“…The rates of AP recovery were also similar to values previously reported for anaerobic muscle from fishes (Curtin et al, 1997;Hardewig et al, 1998;Nyack et al, 2007), mollusks (Bailey et al, 2003) and other crustaceans (Onnen and Zebe, 1983;Hansen et al, 1986;Morris and Adamczewska, 2002;Boyle et al, 2003). Data from the three species used in the present study had a combined body mass scaling exponent of -0.12 (Fig.…”

SUMMARYWe examined the influence of intracellular diffusion of O 2 and high-energy phosphate (HEP) molecules on the scaling with body mass of the post-exercise whole-animal rate of O 2 consumption (V O 2) and muscle arginine phosphate (AP) resynthesis rate, as well as muscle citrate synthase (CS) activity, in three groups of tail-flipping crustaceans. Two size classes in each of three taxa (Palaemonetes pugio, Penaeus spp. and Panulirus argus) were examined that together encompassed a 27,000-fold range in mean body mass. In all species, muscle fiber size increased with body mass and ranged in diameter from 70±1.5 to 210±8.8 μm. Thus, intracellular diffusive path lengths for O 2 and HEP molecules were greater in larger animals. The body mass scaling exponent, b, for post-tail flipping V O 2 (b=-0.21) was not similar to that for the initial rate of AP resynthesis (b=-0.12), which in turn was different from that of CS activity (b=0.09). We developed a mathematical reaction-diffusion model that allowed an examination of the influence of O 2 and HEP diffusion on the observed rate of aerobic flux in muscle. These analyses revealed that diffusion limitation was minimal under most conditions, suggesting that diffusion might act on the evolution of fiber design but usually does not directly limit aerobic flux. However, both within and between species, fibers were more diffusion limited as they grew larger, particularly when hemolymph P O 2 was low, which might explain some of the divergence in the scaling exponents of muscle aerobic capacity and muscle aerobic flux.

The Northern krill, Meganyctiphanes norvegica (Crustacea, Euphausiacea) is widely distributed in the northern and northeastern parts of the Atlantic Ocean where it faces rapid variations in water temperatures and food. We studied the physiological potential of krill to compensate for environmentally induced metabolic changes. Two isoforms of the glycolytic key enzyme pyruvate kinase (PKI and PKII, EC 2.7.1.40) were partly purified from M. norvegica by anion exchange chromatography. Specific activities and catalytic properties of each isoform were determined in whole body extracts as well as in selected organs and tissues of males and females. Both PK-isoenzymes differed slightly in their temperature profiles, their activation energy and their molecular weights. PKI showed a high affinity for the substrate PEP and was not affected by fructose-1.6-bisphosphate (FBP). In contrast, PKII showed low affinity for PEP but was strongly activated by FBP, up to 40-fold. The specific PK-activity of whole organisms was lower in females (44.9 F 4.8 Ud g ww À 1 ) than in males (61.3 F 7.7 Ud g ww À 1). In females PK II represented 20% of the total PK-activity while it was only 10% in males. Highest PK activities were present in the hearts, the eyes, pleopods and in the thoracopods. In the stomachs and the midgut glands PK activities were low. Almost all organs contained PKI and PKII. However, PKI prevailed in the abdomens, the pleopods, the thoracopods, and in the thoracic muscles. PKII dominated in the eyes, the midgut glands and in the ovaries. Experiments showed that the tissue concentrations of FBP increased with food uptake and temperature. The expression of two PK-isoforms with different kinetic properties and the mediation of substrate affinity by FPB is a powerful tool to immediately regulate glycolytic energy flows in different organs. The krill is capable of adjusting energy consumption to changes in nutritional conditions as well as variations of environmental temperatures. D

“…It brings the animals to an advanced state of exhaustion in which the main muscle nucleotide is AMP rather than ATP and the AEC ratio is extremely low (Mendes et al, 2002;Albalat et al, 2009). AEC values in other crustacean species exercised to exhaustion have been reported to be between 0.5 and 0.7 (Onnen and Zebe, 1983;Gäde, 1984;Maguire et al, 2002) and in general, it is accepted that animals with AEC values lower than 0.5 are in a state of physiological collapse and will therefore very rarely survive (Sylvestre and LeGal, 1987). However, we report for the first time that N. norvegicus has a considerable ability to recover from these This high capacity of N. norvegicus to reverse the nucleotide inter-conversions could be related to their life-style of occupying burrows in the sediment, habitats that can often become hypoxic (Rice and Chapman, 1971).…”

“…In many cases recovery following muscular activity is characterised by a further increase of L-lactate and a degradation of glycogen (Weinstein and Full, 1992). This phase of anaerobic energy production during recovery may serve as a means to restore muscle function as rapidly as possible by prioritising the conversion of AMP to ATP and replenishing the phosphagen reserves (Livingstone et al, 1981;Onnen and Zebe, 1983). In N.…”

“…In relation to this, in other crustaceans the return of ATP and high-energy phosphates occurs more rapidly than the removal of L-lactate and the restoration of glycogen stores (Onnen and Zebe, 1983). Therefore, measures of nucleotides could be used in recovery experiments as a more reliable method for assessing the efficacy of different methods of live transport Morris and Oliver, 1999) in order to minimise economic losses due to poor survival.…”

Finally, animals in the winter were better able to endure further stresses (an emersion of 1 h while animals were transported to the commercial handling facilities).Therefore, as a code of practice it is advised that trawled N. norvegicus directed to the live trade should be allowed to recover for at least 4-6 h in on-board tanks, and extra care should be taken especially in the summer, if further stresses such as additional emersion are to be applied within the first 24 h after capture.
