Haematological and Immunological Responses in Juvenile Sea Bass (Dicentrarchus labrax L.) After Short-Term Acute Stress
The physiological effects of acute stress (induced by an intraperitoneal injection) on the haematocrit, haemoglobin, serum cortisol and glucose, haemagglutinins and lysozyme were investigated in juvenile sea bass Dicentrarchus labrax. A total of 40 fish were subjected to an intraperitoneal injection. Eight fish were sampled at 0, 2, 4, 24 and 48 h after acute stress and compared to unstressed f...
متن کاملHaematological and physiological characteristics of diploid and triploid sea bass, Dicentrarchus labrax L
The purpose of this study was to determine whether diploid and triploid sea bass differed in terms of main haematological and physiological characteristics. Diploid and triploid fish were produced by sub-optimal pressure treatments and held in communal environments under standard rearing conditions. Total red blood cell count (RBCC), haemoglobin concentration (Hb), hematocrit (Hct), mean cell v...
متن کاملEarly exposure to chronic hypoxia induces short- and long-term regulation of hemoglobin gene expression in European sea bass (Dicentrarchus labrax).
European sea bass (Dicentrarchus labrax) inhabits coastal waters and may be exposed to hypoxia at different life stages, requiring physiological and behavioral adaptation. In the present study, we attempted to determine whether regulation of hemoglobin (Hb) gene expression plays a role in the physiological response to chronic moderate hypoxia in whole larvae and hematopoietic tissues (head kidn...
متن کاملAcute toxicity of ochratoxin-A in marine water-reared sea bass (Dicentrarchus labrax L.).
The toxic effects of ochratoxin-A (OTA) on sea bass, Dicentrarchus labrax L., have not been previously documented. A flow-through bioassay test system was conducted in two series and a total 180 of adult marine-reared sea bass was used to estimate the acute oral 96 h median lethal concentration (LC(50)) value and behavioral changes of OTA. The data obtained were statistically evaluated using Fi...
متن کاملSkin mucus proteome map of European sea bass (Dicentrarchus labrax).
Skin mucus is the first barrier of fish defence. Proteins from skin mucus of European sea bass (Dicentrarchus labrax) were identified by 2DE followed by LC-MS/MS. From all the identified proteins in the proteome map, we focus on the proteins associated with several immune pathways in fish. Furthermore, the real-time PCR transcript levels in skin are shown. Proteins found include apolipoprotein ...
