Rivers serve as a habitat for a variety of species such as Jagora Asperata, locally known as Tabagwang, in which they live and survive everyday. Due to extensive water pollution, people are at risk in consuming food from the polluted river. The researchers came up with the study, aimed to determine the physicochemical and microbiological properties of water and relate to the bacteria that are present in the gut of the Tabagwang that are both gathered in Barangay Oliva (Basud), Barangay Daculang Bolo (San Lorenzo Ruiz), and Barangay Man-ogob (San Vicente).

 

In the mentioned order of the locations, the results in terms of physicochemical and microbiological properties that are tested at Bureau of Fisheries and Aquatic Resources Region V, concerning the pH level, resulted in 6.93, 6. 80, and 6.73. With regards to TDS, it comes up to 44.86ppm, 55.25ppm, and 90.3ppm. As to temperature, it yielded a result of 30℃, 27.8℃ and 28.3℃. In connection with dissolved oxygen, comes up to an end of 5.32ppm, 4.78ppm, and 4.61ppm. Lastly, electrical conductivity resulted in 76.5Us/cm, 90.3Us/cm and 120.9Us/cm. The Escherichia coli (E. coli) count was measured at 40MPN/100mL, 48MPN/100mL, 170MPN/100mL. Last, the fecal coliform resulted in the same amount, more than 1600. 

 

As to microbial gut testing, E. coli count derived to 15MPN/g, 7.4MPN/g and 240MPN/g. Lastly, in terms of Staphylococcus aureus, all locations resulted in more than 10cfu/g. These are tested at BFAR National Laboratory.

 

In conclusion, there was a significant relationship between the two samples, it can be implied that there is a likelihood that an E. coli is present in a gut of the species once present or has a high concentration in water. Once a species is consumed, there is a high risk for diseases
