Accretion versus bioerosion on the Maputaland reefs in South Africa - The major processes.
(2011)The development of coral reefs is largely restricted to areas within the tropics where favourable conditions for both coral and reef growth prevail. There is, however, a continuum from these typical, accretive reefs in ... -
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 ... -
An assessment of abundance trends and biology of langoustines (Metanephrops mozambicus) and pink prawns (Haliporoides triarthrus) from the deep-water trawl fishery off eastern South Africa.
(2013)Deep-water trawling (>200 m deep) for crustaceans in the South West Indian Ocean (SWIO) yields catches of several species, including prawns (Haliporoides triarthrus, Aristaeomorpha foliacea, Aristeus antennatus and Aristeus ... -
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 ... -
An assessment of the shore-based and offshore boat-based linefisheries of KwaZulu-Natal, South Africa.
(2011)The purpose of this study was to evaluate the current management effectiveness of the KwaZulu-Natal linefishery (i.e. the shore linefishery and the offshore boat-based linefishery). Methods used included a stratified-random ... -
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 ... -
Biodiversity of soft sediment macrobenthic fauna of the KwaZulu-Natal Bight midshelf.
(2013)The KwaZulu-Natal Bight is influenced by various nutrient inputs from the Thukela River and particular oceanographic features of the shelf such as the St Lucia upwelling cell and the Durban lee eddy that are in turn ... -
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 ... -
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 ... -
Chemical cue interactions between alien invasive and native aquatic gastropods in the iSimangaliso Wetland Park, South Africa.
(2013)The importance of chemical cues in mediating interactions among individuals and structuring communities is being increasingly recognized in aquatic environments. Chemical cues have been shown to drive predator-prey ... -
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 ... -
Community dynamics of meiofauna during a wet phase in the St Lucia estuarine system, South Africa.
(2015)Meiofauna are an important component within the benthic environment of any aquatic habitat. Despite their significance and ubiquitous nature, these organisms are relatively poorly studied in Africa. Following a decade long ... -
Community structure and function of macrobenthos in three feature areas of the Natal Bight, South Africa.
(2013)The Natal Bight off the east coast of South Africa is a unique shelf habitat, exhibiting high secondary productivity and supporting high diversity. Ecosystem attributes are influenced by local oceanographic features and ... -
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 ... -
Coral recruitment on a high-latitude reef at Sodwana Bay, South Africa : research methods and dynamics.
(2011)Coral recruitment is a key process that contributes to the community structure and resilience of coral reefs. As such, quantification of this process is important to assist with the management of these threatened ecosystems. ... -
Dietary dynamics of two key fish species in the St Lucia estuarine system, South Africa.
(2014)Among the 155 species of fish recorded so far in the St Lucia estuarine lake, Oreochromis mossambicus and Ambassis ambassis are the two most prominent. Although originally endemic to southern Africa, O. mossambicus is ... -
Diversity and distribution of subtidal soft-bottom macrofauna of the Isimangaliso Wetland Park, South Africa.
(2014)There have been no previous studies describing the subtidal soft-bottom macrofaunal assemblages of the iSimangaliso Wetland Park or how they are influenced by the ecological and environmental processes associated with coral ... -
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 dynamics of nano- and microplankton in the St. Lucia estuarine lake system, KwaZulu-Natal.
(2013)St. Lucia estuarine lake system has a history of episodic droughts and floods leading to a high variability in physico-chemical characteristics which may influence the community structure of nano- and microplankton ...
