The last stock assessment completed for Eastern Atlantic Skipjack tuna was completed in 2014, and used catch data up to 2013 (ICCAT 2014b). Methods used in recent skipjack tuna stock assessments included a Catch-only model, and Bayesian Surplus Production Model (ICCAT 20014b).

The last stock assessment completed for Eastern Atlantic Skipjack tuna was completed in 2011, and used catch data up to 2010 (ICCAT 2009b, 2012b). The recent stock assessment report reveals that the skipjack tuna – Eastern Atlantic stock is healthy and current F2008/Fmsy is <1 and B2008/Bmsy is >1(ICCAT 2012). Methods used in recent skipjack tuna stock assessments include Multifan-CL model, Catch-only model, and Bayesian Surplus Production Model methods (ICCAT 2009b).
Catch data from Ghanaian tuna fleet as been used to estimate catch at size and indices of abundance for stock assessments in recent years (Kell et al., 2011).

“Complete data on fishery statistics of the artisanal fishery are estimated by extrapolation from landings sampled from harbours of each region (Ferraris, 1994). Observer’s record catches are directly reported at sea for foreign vessels and landings for national industrial vessels are recorded at Dakar harbour. Direction of Oceanography and Maritime Fisheries (DOPM) is responsible for collection and analysis of marine fisheries statistics in Senegal” (Pramod and Pitcher 2006).

There is a need to adequately quantify tuna catches from artisanal fleets along the Eastern Atlantic countries to provide more reliable stock assessment estimates.

In 2009, St Helena there was no quota allocation or catch limits for skipjack tuna (St Helena share of ICCAT quota allocated under UK overseas Territory). Carleton et al (2010).
Skipjack catches have been below 110 tonnes since 2003 in St Helena waters (Carleton et al 2010).
2005 catch (St Helena): 63 tonnes skipjack tuna
2006 catch: 88 tonnes
2007 Catch: 110 tonnes

Skipjack tuna catches for East and West Atlantic combined were about 142,200 tonnes in 2006 (115,700 tonnes from East Atlantic and 26,500 tonnes from West Atlantic) ICCAT (2009b). Skipjack tuna catches have been increasing progressively from 1950-1990, with catches increasing from 45,000 tonnes in 1970 to 98,000 tonnes in 1980, and then peaking at 186,000 tonnes in 1991, and declining to 119,000 tonnes in 2000, with catches in range of 115 -126,000 tonnes in the last decade (ICCAT 2009b, 2012).

The stock is healthy and fishing mortality is below the target level that, if maintained, will predictably hold the healthy condition of the stock.
