Climate change is modifying fish distributions [6] and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. [7] The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector.
Climate change is modifying fish distribution [25] and the productivity of marine and freshwater species. This reduces sustainable catch levels across many habitats, puts pressure on resources needed for aquaculture , on the communities that depend on fisheries, and on the oceans' ability to capture and store carbon ( biological pump ).
"Fish cages should be moved further from the coast, and more research and development of offshore cage technology must be promoted to this end. Experience from outside the aquaculture sector, e.g. with oil platforms, may well feed into the aquaculture equipment sector, allowing for savings in the development costs of technologies."
Climate change will accelerate the prevalence of pests and diseases and increase the occurrence of highly impactful events. [42] The impacts of climate change on agricultural production in Africa will have serious implications for food security and livelihoods. Between 2014 and 2018, Africa had the highest levels of food insecurity in the world ...
Due to the limited availability of fish seed, carp has fallen out of favour, and North African catfish, along with Nile tilapia, has taken its place. Although fish farming in Uganda has so far been pond- and subsistence-based, the growing interest in commercial aquaculture is providing an impetus towards cage-culture based aquaculture.
However, climate change may preempt this FAO scenario as a study by the International Union of Forest Research Organizations in 2009 concluded that the stress of a 2.5 °C (36.5 °F) temperature rise above pre-industrial levels could result in the release of vast amounts of carbon [21] so the potential of forests to act as carbon "sinks" is "at ...
For the most recent several decades, the political goals in fisheries management of commercially important species have been rapidly evolving, primarily driven by (1) a recognition of the response of fish and other target animals to changing climate, (2) new technologies for fishing particularly on the high seas, (3) development of competing ...
However, species originally from Africa have been widely introduced and have become economically important as food fish in many countries. China, the Philippines, Taiwan , Indonesia, and Thailand are the leading suppliers, and these countries altogether produced about 1.1 million metric tons (1.1 × 10 ^ 6 long tons) of fish in 2001 ...
