“…In contrast, Campelo et al (2018) observed an increase in serum levels of AST and ALT in Astyanax altiparanae fed the highest levels of lysine (1.5%-2.3%), and assumed that this was due to the increased deamination of excess lysine for energy production (Stone et al, 2003). and health status (Iwama et al, 1999), and can be induced by various stress factors, both abiotic such as temperature, or biotic such as starvation and refeeding (Antonopoulou et al, 2013) or a combination of them (Antonopoulou et al, 2020), or different dietary supplementations (Antonopoulou et al, 2014;Feidantsis et al, 2014). The insignificant effects noticed in the expression of HSPs in the current study could be due to the influx of free amino acids from the diets for protein synthesis as reported by (Hendrick & Hartl, 1993;Ronnestad et al, 1999), who they proposed that more HSPs will be required for a different aspect of protein metabolism including repair or translocation of newly synthesized protein caused by the availability of free amino acids from food.…”

As the demand for fish food increases globally, there is a need for the aquaculture industry to expand its farmed fish species base in order to increase productivity and sustainability. To unlock a species potential for aquaculture, the nutrient requirement of the fish in terms of protein, amino acids, lipids, minerals and vitamins must be well understood to ensure efficient nutrient utilization and rapid growth. The new development in aquafeed production has witnessed commercial fish feed industries incorporating large quantities of plant-based ingredient in fish feed formulation (Lee et al., 2020). However, the main constraint when alternative proteins of plant origin are used in the fish diets is the limiting content in some essential amino acids (EAA), mainly lysine and methionine. Lysine is

“…Figure 4 depicts the main stress indicators determined in S. aurata oxidative tissues during various seasons. Several works used these bioindicators to estimate stress responses in several fish species under various environmental conditions, including feeding, parasitism and temperature (Antonopoulou et al, 2017(Antonopoulou et al, , 2020Beaulieu & Costantini, 2014;Fuentes et al, 2012;Madeira et al, 2013Madeira et al, , 2014Sadangi et al, 2020;Vinagre et al, 2012). However, integrating data obtained from studies at different biological levels are needed.…”

Monitoring variations in proteins involved in metabolic processes, oxidative stress responses, cell signalling and protein homeostasis is a powerful tool for developing hypotheses of how environmental variations affect marine organisms' physiology and biology. According to the oxygen-and capacity-limited thermal tolerance hypothesis, thermal acclimation mechanisms such as adjusting the activities of enzymes of intermediary metabolism and of antioxidant defence mechanisms, inducing heat shock proteins (Hsps) or activating mitogen-activated protein kinases may all shift tolerance windows. Few studies have, however, investigated the molecular, biochemical and organismal responses by fishes to seasonal temperature variations in the field to link these to laboratory findings. Investigation of the impacts of global warming on fishes farmed offsore, in the open sea, can provide a stepping stone towards understanding effects on wild populations because they experience similar environmental fluctuations. Over the last 30 years, farming of the gilthead sea bream Sparus aurata (Linnaeus 1758) has become widespread along the Mediterranean coastline, rendering this species a useful case study. Based on available information, the prevailing seasonal temperature variations expose the species to the upper and lower limits of its thermal range. Evidence for this includes oxygen restriction, reduced feeding, reduced responsiveness to environmental stimuli, plus a range of molecular and biochemical indicators that change across the thermal range. Additionally, close relationships between biochemical pathways and seasonal patterns of metabolism indicate a connection between energy demand and metabolic processes on the one hand, and cellular stress responses such as oxidative stress, inflammation and autophagy on the other. Understanding physiological responses to temperature fluctuations in fishes farmed offshore can provide crucial background information for the conservation and successful management of aquaculture resources in the face of global change.

“…This fish is usually reared between 14 to 26 • C [84], and the preferred temperature range for rearing juveniles has been suggested to be between 26 and 30 • C [85]. A study investigating the effects of temperature on meagre, in the range of 20 and 26 • C, showed that most temperature-related stress markers were lowest at 26 • C [86].…”

Mediterranean Aquaculture in a Changing Climate: Temperature Effects on Pathogens and Diseases of Three Farmed Fish Species

Climate change is expected to have a drastic effect on aquaculture worldwide. As we move forward with the agenda to increase and diversify aquaculture production, rising temperatures will have a progressively relevant impact on fish farming, linked to a multitude of issues associated with fish welfare. Temperature affects the physiology of both fish and pathogens, and has the potential to lead to significant increases in disease outbreaks within aquaculture systems, resulting in severe financial impacts. Significant shifts in future temperature regimes are projected for the Mediterranean Sea. We therefore aim to review and discuss the existing knowledge relating to disease outbreaks in the context of climate change in Mediterranean finfish aquaculture. The objective is to describe the effects of temperature on the physiology of both fish and pathogens, and moreover to list and discuss the principal diseases of the three main fish species farmed in the Mediterranean, namely gilthead seabream (Sparus aurata), European seabass (Dicentrarchus labrax), and meagre (Argyrosomus regius). We will attempt to link the pathology of each disease to a specific temperature range, while discussing potential future disease threats associated with the available climate change trends for the Mediterranean Sea.
