“…Responses of freshwater species to water pH beyond the normal physiological range have been studied, with considerable changes observed in mucosal organs. In brond snout (Chondrostoma regium), acute exposure (i.e., 24 h) to high pH (9.8-9.9) caused gill lamella hyperplasia and fusion of secondary lamella, while exposure to low pH (4.4) resulted in club-shaped cells and hypertrophy of the epithelium [27]. In zebrafish (Danio rerio) gills, pH 4.0 increased the density of H + -ATPase-rich cells, involved in acid secretion and Na + secretion.…”

The skin, gills, and gut are the most extensively studied mucosal organs in fish. These mucosal structures provide the intimate interface between the internal and external milieus and serve as the indispensable first line of defense. They have highly diverse physiological functions. Their role in defense can be highlighted in three shared similarities: their microanatomical structures that serve as the physical barrier and hold the immune cells and the effector molecules; the mucus layer, also a physical barrier, contains an array of potent bioactive molecules; and the resident microbiota. Mucosal surfaces are responsive and plastic to the different changes in the aquatic environment. The direct interaction of the mucosa with the environment offers some important information on both the physiological status of the host and the conditions of the aquatic environment. Increasing attention has been directed to these features in the last year, particularly on how to improve the overall health of the fish through manipulation of mucosal functions and on how the changes in the mucosa, in response to varying environmental factors, can be harnessed to improve husbandry. In this short review, we highlight the current knowledge on how mucosal surfaces respond to various environmental factors relevant to aquaculture and how they may be exploited in fostering sustainable fish farming practices, especially in controlled aquaculture environments.

“…Maybe it could be necessary to make a digestibility study because of this kind of study rive due to how much of a given nutrient is digested by fish (Vilhelm et al, 2017). It can also be considered low metabolic waste because the waste production and dissolved oxygen consumption are similar (Mohammadi et al, 2019).…”

“…In pH, the optimal range is 6.5-9.0. This range may vary depending on the carbonated compounds present in water (Mohammadi et al, 2019). Optimal temperature ranges may vary depending on the species that are being cultivated, but this can be 24-30°C (Li, 2017).…”

The fish feed used in aquaculture systems has many nutritional factors like protein, fat, fiber, ash, and humidity; from these factors, one of great importance is protein. The protein of fish feed is obtained from fish meal, and the demand for fish meal has increased; this induces to increase the price. Many pieces of research have been done about this topic to mitigate this problem. This research shows the differences between three commercial foods of the different processes with the same quantity of protein, using tilapia Oreochromis niloticus, to prove any difference between NO2-, NO3-, and NH4+. Nitrogen compounds were determined with HACH methods for the DR6000 spectrophotometer. Biometric data were registered throughout the growth of fish, along with measure aerobic metabolism. Results have shown that has better outcomes related to low excretion of nitrogen compound was medium-cost fish feed (MCFF). It also has sound effects associated with the length-weight relationship; that could be connected to these fish feed's protein sources.

Temperature is critical in regulating virtually all biological functions in fish. Low temperature stress (cold shock/stress) is an often-overlooked challenge that many fish face as a result of both natural events and anthropogenic activities. In this study, we present an updated review of the cold shock literature based on a comprehensive literature search, following an initial review on the subject by M.R. Donaldson and colleagues, published in a 2008 volume of this journal. We focus on how knowledge on cold shock and fish has evolved over the past decade, describing advances in the understanding of the generalized stress response in fish under cold stress, what metrics may be used to quantify cold stress and what knowledge gaps remain to be addressed in future research. We also describe the relevance of cold shock as it pertains to environmental managers, policymakers and industry professionals, including practical applications of cold shock. Although substantial progress has been made in addressing some of the knowledge gaps identified a decade ago, other topics (e.g., population-level effects and interactions between primary, secondary and tertiary stress responses) have received little or no attention despite their significance to fish biology and thermal stress. Approaches using combinations of primary, secondary and tertiary stress responses are crucial as a research priority to better understand the mechanisms underlying cold shock responses, from short-term physiological changes to individual-and population-level effects, thereby providing researchers with better means of quantifying cold shock in laboratory and field settings.
