Abstract

Gastropods are one of the classes of mollusks that associate well with seagrass ecosystems. The waters of Pasir Putih are included in a coastal area where many types of gastropods are found in seagrass ecosystems. However, not all types of gastropods in seagrass beds in this region are well known. For this reason, this study aims to determine the types of gastropods associated with seagrass ecosystems in the waters of Pasir Putih, Manokwari. But specifically the objectives of this study are divided into 3, knowing the types of gastropods, seagrass species and the association of gastropods with seagrass in Pasir Putih Waters, Manokwari. In sampling, the quadratic transect method was used, drawn perpendicularly from the shore towards the shore. Physical parameters of water chemistry were observed in situ, this data collection method used was descriptive method. Based on the results of the identification that has been done, that there are 115 individuals, 42 species and 15 families that exist in the White Sand Waters, Manokwari. Four seagrass species were found, namely Cymodocea rotundata, Halodule pinifolia, Halophila ovalis, and Syringodium isoetifolium.

Abstract

Seagrass is a plant that lives in shallow seas with various different types of substrate and seagrass is a type of plant that has flowers, leaves and fruit. Manokwari City is one of the capital cities of West Papua Province which has waters, one of which is Pasir Putih waters. The diversity of seagrass species in this location is not yet well known, for this reason it is necessary to conduct research regarding the diversity of seagrass in the waters of Pasir Putih, Manokwari, West Papua. This research was conducted in July using the quadrant transect method. Based on research results, the types of seagrass found around the waters of white sand beaches consist of 4 types, namely Cymodocea rotundata, Halophila ovalis, Halodule pinifolia and Syringodium isoetofolium. The highest density of seagrass species is the Syringodium isoetifolium type with a value of 958 stands/m2, the highest relative density is the Syringodium isoetifolium seagrass type with a density percentage of 54%. The highest relative frequency is the seagrass species Halophila ovalis with a percentage of 34%. The level of diversity of seagrass species in transect I is in the medium group and in transects II and III is in the low group. The highest uniformity index value in transect I was 0.82 and the dominance index can be concluded that there is no type of seagrass that dominates the community.
