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 OverviewSand steenbras - Eastern Levant Sea 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 Striped seabream is common in the Mediterranean Sea. It is a demersal species that inhabits rocky and sandy bottoms down to 80 m of depth (in the Mediterranean). It is highly appreciated and constitutes an important catch for coastal fisheries, especially along the Lebanese coast. There is no basic biological information that will aid in the sustainable management of this exploited fish stock. Fishery Indicators Type | Measure | Value | Unit | Time period |

Bio Assess Data Landing data were collected from the Ministry of Agriculture and biological data were collected from fisheries by the National Center for Marine Sciences of the Lebanese National Council for Scientific Research every month of 2015 to 2019 in the framework of the EastMed project of the FAO. The growth parameters, WLR and L50 were estimated using the biological data from the National Centre for Marine Sciences. Age frequency distributions were estimated by age-length slicing using Von Bertalanffy growth parameters after raising to the total landings. Natural mortality was estimated using the PRODBIOM spreadsheet. Assess Models Type: Age-structured VIT in addition to LBSPR and LIME Stock assessment using VPA method was performed using VIT. Y/R analyses were implemented and F0.1 and Fcurrent were estimated. Sci Advice Reduce fishing mortality. Sources FAO. 2021. General Fisheries Commission for the Mediterranean (GFCM).
