Abstract Teleost fish are more diverse than any other vertebrate group, and yet only a limited number of species fished farmed globally. Efforts to expand the quantity diversity produced hampered by extreme ontogenetic responses fish, especially during larval development. This review looks at advances in molecular phylogeny, endocrine nutrient influences long‐term studies phenotypes commercially important put sources consequences this plasticity into context. nested context evolutionary...
The effect of common husbandry conditions (crowding, social environment, water quality, handling, and background color) on the cortisol stress response in adult zebrafish, Danio rerio, was investigated to check usefulness zebrafish as a model organism aquaculture research. In addition, noninvasive methodology for assessing evaluated. Zebrafish showed fast with high values at 30 min that returned basal levels within 2 h poststress. There significant positive correlation between trunk...
Zebrafish, Danio rerio, is an emerging model organism in stress and neurobehavioral studies. In nature, the species forms shoals, yet when kept pairs it exhibits agonistic anxiety-like behavior that leads to establishment of dominant-subordinate relationships. Fluoxetine, a selective serotonin reuptake inhibitor, used as anxiolytic tool alter aggressive several vertebrates antidepressant drug humans. Pairs male zebrafish were held overnight develop behavior, either treated or non-treated for...
The present study aimed to compare effects of increasing chronic stress load on the response European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata) identify neuroendocrine functions that regulate this response. Fish were left undisturbed (controls) or exposed three levels for 3 weeks then subjected an acute test (ACT). Chronic impeded growth decreased feed consumption in seabass, not seabream. In basal cortisol are high increase with load; a subsequent ACT decreases...
The haematological profile and a description of the cell types from peripheral blood six Mediterranean fish species are presented. highest haematocrit value was recorded in saupe, Sarpa salpa (P < 0.001), only herbivorous species, which also lacked monocyte cells. Eosinophils were absent European sea bass Dicentrarchus labrax. White bream, Diplodus sargus gilthead Sparus aurata had statistically significantly high numbers neutrophils low lymphocytes 0.001). different leucocyte not influenced...
The aim of this study was to examine species-specific differences in pre- and post-stress concentrations haematological, metabolic hormonal parameters two Mediterranean fish species, one with relatively high (European sea bass, Dicentrarchus labrax) the other low (meagre, Argyrosomus regius) basal blood cortisol concentrations, relation different water temperatures. Fish were reared net-pen cages exposed an identical acute stressor (crowding chasing a net for 5 min) three periods year....
Early life stress (ELS) shapes the way individuals cope with future situations. Animals use cognitive flexibility to their ever-changing environment and this is mainly processed in forebrain areas. We investigated performance of juvenile gilthead seabream, previously subjected an ELS regime. fish showed overall higher brain catecholaminergic (CA) signalling lower derived neurotrophic factor (bdnf) cfos expression region-specific All a normal cortisol serotonergic response acute stress.

Abstract Understanding the stress responses of organisms is importance in performance and welfare farmed animals, including fish. Especially fish aquaculture commonly face stressors, better knowledge their may assist proper husbandry selection breeding stocks. European sea bass ( Dicentrarchus labrax ), a species with high cortisol concentrations, major this respect. The main objectives present study were to assess repeatability consistency response identify differences liver transcription...

In the present study, we examined a disease caused by Aeromonas veronii bv. sobria in sea cage-farmed European seabass Dicentrarchus labrax, Aegean Sea, Greece. Commercial sized fish were affected A. and exhibited high morbidity mortality.

Two clinical bacterial isolates (Aero NS Aero PDB) identified as based on bacteriological characteristics sequence...
The majority of the genetic studies in aquaculture breeding programs focus on commercial traits such as body weight, morphology, and resistance against diseases. However, studying stress response European seabass may contribute to understanding component its future use select broodstock whose offspring potentially be less affected by handling. A total 865 were used measure weight response. Moreover, a disease challenge experiment with Vibrio anguillarum was conducted subset (332) above fish...
