Appendix 5. Areas estimation
5.1. Fishing Sector
The fishing area of each wilaya is not defined in the fishery statistics because the evolution of
the marine biomass is not limited by each wilaya’s administrative boundaries. However, the
estimate of the area available for the production of natural resources (BC) reflects the marine
and terrestrial fishing surfaces (lake-farming, dams), as well as the area exploited for
aquaculture. Therefore, it was essential to define the marine area exploited by fishers.
5.1.1. Delimitation of fishing grounds
The delimitation of the fishing zone was based on Decree 84-181 defining the baselines for
measuring the breadth of the maritime zones under national jurisdiction. This decree defines
the coordinates of this baseline. Moreover, this line was used as a starting limit for the
definition of the inshore, offshore and the total exclusive fishery zone.
Similarly, the length and the distribution of the different zones have been defined according
to the national legal texts:
- Article 30 of the 01-11 Law (related to fisheries and aquaculture).
- Decree N°18-96 (Presidential Decree N°18-96 of 2 Rajab 1439 corresponding to 20
March 2018, establishing an exclusive economic zone off the coast of Algeria).
- Executive Decree N°96-121 (Executive Decree N°96-121 of 6 April 1996, outlining the
conditions and modalities of Fisheries), and the Convention on Territorial Waters and
the Contiguous Zone.
Thus, the study considers the following two fishing areas:
- The inshore fishery (coastal zone), which covers area less than 6 miles.
- The offshore fishing area between 6-12 miles.
The surfaces of each area are described in the table (table 47). The offshore area allocated to
the aquaculture activity is also reported in the wilaya of Tipaza (Urban metabolism inventory).

The estimation of the urbanized area was based on two methods: the first derived from the
data describing the housing stock of the two wilayas and the second from satellite images by
the supervised classification method using satellite images from 2015. However, the second
method considers all the infrastructures (industrial, commercial, other) of each wilaya,
