IF you saw the BBC’s amazing Blue Planet II, you’ll know how much danger the world’s coral is in.
However, there was potential good news for coral reefs this week, as scientists revealed a clever technique that can boost coral production.
A study in Scientific Reports showed how a cheap cement tetrapod (the four-pronged thingy in the picture above) can be coated with coral larvae in a lab. The tetrapods are then jammed into reefs by scuba divers (below). The four prongs help to keep the tetrapods in place, allowing coral to grow more quickly than normal.
Researchers are now working on ways of increasing the success rate of the technique, as well as trying different materials for the tetrapods.
