Abstract

Observations camed out at Mandapam from 1983 to 1986 on the colonisation and growth of Halodllie 11llinervis and Halophila ovalis are presented. Dislodged bits of the sea grasses were brought into three ponds of 6Ox30xlm from Palk Bay due to cyclonic and tidal conditions of the sea at the end of 1983. In pond I. H. uninervis alone had established and grown from about 90 plantslm2 in January 1984 to 800/m2 in October, reaching the peak abundance of 8.100/m2 during February, 1986. In the other two ponds, both the species got established. H. ovalis was the princ~pal species in the order of about 6:1 in pond II. while H. uninervis was dominant in pond III, in the order of about 3.4:1. The peak: levels of abundance for H. ovalis and H. uninervis in the former pond were about 7,700/m2 and 1,200/m2 in March and January 1986 respectively.
