Title

Selection of marine macroalgae for nutrient biofilter and bioproduct trials in the coastal waters of Queensland, Australia

Abstract

The capacity of many macroalgae to rapidly absorb soluble inorganic nutrients and convert them into primary biomass provides opportunities for their use in the bioremediation of nutrient-enriched waters. Marine-based macroalgal cultivation has the potential to target difuse source nutrient discharges and produce valuable bioproducts such as fertiliser, soil conditioning agents and agricultural feed additives and phycocolloids. Whilst macroalgal diversity ofers benefts for improving and maintaining healthy marine ecosystems, it also presents a challenge for determining the best candidate species for cultivation as a nutrient bioflter and, ultimately, a source of bioproducts. We developed and applied a multi-criteria selection model to identify likely candidate macroalgal species for cultivation in Queens?land’s coastal waters for biofltration and bioproduct development, focusing on native spe?cies and product development for the agronomical and horticultural sectors. From a spe?cies database of 1380 macroalgal species, candidates were initially selected based on their regional abundance, distribution and morphological characteristics considered amenable to in-situ cultivation and harvesting. From a resulting shortlist of 17 species, fve systematic literature searches were applied to identify bioflter potential, bioproduct potential and cur?rent cultivation status. Of the shortlisted species, Ulva lactuca, Gracilaria edulis and Hyp?nea cervicornis ranked most highly in the multi-criteria analysis, with several other species showing good potential, but requiring further investment in understanding key biological processes and the development of cultivation protocols.
