Nature offers resources that provide life and livelihoods.

But if these resources aren’t used sustainably, then it threatens the health of our ecosystems – and in turn impacts on our wellbeing, and on our livelihoods.

It’s therefore essential to prevent over-exploitation and over-use. In the Kogelberg Biosphere Reserve, nature offers us an abundance of resources: water for life, fynbos for flower markets, food from the ocean, thatch for roofing, and so much more.

But it’s not always used sustainably. One of our biggest challenges is the illegal over-exploitation of a strange-looking sea snail that lives just off our coastline: abalone (or perlemoen).

In the past, great pockets of abalone could be seen lying 2-3m deep in the waters off our coast. However, the Asian market now demands abalone en masse, which has led to illegal poaching operations running along our shores.

These poaching operations rob South Africa and its people of this resource and the income that could have been derived from its sustainable harvesting. Today it’s illegal to remove abalone at all from the wild.

Abalone (Haliotis midae

Abalone (Haliotis midae) take 6 to 7 years to reach sexual maturity in the wild and at this age the shell diameter is a minimum of 80-90mm but more commonly 130-140mm. When they reach a stage where they are ready to settle on the near-shore seabed, they must be in the right environment, otherwise they die. Ideally, they find a sea-urchin to settle under. Not only do sea urchins protect the tiny abalone from predation by fish, urchins also feed on kelp so there’s a supply of detritus for the developing abalone. Once the young abalone achieve a shell diameter of about 30-50mm, they find a rocky surface on which to settle. By then they have developed a rasping tongue or radula that allow them to rasp away at kelp fronds to feed.

Abalone must be gregarious and live close together otherwise the female eggs will go unfertilised if there are no males nearby to release sperm. This is where over-exploitation (including poaching) have brought wild abalone stocks to the point of extinction. This is made worse when undersized and therefore sexually-immature abalone are taken, which places more strain on stocks already under stress.

All of this shows how important it is that there should be strategically placed marine reserves where wild stocks of marine organisms can live and reproduce unhindered by man.

THREAT

The Kogelberg Biosphere Reserve takes this threat very seriously. We are a member of the local community police forum, working to address ongoing abalone poaching and find alternative solutions and job creation opportunities.
