Abstract:
The research was done in January 2012 with the aim of knowing the
species and biomass of seagrass. The field work was conducted in the coastal
water of Selat Mie Village, Moro District, Karimun Regency, Riau Archipelago.
Seagrass sample for biomass study were taken from qudrants (1x1 m2) that
were plaud in 3 stasion. This research shown that were 1 (one) spesies of seagrass
Enhalus acoroides. The total density of seagrass was in the range of 19,67-22,93
tunas/m2. The weight of fresh seagrass ranged from 47,4-71,1 gr/m2, dry weight of
seagrass ranged from 18,5-20 gr/m2, ash weight seagrass ranged from 3,2-8,6
gr/m2, and organic biomass ranged from 0,316-0,354 gr/m2. Water quality
parameter values shown that Selat Mie water is suitable for supporting the live of
seagrass.
