BIODIVERSITY OF
SEAWEEDS (Eucheuma)
Distribution
The Coral Triangle – World’s richest biodiversity
– Source of Eucheuma sp.
Natural distribution of Eucheuma
Natural stocks of Eucheuma – Indo-pacific.

Eucheuma are robust and are easily
transported if they are kept moist with
seawater and are held within a temperature
range that does not harm them.

Eucheuma strains occurred naturally or have
been dispersed by human activity to the point
where marine out plantings have occurred in
at least 29 countries.
