The CRSP Central Database: Integrating Aquaculture Information

standardized methodology. The Database contains more than one million observations of pond variables obtained from over one hundred production studies conducted at PD/A CRSP research sites located in the Philippines, Thailand, Indonesia, Egypt, Kenya, Rwanda, Honduras, Panama, and Peru. The studies contained in the Database pertain to the tropical and sub-tropical production of tilapia, peneaid shrimp, and other warmwater culture species in solar algae ponds that receive inputs such as plant materials, inorganic and organic fertilizers, and prepared feeds.

Started in 1983, the Database was maintained by the Program Management Office of the PD/A CRSP at Oregon State University (OSU) until May 1993, when it was transferred to the University of Hawaii at Hilo to be managed by Kevin Hopkins. Following Hopkins' withdrawal from the CRSP in 1995, the program's Technical Committee voted in favor of a proposal submitted by John Bolte—Associate Professor in the Department of Bioresource Engineering at OSU—to move the Database back to OSU to be managed under Bolte's direction. After relocating to OSU in the spring of 1996, the Database went online in January 1997.

Doug Ernst is the manager of the PD/A CRSP Central Database and a doctoral candidate at OSUs Department of Bioresource Engineering. The following interview with Ernst took place at OSU in late November.
The PD/A CRSP Central Database is a centralized data storage and retrieval system for PD/A CRSP research and for other aquaculture research programs with compatible objectives and

How has the CRSP Central Database changed since coming online at OSU in January of 1997?

Originally, the Database simply stored raw data related to aquaculture production. Very little contextual support existed for this empirical
framework. The first step taken to address this problem was to integrate the Database with information about the materials and methods used to acquire the raw data. The second thing we did to provide contextual support for the Database was to link data to relevant publications generated by the CRSP and scientific journals outside the CRSP. Finally, we added profiles of the PD/A CRSP research sites that supplement the data with physical characteristics of the site and contact information. These additions were made so that end users would be
