“…A quite similar developmental profile for lipolytic activity were reported in different cultured species such as, Solea senegalensis (Martínez et al, 1999), S. ocellatus (Lazo et al, 2000), D. sargus (Cara et al, 2003), P. erythrinus (Suzer et al, 2006b), and yellowtail kingfish, Seriola lalandi (Chen et al, 2006) larvae. Similar enzymatic profile in lipase activities were found in larvae of cultured species such as Solea senegalensis (Martínez et al, 1999), S. ocellatus (Lazo et al, 2000), D. sargus (Cara et al, 2003), P. erythrinus (Suzer et al, 2006b), , S. lalandi (Chen et al, 2006), P. pagrus (Suzer et al, 2007a), and D. puntazzo (Suzer et al, 2007b). In spite of Gisbert et al (2009) reported that lipase was detected at hatching and progressively increased with larval growth of D. dentex larvae, a contrast profile were noted after co-feeding period 30 DAH related with administration of microdiet.…”

Stage-specific ontogeny of main digestive enzymes in common dentex, Dentex dentex, were assayed during early life development according to notochord flexion studied from hatching to 45 days after hatching (DAH). The notochord was straight in yolk-sac larvae of D. dentex and preflexion stage was observed between 0 and 18 DAH as 2.75 and 6.27 mm at total length (TL). Then, flexion of the notochord was estimated between 19 and 30 DAH as 6.27 and 10.9 mm at TL. Important alterations in specific activities of all digestive enzymes measured during period of this study were mostly related with metamorphosis and co-feeding. Trypsin and chymotrypsin specific activities were firstly detected on day 3 and were related with mouth opening, whereas they slightly increased until 25 DAH respectively. Pepsin was firstly detected on day 28 and related with stomach formation and a sharp increase was observed until 30 DAH. Both amylase and lipase were measured on day 2 and 4, respectively and they also sharply increased during the first week of life. Additionally, except pepsin, most of the digestive enzyme activities were firstly secreted in the preflexion stage and also gastric secretion started and functional development digestive system were occurred in in flexion and postflexion stages, respectively.Keywords: Digestive enzymes, stage-specific ontogeny, larval development, Dentex dentex, common dentex. Kültürü Yapılan Sinarit (Dentex dentex) Larvalarında Sindirim Enzimlerinin Dönemsel Gelişimi ÖzetBu çalışmada, sinarit (Dentex dentex) larvalarında açılımdan 45. güne kadar geçen erken dönem boyunca önemli sindirim enzimlerinin dönemsel ontogenileri notokorda bükülmesine göre incelenmiştir. Besin keseli sinarit larvalarında notokorda düz yapıda gözlenmiş ve bükülme öncesi dönem 0 ile 18. günler arasında 2,75 ile 6,27 mm total boy uzunlukları arasında izlenmiştir. Ardından, notokordanın bükülmesi ise 19 ile 30. günler arasında 6,27 ile 10,9 mm total boy uzunlukları arasında tespit edilmiştir. Çalışma boyunca izlenen sindirim enzimleri aktivitelerindeki önemli değişimlerin çoğunlukla metamorfoz ve toz yeme geçiş süreci ile ilişkili olduğu bulunmuştur. Tripsin ve kimotripsin speisifk aktiviteleri larvalarda ağız açılımı ile birlikte ilk olarak 3. günde tespit edilmiş ve 25. güne kadar yavaş bir artış göstermiştir. Pepsin aktivitesi ise mide oluşumu ile eş zamanlı olarak ilk kez 28. günde gözlenmiş ve 30. güne kadar ani bir artış sergilemiştir. Amilaz ve lipaz aktivitesi ise sırasıyla 2. ve 4. günlerde izlenmiş ve sonrasında larval dönemin ilk haftası boyunca hızlı şekilde yükselmiştir. Ayrıca, pepsin dışındaki tüm sindirim enzimleri aktivitesi ilk olarak bükülme öncesi dönemde izlenmiş ve gastrik salgının başlangıcı ve fonksiyonel sindirim sisteminin oluşması sırasıyla bükülme ve bükülme sonrası dönemde tespit edilmiştir.Anahtar Kelimeler: Sindirim enzimleri, dönemsel ontogeni, larval gelişim, Dentex dentex, sinarit.

