| Summary, etc. |
This study aimed to determine the water quality and wharf roach (Ligia sp.)<br/>abundance in Ubihan Riverine Ecosystem, Bulacan, Philippines, during five sampling<br/>months from December 2023 to April 2024. The samples were collected in three sampling<br/>sites: Site 1 (near boat terminal), Site 2 (fishing spot near construction area), and Site 3<br/>(residential area, boat waterway). Grab and composite sampling methods were used in the<br/>collection of water samples. The wharf roach specimens were collected using a handpick<br/>method. A survey questionnaire was used in determining the anthropogenic activities,<br/>water quality awareness, and protection and conservation measures of residents in Ubihan<br/>River. For Class C water body, results showed that pH, biological oxygen demand, and<br/>nitrate levels in Ubihan River were acceptable for all the sampling months based on DENR<br/>standards, while temperature, total coliform, dissolved oxygen, and total reactive<br/>phosphorus did not meet DENR standards. The Water Quality Index in Ubihan River was<br/>unfit and deteriorated in all sampling months and all sampling locations. The abundance of<br/>Ligia sp. was significantly influenced by biological oxygen demand (r=.524, p=.045) in<br/>which they share a moderate positive correlation. Other physicochemical parameters of<br/>water did not exhibit a significant relationship with wharf roach abundance. To better<br/>preserve the ecosystem services of Ubihan River, an improvement in river management<br/>and protection is needed as well as a deeper understanding of the species present in the<br/>riverine ecosystem. |
