reported significantly
lower growth rates for hybrid abalone (H. laevigata × Haliotis
rubra) fed a formulated diet, compared to abalone fed freshmacroalgae
(Ulva spp. and Grateloupia spp.). Further research is required to investigate
the growth and feed utilisation of abalone fed fresh macroalgae and
commercial diets. In this study,we aimed to: (i) investigate the effect of
nutrient enrichment (non-enriched and enriched) and macroalgae type
(Ulva sp., Gracilaria cliftonii and an equal mix of Ulva sp. and G. cliftonii)
on growth performance and feed utilisation of greenlip abalone; and (ii)
compare the growth performance and feed utilisation of abalone fed
fresh macroalgae to those separately fed either one of the three commercial
formulated diets.