“…This results are in agreement with Suzer et al [34] who described in D. puntazzo larvae an increase in lipase activity to 20 DAH, then a slight decrease and a second increase from 35 DAH, after microdiet introduction. Similar lipase activities were found in some species such as P. erythrinus [70], D. sargus [75], Seriola lalandi [78], S. ocellatus [89], and S. senegalensis [92] larvae.…”

“…The variations observed in the specific activity of the alkaline proteases of D. puntazzo during larval development have been reported for many other species including S. aurata, D. sargus, and S. lalandi [75,78]. These fluctuations may be explained as a response to changes in the amount and composition of the food provided (first live prey and after commercial feed) [5,79] and as change in the expression of different enzymes as a response to variations in larval metabolism.…”

Abstract:The ontogenetic development and pattern of main digestive enzyme activities (proteases, carbohydrases and lipases) were investigated in farmed sharpsnout seabream Diplodus puntazzo larvae and juveniles, during the passage from the larval stage to adult (from 21 to 277 days after hatching -DAH). Larvae showed exponential growth, thus confirming that Rotifers and Artemia nauplii are suitable preys for early feeding of D. puntazzo larvae.Pepsin activity was low in the larvae, but it increased afterwards in relation with stomach development. In juveniles, levels of specific activity of trypsin, chymotrypsin and elastase were lower compared to that recorded in larvae. A decrease in the activity of the alkaline proteases could be related to an increase in the functionality of stomach. Qualitative and quantitative assay of glycosidases ( -amylase, cellulase and maltase) showed high glycosidase activity, indicating that D. puntazzo is capable of digesting carbohydrates in its diet. Levels of lipase activity in juveniles were higher than those found in larvae. Our results didn't show an inductive character of lipases, since in juveniles the activity levels were almost constant even if the fat content of compound diet varied (from 7.0 % to 20 %).The rapid changes in the digestive activities of D. puntazzo larvae supported the existence of well established induction and regulation digestive mechanisms. Present results also confirm that D. puntazzo larvae have complete digestive enzymatic equipment that increased during larval ontogeny and enable larvae to digest and absorb nutrients contained in live preys once exogenous feeding occurred. The enzymatic pattern is correlated with omnivorous feeding habits of the species. Moreover, the patterns of activity of the main digestive enzymes of D. puntazzo larvae and juveniles indicated the early functional development of their digestive system and suggested this species as a good candidate for Mediterranean aquaculture using the compound diet.

“…In a number of early studies, researchers found that although acid protease was usually present only after larvae started feeding, most of the alkaline proteolytic enzymes could be detected as early as the endogenous feeding stage in various fishes, such as herring Clupea harengus (Pedersen et al 1987), striped bass Morone saxatilis (Baragi and Lovell 1986), sea bass (Zambonino Infante and Cahu 1994), gilthead sea bream (Moyano et al 1996), Eurasian perch (Cuvier-Péres and Kestemont 2002), white bream Diplodus sargus (Cara et al 2003), and yellowtail kingfish Seriola lalandi (Chen et al 2006a). In our study, amylase, lipase, and alkaline phosphatase of the miiuy croaker larvae showed relatively high levels of activities prior to mouth opening on 3 dah.…”

The ontogenetic development of the digestive enzymes amylase, lipase, trypsin, and alkaline phosphatase and the effect of starvation in miiuy croaker Miichthys miiuy larvae were studied. The activities of these enzymes were detected prior to exogenous feeding, but their developmental patterns differed remarkably. Trypsin activity continuously increased from 2 days after hatching (dah), peaked on 20 dah, and decreased to 25 dah at weaning. Alkaline phosphatase activity oscillated at low levels within a small range after the first feeding on 3 dah. In contrast, amylase and lipase activities followed the general developmental pattern that has been characterized in fish larvae, with a succession of increases or decreases. Amylase, lipase, and trypsin activities generally started to increase or decrease at transitions from endogenous to exogenous feeding or diet changes, suggesting that these enzymatic activities can be modulated by feeding modes. The activities of all the enzymes remained stable from 25 dah onwards, coinciding with the formation of gastric glands and pyloric caecum. These results imply that specific activities of these enzymes underwent changes due to morphological and physiological modifications or diet shift during larval development but that they became stable after the development of the digestive organs and associated glands was fully completed and the organs/glands functioned. Trypsin and alkaline phosphatase were more sensitive to starvation than amylase and lipase because delayed feeding up to 2 days after mouth opening was able to adversely affect their activities. Enzyme activities did not significantly differ among feeding groups during endogenous feeding; however, all activities were remarkably reduced when delayed feeding was within 3 days after mouth opening. Initiation of larvae feeding should occur within 2 days after mouth opening so that good growth and survival can be obtained in the culture.
