Abstract

The influence of light and culture media on the growth of the red seaweed Gracilaria gracilis (Rhodophyta, Gracilariales) under laboratory conditions

Highlights

  • Seaweed culture systems worldwide aim to achieve high biomass production and profitable yields, by adopting methodologies designed for a target species

  • G. gracilis presented a distinct behaviour according to (1) the type of container, (2) the chosen nutritional media, and (3) the distinct light sources and intensities studied, growing well in seawater supplied with VSE medium, whereas individuals placed in F/2 or Complesal medium died within the first and second week of assays, respectively

  • Nutrient demands that come with increasing growth rates must be considered, to manipulate G. gracilis biomass growth while keeping an economically feasible culture system
