country nationals, will serve as country and regional resource persons on aquaculture and related water issues. Kenya first, then Mexico, and now Thailand, Cambodia, Viet Nam, and Bangladesh are among the first countries with CRSP Ambassadors. Other countries are slated to come online soon.
Barry Costa-Pierce, Director of Rhode Island Sea Grant as well as Associate Director of the Coastal Resources Institute at the University of Rhode Island, visited Oregon State University in October at the invitation of the Aquaculture CRSP. Costa-Pierce spoke to an OSU audience in a lecture based on his 2002 book "Ecological Aquaculture." Costa-Pierce served as chair of the special panel commissioned by USAID in 2003 to conduct a review of the global fisheries and aquaculture subsector.
Bureau for Economic Growth, Agriculture, and Trade: Office of Natural Resources Management: Water: Aquaculture CRSP is one way of depicting our "location" at USAID. As a partner in the Water Team, the Aquaculture CRSP has invited Barry Costa-Pierce to make a presentation, "Aquaculture Status and Trends," in late January at a Water Team discussion group. The CRSP plans to invite other guest speakers to the same forum throughout the year.
The Aquaculture CRSP Annual Meeting will take place this year on March 6, 2004, following the annual meeting of the World Aquaculture Society in Honolulu, Hawaii. Main topics for discussion among the members of the Technical Committee will be policy issues and the updating of a series of white papers.

University, visited Universidad Juarez Autonoma de Tabasco (UJAT), Mexico, from 26 to 29 October 2003. During the visit he discussed and planned the experiments for the project "Use of phytochemicals as an environmentally-friendly method to sex-reverse Nile tilapia" with Host Country PIs Wilfrido Contreras-Sanchez and Gabriel Marquez Couturier. Dabrowski gave a presentation to UJATs academic community on "New developments in diet formulations for larval fish:
