“…Protein content, for example, can reach more than 50% in some genera (e.g. Daphnia , Moina and Cyclops ), although rotifers tend to exhibit lower values, between 25 and 50% of dry weight (Aragao et al., ; Conceicao et al., ; Jeeja et al., ; Yin et al., ). In general, the proportion of essential amino acids tends to be slightly above 50% of total amino acids for cladocerans and copepods (Jeffries, ; Kibria et al., , ; Mitra et al., ), but slightly below 50% for the most studied rotifer B. plicatilis (Srivastava et al., ; Yin et al., ).…”

Summary This review paper aims to offer a current view on the function of zooplankton as food for common carp, as traditionally its role has been underestimated compared with benthic invertebrates or supplementary feeding. We prove the importance of zooplankton organisms in the life cycle of common carp in fishponds. As in other fish species, carp larvae feed mainly on zooplankton, starting with small organisms (rotifers) and as they grow then shifting to larger organisms, e.g. copepods and cladocerans. As adults they are commonly benthic feeders, concentrating principally on zoobenthos (mainly chironomid larvae); however, zooplankton is also an important part of the diet, depending on food availability and spatial and temporal variation. Zooplankton is high in protein (above 50% of dry matter for some groups) and lipids (approximately 10% of dry matter with a significant proportion of unsaturated fatty acids). Natural food therefore may provide a high nutritional content, compared to other diets. Appropriate management strategies in fishponds can potentially increase the production of zooplankton, e.g. monitoring zooplankton levels and stocking fish at the appropriate moment, control of environmental variables favouring zooplankton development, and utilizing sustainable fish stocking densities.

“…Rotifers have approx. 20% lipids by dry weight, although they are generally poor in HUFAs (Yin et al., ). Copepods have moderate lipid levels (predominantly unsaturated DHA), while cladocerans have a higher proportion of monounsaturated fatty acids and EPA (Persson and Vrede, ; Guo et al., ; Smyntek et al., ; Mraz et al., ).…”

RESUMEN. La producción de microalgas vivas para cultivar rotíferos constituye uno de los mayores costos de operación en la larvicultura de peces, por lo que se están desarrollando sustitutos comerciales de microalgas para la alimentación y producción de rotíferos. Se desconoce el efecto que tienen las formulaciones comerciales sobre la dinámica poblacional de rotíferos nativos del noroeste de México y en este estudio se evaluó el efecto de cuatro dietas comerciales (Espirulina, RotiMac®, Nanno 3600®, RotiGrow-Plus®) y la microalga viva Nannochloropsis sp., sobre el crecimiento poblacional y fecundidad del rotífero Brachionus ibericus (GenBank KJ949043), aislado de una granja de camarón blanco (Litopenaeus vannamei). Se realizaron cinco réplicas por tratamiento alimenticio utilizando recipientes con volumen de 12 L de agua, con temperatura de 29 ± 1°C y salinidad de 35 ± 1, respectivamente. Los resultados mostraron que durante los periodos experimentales, las dietas probadas resultaron adecuadas para alimentar a B. ibericus, con tasas de crecimiento, tiempos de duplicación, densidades máximas y fecundidades que fluctuaron entre 0.20 a 0.27 rotíferos día , respectivamente. Las diferencias entre tratamientos fueron significativas (P < 0.05); los menores tiempos de duplicación y las mayores tasas de crecimiento, fecundidad y densidad poblacional fueron obtenidas con RotiGrow-Plus ® , pero el tiempo de duplicación y la tasa de crecimiento con RotiGrow-Plus ® no fueron significativamente diferentes (P > 0.05) a las obtenidas con Nanno 3600 ® .Palabras clave: Brachionus ibericus, Nannochloropsis, rotíferos, dinámica poblacional, dietas comerciales. Population dynamics of rotifer Brachionus ibericus isolated from shrimp ponds, fed with different dietsABSTRACT. The production of live microalgae to cultivate rotifers is one of the largest operating costs in fish hatcheries. Commercial substitutes of microalgae are being developed to feed and produce rotifers. The effect of commercial formulations on the population dynamics of native rotifers of northwestern Mexico is unknown, so in this study the effect of four commercial diets (Spirulina, RotiMac®, Nanno 3600®, RotiGrow-Plus®) was evaluated as well as the live macroalgae Nannochloropsis sp., on the population growth and fecundity of the rotifer Brachionus ibericus (GenBank KJ949043), isolated from a white shrimp farm (Litopenaeus vannamei). Five replicates per dietary treatment were performed using 12 L containers with temperature of 29 ± 1°C and salinity of 35 ± 1 respectively. The results showed that during the experimental period, the diets tested were suitable to feed B. ibericus, with mean growth rates, duplication times, maximum densities and fecundities that ranged from 0.20 to 0.27 rotifers day-1, 2.60 to 3.42 days, 0.16 to 0.39 eggs per female and 215.4 to 357.0 rotifers mL -1 , respectively. Differences between treatments were significant (P < 0.05); lower doubling times and higher growth rates, fecundities and population densities were obtained with RotiGrow-P...

“…As a filter feeder, the Manila clam mainly feeds on benthic diatom assemblages and abundant organic matter including macroalgal detritus, as long as the particle size is suitable for ingestion (Wang & Wang, ). Macroalgae, consisting of red, brown and green algae, are often identified as seaweeds, which are typically attached to the strata, for example rocks, coral and silica sand (Yin, Min, Lin, & Chen, ). As the primary productivity of off‐shores in temperate seas, seaweeds are the most essential marine plants and possess vital ecological function and economical value.…”

“…Detritus production from macroalgae, such as Laminaria japonica (Uchida & Numaguchi, ), Laminaria saccharina (Camacho, Salinas, Fuertes, & Delgado, ), Ulva pertusa ( Ulva , Uchida & Numaguchi, ; Yin et al, ), Undaria pinnatifida ( Undaria , Yin et al, ) and Chondrus ocellatus ( Chondrus , Yin et al, ), has been successfully achieved; the feasibility of utilizing macroalgal detritus as partial substitutes for microalgae has been evaluated in several species of filter‐feeding bivalves, including the clams R. decussatus and R. philippinarum , together with tropical oyster ( Crassostrea belcheri ) (Camacho, Salinas, Delgado, & Fuertes, ; Camacho et al, ; Tanyaros & Chuseingjaw, ; Uchida & Murata, ; Uchida & Numaguchi, ). However, the potential of macroalgal detritus as replacement for microalgae in culture of juvenile R. philippinarum remains unknown.…”

Sufficient high‐quality microalgae are required for indoor nursery of juvenile Ruditapes philippinarum. However, culturing numerous microalgae to support clam feeding is a heavy burden on many hatcheries. The effects of detritus from the macroalgae Ulva pertusa, Chondrus ocellatus and Undaria pinnatifida on the growth, amino acid content and fatty acid profile of R. philippinarum were assessed as potential substitute diets. The green microalga Tetraselmis cordiformis served as comparative diet. Results revealed that the clams ingesting distinct diets presented no significant differences in growth of soft tissues, but the nutritional component of these clams differed dramatically. The clams fed with Undaria + Tetraselmis had the highest content of essential amino acids and proteins. In addition, the clams fed with single macroalgal diets and mixed macroalgal detritus and Tetraselmis showed significantly higher or statistically equal levels in n‐3/n‐6 ratio and docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA) ratio with respect to Tetraselmis diets. The relative percentages of EPA and DHA in clams fed with Undaria were 28% and 63% higher than those fed with Tetraselmis, and the arachidonic acid abundances in clams ingesting Undaria + Tetraselmis and Tetraselmis were significantly higher than those in clams ingesting other diets. Together, the diets containing single Undaria or mixed Undaria + Tetraselmis produced Manila clams with nutritional advantages in terms of essential amino acids and polyunsaturated fatty acids. Thus, the detritus of macroalgae, especially Undaria, is an appropriate substitute diet, at least partially, for culture of nutrition‐improved R. philippinarum.
