PhD in Fisheries acoustics - I love scientific experiments, acoustic surveys, writing R scripts and figuring out sexy ways to visualize data

Happy to share our newly published article on target strength of Atlantic bluefin tuna (ABFT). The study developed at @azti_brta presents in situ measurements of target strength (TS) for ABFT obtained from a baitboat in the Bay of Biscay.

🌊🚢 The #Juvena2024 Survey starts on board the Emma Bardan vessel (@mapagob)🐟 We will estimate the abundance of juvenile anchovy, in a mission coordinated by @IEOoceanografia and @azti_brta.
🌟 Generating knowledge for the sustainable management of marine resources. 💙

Check out our web-based Multibeam Sonar Distortion Simulator. Developed at @azti_brta by @UdaneMartinez and myself, it is designed to correct estimates of school shape and size in sonar data to promote more selective fishing. https://t.co/HhjQZFSxqC

"🌊Exciting week at @AZTI_BRTA! Teamed up with @aquariumss to test the effectiveness of an acoustic camera in identifying fish species and sizes🐟. Tests conducted under controlled conditions at the Donostia Aquarium facility. ��� #SustainableFishing🎣 #AcousticSelectivity "

Our paper "Ecological risk assessment of a pelagic seabird species in artisanal tuna fisheries" is included in this @ICES_ASC themed set that explores the impacts of fisheries on #seabirds 👇

Last week, I had the honor of chairing the @ICES WGACEGG at @azti_brta, coordinating oceanographic surveys for abundance assessments of small pelagic species in southwestern European waters. Working towards #SustainableFisheries and effective #FisheriesManagement.

Processing the data obtained during the #Juvena2023 survey funded by @EkoGarapena and @mapagob to estimate the juvenile anchovy population in the Bay of Biscay, data that contributes to the responsible management of marine resources. #MarineConservation #BayOfBiscay #Anchovy

Hace poco que publicamos este vídeo sobre las olas de calor marinas. No hay mejor momento para recordarlo, aunque una ola de calor terrestre no es lo mismo que una marina

The consequences of a reduced resolution for acoustic-based abundances are an increase in uncertainty and the probability and magnitude of underestimation. Understand why in our recently published paper.

Last week I presented the lecture "Estimation of target strength of fish" in the “Erasmus Mundus WAVES Master” Summer School. This presentation summarises our experience from the last ten years of experiments and publications in this field of research. https://t.co/kKGKcmAsMa

Next week, I will be presenting a poster in the ICES Fisheries and Plankton Acoustic Symposium, held in Portland, Maine, USA. https://t.co/rMplGR96x5

Los científicos de @azti_brta @GuillermoBoyra y @UdaneMartinez estuvimos a bordo del PacificStar en Seychelles calibrando un sonar multihaz para mejorar su interpretación en un estudio financiado por #NextGenerationEU y la colaboracion de @albacora #sustainablefisheries

[GuillermoBoyra @GuillermoBoyra]

A simple method to correct sonar distortion caused by beam overlap could help species discrimination in fishing vessels, hence improving selectivity and achieving #sustainablefisheries using #underwateracoustics.
