Aquaculture Navigation

Aquaculture farms should be marked in accordance with the IALA Maritime buoyage System

• Farms are normally marked by special marks, lateral or cardinal marks
• Channels between aquaculture farms should normally be marked with lateral marks.
• Radar reflectors and reflective material should be considered.

Depending on the size and shape of the farm the minimum marking arrangement may range from a light in the middle of the aquaculture farm for small farms (sides or diameter ≤ 500) to lights and daymarks on corners or sectors on farms where sides are greater than 900 / 2,500 metres or radius greater than 2,000 metres, as shown below.
