Students from IES Santa Clara visited the El Bocal IEO fish farming research center in Santander, Cantabria to learn about advanced aquaculture technologies and techniques. They listened to presentations on obtaining plankton as the first fish feed, controlling feed quality through microscopic analysis, and wild and captive fish reproduction methods. The visit was part of a Comenius-funded EU project called Green Skills for Global Change aimed at improving students' experience with science.
