Abstract: ERCE, ANGELICA T. and QUINONES, ALYSSA MAE A. Identification of Fish and Crustacean Species and Water Quality Assessment of Caiias River Watershed, Cavite, Philippines. Undergraduate Thesis. Bachelor of Science in Environmental Science. Cavite State University, Indang, Cavite. May 2017. Adviser: Ms. Amyel Dale L. Cero. The study was conducted in Cafias River Watershed, one of the six major watersheds in Cavite province, which traverses three cities, and four municipalities: Tagaytay City, Amadeo, Indang, Trece Martires City, Tanza, General Trias City, and Rosario. The study was conducted from May 2016 to February 2017 to assess the fish and crustaceans species of the watershed. The general objectives were to identify the fishes and crustaceans and assess the water quality of the Cafias River Watershed. Specifically, it aimed to: (1) identify fish and crustaceans present within the rivers of Cafias River Watershed; (2) determine the physico-chemical properties of water in terms of temperature, pH, dissolved oxygen (DO), salinity, conductivity, and total dissolved solids (TDS); (3) determine the problems and issues that are currently being faced by the rivers within Cafias River Watershed; and (4) identify the policies and conservation measures that are being implemented by the local government units within Cafias River Watershed. Ocular visits in the sampling areas were conducted in order to assess the areas for the collection of fish, crustaceans and water samples. Eleven (11) sampling Stations were established to gather the relevant data. For the physico-chemical properties of Cafias River Watershed during the wet season, pH ranged from 6.39 to 8.08; DO ranged from 0.4 to 7.53 mg/L; temperature ranged from 24.3 to 30.9 °C; conductivity ranged from 18.69 to 458.67 us/m; salinity ranged from 9.36 to 239.33 ppm; and TDS ranged from 12.96 to 329.33. For the dry season, pH ranged from 7.25 to 8.04; DO ranged from 3.79 to 16.57 mg/L; temperature ranged from 23.27 to 27.73 °C; conductivity ranged from 5.81 to 361.33 ps/m; salinity ranged from 4.46 to 225.33 ppm; and TDS ranged from 6.34 to 301.33. The study identified 23 fish species and seven (7) crustacean species. Out of the 23 fish species identified, 13 were indigenous and 10 species were classified as introduced. On the other hand, there were two (2) species of crustacean identified as indigenous, while five (5) were introduced among the seven (7) identified species of crustaceans. The most common problems in Caiias River Watersheds, as reported by the barangay secretary/officials and local fisherman, are improper solid waste disposal, lack of proper septic tanks and sewage canal of households in the downstream area that can directly affect the quality of the river which can lead to poor water quality. Also, there are cases of illegal fishing using sodium cyanide in the last few years that greatly reduced the population of aquatic species in the rivers. The environmental policies that are being implemented at the Local Government Units (LGUs) within the watershed is the R.A 9003: Ecological Solid Waste Management Act of 2000, under which proper waste segregation is required. Other environmental programs include tree planting every year or quarterly and clean up drive.

The study was conducted in Cafias River Watershed, one of the six major watersheds in Cavite province, which traverses three cities, and four municipalities: Tagaytay City, Amadeo, Indang, Trece Martires City, Tanza, General Trias City, and
Rosario. The study was conducted from May 2016 to February 2017 to assess the fish and crustaceans species of the watershed. The general objectives were to identify the fishes and crustaceans and assess the water quality of the Cafias River Watershed. Specifically, it aimed to: (1) identify fish and crustaceans present within the rivers of Cafias River Watershed; (2) determine the physico-chemical properties of water in terms of temperature, pH, dissolved oxygen (DO), salinity, conductivity, and total dissolved solids (TDS); (3) determine the problems and issues that are currently being faced by the rivers within Cafias River Watershed; and (4) identify the policies and conservation measures that are being implemented by the local government units within Cafias River Watershed. Ocular visits in the sampling areas were conducted in order to assess the areas for the collection of fish, crustaceans and water samples. Eleven (11) sampling Stations were established to gather the relevant data.

For the physico-chemical properties of Cafias River Watershed during the wet season, pH ranged from 6.39 to 8.08; DO ranged from 0.4 to 7.53 mg/L; temperature
ranged from 24.3 to 30.9 °C; conductivity ranged from 18.69 to 458.67 us/m; salinity ranged from 9.36 to 239.33 ppm; and TDS ranged from 12.96 to 329.33. For the dry season, pH ranged from 7.25 to 8.04; DO ranged from 3.79 to 16.57 mg/L; temperature ranged from 23.27 to 27.73 °C; conductivity ranged from 5.81 to 361.33 ps/m; salinity ranged from 4.46 to 225.33 ppm; and TDS ranged from 6.34 to 301.33.

The study identified 23 fish species and seven (7) crustacean species. Out of the 23 fish species identified, 13 were indigenous and 10 species were classified as introduced. On the other hand, there were two (2) species of crustacean identified as
indigenous, while five (5) were introduced among the seven (7) identified species of crustaceans.

The most common problems in Caiias River Watersheds, as reported by the barangay secretary/officials and local fisherman, are improper solid waste disposal, lack of proper septic tanks and sewage canal of households in the downstream area that can directly affect the quality of the river which can lead to poor water quality. Also, there are cases of illegal fishing using sodium cyanide in the last few years that greatly reduced the population of aquatic species in the rivers.

The environmental policies that are being implemented at the Local Government Units (LGUs) within the watershed is the R.A 9003: Ecological Solid Waste Management Act of 2000, under which proper waste segregation is required. Other environmental programs include tree planting every year or quarterly and clean up drive.
