Abstract de Bruyn, P. A., Moloney, C. L., and Schleyer, M. H. 2009. Application of age-structured production models to assess oyster Striostrea margaritacea populations managed by rotational harvesting in KwaZulu-Natal, South Africa. – ICES Journal of Masrine Science, 66: 408–419. Oysters have been harvested in KwaZulu-Natal for more than a century, by both commercial and recreational users. However, management of the resource has been based on ad hoc measures rather than quantitative, defensible management plans. Early in the history of the fishery, a rotational harvesting strategy was employed, but it has changed over time. At present, there are 10 management zones, each fished 2 years out of five, and recreational harvesting is allowed in the year preceding commercial harvesting. To assess the status of the oyster resource as well as the historical levels of exploitation, age-structured production models were applied to the oyster populations in the five North Coast management zones. The model fits to the observed data were good. Oyster abundance differed among zones, with the lowest abundance in the two most northern zones. As these zones had only recently been established, however, the paucity of data renders their assessments uncertain. The southernmost zone had the greatest oyster abundance. The benefits of rotational harvesting were demonstrated by the model outputs, which showed rapid population recovery during fallow years, suggesting sustainability of the resource. It is recommended that rotational harvesting continues to be used to manage oysters in KwaZulu-Natal.

Background: Pregnancy among adolescents in South Africa is a growing concern as it may be associated with adverse socioeconomic and health impacts. Timeous initiation and optimal utilisation of antenatal care (ANC) services is imperative to ensure positive pregnancy outcomes. However, this is not always possible owing to various challenges. Methods: A multi-method study design using both retrospective record review and qualitative interviews was undertaken at a district hospital on the North Coast of KwaZulu-Natal, South Africa. Data on ANC attendance trends and obstetric/perinatal outcomes for all recorded adolescent pregnancies (13–16 years) at the district hospital under study was collected over 3 years (2011–2013) (n = 314). Qualitative interviews with randomly selected pregnant adolescents were conducted to assess experiences of ANC access and utilisation. Results: Late ANC booking and reduced ANC visits were common for adolescent pregnancies. Under-utilisation of ANC (i.e. less than 4 visits) was significantly associated with lower gestational age (< 37 weeks) (OR = 2.64; 95% CI = 1.04; 6.74; p < 0.05). Low birthweight, low Apgar scores as well as the incidence of maternal anaemia and pregnancy-induced hypertension (PIH) were found to be related to late ANC booking. In-depth interviews suggested that teenagers suffered emotional vulnerability linked to family, partner and financial support. They discussed various barriers linked with accessing ANC while acknowledging perceived benefits. Conclusion: Adolescent pregnancy was associated with late booking and reduced ANC visits, which was a risk for adverse maternal health outcomes. In-depth interviews suggested numerous challenges associated with ANC access including; financial barriers, attitude of healthcare workers (HCWs), long queues, distance travelled to access ANC services, human immunodeficiency virus (HIV) status and a lack of knowledge.

The Stability

Alien invasive vegetation threatens the functioning and existence of natural ecosystems in South Africa because many of these plants have no predators or competitors, allowing them to dominate the ecosystem which they inhabit. The rapid proliferation of this alien vegetation, ascribed to the increase in afforestation and changes in land use, has had significant adverse impacts on water resources, biodiversity and the stability as well as integrity of these ecosystems. Although eradicating alien invasive vegetation gives rise to a number of different benefits, this process entails enormous costs. Consequently, in order to establish the economic viability of alien plant eradication it is essential to analyse these costs as well as the benefits associated with eradication.
