Land-based seaweed cultivation creates darker, less predictable light environments

Abstract
Humans modify the habitats of cultured species to maximise productivity, creating conditions distinct from those in which those species originally evolved. These human-altered environments impose strong selection pressures that favour novel phenotypes. While instances of deliberate selection for favoured phenotypes are ubiquitous, the consequences of unintentional selection regimes associated with culture conditions are less well understood. With their high stocking densities and circulating nature, land-based seaweed cultures are likely to generate light regimes that are vastly different from those of the natural environment, but explicit tests are lacking. Here, we quantified how light environments experienced by seaweed in land-based culture tanks differ from those of the natural environment. We found significant differences in culture and natural light environments. Cultures were usually much darker, but occasionally much brighter and the light regimes were less predictable than those occurring in the natural environment. Our results highlight that in our system, land-based seaweed cultures generated light regimes unlike anything in nature and this likely presents challenges for seaweed adaptation and scaling up of production.
