Macrobrachium is one of prawn genera which has largest species number in family Palaemonidae, with some species of this genus being important commodity in aquaculture. Morphological characters for identification of this genus depend on environmental condition, growth phase, sex, and social dominance. This makes morphological identification on this genus quite difficult and tricky. Alternative approaches are required for better methods of Macrobrachium identification. DNA barcoding using 16S mitochondrial rRNA appears to be one promising method for Macrobrachium identification. This research aims to identify Macrobrachium from Tegenungan Waterfall using morphological and molecular analysis. Samples were taken from 4 sampling sites beneath the waterfall. All specimens were identified using several morphological identification methods. Specimen CR 07a and CR 10 were identified using molecular method. The molecular analysis utilized 16Sar (5'-CGCCTGTTTATCAAAAACAT-3') as forward primer and 16Sbr (5'-CCGGTCTGAACTCAGAT-CACGT-3') as reverse primer. From 11 specimens, 10 were identified as Macrobrachium. Specimen CR 07a was identified morphologically as M. horstii. According to BLAST analysis, specimen CR 10 was recognized as M. horstii with similarity up to 99% to GenBank specimens (JF310718.1 dan FM986616.1). Specimen CR 07a only reach 97% similarity to both GenBank specimens. Genetic distance analysis between specimen CR 07a and CR 10 assumed high genetic diversity, or even cryptic species indication in M. horstii population of Tegenungan Waterfall.

The objectives of this research include identifying the diversity of freshwater fish species. This research uses the literature method or literature review. Literature review is a comprehensive overview of the research that the number of freshwater fish species in Indonesia is approximately 1300 species. Literature studies can be obtained from various sources including journals, books, documentation, the internet and libraries. The literature study method is a series of activities related to library data collection methods, reading, and recording, and processing writing materials. The literature research method is related to the topic or variable of writing. There have been many studies conducted in Indonesia, but there is still little information related to freshwater fish diversity. This method focuses on the results of writing related to the topic or variable of writing. Based on research on the identification and diversity of fish species conducted in eight freshwater river locations, 33 fish species from 14 families were obtained. Generally, tropical Asian freshwater fish are dominated by the cyprinidae family. There are 33 species of fish from 14 families in freshwater rivers in Sunda exposure waters. 2 species of fish are threatened with extinction. The cyprinidae family is the most species found. Analysis of fish potential shows that there are 12 species of fish that have consumption potential, 11 species of fish that are endangered.

Deforestation will affect changes in the condition of the waters of the protected and secondary forest watersheds that can affect in it biota. Fish have limited ability to choose areas that are safe for their lives, especially the environment that is very supportive for the availability of food sources. The fish population in the Dong Sandar River and Rempangi as well as the diversity of fish species in both rivers is unknown. The problem of this research is how the diversity of fish species in the Dong Sandar River and Rempangi River, Sungai Laur District, Ketapang. Research on the diversity of freshwater fish species in the Dong River between the protection of protected forests and the Rempangi River in the secondary forest of Sungai Laur Subdistrict, Ketapang District, West Kalimantan consisting of 20 stations each of which there are 10 observation stations conducted on May 1-21, 2018. The selection of observation stations is selected (purposive sampling) which is based on consideration of the conditions and conditions of the aquatic environment. The results of the research were 884 individuals from 50 species of 18 families with the use of scattered, pukat, seluak, bubu, temilar, sauk , and ambe exploration tools. The most types of fish obtained on the Dong Sandar River and Rempangi River consist of the Cyprinidae family (20 species), Bagridae family (7 species), Siluridae family (4 species). The diversity of fish species in the Dong Sandar River and Rempangi River in Ketapang Regency is relatively moderate (H '<3) with a diversity index (H') of 2.94, if H '<1 means low diversity, if 1 <H' <3 means moderate diversity and if H '> 3 means high species diversity. The dominant index (C) on the Dong Sandar River is 0.09 while in the Rempangi River 0.11, the range of dominant index values is 0-1 if the value C = 0 means that there are no types of fish dominating and if C = 1 means there are other types of fish dominating. The highest evenness index (E) is found in the Rempangi River of 0.77 and in the Dong Sandar River 0.76, it can be seen the range of evenness of species index 0-1 if the value E = 0 means low type evenness, and if the value E = 1 means evenness is relatively evenly. The species richness index (R) of the Dong Sandar River has abundant types of fish with a value of 7.26 while in the Rempangi River only 4.40. Evenness on both rivers is 57.53%.
