“…Organisms were not able to maintain their glucose body contents. Since stabilising the glucose level in the haemolymph is essential for the regular functioning of the nervous, muscle and reproductive systems of the organisms (Buckup et al, 2008), one might expect that, even if glucose body content decreased, haemolymph glucose content would remain more stable. Unfortunately, our analytical procedure did not allow us to differentiate glucose in the haemolymph from cellular glucose.…”

SUMMARY Subterranean environments are characterized by the quasi absence of thermal variations (±1°C within a year), and organisms living in these biotopes for several millions of years, such as hypogean crustaceans, can be expected to have adapted to this very stable habitat. As hypogean organisms experience minimal thermal variation in their native biotopes, they should not be able to develop any particular cold adaptations to cope with thermal fluctuations. Indeed, physiological responses of organisms to an environmental stress are proportional to the amplitude of the stress they endure in their habitats. Surprisingly, previous studies have shown that a population of an aquatic hypogean crustacean, Niphargus rhenorhodanensis, exhibited a high level of cold hardiness. Subterranean environments thus appeared not to be following the classical above-mentioned theory. To confirm this counter-example, we studied seven karstic populations of N. rhenorhodanensis living in aquifers at approximately 10°C all year round and we analysed their behavioural, metabolic and biochemical responses during cold exposure (3°C). These seven populations showed reduced activities, and some cryoprotective molecules were accumulated. More surprisingly, the amplitude of the response varied greatly among the seven populations, despite their exposure to similar thermal conditions. Thus, the overall relationship that can be established between the amplitude of thermal variations and cold-hardiness abilities of ectotherm species may be more complex in subterranean crustaceans than in other arthropods.

“…Crayfish muscles are characterized by high levels of proteins (reaching 13.24% on dry matter) and low levels of lipids (less than 0.8% on dry matter). Particularly abundant are fatty acids containing long-chains of n3 PUFAs, such as EPA (C20:5n3) and DHA (C22:6n3) (Buckup et al, 2008), which are both highly appreciated by the consumers because they prevent cardiovascular pathologies (e.g. Thies et al, 2003).…”

Key-words: direct and indirect uses, surrogate species, option values, existence and bequest values, Crustacea Decapoda AstacideaTo face the severe loss in biodiversity recorded in freshwater crayfish (Crustacea, Decapoda, Astacidea), there is an increasing awareness that the CBD's concept of the sustainable use of natural resources should be applied also to this large assemblage of species. This review paper will synthesize the several uses we make or have made of crayfish with the purpose of pinpointing where sustainability is desirable and feasible. Uses are here classified as direct (i.e. consumption and production) and indirect. The latter uses refer to the recreational, cultural, ethical, aesthetic, scientific and education values of crayfish. An additional indirect use regards the environmental key role this taxon plays. Several examples, mostly related to Europe, will be provided to illustrate the importance of crayfish to human societies, culture and history. The potential of assigning a non-use value to them will be finally discussed. Pour faire face à la perte de biodiversité enregistrée pour les écrevisses d'eau douce (Crustacea, Decapoda, Astacidea), il y a une prise de conscience accrue que le concept de bioconservation (CBD) pour l'emploi durable des ressources naturelles devrait s'appliquer à ce large assemblage d'espèces. Cette revue veut synthétiser les nombreux usages que nous faisons ou avons faits des écrevisses avec le but de mettre le doigt sur les cas où la durabilité est souhaitable et faisable. Les usages sont classés ici en directs (i.e. consommation et élevage) et indirects. Ces derniers usages concernent la valeur récréative, culturelle, éthique, esthétique, scientifique et éducative des écrevisses. Un usage supplémentaire indirect concerne le rôle environnemental clé que ce taxon joue. Plusieurs exemples, la plupart pris en Europe, sont cités pour illustrer l'importance des écrevisses pour les sociétés humaines, leur culture et leur histoire. La possibilité de leur attribuer une valeur de non-usage est finalement discutée. RÉSUMÉ

“…The energy stored in the hepatopancreas can be transferred to other tissues for growth, molting and reproduction (Cuartas et al, 2003;Johnston et al, 1998;Wen et al, 2006). Hepatopancreas is the main tissue for lipid storage (Schmitt and Santos, 1993) while the muscle is the main place for protein storage in crustaceans (Buckup et al, 2008;Claybrook, 1983). In L. vannamei, protein can be converted to glycogen in the hepatopancreas and muscle through gluconeogenesis and glycogenesis (Rosas et al, 2001).…”

Molecular response of carbohydrate metabolism in Litopenaeus vannamei was evaluated at transcriptional level through quantitative real-time PCR analysis. The mRNA expressions of six genes hexose-6-phosphotransferase, pyruvate kinase, phosphoenolpyruvate carboxykinase, crustacean hyperglycemic hormone, glucose transporter and insulin-like growth factors binding protein in the hepatopancreas, muscle, gill and eyestalk were analyzed in shrimp fed different levels of carbohydrate and challenged with acute salinity stress. Among these genes, the relative expression of GLUT1, CHH and IGF-BP in the muscle was lower or nearly the same as the control group regardless of the dietary carbohydrate level. The relative expressions of HK and PK were much higher in the hepatopancreas, muscle, gill and eyestalk at 12 h after salinity stress. The relative expression of PEPCK showed a down-up-down tendency and the expression was much higher in different tissues (except in eyestalk) than in the control from 12 to 24 h after stress. This study indicates that there was no significant dietary carbohydrate regulation in muscle. The glycogen and amino acid in muscle were the main source energy for osmoregulation in L. vannamei when the animals were challenged with acute salinity stress. The muscle and gills were the main osmoregulation organ in shrimp under hypo-saline stress.
