| Main Descriptors | Considered a single stock: No
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. Bottom type: Unspecified. Depth zone: Unspecified. Horizontal distribution: Neritic. Vertical distribution: Pelagic.

The following area codes have been found as intersecting the distribution of Anchovy - Western part of South Adriatic Sea Resource Structure Considered a single stock: No Exploitation Information on Operational Units exploiting this resource will be soon available at the following link: GAS18 Western Part Anchovy (Engraulis encrasicolus)Assessment Data The annual echosurvey was performed in the summer season 2006 covering the western part of GSA 18. Pelagic biomass estimates, as a whole and per anchovies and sardines, were analyzed. Assessment Model Type: Others Overall Assessment Results In this area there was an increase in biomass in the last year. Trends of the western GSA 18 (from Vieste to Brindisi, historical surveys since 1987) show an abundance level similar to that of the years 1997-2002 for total pelagic biomass after the fall of the years 2003-05; this result is mainly due to the anchovy stock that has come back to the abundance level of 5-10 years ago. The results of the studies of small pelagic populations derived from the historical surveys in the western Adriatic Sea show that these populations are affected by large variability in time and space. This variability is mostly due to environmental factors and this is why an effort is currently in progress to find possible relations between abundance estimates and oceanographic parameters. Even if anchovy (both in Northern and Southern Adriatic) and sprat stock (in Northern Adriatic) showed good levels of abundance in 2006 survey they have just recovered from a previous worse condition; moreover sardine stock still shows a low level of abundance that is going on with continuity since 1998. Scientific Advice For management considerations- It is reasonable not to increase the actual level of fishing effort on small pelagic fish
- SCSA endorsed the WG management advice and recommendations on anchovy (Engraulis encrasicolus) in GSA18.
For researchFishery data should be collected Management Management Advice Scientific advices for management consideration formulated by SCSA have been adopted by SAC. Biological State and Trend Exploitation state: UncertainAbundance level: estimated biomass at 189332 tons For Stock abundance, the large variability in time and space is mostly attributable to environmental factors.
