Senior researcher Álvaro Saavedra, from Direct Evaluations Department participated in “ICES Fisheries and Plankton Acoustics Symposium – From Echosounders to the Cloud: Transforming Acoustic Data to Information.” international symposium , held in the city of Portland, USA, between March 27th and 30th, 2023, with two jobs.
Álvaro Saavedra presented the work titled: “Do fish swim faster in the horizontal direction than up-down?. Study case: two small pelagic fish and two demersal fish”, prepared by Älvaro Saavedra and Jorge Castillo, while research “Target Strength in-situ and ex-situ of anchoveta (Engraulis ringens) in the Southeastern Pacific” was presented in poster format ” by Jorge Castillo, Álvaro Saavedra, Javier Legua and Francisco Leiva. Participation in this symposium is of great importance for the department and institute, given the relevance of hydroacoustics in the evaluation of fish stocks for fishing resources management in our country and that it facilitates knowledge exchange with more than 300 researchers worldwide who make use of large amounts of data in acoustics instrumentation collection and treatment .
This symposium marks a relevant milestone in this technology application, incorporating artificial intelligence’s use and machine learning, among other modern techniques in data analysis. In addition, fishing acoustic community presented the latest advances in acoustic instrumentation new technologies development. Jorge Castillo stated that “in this symposium it will be possible to observe, among others, the use of the new manned and remote/autonomous platforms results to observe ecosystem components that could be one of the most interesting technological solutions for our country to prospect coastal sectors that until now have been expensive or impossible to monitor”.
It should be noted that this Acoustics and Fishing Technology Symposium sponsored by ICES (International Council for the Exploration of the Sea), constitutes the 8th scientific event, after 50 years, the first of which was held in Bergen, Norway (1973). Previous symposia have been held in Bergen, Norway (1973, 1982 and 2008), in Seattle, USA (1987), in Aberdeen, Scotland (1995), in Montpellier, France (2002) and in Nantes, France. (2015), highlighting that IFOP researchers have participated with the results of their work since 1982.
