“…Sample collection and morphometric analysis.-Morphometric analysis of fish larvae was adapted from techniques described in Cavalin and Weirich (2009). On 0 DPH, 60 yolk sac larvae were randomly selected from the incubation tank for morphometric analysis.…”

“…In trial 3, four diets, each replicated seven times, were examined: the SRD; an all copepod diet; a 3-d diet; and a mixed diet. The SRD was adapted from pompano larviculture protocols established by USDA-ARS (Weirich and Riley 2005;Cavalin and Weirich 2009). Beginning on 2 DPH, larvae were fed diets consisting of enriched S-strain rotifers Brachionus plicatilis having a body width of 117.5 ± 19.8 µm (Cavalin and Weirich 2009), P. pelagicus nauplii with a body width of 93.2 ± 13.7 µm (Cassiano 2009), or both.…”

The Florida pompano Trachinotus carolinus is a highly prized marine fish species, the larviculture of which currently includes the feeding of live rotifers and nauplii of brine shrimp Artemia spp. However, no previous studies have evaluated the feeding of copepod nauplii. In this study, the growth and survival of Florida pompano larvae fed nauplii of the calanoid copepod Pseudodiaptomus pelagicus were compared with those of larvae fed the standard reference diet of enriched rotifers Brachionus plicatilis. Experiments were conducted during the first 7–9 d posthatch (DPH), a period preceding the provision of Artemia nauplii. Treatments included feeding only copepod nauplii during the first day, the first three days, and on all days, as well as copepod nauplii mixed with rotifers during the entire experiment. In addition, the dietary effects on larval fatty acid composition were examined. Feeding copepod nauplii at a density of 2.0–3.5 nauplii/mL during the first day or the first three days of feeding had advantages over feeding only rotifers. However, after approximately 3 DPH, increased quantities of nauplii were needed to provide sufficient nutrients for growth. This was demonstrated in larvae fed copepod nauplii for the entire trial, for which survival was significantly higher than for the other treatments but for which growth was significantly reduced. Larvae fed a mixture of rotifers and nauplii for the entire trial had survival similar to that of larvae fed only rotifers (∼40%); however, growth was greater in larvae fed the mixed diet, suggesting that there is a nutritional advantage to including copepods in the diet. Fatty acid analyses revealed that increased levels of docosahexaenoic acid were associated with larvae fed copepods, which probably contributed to the observed higher survival and growth. These results indicate that there are multiple benefits to feeding copepods to Florida pompano larvae.Received June 6, 2010; accepted August 10, 2010

“…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. According to Alvarez-Lajonchere and Álvarez et.al, (2013) results in rotifer cultures depend on the correct technology developed in the laboratory.…”

“…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. Palabras claveBrachionus plicatilis, Lutjanus guttatus, crecimiento, fecundidad, rendimiento, rotíferos. 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.
