Cultivation of the microalgae Chaetoceros gracilis to feed the rotifer Brachionus plicatilis
The microalgae Chaetoceros gracilis was cultivated to feed the rotifer Bra - chionus plicatilis . Microalgae and rotifers were grown separately, each for 10 days in a growing system volume of 62,5ml to 20L (1st phase). This was followed by 10 days in 250L (2nd phase), after 10 days in 1 500L (3rd ph...

| Resumo: | The microalgae Chaetoceros gracilis was cultivated to feed the rotifer Bra - chionus plicatilis . Microalgae and rotifers were grown separately, each for 10 days in a growing system volume of 62,5ml to 20L (1st phase). This was followed by 10 days in 250L (2nd phase), after 10 days in 1 500L (3rd phase). The growth rate exponential population at intervals of 24h for C. gracilis was 0,72, 0,30, and 0,28cells/ml to three phases of cultiva - tion. Within 24h the arithmetic growth rate for the population of B. plica - tilis was 330, 1 858 and 13 912rotifers/day in three phases of cultivation. Twenty-four hour intervals counts from the increasing number of organ - isms in the cultivation of microalgae, allows the prediction of a rotifer production necessary to feed a certain number organisms. |
