Ultraviolet-B (UVB) radiation generates reactive oxygen species (ROS), which damage DNA, proteins, and lipids in aquatic organisms, including fish. This study evaluated UVB-induced oxidative stress several tissues of two marine teleosts, gilthead seabream (Sparus aurata) European seabass (Dicentrarchus labrax). Juveniles both were exposed to four treatments simulating underwater UVB (no, low, m...
The endoscopic and histopathological findings detected in Sparus aurata experimentally infected with third-stage Anisakis larvae without intermediate host are evaluated and discussed. In six fish, live nematode larvae were introduced by gastroscopy into the stomach. The first observation by endoscope, 15 days after challenge, showed the presence of some larvae at the level of gastric mucosa. An...
The gilthead sea bream (Sparus aurata L.) is a marine fish of great importance for fisheries and aquaculture. It has also a peculiar sex-determination system, being a protandrous hermaphrodite. Here we report the construction of a first-generation genetic linkage map for S. aurata, based on 204 microsatellite markers. Twenty-six linkage groups (LG) were found. The total map length was 1241.9 cM...
The protein and lipid composition of a vitellin isolated from eggs of Sparus aurata were characterized by SDS PAGE, N-terminal sequence analysis and lipid analysis by thin layer chromatography and gas chromatography. The lipoprotein complex contains proteins with apparent molecular weights of 69, 59, 23, 21 and 12 kDa and were characterized as vitellinogenin fragments by N-terminal sequencing. ...
The hypothalamus-pituitary-interrenal (HPI) axis, involved in the regulation of the neuroendocrine stress responses, presents important players such as corticotropin-releasing hormone (CRH, generally considered as the initiator of this pathway) and CRH-binding protein (CRH-BP, considered as an antagonist of CRH function). CRH and CRH-BP full-length cDNA sequences were obtained from Sparus aurat...
The presence of a Raphidascarid parasitic nematode Hysterothylacium aduncum (Rudolphi, 1802) in two sparid fish (Sparus aurata and Diplodus vulgaris) and one soleid fish (Solea solea) was investigated in this study. A total of 868 individuals; 385 S. aurata, 437 D. vulgaris and 46 S. solea were collected from the Mersin Bay between February 2013 and January 2014 and examined. Variations in the ...
