Biomass Of Sea grass At Selat Mie Village Coastal Water, Moro District, Karimun Regency, Riau Archipelago

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.
