European Union provided funds for an acoustic assessment survey coordinated by
other Mediterranean countries known as the MEDIAS survey. The need to coordinate and standardize methodologies with other European Union countries meant that
the IEO had to switch their survey from autumn to summer, which is the anchovy
reproductive season and the sardine resting season.
Figure 16.17 and 16.18 shows distribution densities of the two most important
species in November and December.
Although anchovy abundance is highly variable between years, Fig. 16.17 provides an averaged representation, showing that the anchovy population is concentrated in Malaga Bay. The differential characteristics by port (Fig. 16.14) are a
representation of the map shown in this figure.
Although sardine abundance is highly variable between years, Fig. 16.18 provides an averaged representation, showing that sardines are distributed throughout
the whole northern Alboran zone with a greater abundance in the western area. The
differential characteristics by port (Fig. 16.14) are a representation of the map shown
in this figure.
16.6 Economic Aspects of the SMR (2002–2017)
Figure 16.19 shows the volume of landings and economic value of the species taken
by the purse seine fleet in the SMR. Sardines are the most caught species. Even
though the unit price of sardines is low, they are of great economic value to the
