| 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: Littoral; Neritic. Vertical distribution: Pelagic.

The following area codes have been found as intersecting the distribution of Sardine - Northern Alboran Resource Structure Considered a single stock: Yes Exploitation Sardine ( Sardina pilchardus) and anchovy ( Engraulis encrasicolus) are the main target species of the purse seine fleet in Northern Alboran GSA01, but other species with lower economical importance are also captured, sometimes representing a high percentage of the capture: horse mackerel ( Trachurus spp.), mackerel ( Scomber spp.), frigate mackerel ( Auxis rochei), Atlantic saury ( Scomberesox saurus) and gilt sardine ( Sardinella aurita).
This fact sheet is exclusively focused on fishery of sardine. Information on Operational Units exploiting this resource will be soon available at the following link: GSA 01 Sardine (Sardina pilchardus)Assessment Data Data used:
Landings from 2000-2008 from all Fishery ports from GSA01.
ALK 2003-2008, combined ALK for 2000-2002. Length Distributions 2003-2008, combined for 2000-2002.
Biological sampling 2003-2008 for Maturity at age and Weight-Length relationships.
Tuning data from acoustic survey ECOMED and Commercial Fleet off Estepona, Málaga and Adra for years 2003 to 2008. Assessment Model Type: Age-structured Virtual population analysis (VPA), Extended survivors analysis (XSA) VPA Lowestoft software suite was used and XSA was the assessment method. A separable VPA was also run as exploratory analysis for both stocks. Stochastic short term projections were also produced Scientific Advice For management considerationsRegarding suggestion for management options, this fishery is considered overexploited.Although the exploitation rate (fishing mortality) is at a moderate level, the stock abundance in 2008 remains at low levels (the lowest of the time series 2002-2008) and continues the decreasing trend observed from 2005 onwards. Unless the recruitment levels increase in the near future, this fishery will be being exploited at above a level which is believed to be sustainable in the long term, with no potential room for further expansion and a higher risk of stock depletion/collapse. The use of BRP is also recommended to be used. However based to the examined data, sardine was considered as fully exploited with risk to overexploitation. Management Management Advice Advices and comments by SACScientific advices for management consideration formulated by SCSA have been adopted by SAC. Other comment: Not increase fishing effort. Biological State and Trend Exploitation state: OverexploitedExploitation rate: Moderate fishing mortality
Abundance level: Low abundance No reference points for sardine can be suggested at this point.Further years will come a Time series extension suitable to suggest relevant Reference Points as well as Harvest Control Rules for this fishery.
