The Lycée de la Mer is located in the south part of the bay of Arcachon, Gironde.
It is divided into three sectors : general, technological and vocational. In the vocational section, there are several formations : boat maintenance, plastics, boat joinery and aquaculture.
In aquaculture there are two baccalaureates : marine aquaculture (oyster farming) which includes apprentices and students and fish farming with students only. There are about sixty students in marine aquaculture and fish farming. The students learn general educational subjects and professional subjects. They also have practical work and training periods in firms. The practical work timetable is annualized. It allows students to work whole weeks on the farm and understand better the cycles of life. Each week a different class is on the farm for six hours a day and four days a week. There are special areas dedicated to oyster farming and fish farming with ponds and a hatchery.
