Integrated culture of silver kob Argyrosomus inodorus and bloodworm Arenicola loveni loveni in abalone farm effluent
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: RD Yearsley --- Department of Ichthyology and Fisheries Science, South Africa CLW Jones --- Department of Ichthyology and Fisheries Science, South Africa PJ Britz --- Department of Ichthyology and Fisheries Science, South Africa NG Vine --- Department of Ichthyology and Fisheries Science, South AfricaSouth African abalone Haliotis midae farms utilise large volumes of seawater (c. 500–1 500 l s–1) and produce relatively dilute effluents that are potentially suitable for the integrated culture of other species. To test this hypothesis, a marine finfish, silver... -
Salinity tolerance of the South African endemic amphipod Grandidierella lignorum (Amphipoda: Aoridae)
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: NF Masikane --- School of Life Sciences, South Africa BK Newman --- Coastal Systems Research Group, Natural Resources and the Environment, South Africa UM Scharler --- School of Life Sciences, South AfricaThe endemic amphipod Grandidierella lignorum is an organism potentially suited to the toxicity testing of coastal water and sediment in South Africa. The ranges of salinity and temperature at which G. lignorum can be used for toxicity testing were investigated... -
Are there long-term temporal trends of size composition and the length– weight relationship? Results for chokka squid Loligo reynaudii during the peak spawning season off the south coast of South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MR Lipiński --- , South Africa MA Mmethi --- , South Africa D Yemane --- , South Africa J Githaiga-Mwicigi --- , South Africa WHH Sauer --- , South AfricaTemporal trends in the size composition (length frequency) and length–weight (L–W) relationship of chokka squid Loligo reynaudii on the south coast of South Africa were assessed over periods spanning 22 years: length frequencies from 1996 to 2017 (with 15 years... -
A baseline assessment of coastal pH variability in a temperate South African embayment: implications for biological ocean acidification research
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: C Edworthy --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa WM Potts --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa S Dupont --- University of Gothenburg, Sweden MI Duncan --- Rhodes University, South Africa TG Bornman --- Institute for Coastal and Marine Research, Nelson Mandela University, South Africa NC James --- South African Institute for Aquatic Biodiversity (SAIAB), South AfricaCompared with the open ocean, knowledge of pH variability in coastal waters is rudimentary, especially in Africa. This is concerning as quantifying local pH conditions is critical when assessing the response of coastal species to future ocean acidification scenarios. The... -
Marine macroalgae of the Agulhas Marine Province of South Africa: biodiversity, exploitation and potential for aquaculture
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: JJ Bolton --- University of Cape Town, South Africa CD McQuaid --- Rhodes University, South AfricaThe Agulhas Marine Province (AMP) extends along most of the south coast of South Africa, from Cape Agulhas to the vicinity of the Mbashe River mouth in the Eastern Cape Province, and has its own distinctive warm-temperate seaweed flora, with... -
Contrast in larval sensitivity to low pH in sea urchins from neighbouring seagrass meadows at Inhaca Island, Mozambique
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: JA Duvane --- Eduardo Mondlane University, Mozambique D Cossa --- Eduardo Mondlane University, Mozambique DC de Abreu --- Eduardo Mondlane University, Mozambique M Mafambissa --- Eduardo Mondlane University, Mozambique MP Scarlet --- Eduardo Mondlane University, Mozambique A Macia --- Eduardo Mondlane University, Mozambique S Dupont --- University of Gothenburg, SwedenOcean acidification presents a major threat to marine life, and a large body of evidence has documented its negative effects on various marine species and ecosystems. Recent meta-analyses highlight the key role of local adaptation and have linked species’ sensitivity...
