ABSTRACT
Larval stage is the early phase of the life cycle for the fish. The larvae are aquatic biota that are planktonic and included into the type meroplankton. Seagrass ecosystems in Pramuka Island, has important ecological functions in coastal areas, where the ecosystem is one of the nursery ground and feeding ground for fish larvae. The big difference the density of seagrass and the presence of food can influence abundance of fish larvae. Thus, it will be the base for doing this research on The relations between Seagrass Density and Fish Larvae Abundance in Pramuka, Seribu Island Jakarta. This research aims to determine the abundance of fish larvae in different seagrass densities and determine the influence of the seagrass density on the abundance of fish larvae. The method used is survey method in determining the point of sampling using purposive sampling method. The results obtained are at station I the densities in dense seagrass (34156 individuals/100m2) abundance of fish larvae value at 756 individuals/200m2 consisting of eight families. Station II medium density (26410 individuals/100m2) the value of the abundance of fish larvae is 579 individuals/200m2 consisting of 6 families, and station III precision rarely (6321 individuals/100m2) the value of fish larvae abundance at 426 individuals/200m2 consisting of 4 families. The correlation values between the abundance of fish larvae with the density of seagrass in the amount of r = 0,772. Based on the above, we can conclude that there is a close relationship between the abundance and composition of fish larvae families with seagrass density. The higher the density of seagrass, the higher the families abundance and composition of fish larvae. Similarly, the lower the density value then the value of seagrass abundance and composition of fish larvae are also lower.
