a proteomic analysis of the statocyst endolymph in common cuttlefish sepia officinalis an assessment of Acoustic trauma after exposure to sound
Scientific Reports, 2019Co-Authors: Marta Sole, Marta Monge, M Andre, Carmen QueroAbstract:Recent studies, both in laboratory and sea conditions, have demonstrated damage after sound exposure in the cephalopod statocyst sensory epithelium, which secretes endolymph protein. Here, the proteomic analysis of the endolymph was performed before and after sound exposure to assess the effects of exposure to low intensity, low frequency sounds on the statocyst endolymph of the Mediterranean common cuttlefish (Sepia officinalis), determining changes in the protein composition of the statocyst endolymph immediately and 24 h after sound exposure. Significant differences in protein expression were observed, especially 24 h after exposure. A total of 37 spots were significantly different in exposed specimens, 17 of which were mostly related to Stress and cytoskeletal structure. Among the Stress proteins eight spots corresponding to eight hemocyanin isoforms were under-expressed possible due to lower oxygen consumption. In addition, cytoskeletal proteins such as tubulin alpha chain and intermediate filament protein were also down-regulated after exposure. Thus, endolymph analysis in the context of Acoustic Stress allowed us to establish the effects at the proteome level and identify the proteins that are particularly sensitive to this type of trauma.

Acoustic Stress responses in juvenile sea bass dicentrarchus labrax induced by offshore pile driving
Environmental Pollution, 2016Co-Authors: Elisabeth Debusschere, Kris Hostens, Dominique Adriaens, Bart Ampe, Dick Botteldooren, Gudrun De Boeck, Amelie De Muynck, Amit Kumar Sinha, Sofie Vandendriessche, Luc Van HoorebekeAbstract:Underwater sound generated by pile driving during construction of offshore wind farms is a major concern in many countries. This paper reports on the Acoustic Stress responses in young European sea bass Dicentrarchus labrax (68 and 115 days old), based on four in situ experiments as close as 45 m from a pile driving activity. As a primary Stress response, whole-body cortisol seemed to be too sensitive to 'handling' bias. On the other hand, measured secondary Stress responses to pile driving showed significant reductions in oxygen consumption rate and low whole-body lactate concentrations. Furthermore, repeated exposure to impulsive sound significantly affected both primary and secondary Stress responses. Under laboratory conditions, no tertiary Stress responses (no changes in specific growth rate or Fulton's condition factor) were noted in young sea bass 30 days after the treatment. Still, the demonstrated acute Stress responses and potentially repeated exposure to impulsive sound in the field will inevitably lead to less fit fish in the wild.

biochemical responses of european sea bass dicentrarchus labrax l to the Stress induced by off shore experimental seismic prospecting
Marine Pollution Bulletin, 1999Co-Authors: Andrea Santulli, Alfonso Modica, Concetta Maria Messina, L Ceffa, Amelia Curatolo, G Rivas, G Fabi, Vincenzo DamelioAbstract:The paper reports the results of an experimental seismic survey in the open sea by an air gun, carried out to evaluate the effects of air gun Acoustic waves on marine animals. Air gun blast exposition was found to have a marked influence on confined Dicentrarchus labrax. Our data, in fact, demonstrated a biochemical response to Acoustic Stress induced by air gun blasts. Variations of cortisol, glucose, lactate, AMP, ADP, ATP and cAMP in different tissues of D. labrax, indicate that fish have a typical primary and secondary Stress response after air gun detonations. Radiography indicates that air gun blasts do not induce any macroscopic effect on skeletal apparatus. The variations of biochemical parameters returned within physiological values within 72 h indicating a rapid recovery of homeostasis after Acoustic Stress and no mortality was observed.
