Two oceanographic research vessels from the Ministry of Agriculture, Fisheries and Food have begun the Bioman 2023 campaign in the waters of the Bay of Biscay to analyse the anchovy and sardine populations, two of the species of greatest fishing interest in the area.

The ships will depart from the port of Pasajes under the scientific direction of the AZTI foundation. The Viscount of Eza will extend the campaign until May 26 and Emma Bardán, until the 31st.

The campaign design provides for continuous recording with acoustic methods to estimate the abundance of anchovy and sardines, determine spawning areas and opportunistic sighting of possible predators (birds and marine mammals) and characterization of the marine environment in the area.

In this investigation, an estimate of the biomass will be made from the daily egg production method, the determination of the laying area and the characterization of the hydrographic conditions.

With a multidisciplinary systemic approach, hydrographic parameters will be taken, the biodiversity of cetaceans, seabirds, sharks, fish and anisakis will be studied, analyzing the DNA of the water. On the other hand, the concentration of zooplankton will be determined and the distribution and abundance of microplastics on the surface will be obtained.

The study area covers the waters of the Exclusive Economic Zone (ZEE) of Spain and France, from the central Cantabrian Sea to the mouth of the Garonne River, and southern Brittany, where the Spanish purse seine fleet carries out its fisheries.

Research Vessels

The oceanographic vessels Vizconde de Eza and Emma Bardán are part, together with the Miguel Oliver, of the fleet of the General Secretariat of Fisheries. They are equipped with state-of-the-art technological equipment in navigation, as well as sophisticated scientific equipment for carrying out a wide range of multidisciplinary studies.

Both vessels carry out more than 500 research days each year in campaigns both nationally and internationally, embarking teams of scientists who evaluate the state of the fisheries to achieve the Maximum Sustainable Yield.
