Specialists in acoustic evaluation of Chilean Width Biomass (IFOP) and Peru (Imarpe), met in Valparaíso.
August 1st, 2025
Between July 21 and 25, 2025, the Hydroacoustic Specialists of the Institute of Fishing Development of Chile (FOP) and of the Peruvian Sea Institute (IMARPE) met in Valparaíso, in order to estimate the biomass of the shared stock of Width (Empharulis Ringens) in southern Peru and Northern Chile (Spch). This activity is part of the work program designed within the framework of the Chile-Peru Gef-PNUD Subpesca/Vice Project Ministry of Fisheries “Humboldt II”.
In this way, the historical series of the estimation of the biomass shared anchovtea spnch will begin to feed models that represent the size of the stock that supports the fishery of this important resource in the two countries.
In this regard, Jorge Castillo, IFOP researcher said “of the long series of data that each country has, we worked on the cases in which there is a temporary coincidence between the cruises made in each country, being considered as a continuous sampling in space and time, for this occasion we have worked with the 2023, 2022, 2021 and 2020 years and in future instances it will advance with the remaining years.
We have analyzed the different biological aspects, sampling design and the methodological approaches used to finally obtain results that are useful for stock modeling.
Taking advantage of the visit of Peruvian researchers and the coincidence that BC Abate Molina was in Valparaíso preparing the sail to investigate the common hake, a visit on board was made. Ramiro Castillo, General Director of Research in Hydroacoustic, Remote Sensoring and IMARP researchers to do their work.
