Tridge summary

A scientific team will conduct an oceanographic campaign from October 21 to November 1st, using the Ramón Margalef ship to evaluate the population of anchovies and sardines between Cape Trafalgar and Cape San Vicente. The campaign will use acoustic methods, pelagic fisheries, and water sampling to comply with the International Council for the Exploration of the Sea's recommendations. Additionally, the campaign will include genetic studies of anchovies and sardines, tagging of sunfish, and is part of a series of campaigns aimed at estimating the abundance of juvenile anchovies and sardines.

A team of scientists and technicians from the Spanish Institute of Oceanography (IEO, CSIC) will carry out 21 transects perpendicular to the coast, between Cape Trafalgar and Cape San Vicente, for 17 days, evaluating by acoustic methods the abundance of juvenile anchovies and anchovies. sardines, in order to predict the size of the adult populations. This is the oceanographic campaign ECOCADIZ-RECLUTAS 2021-10 carried out by the ship Ramón Margalef. It is scheduled to conclude in the first week of November. This ship started the campaign on October 21. In addition, pelagic fisheries will be carried out to complement the acoustic studies and biologically characterize the analyzed species and a systematic sampling of the thermo-halin properties, dissolved oxygen, fluorescence, etc., of the water column will also be carried out to carry out an oceanographic characterization and environment of the area to be surveyed. This campaign serves to comply with the recommendations of the ...
