Biology and population dynamics of the King Mackerel (Scombereomorous commerson, Lacepede, 1800) off the coast of Natal .
(1992)This thesis provides a study on aspects of the biology and population dynamics of Scomberomorus commerson off the south east coast of southern Africa. This is necessary for the evaluation of the current management policies ... -
Association of juveniles of four fish species with sandbanks in Durban Bay, KwaZulu Natal.
(1994)Estuaries in South Africa are important nursery areas for the juveniles of many fish species. The condition of many of these systems has, however, deteriorated as a result of degradation caused by urban, industrial and ... -
Biology and stock assessment of the coastal fish, Sarpa Salpa (Sparidae), off the KwaZulu-Natal coast, South Africa.
(1995)This study investigated aspects of the biology of Sarpa salpa, such as reproduction, age and growth, and mortality, which are necessary for an assessment of the status of this species off the KwaZulu-Natal (KZN) Coast. The ... -
Age and growth of the Queen Mackerel (Scomberomorus plurilineatus) and Seventy-four (Polysteganus undulosus) of KwaZulu Natal, South Africa.
(1996)This study provides information on the age and growth of two important Iinefish species, Scomberomorus pluriline~tus and Polysteganus undulosus. Age determination for both species was carried out using otoliths and growth ... -
Artisanal fishery in socio-economic development of rural communities in Malawi : a case study of enclave villages of Lake Malawi National Park.
(1998)Fishing, and artisanal fishing in particular, plays a key role in the provision of rural employment and more importantly, household food security in the developing nations. The importance of artisanal fishery is shown in ... -
Coral propagation for aquarium specimens.
(2001)Coral reefs are being destroyed and degraded by natural and anthropogenic processes. Live corals are becoming increasingly popular as marine aquarium specimens, in both the commercial and private sectors, leading to the ... -
Modelling streamflow and sediment yield on the lower Mgeni catchment.
(2001)This study involves the application of the ACRU Agrohydrological Model to a selected study catchment in the Lower Mgeni Catchment, and its discretized subcatchments, immediately downstream of the Inanda Dam. This study was ... -
Management of the linefish resource in Southern Mozambique : a case study for Marreco (Chrysoblephus puniceus).
(2001)This study provides information on the biology, stock status and the management of C. puniceus, a key linefish resource in southern Mozambique. This is regionally endemic to Mozambique and KwaZulu-Natal. Fairly resident ... -
The status of the riverbream Acanthopagrus berda (Sparidae) in estuarine systems of northern KwaZulu-Natal, South Africa.
(2001)Acanthopagrus berda is an estuarine-dependent fish species which is widespread in the tropical Indo-Pacific. In South Africa, it is particularly abundant in the three large northern KwaZulu-Natal estuarine systems, namely ... -
The vegetation ecology of the lower Mkuze river floodplain, Northern KwaZulu-Natal : a landscape ecology perspective.
(2001)The overall aim of this study was to develop an understanding of the vegetation ecology of the lower Mkuze River floodplain from a landscape ecology perspective. The lower Mkuze River floodplain and its associated wetlands ... -
Transboundary water resource management of the Pongolo River/Rio Maputo.
(2002)In the Twenty-first Century, sustainable water management is likely to be humanity's greatest challenge in a world of ever-increasing demand. Legal instruments both international and national regulate and provide a general ... -
The macrobenthos of the Little Lagoon, Durban Bay.
(2002)The Little Lagoon is a shallow sandflat habitat situated in Durban Bay, which has been earmarked for removal, as part of the port expansion. In order to prevent the possible loss of such a significant habitat, it was ... -
The dynamics of microphytobenthos in the Mdloti and Mhlanga estuaries, Kwazulu-Natal.
(2004)Microphytobenthos (MPB) generally dominates total autotrophic biomass in temporarily open/closed estuaries (TOCEs) of South Africa. A comparative study of MPB biomass was undertaken in two KwaZulu-Natal TOCEs, the Mdloti ... -
The zooplankton of temporarily open/closed estuaries : case studies of the Mdloti and the Mhlanga estuaries, KwaZulu-Natal North Coast.
(2005)The zooplankton communities of the Mdloti and Mhlanga estuaries were studied over a 13-month period (March 2002-March 2003). Monthly daytime samples were collected from both estuaries at the lower, middle and upper reaches ... -
The commercial and recreational marine skiboat linefisheries in Richards Bay, KwaZulu-Natal.
(2005)In order to assess and improve their management, a survey of the commercial and recreational marine linefisheries in Richards Bay was conducted from June 2002 to July 2004. The ultimate aim of this survey was to develop a ... -
An assessment of changes in the Ichthyofaunal bycatch of the Tugela Bank prawn trawlers in KwaZulu-Natal.
(2006)Bycatch refers to the portion of the catch that is captured incidentally to the target species and is one of many growing problems facing the world's marine fisheries in recent years. Prawn trawling is one of the world's ... -
Genetic diversity of symbiodinium in selected corals in the Western Indian Ocean.
(2007)Coastal communities along the east African coastline rely on coral reefs and their associated resources for food security and income. However, increases in the frequency and severity of episodes of coral bleaching have ... -
Responses of Avicennia marina (Forssk.) Vierh. to contamination by selected heavy metals.
(2008)Heavy metal contamination of mangroves is of critical concern due to its accumulative and adverse effects in aquatic ecosystems. This study was undertaken to investigate the effects of mercury (Hg ), lead (Pb ), copper (Cu ... -
Influence of heterotrophic feeding on the sexual reproduction of Pocillopora verrucosa (Scleractinia, Pocilloporidae) in aquaria.
(2009)Corals are able to source autotrophically-produced carbon since they have symbiotic unicellular dinoflagellates embedded in their tissue. However, they are also known to be heterotrophic feeders and able to ingest a variety ... -
Relationship between sediment structure and infaunal amphipod communities along the Durban outfalls region on the east coast of South Africa.
