Laboratory controlled production of Lepadella sp. (Bory of St. Vincent, 1826), using three different microalgae and their combination, enriched with yeast


Author(s): Jorge Castro M, Germán Castro M, Andrés Elías Castro C and Jennifer Ramírez N

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 106 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.
