Use of solar energy in the production of channel catfish. Final report

PDF Version Also Available for Download.

Description

No catfish are grown commercially in eastern Kentucky due primarily to a growing season approximately three weeks too short to provide the minimum 180 day feeding season. This research project was designed to test the feasibility of using solar energy to heat pond water enough to lengthen the feeding season the required number of days. The procedure involved the heating of a small starter pond by covering it with a solar swimming pool cover. Fingerling catfish were stocked in the small pond in early April and transferred to a larger rearing pond in May when water temperatures in the larger ... continued below

Description

No catfish are grown commercially in eastern Kentucky due primarily to a growing season approximately three weeks too short to provide the minimum 180 day feeding season. This research project was designed to test the feasibility of using solar energy to heat pond water enough to lengthen the feeding season the required number of days. The procedure involved the heating of a small starter pond by covering it with a solar swimming pool cover. Fingerling catfish were stocked in the small pond in early April and transferred to a larger rearing pond in May when water temperatures in the larger pond reached 65/sup 0/ F. Oxygen levels were maintained at acceptable levels in the covered pond by frequent aeration. Water quality resulting from a prolonged spring drought and run-off from a pasture fertilized by chicken manure seriously affected the project. Other significant problems encountered included algae build-up and the accumulation ammonia and carbon dioxide in the water. Losses to fungus infection was the most serious problem encountered. Approximately 30 percent of the fingerlings died from this cause while in the small covered pond. After the fish were transferred to the large rearing pond, no further unanticipated problems were encountered. From the time the fish were transferred to the large pond they were handled in a typical open pond operation. At the end of the growing season in October, the fish had an average weight of 1.4 pounds.
