N2  - Thisstudy deals with the determination of availability of sugar beet molasses as anutritional enrichment factor for rotifer cultures. A series of experimentsunder varying conditions such as ratio of sugar beet molasses in the nutrientcomplex were carried out in order to determine the effectiveness of sugar beetmolasses as a carbohydrate and mineral source for the purpose of aquaculturaloperations. The culture water of Brachionus plicatilis with the salinity of 38% was treatedthrough mechanical filtration and UV sterilization. 1 T cylindro-conical tanks are utilized forrotifer culture. Parameters of culture water were stabilized at values asfollowing; Oxygen concentration:5 to 10 ppm, temperature: 270C and pH:6.8 to 7.4.Rotifers were counted by using Sedgewick Rafter Cell on a daily basis in orderto determine increase of number of individuals. The study was conducted as 3different trial groups, each consisting three separate tanks, so triplicatedeterminations were obtained. For the GroupI, 10% molasses by weight of Culture Selco Plus (200 gr Selco Plus+20 grmolasses per tank) was added 6 times a day with 4 hours’ intervals. For theGroup II, 20% molasses by weight of Culture Selco Plus (200gr Selco Plus+40grmolasses per tank) was added and lastly for the control group, Group III, no molasses has been addedand 200 gr Culture Selco Plus was only added per tank. The addition of molassesto nutritive complex has a decreasing effect on the number of rotifer andincreasing effect on the number of ciliate. From the study, it is clear thatsugar beet molasses should not be used as an additional nutritional factor forrotifer cultures due to its decreasing effect on the number rotifers andstimulating effect on the ciliate booming. Addition of 10% and 20% molassesresulted in 31.4% and 23.3% decrease in number of rotifers at the time of T3,respectively. On the other hand, it wasobserved that addition of molasses in the nutritive complex has not affectedon the percentage of rotifers bearing eggs.
