Due to the development needs of Tien Hwa Hu Reservoir, EIA Report was completed and submitted for review. The EIA Committee of EPA has decided on its 201th meeting to “conditionally approve the EIA review”. In 2015, “The Plan of Water Environmental Observation and Investigation in Houlung River (II) - The Investigation and Assessment of Rivulet Ecology Conservation (2/2)” has suggested to continuously monitor the ecology of Houlung River Basin, and thus 3 sample stations of Houlung River (Dalukeng, Jhuangoushuei, and Jin-gua Bridge) and 3 sample stations of Shahe Creek & Feifong Creek (Shahe Bridge, Nan-Pei Bridge, and Shuang-Fong Bridge) were selected. otally 25 species of 2,580 fishes from 11 families of 4 orders were recorded in the sample stations. 11 species of them are dominant species, which include Acrossocheilus formosanus, Candidia barbata, Microphysogobio alticorpus, Formosania lacustre, Opsariichthys pachycephalus, Opsariichthys evolans, Hemimyzon formosanum, Rhinogobius candidianus, Spinibarbus hollandi, Leiocassis taiwanensis, and Rhinogobius rubromaculatus. According to “Taiwan Freshwater Fishes Redbook”, Paracheilognathus himantegus, Hemibarbus labeo and Opsariichthys evolans belong to “Class D Nearly Endangered” protected species. In the records, Rhinogobius giurinus, Sicyopterus japonicas, Kuhlia marginata, Rhyacichthys aspro and Anguilla marmorata are migratory species; Oreochromis sp., Channa striata, and Spinibarbus hollandi belong to alien species. This year, totally 5 species 1,525 crustaceans from 4 families were recorded. The dominant species are Macrobrachium asperulum, accounting for 91.02% of overall investigation amount. 1 species belong to migratory Decapoda animals, which are Eriocheir hepuensi. They were found around the reservoir and can be traced back to the sample station of Shahe Bridge. Neocaridina ketagalanare , and Candidiopotamon rathbunae are two dominant species.
