“…Most marine fish larvae depend on live feed for the initial life stages. In marine hatcheries, the production of live prey is considered a somewhat unpredictable, expensive task with results of variable nutritional quality (Person‐Le Ruyet 1989; Callan et al 2003; Rao 2003; Carvalho et al 2006). Therefore, weaning fish larvae, as soon as possible, to artificial diets is a major goal in commercial operations.…”

Red porgy, Pagrus pagrus, is a candidate species for aquaculture diversification. The aim of this work was to assess whether an early supply of enriched Artemia (D1) or a direct step to dry diets (D3) would be advantageous weaning strategies for red porgy larvae, compared to a later supply of Artemia followed by dry diets (D2). Direct weaning to dry diet resulted in significantly lower growth, survival, pancreatic (trypsin and lipase), and intestinal (alkaline phosphatase) enzyme‐specific activity, with the exception of leucine‐alanine peptidase. The direct weaning strategy presented severe nutritional restrictions from early weaning stages with an associated delay of the maturation of digestive system. The two‐step strategy presented in D1 and D2 resulted in comparable results in most parameters, including survival. Weaning using enriched Artemia as an intermediate step is confirmed as the most adequate strategy for red porgy larvae. Digestive enzymes and selected fatty acids correlated well with performance responses to dietary regimes, thereby supporting the use of these parameters as sensitive and reliable indicators of red porgy nutritional or physiological status during larval stages.

“…Cofeeding with Artemia and microdiets have been found to be superior to feeding with Artemia or microdiet alone in barramundi species (Curnow et al 2006), sole species (Engrola et al 2007), and Atlantic cod species (Callan et al 2003; Fletcher et al 2007). We found that cofeeding yielded higher survival and larger postlarvae compared with feeding solely with microdiet in Experiment 1 but lower survival and growth compared with postlarvae fed solely with Artemia .…”

“…Historically, striped trumpeter postlarvae were reared using enriched Artemia until 100 d posthatch (dph). Earlier weaning onto microdiets can reduce the use of Artemia and possibly improve larval survival and growth and reduce the incidence of malformations by providing postlarvae with a better and more consistent supply of nutrients; particularly ascorbic acid (AA) (Callan et al 2003; Fletcher et al 2007; Kestemont et al 2007).…”

The striped trumpeter, Latris lineata, is a native fish being developed for aquaculture in Tasmania, Australia. Striped trumpeter have a long postlarval stage and rearing has been reliant on the long‐term use of Artemia. Two experiments were conducted to investigate weaning strategies. The first experiment used 52 d posthatch (dph) postlarvae previously reared on Artemia from 16 to 52 dph enriched with either low or high ascorbic acid. The treatments were Artemia, a microdiet, or cofeeding. The postlarvae were reared until 67 dph. The Artemia treatment yielded significantly higher mean survival, followed by cofeeding, and the microdiet. Feeding Artemia yielded significantly heavier postlarvae and the microdiet produced significantly smaller postlarvae. A second experiment used 41 dph postlarvae and investigated the effect of cofeeding duration prior to feeding with Artemia and microdiet as controls. Cofeeding periods of 5, 10, and 15 d were tested. Cofeeding for 5 d and microdiet feeding yielded significantly poorer survival compared with Artemia. Artemia feeding yielded significantly heavier postlarvae. In both experiments, the diets did not have a significant effect on jaw morphology. These experiments are the first to examine weaning strategies for striped trumpeter postlarvae and suggest cofeeding postlarvae from 40 dph and feeding microdiet exclusively at 50 dph.

“…Indeed, exhibits good growth during the larval period when fed on live prey (Vazquez et al, 1994;Dinis and Reis, 1995); the weaning, switch from live prey to compound diet feeding, induces poor growth and mortality (Dinis, 1992;Marin-Magan et al, 1995), weaning and metamorphosis which are accompanied by increased mortality rates (Rueda-Jasso et al, 2005). Standard feeding regimens during these periods represent a bottleneck for fish farmers due to the required administration to young larvae of live-feed usually characterized by: 1) variable availability and price fluctuations of Artemia cysts (Callan et al, 2003), which can reach 700% (Moretti et al, 2005); and 2) poor hygienic conditions and high levels of pathogenic bacteria (Olsen et al, 2000;Olafsen, 2001). Metamorphosis is a crucial developmental phase in flatfish species.…”

This study was conducted to evaluate the optimum salinity and temperature on growth and development of Solea aegyptiaca larvae and weaning feed type on growth of Solea aegyptiaca post-larvae. The first experiment was tested five different salinities (10, 15, 20, 25 and 30‰). The results found that, no significant difference in growth rate, but the best performance and survival rate of larvae was at salinity 20‰. The second experiment was tested eight different water temperature (16, 17, 18, 19, 20, 21, 22 and 23°C). The results showed that, the larvae under temperature 20 °C showed the highest growth rate, while the best survival rate was recorded at temperature 16 °C under experimental conditions. The growth rate for larvae has been increased gradually with increasing temperature until 20 °C then decreased, while survival rate was decreased gradually with increasing temperature. The third experiment was tested three different feed (Artemia (T 1 ), Artemia + artificial feed (T 2 ) and artificial feed (T 3 )) of Solea aegyptiaca post-larvae weaning. Results of growth performance parameters were highest with post-larvae fed on (T 1 ) compared to the other feeds (T 2 and T 3 ). Larvae fed on (T 1 and T 2 ) led to higher survival rate compared to fed on (T 3 ).
