4.5 Placement of the artificial structures

The disposal of reef units and/or reef sets inside an artificial reef group or complex needs to be planned on the basis of a range of criteria depending on the purposes of the artificial reef.

In the case of artificial reefs constructed as a fishing deterrent, the type of vessels to be deterred and the fishing gear used have to be taken into account when calculating the distance between the reef structures and their spatial disposition.
In artificial reefs deployed for fisheries enhancement, the spatial disposal of the reef units and/or reef sets should be planned on the basis of their individual area of influence towards the different fish species targeted, in order to optimize the reef effects on them.
More detailed information on the spatial disposal of the reef units and reef sets are given in Chapter 5.
