“…Overall, our results regarding protein digestion contrast the usual trend described in marine fish species with carnivorous preference, where the decrease in specific activity of pancreatic proteases with development is compensated by increasing pepsin activity [5,37]. According to histological analysis [10], pinocytotic vesicles of the posterior intestine were evident until the end of the study period (99 dph).…”

“…Moreover, lipase activity peak in this study (29 dph) concurred with the full functionality of gall bladder at 25 dph [10]. Likewise, maximum lipase activity in Seriola rivoliana has been attributed to bile secretion, which plays an important part in emulsification and neutralization of chyme and a more efficient hydrolysis and absorption processes [37]. In any case, the activity pattern in our study also contrasts to the usual tendency in carnivorous species, where lipase specific activity generally increases during ontogeny [45].…”

Thick-lipped grey mullet (Chelon labrosus) is a candidate for sustainable aquaculture due to its omnivorous/detritivorous feeding habit. This work aimed to evaluate its digestive and growth potentials from larval to early juvenile stages. To attain these objectives the activity of key digestive enzymes was measured from three until 90 days post hatch (dph). Expression of genes involved in digestion of proteins (try2, ctr, pga2, and atp4a), carbohydrates (amy2a), and lipids (cel and pla2g1b), together with two somatotropic factors (gh and igf1) were also quantified. No chymotrypsin or pepsin activities were detected. While specific activity of trypsin and lipase were high during the first 30 dph and declined afterward, amylase activity was low until 57 dph and increased significantly beyond that point. Expression of try2, ctr, amy2a, and cel increased continuously along development, and showed a peak at the end of metamorphosis. Expression of pla2g1b, pga2 and atp4a increased until the middle of metamorphosis and decreased afterwars. Most of these trends contrast the usual patterns in carnivorous species and highlight the transition from larvae, with high protein requirements, to post-larvae/juvenile stages, with omnivorous/detritivorous feeding preferences. Somatotropic genes, gh and igf1, showed approximately inverse expression patterns, suggesting the establishment of the Gh/Igf1 axis from 50 dph.

“…The high levels of lipase early in ontogeny were most likely extra-intestinal, and this probably reflects the dependency of larvae on lipids mobilized from the yolk. A similar pattern of lipase activity was observed in the Asian sea bass (Srichanun et al, 2013), longfin yellowtail (Teles et al, 2019) and Persian sturgeon (Gilannejad et al, 2019) where the lipase activity was increased in the first few days post-hatch and then decreased as age increased. The switch from dependency on the yolk to an external food source presumably explains the progressive reduction in lipase to a minimum at metamorphosis in RT, CBT and the hybrid.…”

“…A short steady‐state phase after hatching and then an exponential increase in trypsin activity linked to start feeding seems a common event during fish larval development (Lemieux et al., 2003; Sahlmann et al., 2015; Teles et al., 2019). In general, from hatching to metamorphosis approximately four phases have been proposed for trypsin activity development in fish larvae (reviewed by Rønnestad et al., 2013).…”

Comparative ontogeny of the digestive tract ofOncorhynchus mykiss♀ xSalmo trutta caspius♂ triploid hybrids to their parental species

Hybridization or the crossing of individuals from the same species (crossbreeding) or different species (interspecific) offers the possibility of improving traits that benefit aquaculture. Hybridization in salmonids has been used to improve disease resistance, growth rates, manipulate sex ratios and to produce sterile fish (Bartley et al., 2000). For example, Salmo trutta x Salvelinus fontinalis hybrids are sterile (Scheerer & Thorgaard, 1983). The hybrids of Salvelinus namaycush x S. fontinalis (maintained at low pH, 5.5-7.2) and Salmo labrax x Oncorhynchus mykiss have increased growth rates relative to the parental species by day 200 post-hatch (Akhan et al., 2011), while O. mykiss x Salvelinus sp. and S. trutta x S. salar hybrids have increased disease resistance (Maynard et al., 2016). Despite the potential advantages of the salmonid hybrids, their exploitation for aquaculture is uncommon due to high mortality during embryonic stages and up until external feeding (Bartley et al., 2000). Nonetheless, there are some reports that triploidization can increase the viability of salmonid hybrids (Blanc & Maunas, 2005; Blanc et al., 2000; Scheerer & Thorgaard, 1983). One potential reason for high mortalities during the larval stage may be abnormalities in digestive tract function and for this reason characterization of gastrointestinal tract development and the nutritional physiology of fish larvae can contribute to overcome such problems (Rønnestad et al., 2013). Caspian brown trout, CBT, Salmo trutta caspius is one of the native cold water species with high potential for aquaculture in the

“…Considering the above, scientific and technological advances show molecular biology as an area of research that has not been fully explored, mainly in studies for this species and have focused mainly on cyprinids and mostly on marine species such as Lutjanus guttatus (Galaviz et al., 2011), Lates calcarifer (Srichanun et al., 2013), Totoaba macdonaldi (Galaviz et al., 2015), Salmo salar (Sahlmann et al., 2015), Sparus aurata (Mata‐Sotres et al, 2016), Centropomus poeyi (Asencio‐Alcudia et al., 2018), and Seriola rivoliana (Teles et al., 2019).…”
