ABSTRACT
This study aimed at determining the population profile of echinoderms at Bolabog, Boracay Island in terms of population abundance, population density, and species diversity. The study hypothesized that there exists no significant variation in the distribution of echinoderms in each site per class. The researchers chose to conduct their study in the waters or Bolabog, Balabag, Malay, Aklan since there had been no study conducted there. The test organisms were echinoderms found in the five selected study sites in the area namely: Class Asteroidea, Class Echinoidea, and Class Holothuroidea. In this study, mean was used as descriptive statistical tool and chi-square as inferential set at a0.05 level of significance.
Based on the data gathered, Echinoidea is the most abundant and diverse, has the highest population density, and shows a significant variation of their distribution in the five study sites.
