What Is In News
• Most aquaculture systems
have not achieved the levels
of efficiency as seen in
terrestrial food production
systems. Blue foods can be
made more environmentally
sustainable.
• Greenhouse gas emissions for
capture fisheries such as
sardines and cod are low,
according to a new study.
What Is Blue Food
• They are food derived from aquatic
or marine animals, plants or algae
that are caught or cultivated in
freshwater and marine
environments.
• Examples
• Seaweeds, Sea Cucumber
• Bivalves (mussels, oysters, etc.)
• Fishes like tilapia, salmon, catfish
and carp, etc.
• It includes both Capture and Culture
Fishery
Reports - Environmental performance of blue foods
• Environmental performance of blue foods
• Most aquaculture systems have not
achieved the levels of efficiency seen in
terrestrial food production systems
• The report is a part of the Blue Food
Assessment (BFA). The BFA is a
collaboration between
• Sweden based Stockholm Resilience
Centre
• United States-based Stanford
University
• The non-profit EAT.
Key Findings
• Across the range of blue foods farmed sea
weeds and bivalves like mussels generate the
lowest GHG.
• Flatfish and Lobsters generate the highest GHG.
• Farmed Salmon, Trout, Carp, perform similar or
better than chicken in GHG emissions
• Considerable opportunities exist in further
optimizing the environmental performance of
blue food
• Efficiency of aquaculture feed
• Reducing fuel use by optimizing the fishing
gear
Benefits Of Blue Food
• High Nutritional Benefits
• They have higher nutritional benefits in comparison to terrestrial food. They
are rich in important nutrients like omega-3 fatty acids, vitamins and
minerals.
• Ecological benefits and environmental footprints
• They are more sustainable as they release less greenhouse gasses.
• On average, the major species produced in aquaculture were found to have
lower environmental footprints comparable to terrestrial meat.
• Less pressure on Land
• Cultivation pressure is transferred from land to water
• Food Security
• Can feed the masses by solving both the problem of
• Real Hunger
• Hidden Hunger
Challenges To Blue Food
• Acceptance Of Blue Food
• The acceptance of many sea foods like sea
cucumber, octopus, starfish etc. is less.
• It needs a behavioural change in dietary habits.
• Technology and Capital Intensive sector
• One of the major challenges with blue food is
the need for high end technology and capital.
• Lack of skilled labour and resources
• Danger of invasive species
• There may be a threat of invasive species E.g.
Tilapia Fish imported from Africa is now
invasive.
