Sharks and rays commonly wash out on our beaches. There are a number of potential reasons for such strandings, but in most cases it is difficult to pinpoint the cause. The most common stranding factors are: Upwelling events, rough sea conditions, predators/infections or discarded catches

Endemic catsharks, Smoothhound sharks and guitarfish prevail amongst the species that we have recorded so far, which is alarming as many of them are classified as threatened: Despite their local abundance their geographical range is limited, which makes them particularly vulnerable to over-exploitation. These species are often considered as a nuisance or pest and current legislation in South Africa only offers very limited protection.

Consequently it is important to monitor the causes of strandings over long periods in order to make informed decisions about the management and protection of species.
