How often is the content of the Database updated?

The Database is updated anytime new data come in, which is usually about every six months. Submissions tend to coincide with the end of a work plan, as researchers are contractually obligated by the PD/A CRSP to submit data on current work plans before receiving funding for future work plans.

Data submissions for tilapia production systems outside the CRSP are encouraged. Intensively fed systems are of particular interest. I am currently talking with researchers in Louisiana and other southeastern states about such additions to the Database.

There is no data entry at the website, only data extraction. Data are submitted on a disk or via FTP. However, the website does provide researchers with a means of reviewing and changing the information in the materials and methods section.

What procedures are in place to quality control the data?

Researchers must submit data in a standard format, per data
submission guidelines, so our first
check involves making sure data
are in this format. Second we try to determine if data values fall within acceptable ranges. For example, if we find a pH below 5 or above 11, we know we have a problem.

Has the Database ever been infected by a virus?

No. We use anti-virus software to protect the Database from viruses. Our system administrator updates the software with the latest virus profiles as needed and keeps us apprised of software patches that might provide added protection.

Is the Bioresource Engineering Department involved with other groups in collaborative applications of the Database?

Yes. We are currently talking with ICLARM about a near future collaboration. We would like to integrate the upcoming CRSP data summary statistics with Fishbase—ICLARMs aquaculture and fisheries database. ICLARM would then serve as an additional publication outlet for the CRSP database.
When do you expect to have the summary statistics completed?

We expect to have the summary statistics by June 2000. What we will do is write programs in Visual Basic that read the Microsoft Access files and generate summary data sets. In addition to integrating this information with Fishbase, these treatment statistics would then be added to the Database website allowing users to choose between raw data sets and summary tables.

What do you have planned next for the Database?

Once we complete the summary statistics, we would like to focus our efforts on expanding the group of Database users to include people closely involved with end production, and educators and students of aquaculture science and engineering, rather than just basic researchers or modelers. This involves promoting the use of the Database by contacting people in the education, extension, and research communities—which is already taking place to some degree. We would also like to create a Database user manual that helps guide the implementation process by providing ideas for applications of the data.
