Biomass, Growth and Productivity of Seagrass; Enhalus acoroides (Linn. f) in Khung Kraben Bay, Chanthaburi, Thailand

Abstract

The biomass, growth and productivity of seagrass; Enhalus acoroides (Linn. f) were measured in Khung Kraben Bay, Chanthaburi, Thailand during the period of 1995-1996. The average standing crop biomass of leaves was 146.37 g dry wt. m^-2, while average relative growth rate ranged from 0.0224 to 0.0359 g g^-1 day^-1. The specific growth rate ranged from 2.5 to 4.7% with turnover time of 21-40 days. Productivity was estimated by leaf marking method. The average leaf productivity was 4.24 g dry wt. m^-2 day^-1. Data on leaf length and leaf growth indicated that new leaf production continued throughout the year with the average leaf growth rate of 1.52 cm day^-1.
