In a WWF reserve of south-western Sicily (Italy), a population of Procambarus clarkii has coloniz. The other three tanks were used as a control condition without acoustic projection. The acoustic field inside an onshore open concrete tank for fish farming represented the onshore aquaculture noise conditions. Offshore aquaculture noise conditions were recreated as the typical acoustic field in proximity of an offshore sea cage for fish farming using a random sequence of quiet sea background and boat noises. The experiment lasted 120 days during which two different playlists of acoustic stimuli were projected inside six experimental tanks (each condition was replicated in three tanks). In particular primary, secondary (biochemical and haematological indexes) and tertiary (growth performances) stress responses were evaluated. more The present study evaluated the impact of sea background noise (the acoustic environment of the offshore aquaculture system) and onshore aquaculture system's ambient noise on welfare of gilthead sea bream juveniles (Sparus aurata). The present study evaluated the impact of sea background noise (the acoustic environment of the o. The ROI for the initial investment of the pin. ![]() The AP over 29 fishing days for the use of the pinger net with respect to the control net is 25.7 Euros for each 50 m of net. Moreover, was assessed the economic damage caused by the destroyed area of the nets. Considering the difference in the PPUE values of the two nets, the frequency of the dolphin interaction, and the effort of fishing activities, was assessed the one-year economic losses (ED) due to dolphin depredation. By comparing the data of the gross Profit Per Unit Effort (PPUE) over 29 fishing days for two identical nets (900-m long, one was equipped with pingers, and the other did not have pingers), was assessed the following: the different production trends of the nets (Advantage of Production, AP) and the Return Of Investment (ROI) for the purchase of the pingers. more In this study, an economic analysis of the effect of pingers as 'anti-depredation' devices on artisanal fisheries and dolphin depredation was performed. In this study, an economic analysis of the effect of pingers as 'anti-depredation' devi. di IAS – CNR il Dottor Mario Sprovieri e il Responsabile dell'IAS – CNR Sede Secondaria di Capo Granitola, il Dottor Giorgio Tranchida, hanno promosso e supportato le attivita del PCTO, anche quest'anno come negli anni pas. di Capo Granitola nell'ambito del Percorso per le competenze trasversali e per l'orientamento (PCTO ex ASL), e regolamentata dalla convenzione Prot. ![]() more Con la partecipazione ad Esperienza InSegna 2020 ( ) - Cambiamento climatico e sostenibilita ambientale - organizzata dall'Associazione PALERMOSCIENZA, da martedi 18 a domenica 23 febbraio 2020 presso l'Universita degli Studi di Palermo (Edificio 19 - Viale delle Scienze) - l'IAS – CNR porta a termine un'esperienza formativa di successo rivolta a 54 allievi delle classi III D e III E, indirizzo Scienze Applicate, del Liceo Scientifico 'Pietro Ruggeri' di Marsala (TP) presso l'IAS – CNR – S.
