Growth and development time of subtropical Cladocera Diaphanosoma birgei Korinek, 1981 fed with different microalgal diets

Abstract: The aim of this work was to investigate the growth performance of Diaphanosoma birgei fed with two Chlorophyceae algae, Ankistrodesmus gracilis and Haematococcus pluvialis using monoalgal diets and simpler mixed diets. D. birgei was daily fed on four treatments: 1) 100% Ankistrodesmus gracilis (Ag); 2) 100% Haematoccocus pluvialis (Hp); 3) 25% A. gracilis + 75% H. pluvialis (Ag-25+Hp-75) and 4) 75% A. gracilis + 25% H. pluvialis . The fecundity curve of D. birgei showed that the mixed feed Ag-25+Hp-75 and temp… Show more

“…Cladocerans can produce neonates every 2-3 days and can produce multiple offspring at a time; however reproductive rates are highly dependent on environmental conditions (Sipaúba-Tavares et al 2014). Cladocerans can reproduce both asexually and sexually, and often produce resting eggs at the end of each season and/or when environmental conditions become unfavorable.…”

“…The sediment of intermittent wetlands harbors resting stages of several species of aquatic invertebrates, which are able to resist to periods of hydric stress (Brendonck & De Meester, 2003;Gaikwad et al, 2008). The production of resting stages by aquatic invertebrates is an important strategy in response to a range of physical, chemical and biological stimuli such as lack of water, extreme temperatures, low levels of dissolved oxygen, as well as variations in photoperiod, competition and predation (Williams, 1993;Brendonck & De Meester, 2003;Williams, 2006;Sipaúba-Tavares et al, 2014). Within these communities, aquatic invertebrates (mostly zooplanktonic microcrustaceans) present low active dispersal abilities, thus resting stages enable long-term maintenance of a diverse range of species and genotypes, as well as their coexistence with competitors and predators (Santangelo, 2009).…”

“…La ausencia de desarrollo de la población de D. birgei podría estar vinculada a la dieta ofrecida ya que se ha observado que el alimento óptimo para esta especie es una mezcla de clorofitas (Sipaúba-Tavares et al, 2014). Según estos autores si la población es alimentada con un monocultivo aumenta su fase de latencia (nueve días).…”

“…Según estos autores si la población es alimentada con un monocultivo aumenta su fase de latencia (nueve días). La disminución repentina del crecimiento puede también estar vinculada a la liberación de metabolitos por parte de los individuos que incrementan los efectos en la limitación de alimento (Sipaúba-Tavares et al, 2014). Asimismo, la temperatura del experimento podría no ser óptima ya que en ensayos con otra especie se ha logrado el máximo desarrollo a 29 °C.…”
