Acoustical estimation of fish biomass: species identification and stocks management

Espinosa Roselló, Víctor; Calise, Lucio; Estruch, V. D.; Llorens Escrich, Susana; Ordoñez Cebrián, Patricia; Pérez Arjona, Isabel; Puig Pons, Vicente; Soliveres, Ester (Associazione Italiana di Acustica, 2015)

[EN] Acoustics is the basics of the most important technologies for underwater telecommunication, as well as for target detection and identification in the aquatic media. Multiple frequency measurements are the key for ...
Biomass estimation of bluefin tuna in sea cages by the combined use of acoustic and optical techniques

Puig Pons, Vicente; Espinosa Roselló, Víctor; Soliveres González, Ester; Ortega, Aurelio; Belmonte, Antonio; De la Gandara Garcia, Fernando (International Commission for the Conservation of Atlantic Tunas (ICCAT), 2012)

[EN] In this paper, an experimental setup to estimate the biomass of caged bluefin tuna (Thunnus thynnus) in the Spanish Mediterranean coast is presented. Aims are to monitor individual tuna during all stages of growth, ...
Detection and target strength measurements of uneaten feed pellets with a single beam echosounder

Llorens-Escrich, Susana; Pérez Arjona, Isabel; Soliveres, Ester; Espinosa Roselló, Víctor (Elsevier, 2017)

[EN] The possibility of detecting uneaten food pellets in aquaculture floating cages using a scientific single beam echosounder is demonstrated. The applied methodology is based in a basic scheme with the ultrasonic beam ...
Efficiency of parametric ultrasound generation in relaxing media for very shallow-water echo sounders

Ordoñez-Cebrian, Patricia; Jimenez, Noe; Espinosa Roselló, Víctor; Puig Pons, Vicente; Soliveres, Ester (2014-04)

Parametric acoustic generation provides the possibility to obtain narrow and nearly side-lobe free acoustic beams for low frequencies. In this way, the nonlinear interaction of two intense beams with close frequencies ...
Estimación de biomasa de peces en granjas marinas mediante ultrasonidos

Soliveres González, Ester (Universitat Politècnica de València, 2015-12-09)

[EN] Marine aquaculture production has increased considerably in recent years due to the scarcity of fisheries resources and increased demand. Gilthead sea bream and European sea bass are among the most interesting species ...
Estudio de la relación de las propiedades biométricas y acústicas de la dorada

Soliveres González, Ester (Universitat Politècnica de València, 2017-07-28)

El objetivo de este proyecto obtener una relación entre diferentes parámetros biométricos de ejemplares de dorada y sus parámetros acústicos. El conocimiento de esta relación es un paso indispensable para su detección ...
Mesures a distàncies pròximes del TS de la daurada: muntatge i calibratge del dispositiu experimental

Alberola Canet, Teresa (Universitat Politècnica de València, 2013-01-28)

This project's aim is to execute an experimental device assembly situated in Gandia's Port and to calibrate the transducers and echo sounder systems that will be used subsequently for the giltheade bream Target Strength ...
Monitoring of Caged Bluefin Tuna Reactions to Ship and Offshore Wind Farm Operational Noises

Puig Pons, Vicente; Soliveres, Ester; Pérez-Arjona, Isabel; Espinosa Roselló, Víctor; Poveda-Martínez, Pedro; Ramis-Soriano, Jaime; Ordoñez-Cebrián, Patricia; Moszynski, Marek; de la Gándara, Fernando; Bou-Cabo, Manuel; Cort, José L.; Santaella, Eladio (MDPI AG, 2021-11)

[EN] Underwater noise has been identified as a relevant pollution affecting marine ecosystems in different ways. Despite the numerous studies performed over the last few decades regarding the adverse effect of underwater ...
Propagation of sound beams behind sonic crystals

Sánchez Morcillo, Víctor José; Staliünas, Kestutis; Espinosa Roselló, Víctor; Pérez Arjona, Isabel; Redondo, Javier; Soliveres, Ester (American Physical Society, 2009-10)

A theoretical and experimental study of the propagation of sound beams in and behind two-dimensional sonic crystals at frequencies close to the band edges is presented. Beam focusing is predicted and discussed. We evaluate, ...
Simultaneous self-collimation of fundamental and second-harmonic in sonic crystals

Soliveres, Ester; Pérez Arjona, Isabel; Picó Vila, Rubén; Espinosa Roselló, Víctor; Sánchez Morcillo, Víctor José; Staliunas, K. (American Institute of Physics (AIP), 2011-10)

Simultaneous self-collimation of sound beams with different frequencies, corresponding to fundamental wave and to its second harmonic, is proposed theoretically and demonstrated experimentally. The result is obtained when ...
Target strength measurements of gilthead sea bream with single-beam quantitative echosounder

Llorens Escrich, Susana; Soliveres, Ester; Pérez Arjona, Isabel; Espinosa Roselló, Víctor; Puig Pons, Vicente; Ordoñez Cebrian, Patricia (Universidade do Porto, 2016-06-15)

[EN] Target strength (TS) measurements for ventral aspect of gilthead sea bream (Sparus aurata) have been performed in a scaled aquaculture cage. The measurements have been made with a Simrad EK-60 scientific echososunder ...
