https://commons.ru.ac.za/vital/access/manager/Repository/vital:5354 70%) throughout the estuary, with two distinct groups being identified on the basis of substratum type. The sampling stations near the mouth with a sandy substratum were distinguished from all other sampling sites in the estuary. The dominant estuarine-spawning species were represented by all life-history stages, suggesting that they bred successfully in the estuary. This group was numerically and gravimetrically dominated by the two zooplanktivorous shoaling species Gilchristella aestuaria and Atherina breviceps with density extrapolated population size estimates of 420 973 and 198 275 individuals, and biomass estimates of 1.6 and 0.6 g m⁻² respectively. The total population size of all estuarine-spawning species with a mean biomass 00.4 g m⁻² was estimated at 754 217 individuals. Population size estimates of the marine-spawning species were calculated using data obtained from three independent mark-recapture experiments. The assumptions for the mark-recapture analyses were adequately met and it was concluded that the techniques provided reliable estimates of population size. However, estimates obtained from density extrapolation revealed enormous variability and were considered to be unreliable. The total population size was estimated at 63 342, 18 592 and 13 5 192 during the three mark-recapture experiments respectively. The numerically dominant species during all three experiments was Rhabdosargus holubi. Biomass production of the marine-spawning species was evaluated over a 123 day census period when population sizes and estimates of growth rates were known. Productivity for all fishes with a standing stock of 26.2 g m⁻² was calculated at 4.5 g m⁻² month01 Rhabdosargus holubi accounted for more than 75% of the total marine fish productivity. This study draws attention to the success of Rhabdosargus holubi in the East Kleinemonde estuary, which is ascribed to aspects of its biology. These include an extended breeding season, the ability to recruit into the estuary under adverse open mouth conditions and its omnivorous food habits. The dominance of this migratory species suggests that it plays an important role in the transfer of energy to the coastal marine environment when the mouth of the East Kleinemonde estuary opens. Predation by birds and a dominant piscivorous fish (Lichia amia) was quantitatively assessed over a period of two years. Monthly food consumption by all piscivorous birds revealed large temporal variability, ranging from 32 to 466 kg month-I An unusual invasion of Cape cormorants during the winter of 1994 accounted for large scale mortality (2246 kg of fish) over a relatively short period. The predatory impact of this episodic event was reflected in the findings of the fish mark-recapture experiments, which revealed a 70% reduction in the total population of marine-spawning fishes (above a certain minimum size) in the estuary subsequent to this invasion. Monthly food consumption by the Lichia amia population in the estuary was calculated at 68 and 58 kg month-I for two distinct time periods when the population size was known. These findings suggest that this species is the top piscivorous predator in the East Kleinemonde estuary. Finally, the findings of this study highlight the temporal variability of fish populations within a single estuary. It is suggested that predation and estuary mouth conditions are the main factors influencing the abundance (and its variability) of individual species in the East Kleinemonde estuary.]]> Thu 13 May 2021 06:28:19 SAST ]]> Catalytic reactions of platinum group metal phthalocyanines https://commons.ru.ac.za/vital/access/manager/Repository/vital:4396 Thu 13 May 2021 06:27:12 SAST ]]> An experimental study of the effect of Acacia mearnsii (black wattle trees) on streamflow in the Sand River, Eastern Cape https://commons.ru.ac.za/vital/access/manager/Repository/vital:4832 Thu 13 May 2021 06:26:21 SAST ]]> Aspects of the ecology of fishes associated with salt marshes and adjacent habitats in a temperate South African estuary https://commons.ru.ac.za/vital/access/manager/Repository/vital:5365 Thu 13 May 2021 06:25:53 SAST ]]> Migrant labour and colonial rule in Basutoland, 1890-1930 https://commons.ru.ac.za/vital/access/manager/Repository/vital:20302 Thu 13 May 2021 06:07:55 SAST ]]> A case study of feedback strategies in The Open Learning Systems Trust (OLSET) Radio Learning Programmes https://commons.ru.ac.za/vital/access/manager/Repository/vital:2352 Thu 13 May 2021 05:48:56 SAST ]]> Investigating systemic factors affecting science learning in Curriculum 2005 : case studies of two schools https://commons.ru.ac.za/vital/access/manager/Repository/vital:1588 Thu 13 May 2021 05:28:25 SAST ]]> Evaluation of a 'defouling on demand' strategy for the ultrafiltration of brown water using activatable enzymes https://commons.ru.ac.za/vital/access/manager/Repository/vital:3904 Thu 13 May 2021 05:05:44 SAST ]]> An investigation into the effect of military influences on the theology and form of The Spiritual Exercise of Ignatius of Loyola https://commons.ru.ac.za/vital/access/manager/Repository/vital:1241 Thu 13 May 2021 04:27:40 SAST ]]> A contribution towards the taxonomy of the ichthyoplankton species community and an understanding of its dynamics along the south-east coast of South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:5342 Thu 13 May 2021 03:31:37 SAST ]]> Imbongi and griot: toward a comparative analysis of oral poetics in Southern and West Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:27576 Thu 13 May 2021 03:21:56 SAST ]]> Insubordination in the workplace https://commons.ru.ac.za/vital/access/manager/Repository/vital:3668 Thu 13 May 2021 03:04:24 SAST ]]> A comparison of the views of South African and American photojournalists to the digital manipulation of news photographs https://commons.ru.ac.za/vital/access/manager/Repository/vital:3420 Thu 13 May 2021 02:40:50 SAST ]]> An investigation into the structure and process of forgiveness following gross human rights violations https://commons.ru.ac.za/vital/access/manager/Repository/vital:2921 Thu 13 May 2021 02:25:46 SAST ]]> New bells, new founder - Hillandale, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:6163 Thu 13 May 2021 02:23:30 SAST ]]> Guy Butler (obituary) https://commons.ru.ac.za/vital/access/manager/Repository/vital:7052 Thu 13 May 2021 02:21:09 SAST ]]> Burned, banished or burnished a pilot study of a school reintegration programme https://commons.ru.ac.za/vital/access/manager/Repository/vital:2995 Thu 13 May 2021 02:10:58 SAST ]]> An examination of employee participation as provided for in the Labour Relations Act 66 of 1995 https://commons.ru.ac.za/vital/access/manager/Repository/vital:3676 Thu 13 May 2021 01:51:46 SAST ]]> An investigation into the use of IEEE 1394 for audio and control data distribution in music studio environments https://commons.ru.ac.za/vital/access/manager/Repository/vital:4619 Thu 13 May 2021 01:45:34 SAST ]]> Development of a model of performance indicators required for the effective management of South African Universities and Technikons https://commons.ru.ac.za/vital/access/manager/Repository/vital:10826 Thu 13 May 2021 01:09:44 SAST ]]> An investigation into the neuroprotective properties of melatonin https://commons.ru.ac.za/vital/access/manager/Repository/vital:3900 Thu 13 May 2021 01:07:11 SAST ]]> A pilot study of the use of groupwork in biology education at the Griffiths Mxenge College of Education : a research project ;
