Cymodocea serrulata is common and widespread. The population is thought to be stable, although there are reported declines locally due to anthropogenic threats. However this species is fast growing and can recolonize after disturbance. This species is listed as Least Concern.
|Range Description:||Cymodocea serrulata has a wide Indo-Pacific distribution. In the Pacific, it is found from southern Japan, Taiwan and Hainan, China, the Philippines, Indonesia, and Malaysia extending to the southern tip of Vietnam and the Gulf of Thailand and across insular Southeast Asia to New Caledonia, northern Australia and across Micronesia. |
In the Indian Ocean, it is found from Chabjuwardoo Bay in mid-Western Australia extending across the Timor Sea, the south coast of Indonesia, and throughout the Andaman Sea. In India, it is found from the Coromandel Coast to the Malabar Coast and in the Lakshadweep Islands. It ranges from the Red Sea south to the east coast of South Africa to Madagascar and the islands of the western Indian Ocean.

|Population:||Cymodocea serrulata is a fairly common and widespread species. The overall population is thought to be stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||Cymodocea serrulata grows on muddy sand, fine sand or sand with coral rubble substrates in the intertidal zone. It is a mid-successional species, and can colonize very quickly once established. This species can quickly recover or return after a disturbance. This is a pioneer species in Mozambique in silted channels. In eastern Australia, it occurs in deeper sediments and has been linked to increased rates of sediment accretion. This species is a food for dugongs when other resources are low. It is also grazed on by fish and urchins.|
|Use and Trade:||This species is sometimes used as fertilizer in India.|
Cymodocea serrulata is threatened by localized coastal development, pollution, dredging, siltation and destructive fishing methods. This species is believed to be sensitive to decreases in salinity (such as those caused by increasing freshwater run-off from hard surfaces). This species completely disappeared after a cyclone on Magnetic Island, but has completely recovered within 20 years (Birch and Birch 1994).
However, this species is more resilient to sedimentation compared to other coastal seagrass species and is very quick to recover from disturbance.
|Conservation Actions:||Cymodocea serrulata is protected in various marine parks and protected areas within its range. All seagrass species are protected in India since 1993.|
