Abstract:

An analysis is presented of the distribution and apparent relative abundance of yellowfin tuna (Thunnus albacares) in relation to thermal domes in the eastern tropical Atlantic. The distribution of catch rates of yellowfin tuna in the Japanese long-line fishery indicates that deep-swimming yellowfin are distributed around and downstream from the domes. The reason propounded in this paper is that upwelling in the domes and subsequent enrichment produce rich feeding areas for yellowfin tuna.
