Sairee’s new artificial reef.

The idea of an artificial reef goes back thousands of years, when the Persians created a reef in aims to block a nearby river to thwart the efforts of some Indian pirates. Since then a lot of research goes into the development of artificial reefs, the best locations, and methods, ensuring successful transplanting and further growth of the corals.
Artificial reef can be anything from a sunken shipwreck to an old shopping cart, regardless of their construction, the purpose is to provide hard surfaces where algae, and invertebrates, such as corals can attach and then grow. The eventual accumulation of the corals and algae in turn provides an intricate structure with food and shelter for different fish species.
However through research we have found corals and marine life seem to prefer particular materials when attaching to and fish to hide in. It seems that the majority of corals would prefer to start their growth, being suspended off from the sea bed, enabling the symbiotic algae to extract more sunlight, and allowing the nematocysts a better chances at feeding. When suspended the area below also creates a sheltered area for marine life.
So from knowing this we can see how successful our new artificial reef off North Sairee has become, Approximately only 5 months old, sitting at between 10-12 metres in depth and containing just 8 structures, it has started to gather the attention of different marine life from Parrot fish, to nudibranch species, which obviously see the area that offers not only shelter but a sufficient food source.
