“…As a result, in these studies, a large amount of MC-LR in the diet was released with the faeces, decreasing the MC-LR content in organisms. In our study, pure toxin was used, and the results suggested that the tolerance of aquatic organisms to MC-LR might be much lower than what has been reported previously (Vasconcelos et al, 2001;Tricarico, 2008). In fact, MC-LR has diverse effects on species and animal sensitivity highly changed with the organism, the variant, and the mode of exposure (Hansson, 2007).…”

“…Previous studies showed that, in natural lakes, P. clarkii accumulated more toxin in the intestine and less in the abdominal muscle (Tricarico, 2008). Other studies showed that, with regard to the oral route, cyanobacteria have higher toxic effects when fish were fed with crushed cells (released toxins) than when the fish were exposed to non-crushed cells (Jos et al, 2005).…”

The aim o f this study was to determine the acute toxicity effect and the accumulation of microcystin-leucine-arginine (MC-LR) on the crayfish Procambarus clarkii (Girard, 1852). Juvenile P. clarkii (5.47 ± 1.3 g) were cultured under 5 different MC-LR concentrations (0.3, 0.6, 1.2, 2.4, 4.8 mg/1), then the acute toxicity effect was observed. The median lethal concentration (LC50) of MC-LR on juvenile P. clarkii was 3.741 mg/1 at 24 h, 1.494 mg/1 at 48 h, 0.817 mg/1 at 72 h and 0.567 mg/1 at 96 h. Accumulation o f MC-LR was measured in different organs of mature P. clarkii (58.7 ± 3.8 g) exposed to 0.3 mg/1 MC-LR for 120 h. The detected MC-LR concentration decreased in the sequence: hepatopancreas > ovary > abdominal muscle > intestine. Hepatopancreas and ovary were found to be the main targets of the toxin. The results suggested that the MC-LR produced by cyanobacteria blooms could not only reduce the survival rate o f juvenile P. clarkii but also affect the fecundity of mature crayfish. This research also provides a reference basis for the detection and assessment of the pollution of water bodies in P. clarkii culture.

“…Additionally, P. clarkii is one of the most important vector of crayfish 'plague', carrying the pathogen (Aphanomyces astaci Schikora) as a chronic infection [18] and may also be an intermediate host for helminth parasites which can be transmitted to humans. Finally, P. clarkii is able to accumulate cyanobacterial toxins [19] and subsequently transfer them to their predators as well as to humans. Populations of P. clarkii are widespread in Europe, particularly in Spain, Italy and southern France, which have similar climatic conditions to Greece.…”

Enemy at the gates: introduction potential of non-indigenous freshwater crayfish in Greece via the aquarium trade

et al. 2013

View full text Add to dashboard Cite

Indigenous freshwater crayfish species (ICS) are important biodiversity components and desirable fishery targets. However, ICS populations are increasingly threatened by various anthropogenic stressors. Moreover, established populations of non-indigenous freshwater crayfish species (NICS) and new ‘waves’ of NICS introductions exert significant pressure on ICS populations at a pan-European level. These effects include direct competition for space and resources as well as crayfish ‘plague’ transmission from introduced North American species. Given low public knowledge of this problematic, considerable risk of future introductions exist as a result of conventional and internet-based aquarium trade, which often lead to deliberate and/or accidental releases of NICS into the wild. In 2011, we conducted a survey of freshwater crayfish species in eleven large-size pet shops located in three major cities and in three large internet-based aquarium companies in Greece. Overall, eight species belonging to three genera (Procambarus, Cherax and Cambarellus) were recorded, originating from the USA, Australia, New Guinea and Mexico. The invasion potential of the three most popular species was assessed using the Freshwater Invertebrate Invasiveness Scoring Kit (FI-ISK). Two species were determined to constitute a ‘very high risk’ of invasion. As such, regulatory measures need to be implemented to monitor the ornamental trade of NICS in Greece and a national framework developed for protecting ICS.

“…(Elder in the village of Vohiparara, Ranomafana National Park, Madagascar; after Jones, 2004) The most obvious use of crayfish is human consumption. As shown by Tricarico et al (2008), the abdominal muscle of P. clarkii has good nutritional qualities that are kept nearly constant during at least 21 days of stabulation at an ad libitum or restricted feeding regime. 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).…”

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
