IKTIOFAUNA PERAIRAN TAWAR DI KAWASAN TAMAN NASIONAL BOGANI NANI WARTABONE DAN SEKITARNYA, GORONTALO-SULAWESI UTARA

ABSTRACT TNBNW is included in the Wallacea Region which is a transitional zone between Oriental and Australian zoogeography which is estimated to have many unique and endemic flora and fauna species, including fish species that have not been fully disclosed. This study aims to inventory the diversity of ichthyofauna that live in the fresh waters of the TNBNW area and its surroundings. Sampling was carried out by making 11 research stations from the waters that flow from the Matabulawa peak to the Bone River. Samples were collected by electrofishing then identified and preserved using formalin solution. The species of fish obtained were analyzed on the index of diversity, evenness, and species richness. To complete the data, tabulation of data on fish species in the TNBNW area from previous studies as well as specimens that already have catalog numbers deposited in MZB was carried out. This study found 13 species of fish consisting of 6 families and 10 genera. The total ichthyofauna in the TNBNW area and its surroundings is 32 species consisting of 15 families. Stiphodon sp. is the species that has the highest relative abundance (48.80), followed by Poecilia reticulata (11.00). The species with the highest local distribution was Belobranchus belobranchs (90.91%). The rivers that have the highest index of species diversity, evenness, and species richness are Pilolode River, Pilohampaa River, and Loji River, respectively. Two species are classified as introduced fish, namely Poecilia reticulata and Oreochromis niloticus. Several species of fish have potential as ornamental fish as well as consumption fish. Key words: Species diversity, ichthyofauna, TNBNW ABSTRAKTNBNW termasuk ke dalam Kawasan Wallacea yang merupakan zona peralihan antara zoogeografi Oriental dan Australia yang diperkirakan memiliki banyak jenis flora dan fauna yang unik dan endemik, termasuk jenis-jenis ikan yang belum semua dapat diungkapkan.

Distributional mapping and impacts of invasive alien fish in Indonesia : an alert to inland waters sustainability

Inland water ecosystems in Indonesia face an increasing threat of alien and invasive alien fish species. Their existence have been found in Indonesian waters since before 1900, and their introduction is rapid and ongoing. In this review, we mapped the distribution of alien and invasive alien fish in different inland waters ecosystem types and islands in Indonesia, based on available literature indexed by Google Scholar. Impacts of invasive alien fish and how to control them are also discussed. This data mining exercise resulted in the successful mapping of alien and invasive alien fish in 72 lakes and 57 river systems, covering 28 provinces. A total of 50 species have spread with different compositions in each type of ecosystem and island. Oreochromis niloticus is the most commonly encountered alien species. Moreover, invasive cichlid fish are most frequently found in lakes, while Pterygoplichthys spp. are more frequently found in rivers although they can also inhabit many lakes. Java Island is a hotspot of alien and invasive alien fish distribution, with 39 species reported. Invasive alien fish harm native and endemic fish in Indonesia through competition for food, space and direct predation. The gradual reduction of established populations of invasive alien species is necessary to protect Indonesia’s freshwater ecosystems

Disentangling the taxonomy of the subfamily Rasborinae (Cypriniformes, Danionidae) in Sundaland using DNA barcodes

Sundaland constitutes one of the largest and most threatened biodiversity hotspots; however, our understanding of its biodiversity is afflicted by knowledge gaps in taxonomy and distribution patterns. The subfamily Rasborinae is the most diversified group of freshwater fishes in Sundaland. Uncertainties in their taxonomy and systematics have constrained its use as a model in evolutionary studies. Here, we established a DNA barcode reference library of the Rasborinae in Sundaland to examine species boundaries and range distributions through DNA-based species delimitation methods. A checklist of the Rasborinae of Sundaland was compiled based on online catalogs and used to estimate the taxonomic coverage of the present study. We generated a total of 991 DNA barcodes from 189 sampling sites in Sundaland. Together with 106 previously published sequences, we subsequently assembled a reference library of 1097 sequences that covers 65 taxa, including 61 of the 79 known Rasborinae species of Sundaland. Our library indicates that Rasborinae species are defined by distinct molecular lineages that are captured by species delimitation methods. A large overlap between intraspecific and interspecific genetic distance is observed that can be explained by the large amounts of cryptic diversity as evidenced by the 166 Operational Taxonomic Units detected. Implications for the evolutionary dynamics of species diversification are discussed
