Marine Bi­ol­o­gists Mass-Pro­duce Co­ral Lar­vae

Science Illustrated - - SCIENCE UPDATE -

By col­lect­ing eggs and sperm cells from spawn­ing corals in a lab, sci­en­tists can pro­duce large quan­ti­ties of lar­vae. When the lar­vae are placed on a dy­ing reef, new corals de­velop.

SCI­EN­TISTS 1 COL­LECT

30 colonies of 15-20- cm- large corals which are ready to spawn (or­ange and pink), plac­ing them in sep­a­rate basins.

THE CORALS SPAWN 2

at night, when sci­en­tists har­vest large por­tions of egg and sperm cells. The co­ral lar­vae hatch in another basin.

LAR­VAE ARE PLACED 3

on the dam­aged reef. Nets pro­tect the lar­vae for five days, un­til they have gained a proper foothold.

EIGHT MONTHS LATER, 4

the corals have re­pro­duced. New mi­cro­scopic corals have started to grow on the dam­aged reef.
