Ichthyofauna of Fakfak, Papua – Indonesia

Fakfak and Kumawa Mountains are located in Bomberay Peninsula, Papua, a poorly known ichthyological record and was recommended by Conservation International for field inventory. This research was conducted from 6-15 February 2021 to document freshwater fish diversity in northern and eastern Fakfak toward Bomberay District. The fish was collected from creeks, streams, and rivers. The fish collection was done once in each location, mainly using a seine net, while a gill net was used in a few sites along Ubadari River. It was done for four hours, netting in one to three locations each day. Fish abundance was described based on common (C), occasionally (O), dan rare (R) scales. Freshwater fish data were descriptively identified. Twenty-two native New Guinean species belonging to 19 genera and 14 families were collected during the survey. There was no specific family dominant in the fish community. All fish recorded have widespread distribution, yet only one species has restricted distribution in the Vogelkop and Bomberay Peninsulas. One rainbowfish species was observed but not properly identified. This results as initial data of the fish community of Bomberay Peninsula, especially of Fakfak. Further research is needed to reveal the fish community from another part of the peninsula.

Abstract. Suryaningsih S, Bhagawati D, Sukmaningrum S, Sugiharto, Puspitasari IGAAR. 2020. Freshwater fish diversity in three tributary streams in Serayu Basin, Central Java, Indonesia. Biodiversitas 21: 5811-5817. Determining the diversity of freshwater fish species in Central Java, Indonesia has been confounded by temporal and spatial limitations in past studies. The Serayu Basin is a large watershed in Central Java that is believed to have high freshwater fish diversity. We aimed to determine the diversity and community structure of freshwater fish species in three tributaries of the Serayu, elucidate the factors influencing this diversity, and determine the extent to which these tributaries contribute to the total freshwater fish species richness for southwest Central Java. We conducted gill net sampling from May to August 2018 on the Tulis, Mrawu, and Kali Sapi Rivers located at Banjanegara district Sampling followed a random group technique in upstream, midstream, and downstream river sections of each tributary. In total, we observed 21 freshwater fish species. Broadly, fish species diversity was relatively low in the study area, and water temperature and dissolved oxygen were important in maintaining fish diversity. These three tributaries house 27–46% of the freshwater fish species reported for southern Central Java.

Abstract Freshwater fish diversity, abundance, the ecological indices, and water quality from Main Outfall Drain (MOD) in Al-Diwaniya City/middle Iraq were studied monthly from January to December 2017 in two sites. The present study has shown that the third river (MOD) supported 15 fish species belonging to 7 families. As far as biodiversity status in fish community (IUCN-2019) is concerned, out of 15 species, eleven fish species are categorized into Lower risk least concern (LC or LR/lc), four Vulnerable (VU). Eight species were sensitive to salinity; seven species were tolerance. The results were concluded that the properties of water were tolerable for the fish community. Ultimately, it can be concluded that the sector of MOD supported the fish community. But it needs constant monitoring for the conserve and development of the diversity and the case of the healthy fish.

Fish Collection

Geologically southern part of New Guinea Island is the oldest part of the mainland and have most speciose of freshwater fish. Asmat is one area in Southern New Guinea where has some large river systems such as Siret and Vriendschap Rivers. There is not much information on freshwater fish diversity of the area. This study aim to know freshwater fish species of both river systems, in order to manage the area as conservation area by local government. Active fish collection method was applied to sample fish of Siret and Vriendschap River Systems. One seine net, 3.6 m length, 1.23 m in height, and with a mesh size of less than 0.5 cm, and traditional scoop net were used to collect fish. The Siret and Vriendschap freshwater fish fauna consist of 22 species in 18 genera and 15 families. Cochlefelis danielsi (Ariidae), Mogurnda cingulata (Eleotridae), Zenarchopterus novaeguineae (Hemiram-phidae), Melanotaenia ogilbyi (Melanotaenidae), Synaptura villosa (Soleidae) are endemic to Southern New Guinea. Spesifically, Mogurnda cingulata (Banded Gudgeon) and Melanotaenia ogilbyi (Ogilbyi’s Rainbowfish) have restricted distribution in Southern New Guinea. Further research in smaller stream and its tributaries might increase freshwater fish diversity of Asmat.Key words: Southern New Guinea, Asmat, freshwater fish

Cipanas River is one river in West Java where its upstream region in Tampomas Mountain, Sumedang and it is emptied into the Java Sea, Indramayu. The study was aimed to investigate fish diversity in the downstream area of Cipanas River. The study was conducted by survey methods with census data collection techniques, taken place at 3 stations of Santing, Tempalong, and Cemara of Indramayu Regency. The parameters measured consisted water quality and fish assemblages. Water quality was measured referring to standard laboratory protocol, and fish collection was made by case net with different mesh sizes. The results showed that water quality conditions of the Cipanas River downstream was suitable for inhabiting fishes. There were as many as 548 individual fishes caught belonging to 21 species, 16 genera, and 14 families. Fish diversity was categorized as medium with 1.6 ≤ H ’≤ 2.2 indicating fairly good community structure, and the Evenness index was 0.81 ≤ E ≤ 0.86 to show highly evenly distributed.

Fish Samples

The study evaluated the fish community assemblage in the sections of the Subri river, the Ankobra river, and the “galamsey” pond within the Prestea community as impacted by alluvial mining activities. Gill nets of length 10 m and mesh size 1.27 cm were used to trap fish of average length 25.25 cm whilst cane baskets were used to trap fish of average width 10.40 cm using the catch and recapture method. All the 46 fish samples identified belong to 10 genera and 5 families. The Chichlidae was the dominant family, accounting for 60% of the total families observed. With an H’ index of 1.57 the Subri river had the most fish diversity in comparison with the Ankobra river and the “galamsey” pond, which had 1.21 and 0.71, respectively. Similarly, the Subri river had a more complex fish community structure than the Ankobra and “galamsey” pond. The dominant species, Oreochromis niloticus, has not yet been evaluated by the IUCN, but the least dominated Brienomyrus brachyistus could be regarded as “least concern”. Notwithstanding, these fish are essential for food by the local communities. There is a possibility that the alluvial mining might have influenced the complexities of fish species communities. Thus conservation efforts must be promoted to sustain fish communities and overall freshwater ecosystem health.
