“…Mean lifespan of B. manjavacas ranged from 10.3 – 15 days when fed equal quantities of one of four different species of algae [ 16 ]. When fed ad libitum on one of five different algae species, Brachionus koreanus median lifespan ranged from 6 – 10 days and maximum lifespan ranged 6.5 – 11 days, differences of 40% [ 39 ]. These different diets led to significant changes in fatty acid composition and in expression of lipid metabolism genes in the rotifers, though the role of these shifts in directly determining lifespan is unclear [ 39 ].…”

As expected, when food is not limiting there was no correlation or trade-off between reproduction and lifespan [ 39, 40 ]. Interestingly, an investigation of B. calyciflorus and B. patulus fed two different algae singly or in combination demonstrated that the difference in lifespan and reproduction was as great between the two rotifer species on the same diet as for the same species fed different diets [ 40 ], emphasizing the significant variability in lifespan and response to dietary changes among species, even when very closely related.…”

Because every species has unique attributes relevant to understanding specific aspects of aging, using a diversity of study systems and a comparative biology approach for aging research has the potential to lead to novel discoveries applicable to human health. Monogonont rotifers, a standard model for studies of aquatic ecology, evolutionary biology, and ecotoxicology, have also been used to study lifespan and healthspan for nearly a century. However, because much of this work has been published in the ecology and evolutionary biology literature, it may not be known to the biomedical research community. In this review, we provide an overview of Brachionus rotifers as a model to investigate nutritional and metabolic regulators of aging, with a focus on recent studies of dietary and metabolic pathway manipulation. Rotifers are microscopic, aquatic invertebrates with many advantages as a system for studying aging, including a two-week lifespan, easy laboratory culture, direct development without a larval stage, sexual and asexual reproduction, easy delivery of pharmaceuticals in liquid culture, and transparency allowing imaging of cellular morphology and processes. Rotifers have greater gene homology with humans than do established invertebrate models for aging, and thus rotifers may be used to investigate novel genetic mechanisms relevant to human lifespan and healthspan. The research on caloric restriction; dietary, pharmaceutical, and genetic interventions; and transcriptomics of aging using rotifers provide insights into the metabolic regulators of lifespan and health and suggest future directions for aging research. Capitalizing on the unique biology of Brachionus rotifers, referencing the vast existing literature about the influence of diet and drugs on rotifer lifespan and health, continuing the development of genetic tools for rotifers, and growing the rotifer research community will lead to new discoveries a better understanding of the biology of aging.

“…Alternatively, long‐term enrichment procedures for rotifers were carried out with n−3 HUFA emulsified lipids and baker's yeast (Eryalçın, , ; Olsen et al, ). Due to their superior nutritional quality microalgae and other enrichment diets regularly used for enrichment purpose of live feeds for feeding of larval stages of fishes (Aragão, Conceição, Dinis, & Fyhn, ; Fehér et al, ; Koiso, Yoshikawa, Kuwada, & Hagiwara, ; Lee et al, ; Mæhre et al, ; Srivastava, Hamre, Stoss, Chakrabarti, & Tonheim, ), provided that the culture technique ensures a sufficient nutritional quality of the microalgal biomass (Ferreira, Coutinho, Seixas, Fábregas, & Otero, ; Ferreira, Maseda, Fábregas, & Otero, ). Some microalgae such as Nannochloropsis oculata and Isochrysis galbana contain high amount of essential fatty acids, for example EPA; DHA has made them excellent live food diets for boosting the fatty acid content of the rotifers.…”

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.
