Abstract Fish is an important source of animal protein for billions of people and in some tropical countries like Bangladesh, the Pacific islands, and the Maldives, fish provides more than 60% of animal protein supply. Climate change [the rise in temperatures (T°C), ocean acidification (OA), sea-level rise (SLR) and extreme events (EE)] is an additional threat and risk to world fisheries, aquaculture, and seafood security, in addition, to existing threats posed by other stressors. The T°C will have both the negative and positive effects on fisheries and aquaculture, of which, the temperate areas/countries will benefit, while the tropical regions/countries will be losers due to shifting in fish species from the tropical areas to the temperate areas to escape the warmer water. The T°C would cause coral bleaching and mortalities and may enhance seafood contamination (by algal toxins and metals). The OA would adversely affect many organisms that use calcium carbonate for their skeletons and would cause a decrease in abundance of commercially exploited seafood organisms (shellfish and finfish). SLR would cause salinisation of freshwater fisheries and aquaculture facilities and would damage or destroy many coastal ecosystems including mangroves and salt marshes, which are essential habitat for wild fish stocks. Climate change is projected to increase the frequency and intensity of EE. Besides, EE would destroy seagrass and seaweed beds and mangroves (which are important nursery areas for fishes). The economic loss and impacts on fisheries, aquaculture and seafood security due to T°C, OA, SLR, EE could be substantial in both tropical and temperate areas/countries. To achieve sustainability in fisheries and aquaculture in line with the new global sustainable development goals (2016-2030), it will be essential to identify appropriate adaptation and mitigation measures. Such measures may include promotion of climate-smart fisheries and clim
