July 2008 Catfish Feed Deliveries Down 9 Percent from Last Year
US - Total catfish feed delivered in the United States during July 2008 was 127,545 tons, down 9 percent from July 2007, but up 4 percent from the previous month. Foodsize catfish feed delivered totaled 124,467 tons, down 7 percent from the corresponding month a year ago.
Feed delivered for fingerlings and broodfish totaled 3,078 tons, down 56 percent from the corresponding month a year ago.July feed delivered to Mississippi catfish growers for foodsize fish totaled 65,177 tons, nearly the same as last year. Mississippi accounted for 52 percent of the total foodsize catfish feed delivered to U.S. farmers.
The other major States with catfish feed deliveries for foodsize fish in July and their comparison to the previous year were Alabama with 34,535 tons, down 7 percent; Arkansas with 16,137 tons, down 22 percent; and Louisiana with 2,757 tons, down 25 percent from last year.
Reliability of Catfish Feed Deliveries Estimates
Survey Procedures: All participating catfish feed mills are feed mills that produce and deliver catfish feed to bonafide catfish producers. Survey data for catfish feed are collected from feed mills by the USDA-NASS Mississippi Field Office, which is responsible for ensuring survey coverage is as complete as possible. Mills are contacted by mail, telephone, fax, or internet. Diligent effort is made to ensure that all operations are accounted for in the estimate.
Estimation Procedures: The "Catfish Feed Deliveries" report refers strictly to catfish feed delivered to bonafide catfish producers and excludes catfish feed delivered to producers of other species. The totals include both bagged and bulk feed. Prior to summarization, questionnaires are compared to previous reports for comparability. Estimates are made for feed mills whose reports are not available in time to be included in the release. Those mills are identified by an asterisk on page 11 of this release. Estimates are based on the mill's previous reports and current conditions. Published totals are a straight summation of the individual reports and estimated data.
If a mill uses a fiscal accounting system, proration is used to convert reported data to a calendar month basis.
Two unusual features of this report are worthy of note: (1) cooperating feed mills are listed by name, and (2) it is impossible for the public to infer the amount of catfish feed produced in each State. Since many mills deliver feed to more than one State and to growers of other species, any inferences about overall production per State or per mill are not valid.
Revision Policy: Revisions may be necessary in the following month's publication pending a review of late reports received from mills. Revisions to previous estimates are made to improve month-to-month relationships. Estimates for the previous month are subject to revision in all States and regions monthly totals. In February, all monthly estimates for the previous year are reviewed and subject to revisions. The review is primarily based on data that may have been received after the original estimates were published.
Reliability: Estimates are based on data from cooperating catfish feed mills, and therefore have no sampling variability. However, estimates may be subject to errors such as omissions, duplication, mistakes in reporting, recording, and processing of 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.
