“…In the present study, all of the analyzed digestive enzymes were present in American shad larvae at hatching, with the exception of pepsin, which indicated that the larvae have the initial ability to digest nutrients from live food, even before the onset of exogenous feeding. This finding is in agreement with the early detection of enzymes in a variety of other fish species (Rønnestad and Morais 2007;Asgari et al 2013;Farhoudi et al 2013;Nazemroaya et al 2015). In addition, the results also illustrate that the early appearance of enzymes was triggered by underlying genetic mechanisms, rather than induced by dietary intake (Buddington and Diamond 1989;Lazo et al 2000).…”

“…Many studies have detected specific amylase activity in fish hatchlings, such as D. dentex ), H. huso (Asgari et al 2013), and sobaity seabream (Sparidentex hasta) (Nazemroaya et al 2015). Although there has been some debate as to whether amylase production coincides with mouth Fish Physiol Biochem opening or is produced shortly thereafter (Suzer et al 2006;Tong et al 2012;Ma et al 2014b), it is likely that the observed variation is a result of genetic factors and species-species differences.…”

In order to assess the digestive physiological capacity of the American shad Alosa sapidissima and to establish feeding protocols that match larval nutritional requirements, we investigated the ontogenesis of digestive enzymes (trypsin, amylase, lipase, pepsin, alkaline phosphatase, and leucine aminopeptidase) in larvae, from hatching to 45 days after hatching (DAH). We found that all of the target enzymes were present at hatching, except pepsin, which indicated an initial ability to digest nutrients and precocious digestive system development. Trypsin rapidly increased to a maximum at 14 DAH. Amylase sharply increased until 10 DAH and exhibited a second increase at 33 DAH, which coincided with the introduction of microdiet at 30 DAH, thereby suggesting that the increase was associated with the microdiet carbohydrate content. Lipase increased until 14 DAH, decreased until 27 DAH, and then increased until 45 DAH. Pepsin was first detected at 27 DAH and then sharply increased until 45 DAH, which suggested the formation of a functional stomach. Both alkaline phosphatase and leucine aminopeptidase markedly increased until 18 DAH, which indicated intestinal maturation. According to our results, we conclude that American shad larvae possess the functional digestive system before mouth opening, and the significant increases in lipase, amylase, pepsin, and intestinal enzyme activities between 27 and 33 DAH suggest that larvae can be successfully weaned onto microdiets around this age.

“…Besides, it is the only pancreatic enzyme capable of self-activation, and activating other digestive enzymes as well (Nazemroaya, Yazdanparast, Nematollahi, Farahmand, & Mirzadeh, 2015). In other studies, trypsin activity was detected in embryos of Scophthalmus maximus L during cleavage, blastula, gastrula and hatching (Tong et al, 2013), in larvae of Sparodentes hasta (Nazemroaya et al, 2015) at the moment of hatching, red porgy on 3 dph (Suzer et al, 2007) and sea bass on 4 dph (Zambonino-Infante & Cahu, 1994). In other studies, trypsin activity was detected in embryos of Scophthalmus maximus L during cleavage, blastula, gastrula and hatching (Tong et al, 2013), in larvae of Sparodentes hasta (Nazemroaya et al, 2015) at the moment of hatching, red porgy on 3 dph (Suzer et al, 2007) and sea bass on 4 dph (Zambonino-Infante & Cahu, 1994).…”

“…Amylase activity present from cleavage may be explained by the idea of genetically programmed secretion of amylase, like trypsin, and not necessarily stimulated during the embryonic phase (Ma et al, 2005). In Sobaity sea bream larvae, the presence of amylase activity after hatching was reported (Nazemroaya et al, 2015), and also for Yellow kingfish (Chen, Qin, Kumar, Hutchinson, & Clarke, 2006). In disagreement with the present study, experiments with Scophthalmus maximus in the period of embryonic development showed absence of amylase activity, signalizing that for this species carbohydrates are less essential for energy metabolism (Tong et al, 2013).…”

Nile tilapia broodfish fed high‐protein diets: Digestive enzymes in eggs and larvae

The aim of this study was to assess the activity of gastric, pancreatic and intestinal digestive enzymes during the embryonic and larval development of Nile tilapia (Oreochromis niloticus) GIFT strain Aqua America® 1 obtained from a broodstock fed two levels of crude protein (CP). A total of 72 females and 24 males, 10 hapas, two CP levels (32% and 38%) and six phases of embryonic (cleavage, blastula, gastrula) and larval (hatching, 7 and 10 days post hatch, dph) stages were used. The eggs were collected in cleavage, blastula and gastrula stages, 300 mg was collected, and kept in cryogenic tubes in liquid nitrogen. For the samples at larval stage, the remaining eggs were separated according to crude protein level and kept in hatcheries and samples were collected on 7 and 10 dph the same way as before. A total of 48 samples were collected: at each protein level (32% and 38% CP), four samples were collected in each phase of embryonic and larval development. Statistical differences were not observed during embryonic development for acid proteases, trypsin, amylase and lipase activity at both levels of crude protein (32 and 38% CP). Differences for acid proteases were noticed on 7 dph; trypsin and amylase on 7 dph and 10 dph. Significant differences on blastula and 7 dph for protease; as for aminopeptidase, there was significant difference on 7 dph. The data indicated early appearance of digestive enzymes in Nile tilapia broodfish receiving 32% CP taking into account the rapid growth and development of this species.
