seven days of the pond's history. Water temperature, wind speed, realand predicted dissolved oxygen, transparency, water addition andpaddle wheel treatments, feed amounts, and memos are available.Function KEYS provide average values, listing of memos, and bargraphs of dissolved oxygen values. Press function KEY 1 (PRT) andthe screen is instantly printed.Based on DOM suggestions and SWQ data, the feed schedulermodifies the feed schedule. Often conditions, such as sustained calmwinds, require an across-the-farm proportional reduction of feed to allponds. It is not necessary to type in new values for all ponds. Referringagain to the SFA table, function KEY 4 (SFF) is a Scheduled FeedFactor. Changing this number changes the feed for all ponds. ChanNngit back resumes baseline feeding after unusual conditions pass. Feedscheduling is finished. The time required depends mostly on thenumber of SWQ screens examined. It is a very rapid process to movearound on the SFA table and modify values. Tables are an integral partof Pond Manager because they isolate critical management variables.As seen, the entire farm is surveyed and controlled from a singlescreen instead of the cumbersome line by line format commonlyfound in many data base systems.The next task is starting the feeding rounds. Pressing function KEY10 (RET) on the SFA screen brings back the first MAIN APPLICA-
