“…Paracyclopina nana is one of the planktonic brackish water cyclopoid copepods with a high tolerance to salinity and temperature ranges (Lee et al, 2006). This kind of copepod species is an important food source for many developing juvenile fish larvae and crustaceans (Sun & Fleeger, 1995;Pinto et al, 2001).…”

As a special reference of the nuclear cistron rDNA of cyclopoid copepods, we obtained the entire DNA sequence of a single rDNA repeat unit from Paracyclopina nana (Cyclopoida: Cyclopettidae). The genomic organization of P. nana rDNA (7,974 bp, 51.7% of GC) was observed to be 18S-ITS1-5.8S-ITS2-28S-IGS in order. Comparative analyses of the rDNA between P. nana and other copepods showed that the intergenic spacer (IGS) was highly informative and divergent, while other coding regions are relatively conserved. We detected eleven poly(T) tracts in the IGS, demonstrating the high AT content in this region. In addition, many sub-repeat sequence patterns (e.g., AG, AT, GC, CCG, TC) such as microsatellites were identified from the rDNA IGS of P. nana. In this article, we show the first complete sequence of rDNA from the order Cyclopoida, providing a better understanding of molecular characteristics in molecular taxonomy.

“…Copepods are the predominant prey item for a vast majority of wild marine fish larvae (Hunter 1981;Leis 1991;Østergaard et al 2005;Samprey et al 2007). Furthermore, copepods contain the appropriate HUFA composition required for the growth and development of larval marine fish (Sargent et al 1997;Drillet et al 2006a;van der Meeren et al 2008) and can be manipulated through the algae they are fed (Stottrup et al 1999; Lee et al 2006). Advances in copepod production have occurred and nauplii have been successfully used as a live feed (Stottrup 2003;Lee et al 2005).…”

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

Mediterranean mariculture uses imported strains of marine phytoplankton, raising questions of ecological risk and ability to adapt to local conditions for mass culture outdoors. In this context, we report here on the mass-culture potential and chemical composition of six strains of Prasinophyceae (five strains of Tetraselmis sp. and one Pyramimonas sp.) isolated from a Greek coastal lagoon. Proximate composition had a pattern of 10-20% ash, 35-65% protein, 6-10% lipids, and 25-45% other organics including carbohydrates. The amino acid profiles were typical for the marine representatives of the class. All strains had a high PUFA content with dominant the ω3 fraction in four of them. The fatty acid profiles indicated a Tetraselmis strain with high EPA (14%) and a Pyramimonas strain with high DHA (6%). These strains might be a good alternative for the common commercial strains used in Mediterranean aquaculture.
