For the assessments of black hake in Mauritania, total catch and abundance indices of Spanish trawlers targeting fresh hake were used. The CPUE series of this fleet was used as abundance index since it is the most complete and representative of the resource abundance. Although these data cover the whole period 1983-2012, the latest years from 2000 to 2012 are representative of the new fishing strategy period.Two assessment tests were carried out with the global model for the Mauritanian zone:<br/> - A first test with the total catch and CPUE abundance indices from 1983 to 2012. To fit this long data series to the models, the environmental effect was taken into account.<br/> - A second test with the latest total catch and CPUE abundance indices from 2000 to 2012, considering the most recent fishing strategy. No environmental effect was used. The parameters used were r= 0.50 per year, K=50 000 tonnes and BI/K=30 percent.<br/>

Data on length structure collected by the IEO teams from landings of hake vessels in 1991–2012 were available. However, in view of several uncertainties about the middle of the series (this is explained in the 2010 WG), only the 2004-2012 data were used to run the LCA analytical model (see Section 2.4.3 of FAO 2016b).
