Optimization of indoor production of fresh water rotifer (Brachionus calyciflorus): A preliminary study
Recently rotifer culture projects were undertaken at selected places in Punjab province. Rotifers are fed on Chlorella vulgaris ad libitum and exact algal requirements are not cared for which increases the production cost of rotifers. Therefore in the current studies, algal cell requirement of Brach...

| description | Recently rotifer culture projects were undertaken at selected places in Punjab province. Rotifers are fed on Chlorella vulgaris ad libitum and exact algal requirements are not cared for which increases the production cost of rotifers. Therefore in the current studies, algal cell requirement of Brachionus calyciflorus was determined for its cost effective production and utilization of data acquired in similar studies or in commercial applications. Required number of rotifers were withdrawn from the main stock, divided into three groups and fed on known number of laboratory grown C. vulgaris. Left over cells were counted after 24 h in all the three groups and their ingestion and filtration rates were determined. Algal cell requirements of B. calyciflorus were therefore determined which came out 32977 to 35540 cells/rotifer/day. In the second trial rotifers were cultured in cow-dung media with or without supplemental aeration. |
