In a demonstration of its growing marine research capabilities, Angola’s National Institute for Fisheries and Marine Research (INIPM), supported by the AIR Centre, has unveiled crucial insights into the dynamics affecting sardinella populations along the Angolan coast. Once boasting abundance levels of around 200,000 tons, sardinella fishing has been a cornerstone of Angola’s economy and food security, providing essential protein for countless families.
INIPM researchers uncovered the complex relationship between climate factors and fishing pressure affecting sardinella populations. This study identified key geographical challenges, including unfavorable coastal bathymetry that impacts egg and larvae retention. The investigation highlights discoveries regarding recruitment patterns in the south of Tombwa. It also demonstrates that successful sardinella recruitment depends heavily on strong upwelling phenomena and relatively cold South Atlantic summer conditions, especially in the tropical upwelling region between Soyo and Baía Farta.
This comprehensive study of environmental factors, including climate change, unsustainable fishing practices, and ecological balance, and their impact on sardinella populations represents a significant step forward in sustainable fisheries management. Member of the AIR Centre network since October 2021, INIPM continues to demonstrate its growing expertise in marine research and its commitment to securing Angola’s maritime resources for future generations.
