The Multi-annual Guidance Program (MAGP; 1987-1991) on artificial reef
s was first undertaken by the Spanish government under the supervision
of the European Economic Community. With this program, the Spanish go
vernment attempted to unify artificial reef construction criteria (i.e
., materials, design, place selection, etc.), as well as ensure proper
scientific assessment for all future artificial reefs to be establish
ed in the Spanish coastal zone. Before the 1987-1991 program, isolated
artificial reef projects were developed along the Spanish shore by di
fferent institutions. Very few of these artificial reefs were assessed
through base-line surveys before or impacts after their implementatio
n. During the MAGP, 35 artificial reefs were constructed. The main goa
ls of this Program were: 1) Protection of over-exploited coastal areas
from trawl fisheries; 2) Development of diversified habitats to enhan
ce biological production; and 3) To promote artisanal fishing in the s
urrounding areas. A brief description of the MAGP for 1992-1996 is als
o given.
