Observations on the biology and seasonal variation in feeding of the East Coast redeye round herring (Etrumeus wongratanai) (Clupeiformes), off Scottburgh, KwaZulu-Natal, South Africa
(University of the Western Cape, 2016)
The basic biology and ecology of Etrumeus wongratanai was investigated from samples of fish collected by jigging off Scottburgh, Kwazulu-Natal throughout 2014 and 2015. A total of 516 otoliths, 401 gonads, 140 stomachs and ...
Investigating phytoplankton fluctuations and drum filter effectiveness on an abalone farm in Hermanus, South Africa.
(University of the Western Cape, 2021)
Aquaculture is a growing industry in South Africa, with the production of abalone, Haliotis midae, at
the forefront. The Western Cape Province hosts 12 of the 18 abalone farms in South Africa, with a
concentration of ...
A systematic conservation plan for threatened freshwater wetlanddependent waterbirds across South Africa
(University of Western Cape, 2020)
Freshwater ecosystems are valuable to all components of biodiversity communities. Globally, these
ecosystems are threatened by human activity and as a consequence, many vertebrates, including
waterbirds, have become ...
Distributional and dietary overlap between two common squaloid sharks, squalus acutipinnis and squalus bassi, caught as bycatch off the coast of South Africa
(University of Western Cape, 2021)
Squalus acutipinnis and S. bassi may be the most common dogfish species around South Africa, and show overlap in their latitudinal and bathymetric distributions. Even though these sharks are likely endemics, they are also ...
Abalone nutrition – growth performance of Haliotis midae in relation to variable artificial feeds
(University of Western Cape, 2020)
Abalone are among the most expensive and sought-after seafood subjects. In South Africa, Haliotis midae is the only commercially significant abalone species and it has become increasingly sold on the global market. The ...
Chytridiomycosis in amphibian populations in the Western Cape, South Africa
(University of the Western Cape, 2002)
There have been many cases reported of amphibian populations declining. These are often due to anthropogenic factors such as habitat destruction and pollution. However, some declines have not had an obvious cause and many ...
The effects of real exchange rate misalignment on exports in South Africa.
(University of Western Cape, 2020)
The purpose of this study was to evaluate econometrically the effects of real exchange rate misalignment on South African exports between the period 1994 and 2015 using quarterly time-series data. Cointegration tests were ...
Specias delimitation and assessment of genetic variability in Carpobrotus (Alzoaceae): evidence from amplified fragment length polymorphisms
(University of the Western Cape, 2004)
Species of Carpobrotus (Aizoaceae: Ruschioideae) are widely spread throughout South Africa and are commonly used for their medicinal properties. The genus consists of 13 species of which seven occur in South Africa, five ...
Species delimitation and assessment of genetic variability in Carpobrotus (Aizoaceae): evidence from amplified fragment length polymorphisms
(University of the Western Cape, 2004)
During the course of this thesis, AFLP technique was successfully applied to the Aizoaceae taxa. This study involved a substantial component of laboratory work including generating and analysing AFLP data, the operation ...
Applying a lagrangian trajectory model to investigate and describe the distribution of drifting ecklonia maxima within the benguela upwelling system
(University of the Western Cape, 2023)
Macroalgal morphological variation is determined to a large extent by a combination of environmental factors, with wave exposure and temperature perhaps the main influences, as they are key environmental properties to which ...
