“…() described different optimum rearing temperature value depending on achieving maximum feed conversion efficiency or weight gain, as described also for Atlantic salmon post‐smolts (Handeland et al., ) as follows: FCR < growth < feed intake, as previously proposed by Jobling () who postulated that when fish were fed at unrestricted ration growth rate reaches its maximum at a lower temperature than that needed for achieving maximum ingestion rate. However, studies in other species such as rainbow trout ( Oncorhynchus mykiss ) (Bailey & Alanärä, ), hapuku ( Polyprion oxygeneios ) (Khan, Pether, Bruce, Walker & Herbert, , ), dusky kob ( Argyrosomus japonicus ) (Collett, Vine, Kaiser & Baxter, ), turbot (Árnason, Björnsson, Steinarsson & Oddgeirsson, ; Van Ham et al., ) striped bass ( Morone saxatilis ) (Duston, Astatkie & MacIsaac, ) and some species of the genus Seriola (Abbink et al., ; Bowyer et al., ) achieve their optimum FCR at the same temperature as optimum growth in agreement with the results obtained in the present study.…”

In order to successfully diversify Mediterranean aquaculture, it is necessary to determine optimum culture conditions of potential candidate species such as greater amberjack (Seriola dumerili). Among culture conditions, rearing temperature is a key factor for achieving optimum growth and maintaining fish welfare. However, little is known about the optimum culture conditions of greater amberjack (Seriola dumerili).Thus, the aim of this study was to determine the effect of three different rearing temperatures (17, 22 and 26°C) during 120 days on growth performance, body morphometry, biochemical composition, gut transit and liver morphology of greater amberjack (Seriola dumerili) juveniles. After 120 days of rearing, fish raised at 26°C showed higher (p < .05) body weight and specific growth rate than fish held at lower temperatures, as well as improved feed utilization, protein efficiency and nutrient retention percentages. Fish stomach emptying was faster (p < .05) in fish raised at 26°C than in fish held at 22°C and 17°C. Similar results were obtained for gut transit time, being gut emptying faster (p < .05) in fish reared at 26°C than in fish cultured at lower temperatures. Rearing temperature also induced changes in fish morphology which resulted in a higher (p < .05) caudal propulsion efficiency index for fish reared at 26°C. Based on these results, we conclude that greater amberjack fingerlings perform better at 26°C than at 22°C or 17°C.

“…The rise in metabolism is usually assessed via oxygen consumption, which in fully aerobic conditions is a proxy for proximate energy use and comprises the total costs of processing food (handling and digestion) and a variety of postabsorptive processes. These include the breakdown and synthesis of proteins, transport of absorbed materials, storage and growth (Peck 1998, Secor 2009, Khan et al 2015. Studies manipulating diets with materials that are not absorbed, such as cellulose, indicated that only 5%-30% of the SDA is used in handling food and digestion (Tandler & Beamish 1979, Carefoot 1990, and some studies showed food handling accounted for less than 3% of the metabolic rise (Cho & Slinger 1979).…”

Animals living in the Southern Ocean have evolved in a singular environment. It shares many of its attributes with the high Arctic, namely low, stable temperatures, the pervading effect of ice in its many forms and extreme seasonality of light and phytobiont productivity. Antarctica is, however, the most isolated continent on Earth and is the only one that lacks a continental shelf connection with another continent. This isolation, along with the many millions of years that these conditions have existed, has produced a fauna that is both diverse, with around 17,000 marine invertebrate species living there, and has the highest proportions of endemic species of any continent. The reasons for this are discussed. The isolation, history and unusual environmental conditions have resulted in the fauna producing a range and scale of adaptations to low temperature and seasonality that are unique. The best known such adaptations include channichthyid icefish that lack haemoglobin and transport oxygen around their bodies only in solution, or the absence, in some species, of what was only 20 years ago termed the universal heat shock response. Other adaptations include large size in some groups, a tendency to produce larger eggs than species at lower latitudes and very long gametogenic cycles, with egg development (vitellogenesis) taking 18-24 months in some species. The rates at which some cellular and physiological processes are conducted appear adapted to, or at least partially compensated for, low temperature such as microtubule assembly in cells, whereas other processes such as locomotion and metabolic rate are not compensated, and whole-animal growth, embryonic development, and limb regeneration in echinoderms proceed at rates even slower than would be predicted by the normal rules governing the effect of temperature on biological processes. This review describes the current state of knowledge on the biodiversity of the Southern Ocean fauna and on the majority of known ecophysiological adaptations of coldblooded marine species to Antarctic conditions. It further evaluates the impacts these adaptations have on capacities to resist, or respond to change in the environment, where resistance to raised temperatures seems poor, whereas exposure to acidified conditions to end-century levels has comparatively little impact.

“…While most previous studies report that the cumulative energy of SDA is relatively independent of temperature (reviewed in McCue, 2006;Secor, 2009), some have reported that SDA either increased (e.g. fish; Guderley and Blier, 1988;Khan et al, 2015) or decreased (e.g. leeches; Kalarani and Davies, 1994) at warmer temperatures.…”

The speed and metabolic cost of digesting a blood meal depends on temperature in a major disease vector

The energetics of processing a meal is crucial for understanding energy budgets of animals in the wild. Given that digestion and its associated costs may be dependent on environmental conditions, it is necessary to obtain a better understanding of these costs under diverse conditions and identify resulting behavioural or physiological trade-offs. This study examines the speed and metabolic costs -in cumulative, absolute and relative energetic terms -of processing a bloodmeal for a major zoonotic disease vector, the tsetse fly Glossina brevipalpis, across a range of ecologically relevant temperatures (25, 30 and 35°C). Respirometry showed that flies used less energy digesting meals faster at higher temperatures but that their starvation tolerance was reduced, supporting the prediction that warmer temperatures are optimal for bloodmeal digestion while cooler temperatures should be preferred for unfed or post-absorptive flies. 13C-Breath testing revealed that the flies oxidized dietary glucose and amino acids within the first couple of hours of feeding and overall oxidized more dietary nutrients at the cooler temperatures, supporting the premise that warmer digestion temperatures are preferred because they maximize speed and minimize costs. An independent test of these predictions using a thermal gradient confirmed that recently fed flies selected warmer temperatures and then selected cooler temperatures as they became post-absorptive, presumably to maximize starvation resistance. Collectively these results suggest there are at least two thermal optima in a given population at any time and flies switch dynamically between optima throughout feeding cycles.
