On the Jamestown quays, nets are piled up, mended and loaded back into the pirogues. In Ghana, landings of small pelagic fish fell by 59% between 1993 and 2019, despite increased fishing effort. Landings of Sardinella aurita, a favoured species, dropped from 119,000 tonnes in 1992 to 11,834 tonnes in 2019. Over the same period, the artisanal fleet grew from about 8,000 canoes in 1990 to 13,650 in 2017. According to an analysis published in The Conversation in 2024, the causes put forward are warming waters, industrial trawlers, and the growing number of canoes, with their larger nets and more numerous engines.
