Introduction - PD/A CRSP 18th Administrative Report
PD/A CRSP Eighteenth Annual Administrative Report

Table of Contents Next Section


The Pond Dynamics/Aquaculture Collaborative Research Support Program (PD/A CRSP) conducts research that contributes significantly to the removal of major constraints to aquacultural development, thereby promoting economic growth and enhancing food security. This report describes the activities and accomplishments of the PD/A CRSP during the period 1 August 1999 to 31 July 2000.

The PD/A CRSP is funded by the United States Agency for International Development (USAID), under authority of the International Development and Food Assistance Act of 1975 (PL 94-161), and by the universities and institutions that participate in the CRSP. This cohesive program of research is carried out in selected developing countries and the United States by teams of US and host country scientists. Now operating under its fourth USAID grant since 1982, the CRSP is guided by the concepts and direction set down in the Continuation Plan 1996–2001, which was awarded funding under USAID Grant No. LAG-G-00-96-90015-00. This grant authorizes program activities from 1 August 1996 to 31 July 2001. An overview of CRSP history and how the program has evolved since its inception is provided in Appendix 1.

The activities of this multi-national, multi-institutional, and multidisciplinary program are administered by Oregon State University (OSU), which functions as Management Entity (ME) and has technical, programmatic, and fiscal responsibility for the performance of grant provisions. ME activities at OSU are carried out through a Program Management Office (PMO), which is supported in the task of program administration by three advisory bodies: the Board of Directors (BOD), the Technical Committee (TC), and the External Evaluation Panel (EEP). PMO staff as well as advisory group membership during the reporting period appears in Appendix 2.

Annual Highlights

Research and Research Support Agenda

Research conducted by the PD/A CRSP since 1982 has helped to remove some of the constraints facing aquaculture development. Still, aquaculture continues to be hampered in several important areas. In developing the Continuation Plan 1996–2001, the CRSP undertook an in-depth constraints analysis. That analysis led to the identification of a number of major constraints that limit the development of extensive to semi-intensive sustainable aquaculture systems. Chief among these were:

The Continuation Plan 1996–2001 responds to the first three of these factors by setting a research agenda that addresses constraints to aquacultural productivity, environmental effects, and social and economic aspects of aquaculture. The second three constraints are addressed by a research support agenda committed to improving human capacity development, information management, and networking. To carry out that agenda, the program includes a Research Support component comprising three efforts:

The PD/A CRSPs multidisciplinary team of researchers and advisors represents a wide range of US and international aquacultural experience. During the reporting period, participating US institutions included:

Research activities were conducted at host country sites in Mexico, Honduras, Peru, Kenya, the Philippines, and Thailand, at the participating US institutions, and with collaborators in Colombia, Nicaragua, and Malawi. Memoranda of Understanding, representing formal ties between US and host country institutions, which were in place during the reporting period include those between:

Research Program Framework

The Continuation Plan 1996–2001 program framework, and the foundation for the current portfolio of PD/A CRSP research projects, consists of two building blocks: research in sustainable production systems and research support activities.

The sustainable production systems research framework is organized into the areas of production optimization, environmental effects, and social and economic aspects. Each area is further subdivided into specific research themes, which are the thematic areas of research needed to remove constraints to the development of more sustainable aquaculture. The results framework for research areas as presented in the Continuation Plan 1996-2001 is summarized in Table 1, and the results framework for research themes is provided in Tables 2, 3, and 4. Research areas and their respective themes are listed here:

Research Area: Production Optimization
Research Themes: Pond Dynamics
Feeds and Fertilizers
Reproduction Control
Aquaculture Systems Modeling
New Aquaculture Systems/New Species

Research Area: Environmental Effects
Research Themes: Effluents and Pollution

Regional Analysis: Human-Environment Interactions
Decision Support Systems
Product Diversification

Ninth Work Plan

The Ninth Work Plan of the Pond Dynamics/Aquaculture CRSP was developed by the CRSP Technical Committee and describes activities to be conducted by the CRSP from 1 August 1998 through 30 April 2001. CRSP work plans have typically covered two-year periods. This holds true under the Ninth Work Plan for individual investigations, but while the overall time frame is greater than two years, no one investigation extends beyond a two-year period.

Increasing the time period of the overall work plan was necessitated by the CRSPs substantially reduced USAID annual budget allocation for years 3 through 5 of the Continuation Planthus the start dates of Ninth Work Plan investigations were staged over a nine-month period to allow for funding of as much of the original research portfolio as possible.

Despite the staged funding approach, the budget cut also necessitated major revisions to the portfolio to ensure adequate coverage of the critical areas within the newly imposed financial constraints, such as the elimination of the Global Experiment (see below) and other studies and curtailment of several research support activities. Ninth Work Plan research is underway in Mexico, Honduras, Peru, Kenya, the Philippines, and Thailand, as well as in the US.

Earlier PD/A CRSP work plansthe first through the thirdspecified identical experiments (called Global Experiments) at all CRSP sites to provide a baseline for comparisons among sites. This approach was changed starting with the Fourth Work Plan when different but related experiments were also conducted at the various sites. The particular topics studied at each site were based on the research and information needs in each country, as identified by the Technical Committee.

The body of investigations funded under the Eighth and Ninth Work Plans reflects the broadening of research as was proposed in the Continuation Plan 1996–2001 as well as increased integration among sites. In addition to prime site activities, CRSP research now underway includes a cross-cutting, thematic approach for investigations that may be conducted at one or more PD/A CRSP sites and whose results may have wider application than results from prime and companion site investigations. All Eighth Work Plan research was concluded in the reporting period and is described, together with research funded under the Ninth Work Plan, in this report.

The Program Management Office tracks work plan schedule and methods changes to assure continuing accountability for program awards. Reflecting methods and schedule changes to the funded research under the Eighth Work Plan, work plan addenda were printed in Spring 1998 and Spring 1999. Additional changes to Eighth Work Plan research as well as changes to Ninth Work Plan research will be documented in a forthcoming work plan addendum document.
