“…Although their importance is recognized, there is still uncertainty regarding the specific contribution of each enzyme to the process of protein metabolism [59]; these enzymes, including amylase, may be present in the early stages of ontogenetic development, as has been described in several species [26,45,60]. In B. moorei these enzymes are present from hatching; the same behavior was observed in larvae of the species Centropomus undecimalis [61], Centropomus nigrescens [62], Centropomus viridis [63], Pseudoplatystoma punctifer [46] and Pseudoplatystoma fasciatum [64]. Each case, including the species being studied, showed peaks of activity which are specific to each species and may be the result of predetermined genetic factors [65], specific substrate requirements or variations in diet [66,67], feeding protocol [68], as well as physical factors such as temperature and species-specific differences, among others [18,[69][70][71][72][73][74][75].…”

Brycon moorei is an opportunistic omnivorous species. It is not known what its nutritional requirements are at any stage of its development; this study determined the influence of diet on the zootechnical parameters and enzyme activity of these fish. In a completely randomized quintuplicate design, an ad libitum dietary protocol was applied, which included Prochilodus magdalenae larvae, Artemia salina and balanced feed with increasing inclusion levels (35 to 55% crude protein (CP)). Larvae 22 h post-hatching (HPH), with an average initial weight and length of 3.07 ± 0.69 mg and 6.069 ± 0.22 mm, respectively, were seeded at a density of 17 larvae L−1 in tanks with an effective volume of 60 L. The main zootechnical parameters, water quality and enzyme activity were analyzed with respect to the experimental diets. Significantly, the best diet was that of 45% CP when compared with the other CP levels used. Specific serum enzyme activity was found from hatching, with fluctuating values, the specific pepsin-like activity started at 111 HPH. B. moorei larvae can receive a dry diet from 124 HPH and their requirement corresponds to 48.5% CP.

The spotted seatrout (Cynoscion nebulosus)—an important commercial species—has a high potential for aquaculture in the Gulf of Mexico. To optimize its feeding during larval rearing, this study aims to evaluate the primary gastric (pepsin), intestinal (leucine aminopeptidase and alkaline phosphatase), and pancreatic (alkaline protease, trypsin, chymotrypsin, amylase, and lipase) enzyme activities from hatching to day 30. A multivariate analysis identified three digestive enzyme development stages during the spotted seatrout larval transformation. The first stage occurred between 1 (mean ± standard error (SE) = 1.73 ± 0.14 millimeter (mm) standard length (SL)) and 3 (2.14 ± 0.07 mm SL) days after hatching (DAH); a period of digestive stability showed the highest activity in amylase and bile salt-dependent lipase. The second stage (from 4 (2.53 ± 0.09 mm SL) to 20 (10.92 ± 0.51 mm SL) DAH) was a period of digestive transition, during which leucine aminopeptidase, chymotrypsin, and alkaline proteases were identified as the predominant enzymes from 4 to 5 DAH. In the third stage—a period of digestive stability—pepsin was the major enzyme that occurred between 25 (16.51 ± 0.81 mm SL) and 30 (25.91 ± 0.82 mm SL) DAH. These results indicate that the spotted seatrout larvae have a digestive system adapted to lipids and carbohydrates at the onset of feeding, with an immediate transition to protein digestion when exogenous feeding begins. Additionally, the digestive system of the spotted seatrout may be considered mature at 25 DAH. Further research is needed to elucidate the mechanisms of digestive tract development in the spotted seatrout larvae.

“…Digestive enzymes play an essential role in digesting nutrients, such as starch, fat, and protein of feed (Garcıá-Meilań et al, 2016). Absorption capacities are affected by environmental factors such as photoperiod, stocking density, and biotic factors such as species and diet (Espinosa-Chaurand et al, 2017;Garcıá-Meilań et al, 2020;Hernańdez-Loṕez et al, 2021;Upadhyay et al, 2022). AMS, PES, and LPS activities of GIFT tilapia juveniles under LW and LR were higher, compared with LY and LB.…”

The light spectrum is a vital environmental factor for the culture of fish, and the welfare of farmed fish is a crucial issue in aquaculture. In this study, Nile tilapia (Oreochromis niloticus, GIFT strain) juveniles were exposed to full-spectrum (LW), red (LR), yellow (LY), or blue (LB) light. After the 45-day experiment, growth performance, stress responses, and aggressive behaviors were evaluated, and transcriptomic analysis was carried out. The results revealed that LW and LR positively affected growth performance. At the same time, LY and LB had a negative effect. Light spectrum induced stress responses of juvenile fish exposed to LY, under which the total antioxidant capacity (T-AOC) and cortisol (COR) contents were the highest. The activities of α-amylase (AMS), protease (PES), and lipase (LPS) in the digestive tract showed a similar tendency, indicating that the light spectra altered the digestive enzyme activities and then affected growth. Behavioral analyses showed increased chase and bite activities of tilapia juveniles exposed to LW and LY. The affected functions included the nervous system, muscle morphogenesis, and immune system-related regulation. Enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways include the tryptophan metabolism signaling pathway, protein digestion and absorption signaling pathway, Jak-STAT signaling pathway, arachidonic acid metabolism signaling pathway, and alpha-linolenic acid metabolism signaling pathway. Overall, light spectra influenced the welfare of farmed tilapia juveniles in terms of growth, stress, and behavior. Our results suggested that LR should be used in juvenile tilapia culture.
