Abstract

In this study, the effects of ultraviolet radiation on bacterial load and survival rates of Artemia at different densities (250- 4500 ind.ml-1) used in commercially marine fish production, and at flow rates (0.63- 1.01 – 1.55 – 1.98 lt.min-1) was determined. TSA agar and TCBS agar were used to calculate for total bacteria and Vibrio spp. bacteria, respectively. The mortality of the Artemia was calculated by light microscope. The Artemia density was estimated as 260±26 and 4500±412 ind.ml-1 during the experiments. The average load of the total bacteria was eliminated between 56.6±5.4% and 84.3±3.5% in TCBS agar and 66.3±9.8% and 77.9±3.8% in TSA agar. The average mortality of Artemia was obtained between 4.4±1.8 % and 9.97±6.61 %.

Key Words: Artemia, mass stock , UV, flow rate, bacterial load.
