This study investigated the antioxidant enzyme activities in skin mucus of gilthead seabream (Sparus aurata L.) at 3 and 7 days post-wounding (dpw). The expression levels genes that encode stress proteins (grp170, grp94, grp75, sod hsp70) regeneration-related (tf, igf1, tgfb1, der1, apo1 erdj3) also were determined. Mucus samples obtained from left right flanks non-wounded wounded fish. In both...

Gilthead seabream (Sparus aurata) is vulnerable to low water temperature, which may occur in the Southern Europe and Mediterranean region during Winter. Fish are poikilothermic animals, so feed intake, digestion, metabolism ultimately growth affected by temperature. This study aimed evaluate performance, utilisation, nutrient apparent digestibility, N losses environment juveniles reared under t...

For the first time Ceratothoa parallela (Otto, 1828), a cymothoid isopod, is reported parasitizing cage-cultured gilthead sea bream Sparus aurata, in Greece. The specimens observed are larvae (Pullus secundus). They were found in the branchial and buccal cavity of young gilthead sea bream of 2 g mean body weight, upon introduction in the cages in an intensive cage farm facility. The species was...

Using reverse transcription-polymerase chain reaction and in situ hybridization, the expression of the prolactin (PRL) gene was determined during development in gilthead sea bream (Sparus aurata) for the first time. The mRNA for PRL was detected from the second day of the larval stage onwards. This transcript was also located in the adenohypophysial cells, starting at four days post-hatching an...

Knowledge of population structure and genetic diversity within between wild farmed populations gilthead sea bream (Sparus aurata) European seabass (Dicentrarchus labrax) is important to achieve sustainable aquaculture production these species assess the risk impacts fish escaped from farms. Previous studies on have been based a limited number markers samples. In this study, features were assess...

A challenge test for Photobacterium damselae subsp. piscicida (Phdp) resistance was carried out in two juvenile populations of gilthead seabream (Sparus aurata L.): F2_ATL and F0_MED. At 250 days post-hatching (dph), a fish plasma sample collected to measure humoral immune markers (peroxidase activity, bactericidal IgM immunoglobulin levels), at 272 dph were weighed inoculated with bacteria Phd...
