“…Co-feeding could thus improve the nutritional status of larvae to avoid this big variation. Similar results were reported in barramundi (Lates calcarifer Bloch) (Curnow et al, 2006a), fat snook (Centropomus parallelus Poey1864) (Alves et al, 2006), Senegalese sole (Engrola et al, 2007) and Dover sole (Solea solea L.) (Rueda-Jasso et al, 2005).…”

“…A reduced survival on 25 dph was also reported for cobia larvae weaned onto a microdiet from 16 dph, compared to those fed live feed (unpublished data referred to in Faulk et al 2007a). Reduced growth and/or survival rate of early weaned fish larvae has also been reported for other species (Curnow et al 2006a;Engrola et al 2007;Civera-Cerecedo et al 2008).…”

Effects of early weaning strategies on growth, survival and digestive enzyme activities in cobia (Rachycentron canadum L.) larvae

et al. 2010

The effects of weaning strategies of cobia (Rachycentron canadum L.) larvae to commercial microdiets, either from rotifers or from Artemia, on growth, survival and enzymatic digestive capacity, were investigated. In the first experiment, cobia larvae were weaned from rotifers by co-feeding with a microdiet (Otohime) from 8, 13 or 20 days post-hatching (dph). The larvae in the control treatment were fed rotifers (2-12 dph), Artemia nauplii from 7 dph, and co-fed with the microdiet from 20 dph. In the second experiment, the larvae were weaned from Artemia, which was fed to the larvae from 7 dph, by co-feeding with a microdiet (NRD) from 8, 13 or 18 dph. The larvae in control treatment were fed rotifers, then Artemia to the end of the experiment (28 dph). Weaning of cobia larvae onto a microdiet directly from rotifers significantly reduced growth, survival and digestive capacity of the larvae and did not lead to larval acceptance of the microdiet, compared to those weaned from Artemia in the first experiment. Early weaning of cobia larvae onto NRD microdiet (on 8 or 13 dph) from Artemia in the second experiment also reduced growth, survival rate and gut maturation index, compared to those fed live feed. With available microdiets, weaning of cobia larvae could start from Artemia at around 18 dph in order to obtain comparable growth, survival and gut maturation to larvae fed live feed.

“…According to Cañavate and Fernández-Díaz (1999), long periods of Artemia feeding diminish weaning success, although the fact that larvae are unable to digest dry food efficiently before the stomach begins to change must be considered, since inadequate ingestion can retard or even disable the genetic sequence of intestinal maturation (Walford and Lam 1993;Cahu and Zambonino-Infante 2001). In fact, Curnow et al (2006) showed that the premature introduction of inert food inhibits the growth of barramundi Lates calcarifer (Bloch) larvae. High growth rates usually occur during the co-feeding phase (Segner and Witt 1990;Lee and Litvak 1996;Cañavate and Fernández-Díaz 1999).…”

Weaning of the wedge sole Dicologoglossa cuneata (Moreau): influence of initial size on survival and growth

et al. 2009

The weaning phase can be decisive in fish-culture viability. In this work, the relationship between the initial size and weaning success has been studied in wedge sole (Dicologoglossa cuneata). For each age (30, 50, and 70 days after hatching, DAH), two to three sizes were selected, and all were put on the same feeding schedule for 20 days. Each batch (three replicates) was sampled at 1, 10, and 20 days. Specific growth rate (SGR) and survival were compared at the end of the co-feeding period, after 10 days on dry feed only. The best results for survival and growth were found with the smallest larvae, and vice versa. The SGRs and survival rates recorded during the co-feeding period were higher (0.8-15.6 day -1 and 68.3-97.8%) than those from the dry-food phase (0.9-4.7 day -1 and 56.3-66.7%). Successful weaning (survival = 65% and SGR = 9.3 day -1 ) is possible with 30 DAH larvae (7.6-8.1 mm and 3.9-4.6 mg). In conclusion, the most effective weaning would be possible at 30 DAH, implying significant Artemia savings (25-50%).
