“…Therefore, the differences in ACAP can be related to the low activity of some antioxidant enzymes and also to the depletion of non‐enzymatic antioxidant system, which are dependent on many molecules with antioxidant potential from exogenous sources, such as vitamins from feed (Carocho & Ferreira, ). A decrease of ACAP was also observed in the liver of Antarctic fish Notothenia coriiceps and is likely due to temperature change and related to a decrease in the enzymatic and non‐enzymatic antioxidants (Klein et al, ). In this sense, we agree that the total antioxidant capacity is a resultant force of antioxidants acting in synergism by counteracting the undesired oxidation in order to maintain the organism homeostasis.…”

In this study, the influence of temperature variation on the blood and oxidative stress parameters of pacu Piaractus mesopotamicus juveniles was evaluated. Fish were subjected to gradual changes of temperature, over 5 days, by 24°C until reaching to experimental temperatures 18, 21, 24 (control), 27 and 30°C. There were significant differences (p < .05) in glucose and lactate of blood in both the haematological relationships and oxidative stress parameters. Glucose levels increased at 30°C and decreased at 21°C. Lactate levels were highest at 18°C. While the haematocrit was higher at all altered temperatures, haemoglobin levels decreased at 21°C and increased at 30°C, causing alterations in haematimetric indices. In the liver, glutathione‐S‐transferase (GST) activity was reduced at 18°C while antioxidant capacity against peroxyl radicals (ACAP) was highest at 30°C. Thiobarbituric acid reactive substances (TBARS) increased at 18, 21 and 27°C. In the muscle, ACAP decreased at 27 and 30°C and TBARS increased at 30°C. The results indicate that the species shows sensitivity to temperature variations. Accordingly, we conclude that with short‐term temperature variations >3°C, it is possible to induce higher alterations in the observed parameters in pacu juveniles.

“…The same tendency of increased SOD levels at a temperature higher than the normal rearing temperature (21-25 • C) was also documented in the gills of Asian stinging catfish (Heteropneustes fossilis) reared at 32 • C [51]. Reduced gill glutathione peroxidase (GPX) activity was observed in Antarctic fishes, Notothenia coriiceps, and N. rossi after exposure to 4 • C for 1 day (long-term) in contrast to 2 • C for 6 days (short-term) [52]. The temperature at 20 • C can also activate a protective antioxidant defense response in gills of discus fish (Symphysodon aequifasciatus), as evidenced by the increase in SOD and GPX activities, compared to a temperature of 28 • C [53].…”

Mucosal Barrier Functions of Fish under Changing Environmental Conditions

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.

“…Animal organisms possess a true arsenal of protection against oxidative stress, which, in the normal way is very efficacy [30,31]. It has been shown that in aquatic organisms, oxidative stress can be induced by various compounds and rapidly generates reactive oxygen species (ROS) such as superoxide and hydroxyl radical, nitric oxide, hydrogen peroxide and singlet oxygen species, ozone or aldehydes reactive [32].…”

Cypermethrin Influence on Oxidative Status and Anxious Behaviour in Paracheirodon innensi Species

The non-discriminatory use of pesticides and herbicides to increase agricultural production has caused great concern, as these products are likely to reach the aquatic environment, thus representing a health problem for aquatic species, but also for humans. Cypermethrin, a pyrethroid type II insecticide, is widely used in agriculture, but also for pest control of plants and stored agricultural products, as well as for combating the biological vectors of human and animal diseases. The administration of cypermethrin to Paracheirodon innensi determined ample variations in the activity of oxidative stress enzymes and malondialdehyde concentration, in close correlation with the concentration used, but also the occurrence of some locomotor deficiency and an anxiety state.
