چکیده انگلیسی
Over a three year time period, the modified split-pond facility had net yields of hybrid catfish (Ictalurus punctatus â x I. furcatus â) that reached up to 11,416Â kg/ha/year; however, this includes several reports of fish kills. The present study experienced a minimum 15% reduction in net production compared to the recommended design values with a maximum potential loss of 54%. Ponds used an axial pump to transfer water between a 6:1 ratio of waste treatment area to fish grow-out area. Water flowed from the fish cell to the waste cell at a rate of 31.2Â m3/min and from the waste cell back to the fish cell at a rate of 0.78Â m3/min. Aerators used 5619-7492 kW-hr/ha which is more than the electrical use in traditional ponds (2238 kW-hr/ha). Even with the extra aeration, this study had at least one fish cell and one waste cell drop below a dissolved oxygen concentration of 2.5Â mg/L. These specific modifications may lead to poor survival and production in split-pond aquaculture and are discussed with best management practices of the recommended design.
