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.

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.
