The biomass and productivity of a seagrass community are useful for determining the ecological status of the coast. Leaf biomass and shoot density in beds of Thalassia testudinum Banks & Sol. ex K. D. Koenig, were compared for two environments in the Mexican Caribbean coast (N = 6 quadrants/site) in November 1998. Shoot and leaf biomass values were lower in the mangrove-associated meadow than in the reef lagoon meadow. This could be related to the higher percentage of epiphytes on the leaves. In addition, T. testudinum had more biomass than Syringodium filiforme Kütz in the reef lagoon.
海草群落的生物量和生产力有助于确定海岸的生态状况。1998年11月，在墨西哥加勒比海岸的两种环境中（每个地点6个样方），对泰来草（Thalassia testudinum Banks & Sol. ex K. D. Koenig）床中的叶片生物量和茎密度进行了比较。与红树林相关的草甸中的茎和叶生物量值低于珊瑚礁泻湖草甸中的值。这可能与叶片上附生植物的比例较高有关。此外，在珊瑚礁泻湖中，泰来草的生物量比丝状二药藻（Syringodium filiforme Kütz）的生物量更大。
