“…Accumulated thermal stress following declines of 12°C (from 26°C to 14°C) provoked increases in blood lactate (Lac) and glucose (Glu) levels, indicating that fish used all their physiological resources to maintain a high metabolic rate that might eventually have allowed them to escape to warmer habitat if such was possible. Blood Glu changes observed in N. cyanomos followed similar trends as those seen in the red spotted grouper Epinephelus akaara (habitat temperature range 11.7°-26.3°C) exposed to a temperature decrease from 10°C to 4°C at a rate of 1°C•d −1 (Park et al, 2016), and in the genetically modified farmed tilapia, Oreochromis niloticus (optimal temperature range of 26°-29°C) after 24 h exposure to 13°C (He et al, 2015). Umminger (1970) studied in detail the role of serum Glu in providing energetic fuel in the killifish Fundulus heteroclitus (habitat temperature range 6°-35°C) exposed to extremely low temperature (−1.5°C).…”

The abundance of the alien, Indo-Pacific damselfish Neopomacentrus cyanomos on an oil-loading platform in the southwest Gulf of Mexico indicates that widely distributed platforms could facilitate the expansion of its geographic range across the western and northern fringes of the Gulf. From there it likely will spread to other areas of the Greater Caribbean. The lionfish example demonstrates that it eventually happens, and can do so rapidly. Reduced temperature effects on the physiology of this species were examined to better predict its survivability in the northern Gulf during winter, when sea surface temperatures fall as low as 15°C along the coast. Overall, our results show that when the degree of experimental temperature decline was large and rapid, no compensation occurred and the stress response observed mostly reflected cellular processes that minimized damage. Integrated biomarker response values were significantly different between fish rapidly exposed to colder vs. warmer temperatures (declines of −4°C each day, from 26 to 14°C), reflected in higher values of blood metabolites and routine metabolic rates observed in fish exposed to 14 and 18°C respectively, and lower activity of all enzymes, lower protein carbonylation, and higher oxidative damage to lipids in fish exposed to 14°C. While the physiological proxies responded to minimize damage during the rapid-decrease experiment, the same proxies reflected the consequences of compensation when fish were thermally challenged after a 45 days acclimation at 18°C. In this case, lower values of blood metabolites and high antioxidant levels and indicators of damages underpinned its pejus lower range. Based on the results of the present work, it seems clear that low winter SSTs in the northern Gulf will slow down the colonization of the inshore area of N. cyanomos. We suggest that the use of physiological cellular stress markers on specimens acquired at the beginning of an invasion should be implemented in new standardized experimental protocols, including both rapid increases/decreases of temperature and post-acclimation temperature challenges, to assess the invasiveness potential of aquatic species such as this. in 2013, on coastal reefs near Coatzacoalcos (González-Gándara and Cruz-Francisco, 2014). Since then, the species was found on other reefs to the east and northwest of that location (de la Cruz-Francisco et al., 2015;Robertson et al., 2016), and more recently on oil platform

“…TP level is commonly used to diagnose fish health and disease, and its typically range is from ~4 g / dL to ~7 g / dL in fish (Yanagisawa & Hashimoto, 1984). When fish are under stress, the primary response increases the plasma cortisol, and the protein level increases as a secondary response (Davidson, Davie, Young, & Fowler, 2000). Abdelkahlek, Ghazy, and Abdel-Daim (2015) observed low levels of TP in fish under stress.…”

The oxygen consumption and wellbeing of hybrid grouper Epinephelus fuscoguttatus × E. lanceolatus (TG × GG) juveniles were evaluated after 60 days of being exposed to different salinities (10, 15, 20, 25, and 30 psu) in triplicate (20 fish / tank; 55.0±1.0 g body weight; 12.0±0.5 cm total length). The fish were fed daily with commercial pellet (42% protein, 9% ash, and 11% lipid).Results showed that the oxygen consumption rate (OCR)was significantly lower at15 psu but higher at 25 and 30 psu, indicating the high metabolic rate of fish in high salinities. The fish's wellbeing was monitored through growth and blood parameters. The fish cultured at 15 psu grew better in terms of final body weight, specific growth rate (SGR), feed efficiency (FE), and condition factor (CF) as compared with the fish at other salinities. Blood hematologic parameters were significantly higher in 15 psu but lower in 25 and 30 psu, whereas blood biochemical parameters were significantly lower in 15 psu but higher in 25 and 30 psu compared with other salinities. Overall, the TG × GG hybrid grouper showed the best OCR and wellbeing when cultured in 15 psu salinity. The findings will be useful in further studies on the management of TG × GG hybrid grouper.

“…Studies have shown that physiological modifications in fish can impair both specific and nonspecific immunity, leading to a high incidence of diseases (Wendelaar- Bonga, 1997;Si et al, 2019;Ghorbani et al, 2021). On the other hand, stress encourages the synthesis of blood metabolites, including corticosteroids and catecholamines as well as the increased levels of oxidative stress markers in fish (Park et al, 2016;Stara et al, 2018;Shamohamadi et al, 2021).…”

Background: The transportation of fish is a common practice in aquaculture. However, the transportation of fish results in significant stress that can cause mortality and disease outbreaks due to compromised immune status. To ameliorate the effect of this stress, it is advocated that a suitable antioxidant be supplemented to fish before subjecting to transportation. Objectives: The present experiment was performed to evaluate the effect of melatonin on haematological parameters and water quality indices of Clarias gariepinus post-transportation. Methods: Forty adult C. gariepinus fishes, weighing an average of 450.46 g and measuring an average of 38.23 cm and 4.46 cm were used for the experiment. They were divided into two groups. Group I (MMF) was supplemented with melatonin in their feed every day for one month while group II (OMF) was not administered melatonin. The subjects were fed a commercial pelleted diet once a day throughout the experiment. They were maintained in a tank made of plastic, and water was originally provided through a flow-through system. Haematological and water quality parameters were determined before and after transportation. Results: After the transportation process, erythrocyte count and packed cell volume of the group I was significantly higher (P<0.05). In comparison to group II, the total leucocyte count, neutrophil count, and neutrophil/lymphocyte ratio of group I were all significantly lower (P<0.05). After transit, group II had considerably higher quantities of nitrite, nitrate, and ammonia (P<0.05) than group I. Following transportation, group II had significantly higher nitrite, nitrate, and ammonia (P<0.05) than group I. However, in group I, dissolved oxygen concentration was greater (P<0.05) than that of group II. Conclusion: Accordingly, it was concluded that melatonin affected various haematological and water quality variables in C. gariepinus and will ameliorate the stress of transportation.
