| Main Descriptors | Considered a single stock: Yes
Spatial Scale: Sub-Regional
|
| Considered a single stock: A group of individuals in a species occupying a well defined spatial range independent of other stocks of the same species. It can be affected by random dispersal movements and directed migrations due to seasonal or reproductive activity. |
| Spatial Scale: Spatial scale contains a standard term such as Global, Regional (e.g. for the whole Atlantic), sub-regional (e.g. for a part of the Atlantic), national, local (for sub-national levels). |
| Considered a management unit: An aquatic resource or fishery is
declared as [Fishery] Management Unit if it is
effectively the focus for the application of selected
management methods and measures, within the broader
framework of a management system. According to the FAO
Glossary for Responsible Fishing, "a Fishery Management
Unit (FMU) is a fishery or a portion of a fishery
identified in a Fishery Management Plan (FMP) relevant
to the FMP's management objectives." FMU's may be
organised around fisheries biological, geographic,
economic, technical, social or ecological dimensions ,
and the makeup and attribute of a fishery management
unit depends mainly on the FMP's management
objectives. |
| Jurisdictional distribution: Jurisdictional qualifier (e.g.
"shared", "shared - highly migratory") of the aquatic
resource related with its spatial distribution. |
| Environmental group: Classification of the aquatic
resource according to the environmental group (e.g.
pelagic invertebrate, or demersal fish) to which the
species belong. |
| | | | | | Habitat and Biology Climatic zone: Temperate. Horizontal distribution: Neritic. Vertical distribution: Pelagic.

The following area codes have been found as intersecting the distribution of Anchovy - Northern Alboran Resource Structure Considered a single stock: Yes Exploitation The annual landings of anchovy ( Engraulis encrasicolus) in the Northern Alboran Sea for the
last fifteen years ranged between 0.2 and 3000 tons. Anchovy was the species with the highest
economical value.
Málaga Bay is the most important recruitment and fishery area. Only this area, which represents 85% of
total landings, has been considered. Assessment Assessment Model Acoustic surveys and commercial landings and CPUEs. Overall Assessment Results During the period from 1990-2005, the anchovy stock of the Alboran showed great fluctuations in the catch. A successful recruitment as estimated by echo-acoustic tracking was observed during 2001 in the
Alboran Sea (13210 tons) producing a strong increment of landings in 2002, besides to an increase of
CPUE. Nevertheless, the catch dropped in 2003 and 2004 and 2005 it has continued at low
level (700 tons ) . This decline is consistent with the echo-acoustic evaluation (550 tons in 2003,
2013 tons in 2004 and 1921 tons in 2005). Scientific Advice - Not to increase the actual level of fishing effort
- Length at first capture should not be less than length at first maturity, and adjust
minimum legal size accordingly.
- Monitoring of the stock should be continued.
Biological State and Trend Low levels of biomass, recruitment and catch from 2003 to 2005. Source of information “Anchovy (Engraulis encrasicolus) stock assessment in GSA 01 (Northern Alboran Sea).
