Zooplankton growth in a Biofloc system with different carbon sources in a Cyprinus carpio culture


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

Abstract: Yucca, moringa, macroalgae flours and coffee residuals were used to determine zooplankton growth in Biofloc system flocs. Four Rotoplas ® water tanks of 450 L capacity were filled with 300 L and 25 juveniles’ stage of Cyprinus carpio were introduced with a mean length of 5 cm and mean weight of 2.10±0.44 g. Carps were fed with 5% of total weight of biomass with trout food pellets (45% of protein). The carbon source for each experimental container was supplied at a proportion of 0.001% of the total organism’s weight. Each 15 days a sample of 250 mL of Biofloc of each tank were taken and microorganisms were counted in five groups: ciliates and flagellates, nematodes, annelids, and turbellaria form. All carbon sources allowed the establishment of Biofloc system. With moringa and coffee residuals, the nematodes appeared until the seventh sampling (37 org mL-1 and 24 org mL-1 respectively); with macroalgae and yucca, nematodes appeared in the fifth and third sample, reaching the quantity of 50 org mL-1 and 110 org mL-1 respectively. With this study, vegetal origin carbon sources can be used with good results.
