This milestone report contains an update on the analysis of Yellowfin tuna (YFT) bioclimatic modelling as well as the synthesis based on D12.2 and MS42. Local Yellowfin tuna (Thunnus albacares, YFT) catch rates covering the area 10-20°N latitude and 10-30°W longitude were analysed to indicate catch opportunities in Cape Verde waters. Local catch-per-unit-effort (CPUEl) is treated as a function of stock size, Ns, and environmental factors, Vi, the latter at local scale or at stock scale in terms of climate indices. Of the two indices applied to indicate stock size, i.e. the Japanese long line stock index (LLindex) and the so-called Index4 series, the LLindex.
