Project financed by IRD and project partners
Coordinator: Pierre Fréon, IRD
Location: Peru
Duration: 4 years (01.2010 - 12-2013)
Theme: Environmental and socio-economic
assessment of major international supply
chains consuming Peruvian anchoveta
(aligned to WP5 DISCOH)
• Outputs:
– Sustainability assessment
– Policy and sustainability suggestions
– PhD thesis (plus other theses)

To compare feed ingredients,
feed formulations and seafood
products:
Gross energy content (MJ/kg)
Edible protein Energy Return
On Investment (%)
Biotic Resource Use (g C/kg)
Ecological Footprint (ha/t)
To compare intermediate and
final seafood products, and
competing supply chains:

LCAs carried out
• Two fishmeal plants:
– a conventional one producing
only Fair Average Quality (FAQ)
fishmeal and using mainly
heavy fuel as energy source
– a more modern steam plant
producing both FAQ and prime
quality fishmeal and using both
heavy fuel and natural gas
• Detailed inventories of
industrial anchoveta fleet
under processing
– preliminary LCA of
representative “average“ 395
m3 vessel category
• Two aquafeed plants (Iquitos)
– A pilot facility and a working
commercial facility
• One aquaculture farm
(Iquitos)
– Peruvian Amazonian species

Iquitos Colossoma farm
• Colossoma macropomum (Gamitana), a large Amazonian fish
• Farm: 30 ha, converted from rain forest, 11.2 ha of ponds (no
wastewater treatment), production: 100 t/a, feed: 150 t/a

Iquitos Aquafeed plants
• 2 plants visited:
– 30 t/a IIAP plant
– 8 t/m commercial plant (competing with Purina, etc.)
• < 6% Peruvian fishmeal content in feeds
• > 33% Bolivian soymeal content
• > 45% local cornmeal content

Aquafeed plant use phase
• Impact contributors in use phase:
– oil-powered electricity
– feed ingredients, mainly Bolivian soymeal (due to clearcutting in Bolivia)

Design remarks
• Key aquaculture products haven’t been characterised
for Peruvian conditions
– E.g. Peruvian rice and corn.
– Proxies were used and adaptations introduced when
possible (e.g. Bolivian soymeal adapted from Brazilian)
• Key industrial products haven’t been characterised,
yet it’s composition is known/estimated
– E.g. electric and combustion engines
19
LCA results
• Construction and maintenance of (reduction, feed)
plants contributes negligibly
• Fuel use is the main contributor to impacts in all
activities (fishing, reduction, feed processing)
• Feed provision is the main contributor to impacts in
extensive Peruvian aquaculture
• The sourcing of feed ingredients is a critical factor for
associated environmental impacts of feeds
– E.g. Brazilian soymeal performing much worst than
Bolivian one, due to clear cutting of rain forest vs. of
shrublands.

Further (ongoing) work
• EwE scenarios definition and integration with Umberto
• Selection of and data gathering for socio-economic
indicators
• Statistical processing of fleet inventories and
comprehensive LCA of fleet categories
• Further LCAs:
– Canning, curing and freezing plants
– Carnivore fish and shrimp aquaculture farms
• Gathering supply chains operative data and LCIs
– Background processes for provision of feed ingredients
– Published LCI/LCA data must be recalculated to ensure
consistency
