The invention relates to an improved submersible mollusc farm. According to the invention, a line of cables bearing the culture ropes and the cylindrical buoys which maintain said line horizontal is suspended from end floats. The end floats comprise a filling/emptying system using water by way of ballast, in order to raise or submerge the line by inflating said floats with air. Submerged tension buoys are connected to the aforementioned floats by means of tension cables and pulleys which are fixed to the dead weights provided at either end of the line. The vertical thrust of the above-mentioned tension buoys causes the pulley to stretch the cable and tauten the line.
