Currents along the Tsitsikamma coast, South Africa, and potential transport of squid paralarvae and ichthyoplankton
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MJ Roberts M van den BergIn July 1998, a bottom-mounted Acoustic Doppler Current Profiler was deployed at 36m depth in the centre of the Tsitsikamma National Park on the eastern Agulhas Bank, South Africa. The purpose was to investigate transport of chokka squid Loligo vulgaris... -
First Lagrangian ROMS–IBM simulations indicate large losses of chokka squid Loligo reynaudii paralarvae from South Africa's Agulhas Bank
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MJ Roberts --- Department of Environmental Affairs, South Africa C Mullon --- , FrancePresent knowledge of ocean currents based on in situ observation and models suggests that passive biological material such as eggs and larvae can be advected offshore away from the Agulhas Bank, South Africa, and hence removed from the ecosystem on... -
Life cycle of chokka-squid Loligo reynaudii in South African waters
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MR Lipiński --- Department of Ichthyology and Fisheries Science, South Africa JSF van der Vyver --- Department of Ichthyology and Fisheries Science, South Africa P Shaw --- Institute of Biological, Environmental and Rural Sciences, Aberystwyth University Penglais, UK WHH Sauer --- Department of Ichthyology and Fisheries Science, South AfricaThis short note summarises past and current knowledge of the life cycle of chokka-squid Loligo reynaudii d’Orbigny, 1845, in South African waters. Prior to approximately 2010, the chokka-squid stock was considered simple and uniform, with one paralarval pool, the drift...
