“…The reported cost for a million of rotifers in this study was higher than those published by Bentley et al, (2008)($ 0.009) and Suantika et al, (2003) ($ 0.048), however, it was lower than Alvarez- Lajonchere and Álvarez et.al, (2013) at a cost of $ 1.65 in batch cultures. Oxygen is used by many authors as a resource to support the stability of rotifer cultures (Kostopoulou et al, 2006;Sayegh et al, 2007;Papakostas et al, 2007;Kobayashi et al ., 2008;Larsen et al 2008;Yin and Zhao, 2008;Cavalin and Weirich, 2009;Mahmoudzadeh et a.l, 2009;Qi et al, 2009), however, in the Pacific Marine Park adding oxygen posed no technical difference (ANOVA p> 0.05) compared to control culture due to several factors; the first is related to the fact that dissolved oxygen was controlled only during the day (it was not mechanized and there were workers who labored night shift) which did not allow a good control of this variable.…”

“…In terms of population parameters (Table 1), both growth rates are considered typical within the stated range for B. plicatilis in batch cultures (Suantika et al, 2003, Tinh et al, 2006. The doubling times of both systems match the reported (2 to 3.3 day -1 ) range by Vallejo et al, (1993) in his study of B. plicatilis.…”

“…Population yields of both crops are considered high compared to that reported by Abu-Rezq and James (2005) of 12.130+1,89 rot • l -1 • day -1 and that of Cisneros (2011) ranging from 1.330+0,33 a 13.580+0,02 rot • l -1 • day -1 . The yields of rotifers improve the more HUFA's and proteins their feeds contain Cisneros, 2011), adding to the success of using microalgae on such cultures (Suantika et al, 2003, Aragão et al, 2004, Benetti et al, 2008, Ferreira et al, 2008.…”

“…This has encouraged to research on the conditions that optimize the growth of populations of this organism (Kostopoulou et al, 2006;Sayegh et al, 2007;Papakostas et al, 2007;Kobayashi et al, 2008;Larsen et al, 2008;Yin and Zhao, 2008;Cavalin and Weirich, 2009;Mahmoudzadeh et al, 2009;Qi et al, 2009), specifically, may studies related to the addition of pure oxygen as support for rotifer cultures (Yoshimura et al, 1996;Dhert et al, 2001;Yoshimura et al, 2003), however, is necessary to evaluate the economic conditions as well as staff availability and infrastructure before deciding the technique with which to work, as noted by Suantika et al (2003) in their study on rotifers production progress.…”

Technical and economic feasibility of adding pure oxygen for rotifer production (Brachionus plicatilis) spotted snapper (Lutjanus guttatus) larvae feeding. AbstractA study to technically and economically evaluate the addition of pure oxygen in a culture of rotifers for feeding marine fish in the Pacific Marine Park, Puntarenas, Costa Rica was performed. The results showed no significant differences (ANOVA P> 0.05) between the cultivation with addition of oxygen treatment and control, regarding the instantaneous growth rate, crop yield, doubling time, rotifers length and maximum densities reached. Concerning the economic analysis, control culture was 53% less expensive compared to the addition of oxygen system.

ResumenSe realizó un estudio de factibilidad técnica y económica sobre la adición de oxígeno en la producción intensiva de rotíferos para alimentar peces marinos en el Parque Marino de Puntarenas Costa Rica. Los resultados mostraron que no existieron diferencias significativas (p>0,05) en cuanto a la tasa instantánea de crecimiento, rendimiento del cultivo, tiempo de duplicación, longitud de los rotíferos y máximas densidades alcanzadas. Con respecto al análisis económico el sistema sin oxígeno es 53% menos costoso que el sistema con adición de oxígeno.

“…Inland hatcheries in Thailand typically must import brine (150-200% salinity) at considerable expense from salt farms located in coastal areas. Effective reuse of this seawater is therefore desirable 8,11 . These www.scienceasia.org needs generated considerable interest in development of closed-recirculation systems for larviculture food production as an alternative to open, batch culture systems 5,[12][13][14] .…”

ABSTRACT:We have designed, built and operated a closed-recirculating, continuous culture system to produce microalgae and rotifers in seawater (25% salinity) for larval fish culture. The system opens a new perspective in terms of automated production of rotifers without labour cost. Rotifers can be easily harvested daily by a conical harvest net and there is no routine maintenance work. This new, automated system has three components: a microalga culture, a rotifer culture and storage with harvest, and a water treatment and re-use component. After treatment using mechanical filtration, biofiltration, UV sterilization, ozonation, and protein skimmers, water is re-used, thus nearly eliminating the need for seawater imports to the system. Our trial demonstrated that this culture system is capable of producing sustained and acceptable levels of rotifer production for at least 28 days. Microalga densities and yields were quite stable, while rotifer yield varied more during our 28 day culture period. Nitrogenous waste compounds were stable and well within acceptable levels, although nitrate and phosphate concentrations increased throughout the culture period, but did not negatively impact on rotifer production.

Intrinsic rates of population increase (r) were evaluated as a measure of population dynamics of four strains of Brachionus plicatilis and two strains of B. urceolaris from Iran in response to different salinities and feeding algae. Each rotifer strain was cultured at four salinities: 5, 20, 25 and 30‰ and fed with two microalgal species: Chlorella vulgaris and Nannochloropsis oculata. Salinity of 5‰ was critical for all the examined strains, at which r was at minimum and was different from the other salinities (P < 0.05). For B. plicatilis strains, the maximum r was observed in those fed on Chlorella at salinities of 10 and 30‰ (64 ± 0.01 day −1). While, in B. urceolaris, maximum r was for Nannochloropsis fed rotifers at salinity of 20‰ (0.69 ± 0.01 day −1). Maximum final population density (FD) was obtained for a strain of B. urceolaris fed on Nannochloropsis at 20‰ (329.3 ± 10.9 ind.mL −1). FD was relatively lower in B. plicatilis strains among all examined salinities. ANOVA showed the significant effect of salinity and rotifer strain, and algae × rotifer strain on both r and FD, and salinity × rotifer × algae on FD (P < 0.05). IntroductionRotifers are considered as ideal model organisms for various kinds of biological laboratory studies including population dynamics (YOSHINAGA et al., 1999;SARMA, 2006;SNELL and DESROSIERS, 2008). They have also become a valuable and, in many cases, indispensable food organism for first feeding of a large variety of cultured marine finfish and crustacean larvae (DOUILLET, 2000).Success in rotifer culture seems, to a great extent, to be dependent on providing adequate information on the life history characteristics and environmental preferences of each biotype. An increasing number of studies have been carried out on the effects of salinity, temperature and the type and concentration of food on the demographic traits and population growth of rotifers (CABRERA et al., 1993;OLTRA and TODOLI, 1997;FIELDER et al., 2000;SARMA and NANDINI, 2002;ATHIBAI and SANOAMUANG, 2008). These studies were accomplished using several rotifer species (XI et al., 2001;SUCHAR and CHIGBU, 2006;WULLUR et al., 2009
