Reliable stock identification constitutes an integral component of effective fishery management. Current methods for the putative units comprise analysis both phenotypic and genetic variability. The present study examined spatial variation in otolith morphology (shape asymmetry) composition 395 wild-caught Gilthead seabream (Sparus aurata) specimens, collected from Aegean Ionian Seas (eastern M...

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...

Social stress can affect the ability of fish to respond various stressors, such as pathogens or environmental variations. In this paper, effects social on gilt-head bream (Sparus aurata) were investigated. To study physiological stress, we evaluated biochemical and cellular parameters, cortisol, glucose, lactate, osmolarity, phagocytosis, 24 h after establishment hierarchy in a group three fish...

A 120-day experiment investigated the new organic raw materials for Gilthead seabream (Sparus aurata) feeding on growth, nutritional parameters, digestibility, and histology. An control diet (CON) three diets with 100% materials—the rest of rainbow trout, visceral Iberian pig, insects as a protein source (TRO, IBE, INS)—were tested. After experiment, histology were measured. The CON diet-fed ob...
