“…In terms of species richness, Lake Maragang harbors the highest value with a total of 7 species. This is quite close to the recorded freshwater fish species (11) in Lake Lakewood, Zamboanga del Sur by Superales et al (2013) and in the Lake Duminagat, Misamis Ocidental with a total of six species of fish fauna (Quimpang et al 2018). The Shannon-Weiner Diversity Index ('H) and Simpsons Dominance (D) in Mount Timolan Protected Landscape were found to be high with values of 2.59 and 1.02, respectively (Table 1).…”

“…The presence of non-indigenous species of P. reticulata in Upper Nilo stream may attribute a negative impact in the stream that may result to the possible decline of native freshwater fish species in the stream. As cited by Quimpang et al (2018), P. reticulata also known as guppy is considered as threat to native members of Cyprinids in United States (Sigler & Sigler, 1987). The species was also reported as a carrier of trematode parasites (Nico & Martin, 2001) and parasitic nematode (Eldredge, 2000) which may lead to high mortality rate of the native fish species in a riverine system.…”

In this study, research on the fish composition and abundance in the freshwater ecosystem of Mount Timolan Protected Landscape, Zamboanga del Sur, Philippines is presented. The Mount Timolan Protected Landscape is reported as a forest reserved because of its watershed importance. However, studies on fish fauna on its freshwater ecosystem have never been studied. Monthly sampling of fish fauna was conducted in the four established stations in the MTPL from December 2018 to May 2019 revealed a total of 2,422 individuals representing 12 species from 9 families. Shannon-Weiner Diversity Index (‘H) and Simpsons Dominance (D) was found to be high with values of 2.59 and 1.02, respectively. Interestingly, this study revealed an established population of native of species in Upper Nilo stream with no other introduced species found. Monitoring study is further recommended to evaluate the current status of the fish species of freshwater ecosystem of Mount Timolan Protected Landscape.

“…Whereas in downstream stations, open grassland with human settlements was observed and the river flow was leading to the open ocean. These observations contradict the study of Quimpang et al (2020) in the two rivers of Mt. Apo, where the temperature of upstream stations of the two rivers is much higher compared to their downstream stations.…”

Abstract. Dapar MLG, Lagumbay AJD, Parcon J, Tubongbanua Jr. RM, Amoroso VB. 2021. Assessment of fish species richness and physicochemical parameters of Mt. Hamiguitan Range Wildlife Sanctuary river systems in Mindanao, Philippines. Intl J Bonorowo Wetlands 11: 58-68. Being a UNESCO World Heritage Site, Mt. Hamiguitan Range Wildlife Sanctuary (MHRWS) is an exceptional area of diverse flora and fauna with conservation concerns. MHRWS river systems provide significant spawning and nursery grounds for freshwater fishes. However, anthropogenic activities may result in the degradation of fish habitats which calls for conservation. This study provides an updated assessment of the fish diversity of selected MHRWS river systems and recommends policies for the proper management of the rivers and riparian ecosystems. An inventory of fish species and an assessment of the physicochemical parameters were conducted in the three river systems of Mt. Hamiguitan Range Wildlife Sanctuary. A series of line transect of 100 m were established along the banks of the three rivers in three sampling stations (upstream, midstream, and downstream). Results showed that Dumagooc River has the highest number of fish species compared to Maug and Banahaw River. Generally, the species richness increased from upstream to downstream. The high species richness observed upstream and midstream is due to the presence of an intact forest with areas far from human disturbances. A total of 31 species in 11 families comprising 121 individuals were collected and identified. Of these, one endemic species, 29 native species and two introduced species were identified, representing 4.16% of 48 species recorded in the country. As to the physicochemical characteristics of the three river systems, the results showed that the temperature, pH, NTU and DO values of the sampling sites are within the minimum acceptable limit to be considered as within the standards for class AA, A, and B rivers.

“…Also known as the marbled eel, A. marmorata (Figure 5) is one of the most widely distributed freshwater eels in Southeast Africa, Asia, and Polynesia (Ege 1939;Marquet and Galzin 1991;Marquet 1996). It is considered one of the native freshwater eels of the Philippines and has been observed naturally in Ibulao River in Ifugao (Tauli et al 2022), Lake Duminagat in Misamis Occidental (Quimpang et al 2018), Bago River in Negros Occidental (Bucol et al 2010), and Cagayan River in Cagayan Valley (Piper et al 2022). The fishers in Lake Danao revealed that the peak season for A. marmorata is during the rainy seasons, particularly in October and November.…”

Lake Danao lies within the Lake Danao Natural Park in Ormoc City, Leyte, Philippines. The lake provides a habitat for various aquatic flora and faunal species. However, existing data on fish assemblage in Lake Danao is scarce and outdated. This study determined Lake Danao’s diversity, abundance, and local use of fish. With the help of local fishers, fish samples were collected from different parts of the lake twice a month for 14 months (March 2021 to June 2022). In addition, an ethnoicthyological survey was conducted to supplement the information on the provenance, endemism, and local use of the fish species in Lake Danao. This study recorded eight species of fish in Lake Danao, and only two are considered native (Anguilla marmorata and Clarias batrachus). Only five species were obtained from the fishers throughout the entire sampling period. On average, Glossogobius giuris was the most abundant species (95.96%), while Channa striata was the least (0.07%). The low Shannon-Weiner diversity index (mean = 0.19) and high Simpson’s dominance index (mean = 0.92) indicate low diversity and dominance of other species (e.g. G. giuris). No significant difference was observed in the diversity, dominance, and evenness of fishes between the sampling months. All of the fish species were used as alternative food sources. With the dominance of introduced species, local authorities are strongly encouraged to strictly regulate the entry, possession, and cultivation of exotic fish in Lake Danao and to continue the aquatic biodiversity assessment and monitoring in the area.
