Descripción del proyecto WE WILL STUDY THE USUAL BEHAVIOUR OF FISH IN AND AROUND COMMERCIAL MARINE AQUACULTURE CAGES. BEHAVIOURAL PATTERNS WILL BE IDENTIFIED AND RELATED WITH THE REGISTERED SOUNDSCAPE BUT ALSO WITH THE EXISTENCE OF OTHER STRESSOR FACTORS. MAPPING OF SOUND LEVELS WILL BE PROVIDED THROUGH MEASUREMENTS AND NUMERICAL SIMULATION FOR DIFFERENT SOUND SOURCES, FOLLOWING THE MARINE STRATEGY FRAMEWORK DIRECTIVE (MSFD). SOUND CONCEPT ADDRESSED IN SONORA CONSIDERS BOTH PRESSURE AND PM ACOUSTIC COMPONENTS. BOTH VARIABLES WILL BE REPORTED AND CONSIDERED AS STRESSORS ACTING ON FISH. SONORA WILL STUDY THE EFFECTS OF NOISE PRODUCED BY TWO EMERGING BLUE ECONOMY INDUSTRIES, THAT ARE MARINE INDUSTRIAL AQUACULTURE AND SEABED EXPLOITATION, ON THE BEHAVIOUR AND PHYSIOLOGY OF DIFFERENT FISH SPECIES, HELPING TO IMPROVE KNOWLEDGE TO ESTABLISH POLICY ACTION FOR A BLUE ECONOMY TRANSITION.WE WILL FOCUS ON THE INFLUENCE OF NOISE ON COMMERCIALLY HARVESTED SPECIES CONSIDERING DIFFERENT GROWTH STAGES. SONORA WILL EVALUATE THE EFFECTS AT BEHAVIOURAL (E.G. SWIMMING DEPTH, COHESION) AND BIOCHEMICAL, CELLULAR AND MOLECULAR (E.G. CORTISOL LEVEL, GLUCOSE LEVEL, TOTAL CELL COUNT) LEVELS OF UNDERWATER ANTHROPOGENIC NOISE ON TWO COMMERCIAL FISH SPECIES IN TWO DIFFERENT EXPERIMENTAL CONDITION. THE BEHAVIOURAL EFFECTS WILL BE EVALUATED ON ADULTS AND/OR JUVENILE FISH WHILE BIOCHEMICAL, CELLULAR AND MOLECULAR EFFECTS WILL BE EVALUATED BOTH ON LARVAE THAN ADULTS AND/OR JUVENILE FISH. SONORA WILL MAINLY FOCUS ON CAPTIVITY SPECIMENS, WHICH WILL ALLOW A MORE IN-DEPTH STUDY IN RELATION TO BOTH LEVEL AND TEMPORAL THRESHOLDS ACCORDING TO THEIR BEHAVIOURAL AND PHYSIOLOGICAL EFFECTS. TO GUARANTEE THE ENVIRONMENTAL STATUS OF THE SELECTED AREAS, THE STUDIES WILL BE CARRIED OUT BY MEANS OF INSONIFICATION IN SHORT-TERM PERIODS AND NOT TO HARM ANY ANIMAL, THEY WILL BE LIMITED TO POPULATION SAMPLING.SONORA WILL MEASURE AND CHARACTERISE THE ACOUSTIC SIGNATURE OF TWO OF THE MAIN UNDERWATER NOISE SOURCES: ANTHROPOGENIC OPPORTUNISTIC SOURCE (SHIPS PROPELLER) AND SEISMIC SOURCE (AIR GUN). MODELLING OF THESE SOURCES AND THEIR PROPAGATION WILL BE CARRIED OUT. MODELS WILL BE VALIDATED EXPERIMENTALLY.SONORA WILL USE THE RECORDED SIGNALS AND THE PROPAGATION MODELS DEVELOPED IN THE PROJECT, TAKING INTO ACCOUNT EXISTING CONSTRAINTS; AS EXCITATION SOURCES TO STUDY THE BEHAVIOUR OF FISH.SONORA WILL DEVELOP THE FOLLOWING SOFTWARE TOOLS:- A PREDICTIVE SYSTEM, BASED ON NUMERICAL MODELLING OF NOISE SOURCE AND PROPAGATION AT SEA;- A MONITORING SYSTEM BASED ON A NETWORK OF VERTICAL BROADBAND HYDROPHONE ARRAYS COUPLED TO BUOYS;- A MONITORING SYSTEM OF THE ACOUSTIC LEVELS RECORDED DURING THE ENERGIZATIONS.A SPECIFIC MODULE OF THIS APPLICATION WILL MANAGE THE INPUT OF 3D SEAWATER PHYSICAL PROPERTIES DATA FROM THE COPERNICUS MARINE ENVIRONMENT MONITORING SERVICES, CMEMS (WWW.MARINE.COPERNICUS.EU) DATABASE AND FOR THE SEABED (ROCK OR MUD LAYER) FROM EXPERIMENTAL DATA.REACHING THE TARGETS OF SONORA WOULD PRODUCE AN ADVANCEMENT OF THE SCIENTIFIC KNOWLEDGE OF THE EFFECTS OF IMPULSIVE NOISE ON MARINE LIVING ORGANISMS. THE RESULTS OF THE RESEARCH WILL BE USED TO DRAFT GUIDELINES FOR CONDUCTING MARINE GEOPHYSICAL PROSPECTING ACTIVITIES, FOR SCIENTIFIC AND MINERAL EXPLORATION PURPOSES, THAT WILL REPRESENT AN ADVANCEMENT IN TERMS OF SCIENTIFIC QUALITY, DETAIL, AND EFFECTIVENESS.
