Pollutants have been reported to disrupt the endocrine system of marine animals, which may be exposed through contaminated seawater or through the food chain. Although 17α-ethynylestradiol (EE₂), a drug used in hormone therapies, is widely present in the aquatic environment, current knowledge on the sensitivity of marine fish to estrogenic pollutants is limited. We report the effect of the diet...

Since the specific binding of the antigen and immunoglobulin was discovered, multiple applications have been developed to asses different issues such as: (i) localization of cells and molecules in different cell compartments, (ii) characterization of functional subsets of cells, (iii) identification of different cell types, (iv) and specific blocking or enhancement of receptors or other protein...

The in vitro effects of four heat-inactivated bacterial species on the cellular innate immune responses of the gilthead seabream (Sparus aurata L.) were investigated. Head-kidney leucocytes were isolated and incubated for 30 min with two bacteria isolated from seabream skin (Pdp11 and 51M6; members of the Vibrionaceae and in the genus Shewanella) and two bacteria used as probiotics in humans an...

Given the pivotal role of Platelet-Activating-Factor (PAF) in atherosclerosis and the cardio-protective role of PAF-inhibitors derived from olive pomace, the inclusion of olive pomace in fish feed has been studied for gilthead sea bream (Sparus aurata). The aim of the current research was to elucidate the anti-atherogenic properties of specific HPLC lipid fractions obtained from olive pomace, o...

Different raw materials are routinely used in aquaculture feeds to satisfy the dietary nutrients required by species. There several components that should be taken into account evaluation of a particular ingredient feed formulation, such as digestibility, palatability and nutrient utilization interference. The aim this review was produce global overview about alternative fish meal oil for gilth...

Fish fortification with iodine-rich macroalgae (Laminaria digitata) and Selenium-rich yeast is expected to promote nutritional added value of this crucial food item, contributing a healthy balanced diet for consumers. However, it not known if steaming can affect these nutrient levels in fortified fish. The present study evaluates the effect on nutrients contents farmed gilthead seabream (Sparus...

In this paper, 981 reared juveniles of gilthead seabream (Sparus aurata) were analysed, 721 of which were from a commercial hatchery located in Northern Italy (Venice, Italy) and 260 from the Hellenic Center for Marine Research (Crete, Greece). These individuals were from 4 different egg batches, for a total of 10 different lots. Each egg batch was split into two lots after hatching, and reared...

In the present study, age, growth, length-weight relationship and reproduction were investigated in gilthead seabream (Sparus aurata L., 1758) collected from Beymelek Lagoon (Antalya, Turkey) between February 2006 and July 2007. The age, total length and weight of samples ranged from 0+ to 4 years, 10.6 to 35.5cm, and 18 to 928g, respectively. Growth was described by the standard form of the vo...

Abstract A trial was conducted to test the effect of partial replacement fishmeal by two brewery industry byproducts, yeast and spent grain, included in isoproteic (41% CP) isolipidic (22% CL) diets for gilthead sea bream (Sparus aurata) rainbow trout (Oncorhyncus mykiss), having mind availability these byproducts. first step before an ingredient is a commercial feed evaluate nutritional qualit...
