Survey Procedures: Over 650 commercial trout producers in the 15 selected States were contacted between September 1 and September. Prior to the survey period, a list of all commercial operations was created in each of the 15 states. Information was collected by mail return, telephone interviews, and/or by personal interview. Great care is exercised to ensure that all operations are accounted for in the estimates. Reliability: Sound statistical methodology is employed to derive the estimates from reported data. All data are analyzed for unusual values. Data from each operation are compared to their own past operating profile and to trends from similar operations. Data for inaccessible operations are accounted for through the expansion of the reported data or by imputation based on individual historical data. Survey data are subject to non-sampling errors such as omissions and mistakes in reporting and in processing the data. While these errors cannot be measured directly, they are minimized by carefully reviewing all reported data for consistency and reasonableness.

Definitions

Foodsize: Fish that are grown commercially for food, usually ranging from 3/4 to 1 1/2 pounds and over 12 inches in length. * Catfish Production Estimates

Survey Procedures: About 937 operators in the four major States (Alabama, Arkansas, Louisiana, and Mississippi) were contacted during the first half of October by mail, telephone, and personal face-to-face interview, and 80 percent provided a usable report. An attempt was made to contact all known catfish producers during this time. States use every available source of producer names to make their list as complete as possible. Great care is exercised to ensure that all operations are accounted for in the estimates. Estimation Procedures: Sound statistical methodology is employed to derive the estimates from reported data. All data are analyzed for unusual values. Data from each operation are compared to their own past operating profile and to trends from similar operations. Data for missing operations are estimated based on similar operations or historical data. Reliability: Catfish production estimates are based on a census of all known active producers and, therefore, have no sampling variability. However, estimates may be subject to errors such as omissions, duplication, and mistakes in reporting, recording, and processing of the data. These errors are minimized through strict quality controls in the edit and summarization process and a careful review of all reported data for consistency and reasonableness. Definitions Used for Catfish Production:

Large Foodsize - Fish weighing over 3 pounds.
