Abstract: The present study was made with
Lepadella sp. rotifer using four experimental diets (
C. vulgaris, H. pluvialis, Haematococcus sp. and equal mix of these), for 60 culture days. Microalgae were maintained at a concentration of 0.5-1.0 x 10
6 cell mL
-1, pH of 7-8 and temperature of 25±2°C. The diet that show better organism density was
H. pluvialis with 1,870,727±125 org 20L
-1, while
Chlorella sp. diet showed the lowest density with 550,572±128 org 20L
-1. All diets showed significant differences (P<0.001) among them, regarding to their final densities. Ro value ranged between 30 and 93 new individuals per female.
H. pluvialis showed a Ro=93 org per female and an r=0.25. All diets presented a Tc value between 17.31 and 18.44 and a value of r between 0.18 and 0.25. This experiment proves that it is possible to manage the culture density of this rotifer, depending producer needs.
