A new joint Argentine-Uruguayan evaluation campaign, led by the BIP Víctor Angelescu of the National Institute for Fisheries Research and Development (INIDEP), has commenced to assess the northern anchovy stock in the spring. The campaign, part of the Pelagic Fish Fisheries Program, will focus on estimating the population biomass, obtaining composition and vital parameters, and studying the acoustic response of anchovy and its fauna. The campaign will also conduct measurements, behavior and morphology studies of anchovy schools, and identify acoustic records and obtain fish samples. Activities include hydroacoustics, fishing biology, zooplankton, phytoplankton, ichthyloplankton sampling, and verification of microplastics and stable isotopes.
