Última Contribution a l’étude écobiologique et biochimique du crabe "Carcinus aestuarii " dans la région nord de Sfax OceanDocs Baklouti Zouari, S. The main objective of this work is to study some biological aspects of Carcinus aestuarii Northern Sfax (biometry, reproduction, diet), and biochemical contents (water, protein, minerals, and fat). Analysis of metric characteristics of Carcinus aestuarii allowed us to determine the nature of the allometry between the width and différent parts of the body of the crab. For reproduction study, analysis of monthly changes in the gonadosomatic index (GSI) shows that the spawning period of Carcinus aestuarii North Sfax occurs from October to January. The analysis of monthly variations of the hepatosomatic index (HSI), shows that this species used the hepatic reserved to the maturity of gonads. The analysis of monthly variations of the sex-ratio shows that the... Tipo: Theses and Dissertations Palavras-chave: Biometrics; Biochemical analysis; Reproductive behaviour; Carcinus aestuarii. Ano: 2010 URL: http://hdl.handle.net/1834/5481 Copper Induced Lysosomal Membrane Destabilisation in Haemolymph Cells of Mediterranean Green Crab (Carcinus aestuarii, Nardo, 1847) from the Narta Lagoon (Albania) BABT Aliko,Valbona; Hajdaraj,Gerta; Caci,Atenisa; Faggio,Caterina. ABSTRACTDestabilisation of blood cell lysosomes in Mediterranean green crabCarcinus aestuarii was investigated using Neutral Red Retention Assay (NRRA). Crabs collected in Narta Lagoon, Vlora (Albania) during May 2014 were exposed in the laboratory to sub-lethal, environmentally realistic concentrations of copper. Neutral Red Retention Time (NRRT) and glucose concentration in haemolymph of animals were measured. The mean NRRT showed a significant reduction for the animals of the treatment group compared to the control one (from 118.6 ± 28.4 to 36.4 ± 10.48 min, p<0.05), indicating damage of lysosomal membrane. Haemolymph glucose concentration was significantly higher in the treatment group (from 37.8 ± 2.7 to 137.8.4 ± 16.2 mg/dL, p<0.05) than in...

Ano: 2015 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132015000500750 Osmoregulation and salinity-induced oxidative stress: is oxidative adaptation determined by gill function? ArchiMer Rivera-ingraham, Georgina A.; Barri, Kiam; Boel, Melanie; Farcy, Emilie; Charles, Anne-laure; Geny, Bernard; Lignot, Jehan-herve. Osmoregulating decapods such as the Mediterranean green crab Carcinus aestuarii possess two groups of spatially segregated gills: anterior gills serve mainly respiratory purposes, while posterior gills contain osmoregulatory structures. The co-existence of similar tissues serving different functions allows the study of differential adaptation, in terms of free radical metabolism, upon salinity change. Crabs were immersed for 2 weeks in seawater (SW, 37 ppt), diluted SW (dSW, 10 ppt) and concentrated SW (cSW, 45 ppt). Exposure to dSW was the most challenging condition, elevating respiration rates of whole animals and free radical formation in hemolymph (assessed fluorometrically using C-H(2)DFFDA). Further analyses considered anterior and posterior gills... Tipo: Text Palavras-chave: Antioxidant defense; Carcinus aestuarii; ROS production; Osmoregulation.
