Abundance, biomass and species composition of nearshore fish assemblages in Ghana, West Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: FKE Nunoo DB Eggleston CJ VanderpuyeMany of the world's fish populations are overexploited, including Ghana's fish resources. This study examines spatio-temporal trends in fish species composition in relation to biotic, abiotic and anthropogenic factors, towards achieving better-informed management of the beach-seine fisheries. Fishery-dependent data were... -
Coastal currents and temperatures along the eastern region of Algoa Bay, South Africa, with implications for transport and shelf–bay water exchange
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MJ Roberts --- Department of Environmental Affairs, South AfricaBoat ADCP surveys and an eight-month deployment of a 1 200 kHz ADCP were used to study the nearshore (5–25 m depth) current and temperature patterns along the eastern coastal region of Algoa Bay, on the south-east coast of South... -
Shallow-water, nearshore current dynamics in Algoa Bay, South Africa, with notes on the implications for larval fish dispersal
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: P Pattrick --- Department of Ichthyology and Fisheries Science, South Africa NA Strydom --- , South Africa WS Goschen --- , South AfricaNearshore currents play a vital role in the transport of eggs and larval stages of fish. However, little is known about their complexity and the implications for dispersal of fish larvae. The study describes the complexity of the shallow nearshore... -
Short-term variability in alongshore winds and temperature off Swakopmund, Namibia, during a non-upwelling event in 1998–1999
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: CH Bartholomae E HagenSwakopmund is a popular coastal resort in Namibia, especially during the summer holiday season when daily sea temperatures can fluctuate several degrees in a short period. Hourly measurements of the near-bottom water temperature were collected off the Swakopmund Jetty to... -
Photo-identification and habitat use of Atlantic humpback dolphins Sousa teuszii around the Río Nuñez Estuary in Guinea, West Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: CR Weir --- Ketos Ecology, UKEcological data for the Atlantic humpback dolphin Sousa teuszii are scant. Six on-effort Sousa teuszii sightings were recorded during 817.6 km of boat-based effort in the Río Nuñez region of Guinea during October and November 2013. Two incidental sightings were also... -
Spatial patterns and environmental drivers of demersal fish assemblages in the Swartkops and Sundays estuarine to marine seascapes, South Africa
Item type: Journal Article • Journal: Anthropology Southern Africa • Authors: P Nodo --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa AR Childs --- Rhodes University, South Africa P Pattrick --- Nelson Mandela University, South Africa NC James --- South African Institute for Aquatic Biodiversity (SAIAB), South AfricaEstuaries are often observed as the boundary between the ocean and the river, separating coastal environments, rather than being seen as a continuum. Owing to insufficient research on demersal fish communities across nearshore marine to estuarine habitats, particularly in South...
