Scientists found 90% of young coral surveyed remained healthy compared with 25% of older corals, after mass bleaching event in the Caribbean
Young corals bred using in vitro fertilisation (IVF) and planted in reefs around the US, Mexico and the Caribbean have surprised scientists, after most survived last year’s record marine heatwave, while older corals struggled.
A study has found that 90% of the young IVF-created corals surveyed remained healthy and colourful, holding on to the algae that live within them and supply them with nutrition. In contrast, only about a quarter of older non-IVF corals remained healthy.
