Culture of <i>Brachionus plicatilis</i> feeding with powdered dried <i>Chlorella</i>

Abstract

The rotifer Brachionus plicatilis was cultured with powdered dried Chlorella in treatment 1, live or fresh cultured Chlorella in treatment 2, and baker's yeast in treatment 3. All the jars under three treatments were stocked with B. plicatilis at the initial density of 10 individuals per ml. The water temperature, air temperature, pH and dissolved oxygen were within the suitable range for B. plicatilis culture. The highest population densities of B. plicatilis in treatments 1, 2 and 3 were 60000, 50000 and 30000 (individual/L), respectively. The powered dried Chlorella was comparable with live Chlorella and may be used successfully as a feed for B. plicatilis. (Bangl. vet.

Effects of dietary microalgae on fatty acids and digestive enzymes in copepodCyclopina kasignete, a potential live food for fish larvae

“…; Mostary et al . ). Moreover, the larval seabream Sparus aurata achieved a similar growth rate by feeding rotifers enriched either by live or dry N. gaditana (Cañavate & Fernández‐Dı́az ).…”

“…In hatchery, the unexpected crash of algal cultures will impact the live feed supply to zooplankton and negatively influence the fish production in hatcheries (Mostary et al . ). We found that the nutritional quality of copepods fed on dried algae was comparable to those fed on fresh algae especially in the EPA and DHA contents in coepods.…”

“…There is a motivation to identify which kind of algae that can be used to enrich or change the content of copepod nutrition. Most studies have used fresh algae, but there is little information for using dry microalgae to feed zooplankton (Lubzens, Gibson, Zmora & Sukenik 1995;Mostary, Rahman, Mandal, Hasan, Rehena & Basar 2010). Although non-living microalgae are unlikely to provide adequate nutrition for zooplankton growth and reproduction (Baer & Goulden 1998;Mostary, Rahman & Hossain 2007), dry microalgae is still a good option to feed copepods when the supply of fresh algae is insufficient (Mostary et al 2010).…”

In a recent study, the 20:1 N:P ratio in the culture medium favoured EPA production in Nannochloropsis oculata and the 30:1 N:P ratio favours DHA production in Tisochrysis lutea (Rasdi & Qin 2016).…”

Dinamica poblacional del rotifero Brachionus ibericus aislado de estanques para camaron, alimentado con diferentes dietas

“…Alternativamente, como lo indican los datos de la composición proximal y contenido energético de las dietas; las semejanzas registradas, pudieron deberse al contenido de cantidades similares de lípidos y energía, mientras que las discrepancias se debieron probablemente a las diferencias en el contenido de proteínas, con mayor énfasis en la razón proteínas/lípidos, puesto que Øie & Olsen (1997) reportaron que existe correlación positiva entre la tasa de crecimiento y el contenido de proteínas y la razón proteínas/lípidos de los rotíferos. Adicionalmente, las dietas Espirulina y Rotimac son microalgas secas que tuvieron menores valores en los valores de dinámica poblacional, lo cual es coincidente con los resultados encontrados en otros trabajos, donde reportan que las dietas secas inducen bajas tasas de crecimiento (Mostary et al, 2010).…”
