The term ‘sardine run’ is part of the cultural heritage of the South African nation and refers to a natural phenomenon that is well known to the general public but still poorly understood from an ecological perspective. This lack of understanding has stimulated numerous hypotheses, often contradictory, that try to explain why (ultimate factors) and how (proximate factors) the run occurs. Here, we provide a new definition of the term sardine run, review the various hypotheses about the run, and… Expand
Overview of the KwaZulu-Natal sardine run
This paper provides an introduction to, and overview of, the natural phenomenon known as the KwaZulu-Natal sardine run. Previous literature on this topic and hypotheses about the reasons why, and theExpand
The 2005 KwaZulu-Natal sardine run survey sheds new light on the ecology of small pelagic fish off the east coast of South Africa
Despite much public awareness surrounding the annual migration of sardine Sardinops sagax northward along the east coast of South Africa in winter each year, relatively little research effort hasExpand
Progressive delays in the timing of sardine migration in the southwest Indian Ocean
FUNDING: None Phenological shifts represent one of the most robust bioindicators of climate change. While considerable multidecadal records of plant and animal phenology exist for the northernExpand
Otolith δ18O and microstructure analyses provide further evidence of population structure in sardine Sardinops sagax around South Africa
Sardine Sardinops sagax is an ecologically and economically important Clupeid found off the entire South African coast that includes both coastal upwelling and western boundary current systems.Expand
Incorporating parasite data in population structure studies of South African sardine Sardinops sagax
TLDR
Strong spatial gradients around South Africa in the prevalence, mean infection intensity and mean abundance of a digenean ‘tetracotyle’ type metacercarial endoparasite considered to be of the genus Cardiocephaloides and found in the humours of fish eyes support and have proved particularly convincing evidence for the sardine multiple stock hypothesis.

The quantitative use of parasite data in multistock modelling of South African sardine (Sardinops sagax)1
TLDR
This work demonstrates extension of bio-tagging to inform on the plausibility of population structure hypotheses by including parasite prevalence-by-length data in the model’s likelihood by enabling the estimation of the magnitude of mixing between semidiscrete stocks. Expand

Nine decades of fish movement research in southern Africa: a synthesis of research and findings from 1928 to 2014
TLDR
The most prominent phenomenon, emerging from this research, is that of partial migration, which describes the occurrence of resident and migratory behaviour within a coexisting animal population in southern Africa. Expand

Has the fishery contributed to a major shift in the distribution of South African sardine
TLDR
Three hypotheses explaining the change in the distribution of sardine have been proposed: intensely localized, environmentally induced, and successful spawning and recruit survival on South Africa’s south coast contributed disproportionately more towards the bulk of recruitment, and progeny spawned there now dominate the population and exhibit natal homing.

Influence of the sardine run on selected nearshore predatory teleosts in KwaZulu-Natal
TLDR
The relationships between shore-angling catch rates of nearshore predatory teleosts in KwaZulu-Natal, South Africa, and the timing of the sardine run were examined using a multiple regression model and it is not clear whether these relationships can be ascribed to a feeding migration by the predators, a reproductive migration byThe predators or an extension of suitable habitat for both prey and predators during these months.
