calendar year 1991, the fourth year of a five-year program to be implemented during

calendar years 1988 through 1992. This program was preceded by a similar Cooperative

Agreement for calendar years 1982-87. The purpose of the current Cooperative Agreement

is aquacultural technology development Key activities include research on tilapia monosex

seed production, polyculture, and economic aspects of aquaculture; provision of specialized

information to users; international networking; and training and education.

Research was conducted on methods to improve the efficiency of monosex seed production

of tilapia. Specific topics investigated were hormonally induced feminization of tilapia (one

phase in the potential development of

brood fish that produce all-male offspring), hormonal

masculinization of tilapia

fry in open earthen ponds, and determination of minimum solvent

concentrations for preparation of hormone-treated feed to induce masculinization of tilapia


Research on polyculture focused on effective aquaculrirral utilization of deep watershed

ponds and benefits of simultaneous culture of the giant Australian freshwater crayfish and

tilapia. Both efforts will continue in the future.

Documentation of the economic performance of aquacultural development projects in

developing countries continued in 1991. A comprehensive document on aquacultural

economics in Thailand, Panama, Jamaica, Guatemala, Philippines and Rwanda was

fmalized. A description of family-scale fish farming in Guatemala, including detailed

financial and economic analyses, was completed in 1991 (and published in 1992). Plans to

assess the shrimp farming industry in the Philippines, with funding through a Basic

Ordering Agreement with USAID, were initiated in 1991; an aqmicultural economist was

included in the proposed team.

Information of a general and technical nature about fisheries and aquacultural development

was made available through publication of a newsletter, 15 technical guides for developers

and producers (English, Spanish, and French) and five fact sheets for decision makers in

development agencies. A network database of aquacultural specialists worldwide was

strengthened; negotiations were undertaken to include the International Aquacultural

Network in a more comprehensive database maintained by the university.

In 1991, 53 international students from 21 countries were enrolled in M.S., M.Aq. and

Ph.D. studies in fisheries and aquaculture. A comparatively high degree of direction,

supervision and assistance from faculty is required for those international students for

whom English is a second language. Cooperative Agreement funds gave substantial

support to this effort In addition, 26 internationals participated in non-degree training and

research in various aspects of aquaculture and fisheries, for which certificates were

awarded. Among these were three senior visiting scientists.

In 1991, fifteen ICA specialists at Auburn University provided 734 person-days of shortterm

work assignments in 14 countries. In addition, a large number of international service

activities was conducted on-campus and within the U.S. Partial support for these activities

was provided by the Cooperative Agreement

Work plans for 1991 anticipated expenditures of $272,999, including a planned annual

funding level of $255,000 plus. $17,999 estimated carryover. Actual expenditures for 1991

were $260,099 or approximately 7% below anticipated levels. Funds carried over have

been programmed for expenditure under work plans for 1992.
