The impact of Climate Change (CC) on all aspects of human activity has been at the
forefront of political, social and intellectual debate for many years.The impact of CC on
marine and freshwater capture fisheries has wide implications but in terms of the food fish
capture fishery the main effect will be on fish populations and distribution . Aquaculture, being
a controlled environment, may be better placed to adapt to Climate Change but where open
ponds or marine environments are used the effects of Climate Change on water characteristics
such as acidification oxygen availability, temperature, salinity and sea level must be
addressed.Other impacts could be through changes in monsoon rain patterns and the impact of
disease under new climatic conditions. Responses to Climate Change must of course always
take into account the socio-economic importance of capture fisheries and aquaculture which
provide livelihoods, income and food for very many people .The impact of Climate Change
(CC) on all aspects of human activity has been at the forefront of political, social and
intellectual debate for many years. The impact of CC on marine and freshwater capture
fisheries has wide implications but in terms of the food fish capture fishery the main effect will
be on fish populations and distribution . Climate change is a defining challenge for the global
aquaculture sector, primarily because its production depends heavily on the biophysical
conditions of aquatic environments. As the world’s fastest-growing food production system,
aquaculture now provides over 50% of the global fish supply for human consumption.
However, shifting climatic patterns are disrupting this stability, threatening the food
security and livelihoods of billions, particularly in developing regions like Asia, which
accounts for over 90% of global production.

Outcome:
The key outcomes regarding the impact of climate change on aquaculture emphasize that
while the sector is growing, negative effects currently outweigh the positive ones,
necessitating urgent, climate-resilient adaptations. Climate change will have indirect impacts
on aquaculture through changes in fisheries, which provide inputs such as feed and seed.
These impacts will affect the suitability of areas for aquaculture species, the availability and
prices of resources like fish protein for fish feed, and the production of aquafeed. The
availability and prices of fishmeal and fish oil, key ingredients in aquafeed, will be affected
by climate-driven changes in fisheries.Additionally, the increasing diversion of plant
materials for biofuel production may lead to limited availability and high costs of aquafeed
ingredients.
