EXECUTIVE SUMMARY SKJSKJ-Figure 7. Number of 1° x 1° squares with catch of skipjack for the purse seiners operating in the easternAtlantic (1969-2007). The significant increase observed since 1991 could be due in part to a modification of thespecies composition correction procedure implemented at this date.SKJ-Figure 8. Estimation of the mean weight of the skipjack landed, by major fishery, in the eastern Atlantic(1969-2006). Given the fishing mode in which Ghanaian baitboats and purse seiners collaborate they wereestimated as a combined fishery.49
ICCAT <strong>REPORT</strong> 2008-2009 (I)Total mortality based on length frequencyZ index0.5 1.0 1.5 2.0 2.5 3.0YFTBETSKJ_ESKJ_W1970 1980 1990 2000YearsSKJ-Figure 9. Changes over the years in the apparent total mortality Z , based on Beverton and Holt’s equation,for the three tropical tuna species in the Atlantic Ocean. YFT = yellowfin, BET = bigeye, SKJ E = Easternskipjack, SKJ W = Western skipjack. Z is calculated as Z = K*( L∞ -L moy) / (L moy - L c), with L∞ and Krepresenting the parameters of the von Bertalanffy growth equation, Lc = the length at which the fish are fullyrecruited (fixed here at 50 cm), and Lmoy the medium length of fishes fully recruited (Beverton and Holt, 1956).SKJ-Figure 10. Distribution of released SKJ (left panel) and apparent movement from recoveries (right panel).On the basis of current knowledge, there are few recoveries in the West.50
