High spatial and temporal variation in biomass composition of the novel aquaculture target Ecklonia radiata

ABSTRACT: The biomass composition of kelp varies within species both spatially and temporally. However, this variation in biomass quality has not yet been investigated for the native kelp Ecklonia radiata within New Zealand, where the kelp is a target for the emerging seaweed aquaculture industry. In this study we quantified spatial and temporal variation in the composition of E. radiata biomass, collected from 12 sites around the North Island of New Zealand and from 12 months across a full year at a single site (n = 138). High spatial variation was detected for most components, including alginate (range: 16.6 – 22.7% DW, n = 12), fucoidan (range: 1.2 – 1.6% DW, n = 12), phlorotannins (range: 4.8 – 9.3% DW, n = 72), and glucose (range: 9.3 – 22.6% DW, n = 12).
