Growth and reproductive performance of locally isolated brackish water rotifer (Brachionus plicatilis) feeding different micro algae
Population growth and reproductive capacity of brackishwater rotifer, Brachionusplicatilis, were evaluated, for a period of 8 days in a temperature controlled ( =25°C)microalgallaborarory, under three different algal feeding regimens. The algal speciesthat were tested are: (i) Chlorella sp. (T1), Tetraselmis chui (T2), Nannochloropsisoculata (T 3). The feeding density of each algal species was maintained similar as of4.5xW6 ceHs mi. The rotifer fed on T. chui showed the highest (p<0.05) populationgrowth (131.5 ind./ml), compared to that fed on Chlorella sp (45.67 ind./ml) and Noculata (43.44 ind./ml). The abundance of egg bearing rotifers was also higher (35.77%)with T. chuithan with Chlorella sp (27.76%) and N oculara (24.60%). The results ofthe present study indicate that T. chui could be the most suitable algal food for thestock culture of locally isolated rotifer B. plicatilis.
