“…The adoption of a long period of co-feeding seemed to have delayed postlarval adaptation to an inert diet, leading to a decrease in their condition and making weaning more difficult. A long period of co-feeding seems to be advantageous for larval stages (Person- Le-Ruyet et al, 1993;Cañavate and Fernández-Díaz, 1999;Baskerville-Bridges and Kling, 2000), but appears not to be the most suitable for Senegalese sole postlarvae.…”

The objective of this study was to evaluate the weaning success of Senegalese sole, Solea senegalensis, postlarvae when cofed a compound diet, by means of the analysis of growth parameters (relative growth rate [RGR] and condition factor [K]), survival, protein and lipid content. Total ammonia in the rearing water was also measured. The experiment lasted for 46 days (36 to 82 days posthatching). One group was fed only with enriched Artemia sp. metanauplii (Artemia treatment), whereas in another group, the Artemia sp. metanauplii were gradually replaced by the International Council for the Exploration of the Sea (ICES) diet over a period of 39 days (ICES treatment). Postlarvae were sampled on rearing days 0, 9, 23, 30, 39 and 46 for growth and biochemical analysis. Water was sampled on rearing day 30 during a 24-h cycle in both treatments. Postlarvae from the ICES treatment were weaned, though by the end of the experiment the Artemia treatment exhibited significantly higher values for growth, RGR, K and survival rates (P < 0.05). No significant differences were observed concerning total lipid content. Protein content was significantly higher for the Artemia treatment after 46 days of rearing (P < 0.05). The total ammonia nitrogen concentration in the water increased after each meal and remained below a harmless level for postlarvae.

“…Co-feeding of fish has been shown to enhance larval performance (Kanazawa et al, 1989;Cañavate and Fernández-Díaz, 1999;Baskerville-Bridges and Kling, 2000), and to allow weaning in a shorter time (Person-Le-Ruyet et al, 1993).…”

“…This situation indicates that although weaning can be achieved at metamorphosis and/or formation of functional stomach, earlier introduction of MD can result relatively lower growth performance and enzymatic activities as described for sea bass Lates calcarifer, (Walford and Lam, 1993), Japanese flounder Paralichthyis olivaceus (Kanazawa et al, 1989), Atlantic cod Gadus morhua (Baskerville-Bridges and Kling, 2000) and haddock Melanogrammus aeglefinus (Hamlin and Kling, 2001).…”

“…Recent studies have more particularly focused on the functional changes in the digestive tract during larval development by studying the onset and the variation of pancreatic and intestinal digestive enzymes and the response of these enzymes to diet concentration and composition. In this respect, early weaning by MD in marine fish larvae is remarkable and is accepted as a new physical and financial approach aimed at substituting live food production (Baskerville-Bridges and Kling, 2000;Hamlin and Kling, 2001;Alves et al, 2005;Curnow et al, 2006). Furthermore, substitution of live food by formulated diets and co-feeding of sea bass larvae is closely related with digestive enzyme activities.…”

In this study, effects of early weaning of sea bass (D. labrax) by microparticulate food on larval development and digestive enzyme activities, acid protease and alkaline protease were investigated until day 40. Larval rearing was conducted in closed sea water systems. Experiments were triplicated on 3 different weaning protocol that introduced on day 15 (MD15), day 20 (MD20) and day 25 (MD25) and also no microparticulate diet (MD) distributed in the control group. At the end of the experiment at 40-day, larval growth was calculated and the best values were obtained from MD25. Statistical differences among groups were not important (P>0.05) whereas MD15 was found different than the other groups (P<0.05). Also, survival rates were calculated as 3.6%, 14.7%, 43.6%, and 34.1% for the experimental groups, respectively. MD15 and MD20 groups were found different than the other groups (P<0.05). Nevertheless, activity of alkaline protease was detected synchronously by mouth opening and exogenous feeding and also increased by larval development. According to histological analysis, pancreas was observed by mouth opening and similarly developed with increasing of larval age. Alkaline protease activity changed by nutritional composition of feed and especially shifting of feed affected the enzymatic activity. There was no differences among the experimental groups (P>0.05) while control group was found statistically different (P<0.05). According to histological analysis, gastric glands and formation of functional stomach were observed on day 24-25 in all experimental groups. Acid protease activity firstly detected at 25 DAH. Control group was found different than the other groups (P<0.05). Finally, in terms of both growth parameters and survival rate and digestive enzyme activities it is clearly concluded that MD supplementation could be started after 25 DAH in D. labrax larviculture.Keywords: Sea bass, microparticulate feed, larval development, early weaning, digestive enzymes. Levrek (D. labrax, L.) Larvalarında Erken Dönem Mikropartikül Yem Girişi: Larval Gelişim ve Sindirim Enzimleri Aktivitesine Olan Etkisi ÖzetBu çalışmada; levrek (D. labrax) balığının larva kültüründe erken dönemde mikro partikül yemler kullanılmasının, larvaların yaşama ve büyüme oranları ile sindirim enzimlerinden asit proteaz ve alkalin proteaz aktivitesi üzerine olan etkileri 40. güne kadar incelenmiştir. Larval yetiştiricilik kapalı devre sistem kullanılarak gerçekleştirilmiştir. 3 tekrarlı olarak yürütülen denemelede larvalara 15. gün (MD15), 20.gün (MD20) ve 25. gün (MD25) olmak üzere üç farklı dönemde mikro partikül yeme geçilmiş, kontrol grubundaki (K) larvalara herhangi bir yem girişi yapılmamıştır. Denemenin bittiği 40. gün sonunda, larvalara ait total boy ve ağırlık gelişimleri incelendiğinde en iyi değerler MD25 grubundan elde edilmiştir. Deneme grupları arasındaki fark önemsizken (P>0,05) MD15 grubu diğer gruplar ile arasında önemli farklılıklar bulunmuştur (P<0,05). Yaşama oranları ise gruplara göre sırasıyla %3,6, %14,7, %43,6 v...

“…Quang et al (2011) indican que durante la deshabituación temprana en larvas de la cobia (Rachycentron canadum), de menos de 25 días PE, estas no aceptan regularmente microdietas, considerando que esta especie presenta un estómago funcional entre los 12 y 20 días PE. Existe antecedentes donde la deshabituación al alimento vivo puede efectuarse anticipadamente, tal es el caso del uso de microdietas en Gadus morhua, donde la administración del alimento formulado comienza a los ocho días PE (Baskerville-Bridges & Kling, 2000). Juveniles de Graus nigra de 45 días PE evidencian una marcada sensibilidad al manejo, registrando mortalidades de hasta un 38% cuando los peces son trasladados entre estanques y durante los muestreos para los registros de LT y PT.…”
