This research aims to study the diversity of biological resources in the waters of the University District, including fish, insects, algae and phytoplankton. In inland areas, nature trail. University District And to study water quality in some inland areas, nature trail. University District The collection of the specimen. The water area of the Trail. University District Huai Thap Chang 3 points, collected aquatic insects using visual, sweep net, kick and pick method in water and backwater areas with fallen leaves and branches. The comprehensive nature of resident aquatic insects each for five minutes, collecting samples of algae and plankton from the water sources in the area, nature trail. University District No. 3 spot in the creek water over the elephants, the water flow. Using the same sampling fish. And water samples from the Trail. University District Huai Thap Chang holds the number three spot in the middle of the water at a depth of 30 cm by 30 cm deep water collected at the study found that a variety of fish in the water. Local nature trail University District All nine families showed that 11 fish species found in 12 currencies family Cyprinidae (carp), most of the three types of Barbonymus gonionotus (carp), Cyprinus carpio (carp) and Pethia Stoliczkana
(Pla Ma Fai), followed by family. Luciocephalinae (trichopodus) found two types Trichopodu mcrolepis (moonlight gourami) and Trichopodus trichopterus (three spot gourami) where tilapia (Oreochromis niloticus) is the dominant species. It was found in all the samples and found many. The design and nature trail show what kind of fish are found. And the water quality did not differ significantly between water resources are. The amount of dissolved oxygen, BOD acidic - pH and temperature factors are the difference between a water source such as ammonia, nitrite, nitrate, phosphate, alkalinity, hardness, conductivity, carbon dioxide release, turbidity factor no. the difference between the samples are. The amount of dissolved oxygen, ammonia, nitrite, nitrate, hardness and conductivity. Factors difference between the time samples were BOD acidic - pH, alkalinity, phosphate, temperature and turbidity assessment of water quality with the Water Quality Index showed that water quality are the reservoir page. dormitory Wiang Phayao And periods of low water quality are November.
