Researchers from Spain are working on sustainable alternatives for the aquaculture sector to help enable producers to replace commercial oxygen with renewable energy, said the Centro Tecnológico de Acuicultura de Andalucía (The Aquaculture Technology Center of Adalucia) on Tuesday.

The energy savings due to eco-efficient systems designed for the aquaculture sector can save up to 30 percent of energy consumption, the group said.

The researchers are collaborating on the LIFE AQUASEF project, spurred by the fact that 45 percent of aquaculture sites are "far from urban centers, mainly located in highly valued natural areas without access to the grid, [which] forces them to increase their consumption and their expenses almost fivefold in comparison with aquaculture facilities better connected."
