For each area, the catch composition was calculated and the species assemblages were investigated using cluster analysis and multi-dimensional scaling. Finally, for each coast, the weight of fish discarded annually was estimated. On the south coast, although hake dominated, between 21% and 47% of the catch was not hake, depending on the fishing area. In comparison, hake dominated west coast catches, the proportion of hake increasing with depth. For each fishery investigated, approximately 90% of the catch was processed and landed. However, estimates of annual discards indicate that the south and west coast fisheries may annually discard 9000 or 10,000 t and 17,000 or 25,000 t, of undersized and unutilizable fish and offal, respectively, depending on the estimation method used. When developing strategies to limit or enhance utilization of bycatch, cognisance should be taken of the differences in catch composition between the south and west coasts and of the importance of bycatch revenue to south coast fishing companies.]]> Tue 14 May 2024 05:07:15 SAST ]]> The need for an inland fisheries policy in South Africa : a case study of the North West Province https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6769 Tue 14 May 2024 04:53:12 SAST ]]> Department of Ichthyology and Fisheries Science: research report series 19 https://commons.ufh.ac.za/vital/access/manager/Repository/vital:7161 Tue 14 May 2024 04:28:37 SAST ]]> Does the endangered Knysna seahorse, Hippocampus capensis, have a preference for aquatic vegetation type, cover or height? https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6775 75%) than at sites with lower cover.

In areas with 100% cover, adult size (mean and maximum lengths) was greater on exposed sites, but density showed the reverse and was negatively correlated with maximum wave strength (r = −0.84). Despite differences in adult densities and sizes, biomass, which is a product of the two, showed no significant difference between the two shore types (ANOVA P > 0.05). Thus wave exposure dramatically affects density, recruitment and mussel size, but not recruitment timing or biomass where there is 100% cover, and mediates a three-way interaction among food supply, larval supply and intraspecific competition for space. In contrast to shores with saturation recruitment, mussel biomass here appears to be limited by recruit supply and constraints of food, especially on sheltered shores, while density is regulated through intraspecific competition for space primarily on exposed shores and at small spatial scales.]]> Fri 26 Apr 2024 10:45:35 SAST ]]> The decline of water hyacinth on Lake Victoria was due to biological control by Neochetina spp https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6927 Fri 26 Apr 2024 10:36:54 SAST ]]> Impact of nutrients and herbivory by Eccritotarsus catarinensis on the biological control of water hyacinth, Eichhornia crassipes https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6945 Fri 26 Apr 2024 10:36:19 SAST ]]> Evaluating compression as an enabler for centralised monitoring in a Next Generation Network https://commons.ufh.ac.za/vital/access/manager/Repository/vital:72495 Fri 17 May 2024 19:37:09 SAST ]]> Bridging the gap for Next Generation Services: Presence Services on Legacy Devices https://commons.ufh.ac.za/vital/access/manager/Repository/vital:72491 Fri 17 May 2024 19:10:54 SAST ]]> Bridging the gap for Next Generation Services: Presence Services on Legacy Devices https://commons.ufh.ac.za/vital/access/manager/Repository/vital:72492 Fri 17 May 2024 19:07:07 SAST ]]> A geopolitical analysis of long term internet network telescope traffic https://commons.ufh.ac.za/vital/access/manager/Repository/vital:72489 Fri 17 May 2024 18:48:19 SAST ]]> The importance of dry woodlands and forests in rural livelihoods and poverty alleviation in South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6653 Fri 10 May 2024 15:40:38 SAST ]]> The effects of fire on post-fire seed germination of selected Savanna woody species https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43912 Fri 10 May 2024 15:39:44 SAST ]]> Factors influencing prices of medicinal plants traded in the Lowveld, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43713 Fri 10 May 2024 15:39:12 SAST ]]> Conceptualizing the human use of wild edible herbs for conservation in South African communal areas https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6626 Fri 10 May 2024 15:38:05 SAST ]]> Changes in fuelwood use and selection following electrification in the Bushbuckridge lowveld, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6641 Fri 10 May 2024 15:37:26 SAST ]]> Exploring the options for fuelwood policies to support poverty alleviation policies: Evolving dimensions in South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43709 Fri 10 May 2024 14:44:00 SAST ]]> Growth of Aloe ferox Mill. at selected sites in the Makana region of the Eastern Cape https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6654 Fri 10 May 2024 03:37:30 SAST ]]> Assessing the effects of invasive alien species on rural livelihoods: Case examples and a framework from South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43715 Fri 10 May 2024 03:36:29 SAST ]]>
