“…We successfully used these microalgae to culture P. similis. It has been reported that some species of rotifers including Platyias quadricornis (Enriquez-Garcia et al, 2003), Synchaeta cecilia (Egloff, 1988) and Synchaeta cecilia valentina (Oltra et al, 2000) are difficult to grow using N. oculata or C. vulgaris. Our result further shows that the effect of the two microalgae densities on population growth of P. similis was stronger at salinity 2 ppt than at 25 ppt.…”

The body length and width of Proales similis (mean±SD; 83±11 μm and 40±6 μm, respectively) is 38.1% smaller and 60.3% narrower than that of Brachionus rotundiformis.Due to its small size, P. similis has potential for rearing marine fish larvae which require first food smaller than B. rotundiformis. We examined the feasibility of using P. similis as live food by analyzing its life history, population growth and feeding incidence by fish larvae. P. similis produced first offspring on 2.5-2.8 days after hatch. Females produced 4.3-7.8 offspring during their 2.9-3.4 day reproductive period. P. similis grew well at temperatures 25 to 35 0 C (density = 250 to 1030 ind./ml; r = 0.68 to 0.81 day -1 ) and at salinities 2 to 15 ppt (density = 360 to 500 ind./ml; r = 0.73 to 0.78 day -1 ). Population density of P. similis was higher than B. rotundiformis after 8 days of culture period with either N. oculata and C. vulgaris as food. In mass culture, population density of P. similis increased from 25 to 2,400 ind./ml (r = 0.42 day -1 ) after 11 days. Results from feeding experiments confirm that P. similis is consumed by seven-band grouper (Epinephelus septemfasciatus) larvae. The larvae demonstrated the highest feeding rate at 20 ind./ml of P.similis.

“…For example, since the first use of baker's yeast as food, several attempts have been made to combine it with green algae for both freshwater and saline rotifer species [30,31]. Numerous studies have been also made using two more types of marine algal species on the population growth of marine or saline water rotifer species such as Brachionus plicatilis and Synchaeta cecilia [32,33]. Arévalo-Stevenson et al [34] have also shown that B. calyciflorus shows higher growth rates on wastes from the tortilla industry with Chlorella than on the latter alone.…”

Correspondence: J. Flores-BurgosIn the present work we tested the effect of Chlorella vulgaris and Scenedesmus acutus in different proportions on the population growth of Brachionus calyciflorus, Brachionus patulus, Ceriodaphnia dubia, and Moina macrocopa. In general, both rotifer species grew well on either type of algae. Regardless of algal mixture, B. calyciflorus had a shorter initial phase, while B. patulus needed more than a week to begin the exponential phase of growth. Both the rotifer species showed consistently better population growth with Chlorella than on Scenedesmus, or the mixture. At any given algal combination, B. patulus had higher peak values than B. calyciflorus.The rate of population increase (r) for both the rotifers varied from 0.18 to 0.48 d -1 depending on the algal type and combination. Regardless of algal type and combination, B. calyciflorus had a much higher value of r than B. patulus. Both C. dubia and M. macrocopa grew on the algal types, whether offered separately or in mixture. Regardless of the treatment type, C. dubia needed a longer period (about 2 weeks) than M. macrocopa to reach peak abundances. Thus, our study did not support the view that Scenedesmus is consistently superior to Chlorella as a basic diet to the tested species of zooplankton.

“…In aquaculture, rotifers are used as food for fish larvae because of their high essential fatty acid content (e.g., eicosapentenoic [20 : 5n-3] and docosahexenoic [22 : 6n-3] acids; Oltra et al 2000). The Hudson River is a specific case that gives us a window of opportunity to reveal this same trophic dependence of mussels on mesozooplankton.…”

We tested the hypothesis that rotifer species in the micro‐ and mesozooplankton are a potential food source for zebra mussels. We labeled phytoplankton with 14C, fed them to two species of rotifers (140–210 µm length) that were previously found abundantly in the Hudson River and had declined following a zebra mussel invasion, and estimated the assimilation of carbon. Assimilation efficiencies were found to be ~37.47–54.0%. Combined with our feeding experiments, the data on rotifer densities before and after the invasion allowed us to calculate the energy budgets for zebra mussels. Before zebra mussels dominated the Hudson River in 1992, the absorption of energy from rotifers was about two to three times higher than that necessary to maintain its routine metabolic rate and contributed about 0.349–0.662 J h−1 to mussel growth and reproduction, conferring a positive scope for growth. Since the zebra mussels became abundant in the Hudson River, assimilation of rotifers is still sufficient to explain ~16.4–23.1% of the mussels' routine metabolic rate. Therefore, rotifers play a conceivably large role in the energy budget of zebra mussels, whether at high rotifer concentrations (before the invasion) or at low rotifer concentrations (after the invasion). This is the first quantitative evidence for a trophic link between benthic bivalve mollusks and larger micro‐ and mesozooplankton that might extend to marine systems where bivalves can derive nutrition from microzooplankton, including planktonic invertebrate larvae. Combined with other recent results, this study documents a benthos‐zooplankton trophic loop, demonstrating potentially strong top‐down control by dense bivalves on aquatic systems.
