The Philippines has a rich and prolific population of sea urchins. Sea urchins are echinoderms that play an important part in marine ecology by aiding in the regulation of algae development and the overgrowth of coral reefs. One notable aspect of existence is the reproductive structure of female sea urchins, specifically their gonad, ovary, which have been subject to numerous quantitative analyses, like morphometric. Morphometric Analysis is a method of obtaining comprehensive and direct measurements when comparing variables. The present study aims to compare the morphometric analysis of the reproductive structure of female sea urchins in Barangay Daan Lungsod and Punong, Gingoog City. The study utilized a nonexperimental design by collecting 15 samples per location. The data were then administered to an online software program, SPSS, and employed T-test Independent. Results revealed that sea urchins from Punong varied significantly in length, width, and mass. However, sea urchins from Daan Lungsod showed a significant difference in the gross maturity index of color. While the gross maturity of index for gross surface texture showed no significant difference between the two sampling locations. The present study found that sea urchins from Punong are likely to be older and can possibly store more nutrients than Daan Lungsod’s. However, sea urchins from Daan Lungsod are more mature. It is recommended to do sampling in both dry and wet seasons for more reliability. The present study can be used to inform the fishermen on harvesting and help manage sea urchin populations sustainably for ecological and economic reasons.
