Abstract:
Starfish as one of the macrozoobenthos in coastal and marine waters has various important roles.
However, with the effects of global warming that alters the habitat function and exploitation of
starfish cause its existence in the threatened one of them in the area of MenjanganBesar Island.
Until now, no studies have reported what kind of starfish is found in the waters of
MenjanganBesar Island and what are the environmental factors that influence the starfish color.
This study aims to determine the types of sea stars that are found around the waters of
MenjanganBesar Island and what factors influence it. The research was conducted in May 2017
in MenjanganBesar Island. The samples were obtained from 3 research stations. Based on
research that has been done in the waters of MenjanganBesar Island found 4 types of sea stars
that is Linckialaevigata, Culcita sp., Protoreasternodosus, and Achantasterplancii.
Protoreasternodosus is the largest number of sea stars found in the study sites. Environmental
factors that affect the body color of Culcita sp. Is the salinity of water, organic matter, and
dissolved oxygen with positive correlation, whereas the water temperature is negatively
correlated. Environmental factors that affect the color of Linckialaevigata and Achantasterplancii
are water pH with positive correlation, while the color of Protoreasternodosus is negatively
correlated with water pH. |
