SCIENTIFIC NAME(s)

Sardinella aurita

SPECIES NAME(s)

Round sardinella, False sardine, Spanish sardine

COMMON NAMES

bang, black sprat, false sardine, allache, tayit, sardalya

Round sardinella, Sardinella aurita, occurring off the coasts of Morocco, Mauritania, and Senegal are considered to be largely migratory throughout the West African region, though studies have indicated the existence of stationary sub-groups; and there is evidence of a Moroccan S. aurita component that is genetically isolated from S. aurita in Mauritanian-Senegalese waters  (Food and Agriculture Organization of the United Nations 2001; Bacha et al. 2016) .  A five year initiative (2014-2019) is currently underway to define the genetic background of S. aurita and S. maderensis between Morocco and Namibia (FAO 2016; Coastal Resources Center 2017) . Meanwhile, for assessment purposes, the FAO considers a single stock unit ranging from south of Senegal to Morocco's northern border (Casey et al. 2014 ; FAO 2016) . 

Round sardinella are exploited in artisanal and industrial small pelagic fisheries of Morocco, Mauritania, Senegal and Gambia.  Together with Madeiran sardinella (S. maderensis) and Bonga shad (Ethmalosa fimbriata), they are the primary source of feed for the fishmeal industry in Mauritania (FAO 2016) .

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

SELECT SCORES

MANAGEMENT QUALITY

Different components of this assessment unit score differently at the fishery level. Please look at the individual fisheries using the selection drop down above.

As calculated for 2017 data.

The score is ≥ 6.

There are no harvest control rules defined in regulation nor established at the management level. Management measures are neither species nor stock specific. Regulations such as fishing licenses, technical measures and closed areas are in place for both Moroccan and Mauritanian multispecies pelagic fisheries. There is a management plan since 2010 for the Moroccan multi-species fishery operating in zone C with a Total Allowable Catch but no harvest control rule is known to be in place (Gascoigne 2014a,b; 2016). For Mauritania, catch limits are defined under the Fisheries Partnership Agreement between the European Union-Mauritania (2015-2019; EU 2015) and a management plan was reportedly still under development as of 2015 (FAO 2016b); but the strategy applied to the fishery is not known. Senegal and Gambia both have rules specifying access to fisheries, but no management plans are effectively in place (Corten et al. 2012).

As calculated for 2017 data.

The score is < 6.

There are a number of catch quotas established for various components of the fishery in Morocco and Mauritania (CSC 2016; EC 2016; Gascoigne 2017); but they do not correspond in a meaningful way with advised catches, and it is not clear how or to what degree they are informed by stock assessment, and to what extent they control harvests. Advice on catches is given for the region (FAO 2016b), but there are no regional harvest limits and little coordinated effort to implement management measures at the regional scale (Corten et a.. 2012). Further, while advised catches are specific to sardinella spp (typically S. aurita and S. maderensis combined), management quotas are for all small pelagics combined. In recent years, the FAO have given no catch recommendations, due to data limitations, components. There appears to have been little response by management in regard to this advice given that certain sectors of the fishery have undergone significant unchecked expansion, and permitted catches have not been significantly reduced (FAO 2016). Finally, while it is appropriate to focus advise at the regional scale given the largely migratory population in the fishery; there are sedentary sub-components that may be overexploited without a local management strategy (FAO 2001; Bacha et al. 2016).

As calculated for 2017 data.

The score is < 6.

Fisher compliance with catch limits cannot be meaningfully assessed because quotas and advice are misaligned. Illegal, unreported and unregulated (IUU) is a significant concern in West Africa (Belhabib et al. 2013; Standing 2017), and has been flagged as a particular problem for sardinella fisheries (FAO 2016a). Foreign-flagged vessels and various access agreements create transparency issues, and inadequate surveillance and monitoring exacerbates this problem (Standing 2017; Belhabib 2013). Discarding information at the regional level is limited, but preliminary studies indicate that discarding in Moroccan fisheries is low (Gascoigne 2017).

STOCK HEALTH:

As calculated for 2017 data.

The score is < 6.

For 2015, the stock was assessed using length frequency data from catches sampled during 2012-2014, with a length cohort (LCA) model and yield per recruit analysis to estimate fishing mortality (FAO 2016b). The result indicated fishing mortality (F) to be 250% of the reference point (F = F0.1), reflecting an overexploited status for the S. aurita stock. Application of a catch curve analysis supported this result. The Working Group warned that increased catches do not necessarily reflect the state of the stock, and it is still at risk. Due to lack of adequate abundance data, projections of future recruitment were not possible.

DATA NOTES

1) Assessment of sardinella has been hampered by lack of abundance indices (FAO Fisheries &#38; Aquaculture 2016) . There is insufficient information to make a stock status determination, so the related score, "Current Health", cannot be assigned via quantitative or qualitative method.
