Recovery periods of cultured spiny lobster, Sagmariasus verreauxi juveniles: Effects of handling, force feeding, exercising to exhaustion and anaesthesia on oxygen consumption and ammonia-N excretion rates
TLDR
It is demonstrated that lobsters recover rapidly from handling and the increase in M ˙ O 2 induced by 2-phenoxyethanol demonstrated this is not an effective anaesthetic for reducing recovery periods and physiological stress associated with handling. Expand
Haemolymph glucose concentrations of juvenile rock lobsters, Jasus edwardsii, feeding on different carbohydrate diets.
Postprandial changes in haemolymph glucose concentration ([Glc]H) were measured in 4-day-fasted juvenile intermoult spiny lobsters, Jasus edwardsii, provided with meals composed of glycogen, maltose,Expand
Das Schicksal der Nährstoffe bei dem FlußkrebsOrconectes limosus
Summary1.U-14C-labelled glucose, amino acid mixture, palmitate, starch or protein were fed to the crayfish by means of a stomach catheter, 5 min to several hours after feeding determinations wereExpand
Gluconeogenic control adaptations in Cancer magister: hypodermal pyruvate kinase, an enzyme with high- and low-affinity states.
TLDR
During periods of inhibition of chitin synthesis, the increased levels of FDP would convert PK II into PK I, which would have the net effect of increasing flux through the pyruvate kinase reaction and thus funneling carbon into the Krebs cycle. Expand

TLDR
The hepato-pancreas of crayfish contains no enzyme comparable to mammalian D-amino-acid oxidase, according to suppositions of Sarlet et al. (1950), and the specific activities of GPT, GOT, GDH and L-serine dehydratase in the cray fish equaled those in mammals in order of magnitude. Expand

TLDR
Findings support the hypotheses that either the fatty acid composition in the structure lipids was maintained or that a C18∶2δ6,9-fatty acid was de novo synthesized and elongated analogous to the known vertebrate pathway. Expand

TLDR
During the course of the year distinct changes can be noted regarding the total concentration and composition of carbohydrates; the accumulation was most intensiv during winter, depletion in early spring and molt did not cause a similar effect. Expand
