Abalone farming in South Africa: an overview with perspectives on kelp resources, abalone feed, potential for on-farm seaweed production and socio-economic importance
Troella, M. D.; Robertson-Andersson, Deborah; Anderson, Robert J.; Bolton, John J.; Maneveldt, Gavin; Halling, C.; Probyn, T. (Elsevier, 2006)The South African abalone cultivation industry has developed rapidly and is now the largest producer outside Asia. With a rapid decline in wild abalone fisheries, farming now dominates the abalone export market in South ... -
Abundance and species composition of non-geniculate coralline red algae epiphytic on the South African populations of the rocky shore seagrass Thalassodendron leptocaule M.C. Duarte, Bandeira & Romeiras
Browne, Catherine M.; Maneveldt, Gavin; Bolton, John J.; Anderson, Robert J. (Elsevier, 2013)Seagrasses support a great diversity of epiphytic organisms and new research has shown that non-geniculate coralline red algae are important occupiers of space on the fronds of seagrasses. Except for a few scant records, ... -
Rapid assessment of tissue nitrogen in cultivated Gracilaria gracilis (Rhodophyta) and Ulva lactuca (Chlorophyta)
Robertson-Andersson, Deborah; Wilson, D.T.; Bolton, John J.; Anderson, Robert J.; Maneveldt, Gavin (NISC, 2009)Tissue nitrogen content and thallus colour were quantified using a rapid assessment method based on the Pantone® matt uncoated formula guide for raft-cultivated Gracilaria gracilis Steentoft Irvine et Farnham at Saldanha ... -
Seaweeds in two oceans: beta-diversity
Smit, Albertus J.; Bolton, John J.; Anderson, Robert J. (Frontiers Media, 2017)Several species assembly mechanisms have been proposed to structure ecological communities. We assess the biogeography of seaweeds along 2,900 km of South Africa’s coastline in relation to a thermal gradient produced by ... -
South African seaweed aquaculture: A sustainable development example for other African coastal countries
Amosu, Albert O.; Robertson-Andersson, Deborah; Maneveldt, Gavin; Anderson, Robert J.; Bolton, John J. (Academic Journals, 2013)The green seaweed Ulva is one of South Africa's most important aquaculture products, constituting an important feed source particularly for abalone (Haliotis midae L.), and utilized as a bioremediation tool and other ... -
Sublittoral seaweed communities on natural and artificial substrata in a high-latitude coral community in South Africa
Gersun, L.; Anderson, Robert J.; Hart, J.R.; Maneveldt, G.W.; Bolton, John J. (National Inquiry Services Centre (NISC), 2016)Coral mortality may result in macroalgal proliferation or a phase shift into an alga dominated state. Subtidal, high-latitude western Indian Ocean coral communities at Sodwana Bay on the KwaZulu-Natal coast, South Africa, ...
