Fig. 7. Design of a typical mussel farm in Taranto. The plan is arranged through the repetition of a basic unit, called “camera,” made with stakes driven into the bottom. The camera is always a square, laterally bounded and diagonally crossed by “lines.” Socks containing mussel nets are suspended from each line. This customary farming plan has recently been updated with polyethylene floats, known as “long lines,” which are a modern variant of the traditional system. Both systems are currently used in Mar Piccolo.
