“…In detritivore estuarine-dependent fish, such as M. liza, a similar modulation of the liver and muscle glycogen concentration was observed during shorter times of feeding restriction (Albanesi et al, 2022). The maintenance of free glucose levels in the muscle at different times after feeding without a decrease in glycogen concentration suggests the use of circulating glucose for synthesis of this glycogen reserve in juveniles of P. orbignyanus.…”

“…Due to environmental factors or behavioral patterns that limit access to food, various fishes are exposed to different times of feeding restriction (Ensminger et al, 2021; Secor & Carey, 2016). In many animals, upon temporal shifts in feeding conditions, the modulation of the activity of digestive enzymes and of the concentration of energy reserves is a key response leading to digestive and metabolic adjustments (Albanesi et al, 2022; Karasov et al, 2011; Lallès, 2020). The determination of the activity of digestive enzymes at distinct times after feeding permits us to establish the postprandial temporal dynamics of central components of the metabolism of carbohydrates, proteins, and lipids and also to evaluate the potential effects of variable periods of food restriction on digestive parameters (Caruso et al, 2014; Pujante et al, 2018).…”

The concomitant determination of the concentration of energy reserves in storage sites and morphological traits permits a further integrative understanding of the possible adjustments in digestive/metabolic parameters and body conditions (Albanesi et al, 2022;Albanesi, Radonic, et al, 2021;Caruso et al, 2014;Pujante et al, 2018). Although food restriction can generally have negative effects on fish metabolism and physiology (Choi et al, 2012;Yang et al, 2019), in various species it is beneficial in response to multiple stresses (Ensminger et al, 2021;Lu et al, 2019).…”

Integrative studies are lacking on the responses of digestive enzymes and energy reserves in conjunction with morphological traits at distinct postprandial times in marine estuarine‐dependent flatfishes of ecological and economic importance, such as Paralichthys orbignyanus. We determined total weight (TW), hepato‐somatic index (IH), activities of digestive enzymes in the intestine, and the concentration of energy reserves in the liver and the muscle at 0, 24, 72, and 360 h after feeding in juveniles of P. orbignyanus. Amylase activity decreased at 72 h (about 30%). Maltase, sucrose, and lipase activities reached peak at 24 h (67%, 600%, and 35%, respectively). Trypsin and aminopeptidase‐N activities at 24 and 72 h, respectively, were lower than those at t = 0 (53% and 30%). A peak increase in the concentration of glycogen and triglycerides in the liver (24 h) (86% and 89%, respectively) occurred. In muscle, glycogen and triglyceride concentrations were unchanged at 24 h and higher at 72 and 360 h (100% and 60%). No changes were found in TW, IH, free glucose in the liver and muscle, and protein in the liver. The protein concentration in the muscle sharply increased at 24 and 360 h after feeding (60%). The results indicate a distinct and specific response of central components of carbohydrate, lipid, and protein metabolism that could be adjustments at the biochemical level upon periods of irregular feeding and even of long‐term food deprivation inside coastal lagoons or estuaries. The distinct responses of digestive enzymes in the intestine and energy reserves in the liver and muscle suggest the differential modulation of tissue‐specific anabolic and catabolic pathways that would allow the maintenance of physical conditions.

Differential digestive and metabolic profile of juveniles and adults of the estuarine-dependent marine fish Mugil liza (Mugilidae) cohabiting inside a southwestern Atlantic coastal lagoon

Integrative studies on intraspecific differences of digestive enzymes, energy reserves and morphological/somatic traits in juveniles and adults of estuarine-dependent marine fish while inhabiting inside a coastal lagoon are lacking. This study was carried on juveniles and adults of Mugil liza (Valenciennes, 1836) inhabiting inside Mar Chiquita Coastal Lagoon (Argentina). Both stages exhibited amylase, maltase, sucrase, lipase, trypsin and aminopeptidase-N (APN) activities in the intestine, which were active over a wide range of pH and temperature and exhibited Michaelis-Menten kinetics. Adults exhibited higher intestinal coefficient (31%), higher amylase (32%) and lower maltase (82%) and lipase activities (38%). Glycogen concentration in liver and muscle was similar while free glucose concentration was higher in adults (772% and 400% respectively). In adults retroperitoneal fat (absent in juveniles) constituted the main triglycerides storage site, while triglycerides concentration in liver and muscle was lower (86% and 80% respectively) than in juveniles. No differences were found in protein concentration in any storage organ. The results show that juveniles and adults exhibit a digestive and metabolic profile at the biochemical level and intraspecific differences in key components of carbohydrate and lipid metabolism that could support preparation for reproductive migration of adults outside the coastal lagoon.
