“…Baker's yeast has positive effect on population growth in rotifer culture, but it induced lack of essential nutrients in rotifer biomass due to the deficient nutrient profiles. Two microalgae, Desmodesmus armatus and Acutodesmus dimorphus , were evaluated for Daphnia magna in comparison to baker's yeast diet and interestingly Daphnia magna fed baker's yeast resulted higher total lipid accumulation in their body with a level of 11% (Cheban et al, 2017). In our study, Daphnia fed baker's yeast diet showed moderate level (7.33%) total lipid accumulation in body of daphnia.…”

“…Several diets have been evaluated for daphnia nutrition such as baker's yeast ( Saccharomyces cerevisiae ) (Cheban et al, 2017; Munirasu et al, 2016), microalgae (Jorge et al, 2016; Stevčić et al, 2020), fermented probiotic bacteria (Herawati et al, 2018) and bacterial strains (Marinho, 2017). Among them, microalgae have some advantages such as balancing water column with reducing bacterial community comparing to other microparticulate diets and bacteria for long‐term culture purpose.…”

“…Among them, microalgae have some advantages such as balancing water column with reducing bacterial community comparing to other microparticulate diets and bacteria for long‐term culture purpose. Due to the high content of enzyme and water content, microalgae can be ingested and digested very efficiently by the live prey (Cheban et al, 2017). There are many microalgae species that vary in size, shapes, chlorophylls, pigments and nutritional values (Hemaiswarya et al, 2011; Peltomaa et al, 2017).…”

This research evaluated the growth, survival, proximate and fatty acid composition of water flea (Daphnia magna) fed baker's yeast (BY) and three types of microalgae diets. In this study, two freshwater microalgae; Botrycoccus braunii (BB) and Chlorella vulgaris (CV), one marine spray‐dried microalgae, Nannochloropsis oculata (SDN), and baker's yeast were evaluated for herbivorous zooplankton Daphnia magna. Survival, reproduction and population density of Daphnia magna have been studied. Daphnia reproduction was enhanced by utilization of baker's yeast diet with increasing egg number, juvenile and adult female numbers among treatments during the experimental period. Daphnia fed SDN diet increased egg number only 7th day of experiment. Population density and survival was positively affected by utilization of baker's yeast at the end of the experiment. Protein levels enhanced by SDN diets while Daphnia fed Botrycoccus braunii diet showed the highest lipid and EPA content in Daphnia. Overall, each diet improved different part of nutrients in Daphnia biomass.

“…Furthermore, proteins, lipids and carbohydrates are also important since these nutrients are essential molecules and reserves necessary for the enhancement and the effectiveness of growth and reproduction [35,64,65]. Although daphnids can accumulate large amounts of proteins, this content can be influenced by the age of organisms, the diet provided and the number of eggs produced [66,67]. Protein content reflects the entire physiological state of the organism and a measure of its energy balance [68].…”

Background: In the wild various organisms contribute to daphnids diet. This study, intendeds to evaluate the potential of the concentration of Rhodopirellula rubra as a single or supplementary food source for Daphnia magna. Methods: Feeding assays were performed according to standard guidelines for chronic assays (21 days), and life-history parameters and several biomarkers (protein content, oxidative stress, energetic reserves and pigments) were measured. Five food regimens were conducted with 20 individual replicates (A -R. subcapitata; 0.2 -suspension of R. rubra at 0.2 arbitrary units (AU); 0.4 -suspension of R. rubra at 0.4 AU; 0.2+A -suspension of R. rubra at 0.2+alga; 0.2+A-suspension of R. rubra at 0.4 AU + alga). Additionally, the effects of three diets (A, 0.2, and 0.2+A) on the longevity of D. magna were assessed. Results: The five diets showed a different C, N, and carotenoids composition, with an increase in the mixed diets. The results confirmed that the mixed diets improved D. magna life-history parameters. A decrease in glycogen, and the increase of haemoglobin, protein, and gluthione-S-transferase (GST) were observed. Furthermore, D. magna fed with bacterial single diets, presented worsen life history parameters and a decrease in the protein content. An induction of oxidative stress response (increased catalase and GST), and a significant decrease in lipid peroxidation and an accumulation of glycogen and carotenoids were observed. Overall, an increase in the amount of R. rubra provided to D. magna, from 0.2 AU to 0.4 AU, negatively impacted daphnid performance. No significant effects on Daphnia longevity (a 110-day assay) were observed among the three diets tested. However, a significant survival percentage and fertility (cumulative offspring is more than twice) was observed when D. magna was fed with the mixed diet. Conclusions: Results demonstrated that different diets provided a nutritional diversified food to the daphnids that induced differences in D. magna performance. The mixed diets proved to be beneficial (with increase in offspring) on D. magna performance, independently of the bacterial concentration tested. When in single diet, bacterial concentration is not nutritionally sufficient to raise D. magna even when in increased concentration.

Improvement of nutritional quality of live feed for aquaculture: An overview

et al. 2019

In hatcheries, the adequate supply of live feed has a vital role in feeding fish larvae, fry and fingerlings. Furthermore, the enhancement of the nutritional quality of live feeds is well‐developed techniques in aquaculture. Essential fatty acids (EFA) such as docosahexaenoic acid (DHA; C22:6 n−3), eicosapentaenoic acid (EPA; 20:5(n−3) and arachidonic acid (ARA; 20:4(n−6) and amino acids are an essential source of proteins for larval rearing of fish. However, the common practised live feeds used for the primary feeding such as rotifers and Artemia are naturally deficient in essential nutrient components. Hence, the improvement of the nutritional quality of live feeds with different oil emulsions and commercial diets, and manipulation of the feed are necessary for fish production. The production protocols of copepods, Moina and fairy shrimps as live feed are still underdeveloped in hatcheries. The different lipid sources using for the enrichment of Artemia and rotifers are not effective on other live feeds, especially copepods and cladocerans (Moina, Daphnia) and fairy shrimps. This review focuses on the importance of live feeds by the techniques of feed enhancement or enrichment of zooplankton by direct incorporation of nutrients for feeding of early stages of fish.
