Research was carried out into the effect of partial and total fishmeal (FM) replacement by a vegetable animal proteins blend, as well inclusion microalgae in diets for gilthead seabream (Sparus aurata L.). Fish 64 g on initial weight were fed until apparent satiation 88 days. The control diet (FM100) contained FM main protein source, whilst FM25, FM10 FM0 diets, replaced 75%, 90% 100%, respecti...

Materials can be tailored on the nano-scale to show properties that cannot be found in bulk materials. Often these properties reveal themselves when electromagnetic radiation, e.g. light, interacts with the material. Numerous examples of such types of materials are found in nature. There are for example many insects and birds with exoskeletons or feathers that reflect light in special ways. Of ...

This study investigated the effects of exogenous lipase supplementation on growth performance, digestive enzyme activity and body chemical composition Sparus aurata L. A total 840 (7.72 ± 0.05g) were fed eight diets for 60 days. Diets coded Group 1: Control 1 (G1–14% Lipid); 2: 2 (G2–22% 3: 14% Lipid + 0.5 g (G3– g/kg); 4: lipid 1.0 (G4–1 5: 1.5 (G5–1.5 6: 22% (G6–0.5 7: (G7 g/kg) 8: (G8–1.5 g/...

Following the intensification of Mediterranean aquaculture over years, Sparicotyle (syn. Microcotyle) chrysophrii (van Beneden and Hesse, 1863; Microcotylidae, Monogenea) became one most pathogenic ectoparasites for gilthead seabream (Sparus aurata L.) aquaculture. It has demonstrated a remarkable versatility to expand its known host range, accomplish an efficient transfer between wild farmed s...

Ambient temperature is one of the most important environmental factors affecting physiological mechanisms and biochemical reactions of living organisms. Thus the effect of ambient temperature on HSPs and IGF-I gene expression levels in the liver and muscle tissues of Sparus aurata were investigated in this research. The levels of HSPs, and IGF-I gene expression of the liver and muscle of Sparus...
