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. |
Reference Year: The Reference Year is the last year considered in the stock assessment and/or fishery status. |
| | | | Biological State and Trend In overexploitation, with relatively low biomass. [The GFCM methodology to provide stock status and management advice is described in the Appendix F of the Sixteenth Session of the Scientific Advisory Committee Report. See the Bibliography section.] Habitat and Biology Climatic zone: Temperate. Bottom type: Soft bottom. Depth zone: Slope (200 m - 1000 m). Horizontal distribution: Neritic. Vertical distribution: Demersal/Benthic.

The following area codes have been found as intersecting the distribution of Blue and red shrimp - Northern Spain Resource Structure Considered a single stock: Yes Stock assessment in the GFCM area of application is often conducted by management units, based on GSAs. This method does not ensure that the whole stock is assessed, since stocks may cover several different management units. In some cases, when there is scientific evidence of a stock spreading through different GSAs, as well as information on species from different GSAs, existing information is combined across GSAs. This is then defined as a “joint stock assessment of a shared stock”. The GFCM recommends that when scientific evidence of shared stocks exists, joint stock assessments should be attempted. A number of activities aimed at achieving a better definition of stock boundaries are currently being conducted at the GFCM level. [The State of Mediterranean and Black Sea Fisheries, 2016] Exploitation The trawl fleets fishing efforts in the ports were quite stable for the period studied with small variations of the number of vessels in the recent years. Vessels length was between 12-24 m. The gear used corresponded to a trawl net 60 and 100 longest rope. The vertical opening was between 1-3 m. The codend mesh size used was a squared 40 mm of mesh opening. The net was rigged two doors between 500-800 kg. Trawl fleet in the four ports do daily trips with a unique haul directed to the red shrimp, with a duration between 5-7 hours. The number of harbours with red shrimp fleets is 26 for the whole area, and the number of boats in this area is 189. Discards of the red shrimp are null. In 2019, landings were around 547 tonnes and total effort over 14 251 fishing days by year and CPUE medium, 38.4 kg/day. Fishery Indicators Type | Measure | Value | Unit | Time period |

Assessment Data Size composition of commercial trawl catches by sex, official landings and data from MEDITS surveys (2000-2019). Growth parameters from L/W and Age/L relationships are from DCF (2013-2015). M vector is from ProdBiom (Abella et al 1997). Assessment Model Type: Age-structured a4a SCAA (a4a, FLR), FLBRP package for Y/R analysis and Flash package for short-term forecast. Overall Assessment Results Stock biomass showed oscillations for the entire data series, with a general decreasing trend. Recruitment is also decreasing, F increased last year with fluctuations along the time series studied. Scientific Advice Reduce fishing mortality.
