Utilising microalgal mixotrophy to maximise larval nutrition
The aquaculture of the mussel species Mytilus edulis produces approximately 7000 tonnes of biomass in 2015.
While mussel aquaculture is theoretically a low carbon, sustainable source of protein, the ability to upscale these production of mussels in Scotland is limited by the supply of wild mussel larvae.
To expand production it is necessary to create a mussel larval hatchery. To create this hatchery the costs of production must be brought down before such a hatchery can be economically viable. As microalgal production may represent 40% of the costs of a larval hatchery it is necessary to reduce this cost.
Mixotrophy is the ability of microalgae to be cultured with a carbon source, an alternative to use of light alone. This may be a method of reducing the costs of production of microalgae sustainably, however, more work is needed prior to mixotrophic production of aquaculture relevant microalgal species.
