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. |

Water Area OverviewDeep-water rose shrimp - Northern Spain Aq Res Struct Biological Stock: No 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] Exploit Deep-water rose shrimp is exploited by bottom trawlers. This fishery is developed along the deep continental shelf targeting hake and crustaceans. Vessel length was between 12–24 m. The number of harbours with deep-water rose shrimp landings is 25 for the whole area, and the number of vessels in this area is 354 for the last year (2019). Total landings in GSA 6 (2001–2019) were around 4 784 tonnes and 328 572 days. In 2019, landings were around 704 tonnes and total effort over 33 385 fishing days by year and CPUE medium, 21.1 kg/day. Discards of deep-water rose shrimp are negligible. Fishery Indicators Type | Measure | Value | Unit | Time period |

Bio Assess Data Data used include size composition of commercial trawl catches, official landings and data from MEDITS surveys (2001-2019). Biological parameters were obtained from studies carried out in the area: growth from Guijarro et al. (2009) and length-weight relationship and maturity ogive from the DCF; M vector calculated from PRODBIOM. (Abella et al., 1997). Assess Models Type: Age-structured XSA XSA (FLR), FLBRP package was used for Y/R analysis and Flash package for the short-term forecast. This is a revised assessment. The assessment is based on the previous year but with minor model setting changes and indexes used. Results Recruitment, SSB and landings showed the highest values at the beginning and particularly at the end of the data series (2001-2019), with very low values in the intermediate years. Historical data showed that catches of this species are usually low. Both recruitment and SSB showed minimum values from 2004 to 2008. Fishing mortality showed an increasing trend in last four years.
