AQUASEFECO-EFFICIENT TECHNOLOGIES DEVELOPMENT FOR

ENVIRONMENTAL IMPROVEMENT OF AQUACULTURE

The greatest challenge facing mankind is to feed 9,600 million people who inhabit the planet earth by 2050.1

Around 795 million people worldwide do not have enough food to lead a healthy and active life. That's almost one of every nine people on earth.

2

In this situation, productive models require new approaches (leverage resources that 3/4 of the planet is water)3

Aquaculture context





A very significant increase is expected foraquaculture

Global Fish Production:Data and projections 1984-2030

AverageAnnual Rate

of 3,2%

Besides that 70% of the

planet's surface is water,

aquatic animals are more

efficient converters of their

food that terrestrial

vertebrates and their

reproductive rates are several

orders of magnitude higher

than that of these.

AQUASEFMEJORA AMBIENTAL DE LA ACTIVIDAD ACUÍCOLA A TRAVÉS

DEL DESARROLLO DE TECNOLOGÍAS ECO-EFICIENTES

Easily replicated in almost 95% cases

The potential for energy improvement of aquaculture facilities is high

01

02

Assess the current land use and

natural resources where indigenous

aquaculture plant is located



Only 37,5% renewable energy usage in aquaculture

Energy Consumption≈30% energy savings

≈10% energy supply by renewable energy

Main impacts in

aquaculture sector

Water Consumption- Improve water quality by cultivation of microalgae

Fishmeal Consumption- Nutritional complement by cultivation of

microalgae

Eutrophication- Fixing CO2 by cultivation of

microalgae
