“…Gastropods are one of the most common groups of mollusks found in various substrates due to their high malleability compared to other classes on rigid and smooth substrates (Turra and Denadai 2006;Baharuddin et al 2018;Islamy and Hasan 2020). Wildan et al 2021 report that Gastropod becomes the most abundant taxa in Batang Toru River because of its wide adaptability and tolerance to environmental conditions. However, Gastropods are composed of many species, and their spatial distribution is determined by particular living habitats, certain areas, and certain times .…”

Abstract. Kadim MK, Pasisingi N, Alinti ER, Alinti ER, Panigoro C. 2022. Biodiversity and community assemblages of freshwater and marine macrozoobenthos in Gorontalo Waters, Indonesia. Biodiversitas 23: 637-647. Macrozoobenthos plays an essential role in the aquatic ecosystem including as primary consumers, food sources, and water quality bioindicators. This study aimed to determine the composition, taxa abundance, community structure of the macrozoobenthos in the lower reach, estuary, and marine areas along Gorontalo waters, also their association with water quality parameters. Biota samples were collected purposively from 33 sampling points. The sampling process was conducted in June 2020 and May 2021. Macrozoobenthos samples were taken using Ekman Grab and prepared with filters (mesh size of 500 µm). Statistically, a t-test was done to assess the significance of taxa abundance difference among three different ecosystems from both sampling periods. Similarity percentages were displayed through a dendrogram. Furthermore, the biota assemblages and water quality parameters association were interpreted through Eigenvalues of Principal Component Analysis using Minitab ver. 14.0. The results showed that the macrozoobenthic community structure composed 70 taxa belonging to six classes dominated by Gastropoda, followed by Bivalvia, Malacostraca, Clitellata, Polychaeta, and Polyplacophora. The marine area had the highest abundance of macrozoobenthos (469.5 ind. m-3 in 2020; 460.9 ind. m-3 in 2021), followed by the river station (335.3 ind. m-3 in 2020; 2621 ind. m-3 in 2021), and estuary zone (217.3 ind in 2020. m-3; 848.5 ind. m-3 in 2021). The most abundant species in the lower reach area was Melanoides sp. (135.5 ind. m-3 in 2020; and 1222.5 ind. m-3 in 2021), while in the estuary was Brachidontes sp. (70.7 ind. m-3 in 2020; and 248 ind. m-3 in 2021). Batillaria sp. (128.3 ind. m-3 in 2020) and Anachis sp. (1510.7 ind. m-3 in 2021) were the species with the highest number in the marine zone. Based on the diversity and evenness index, the sea was in the medium category with no dominant species in the marine area. Biota communities in the lower reach station tend to be more like estuary biota than marine biota.

“…These changes are like changes in the function of the watershed, which was originally an area to accommodate, store and drain water from rainfall and then flow it into rivers, becoming residential and agricultural areas [3]. If this happens in many watersheds, it will cause a decrease in water quality [4,5,6,7]. Based on this, it is necessary to conduct research related to the physics and chemistry of water and the biology of eels in the Cicatih and Citaik rivers, Sukabumi, West Java.…”

Land changes around the Citarik and Citatih rivers will affect the water quality. These changes will affect eels’ life (Anguilla spp.) as fish that live in the area. This study aimed to determine water quality (physical and chemical) and the presence of eels (Anguilla spp.) in the Citarik and Citatih rivers in the Cimandiri watershed Sukabumi, West Java. This research was conducted from April to May 2021. Data collection was carried out in the upstream, middle, and downstream areas of the Citarik and Cicatih rivers. The results of this study show that the Ciratik river has a turbidity of 53.3-93.6 NTU, current 0.448-0.478 m/s, temperature 25.55-26.65 °C, TDS 0.002 0.041 mg/l. Eels caught amounted to 13 individuals of (Anguilla Marmorata); Cicatih river had a turbidity 84.4-264 NTU, current 0.142-0.814 m/s, temperature 26.76-29.05 °C, TDS 0.079-0.096 mg/l, and eels caught amounted to 12 individuals of (Anguilla Marmorata). Based on the results, environmental changes in the Citarik and Citatih rivers are still normal, as evidenced by the water quality that is still following the needs of the eels and the presence of eels.

Development potential of native fish in Batang Toru Watershed, North Sumatra, Indonesia: discussion on the impact of dam development and aquaculture efforts

As one of the sizable rivers in the Sumatra region, the Batang Toru River is a habitat for various fish species, some of which are potential to be developed as cultured fish. This study was carried out in April, July, and October 2019 in the Batang Toru River watershed of South Tapanuli Regency, North Sumatra, to evaluate a potential development of the riverine fish for aquaculture development. The methods used were fisheries surveys and discussions with various communities and related agencies in the South Tapanuli Regency. The data obtained were presented descriptively. Based on the result of data analysis collected in the field, there were several potential fish species to be cultured in this study, including mahseer (Tor tambroides, T. tambra, Neolissochilus soro), catfish (Hemibagrus spp.), and eel (Anguilla bicolor). Some people in the area have also developed the culture of several fish species, such as mahseer and catfish. However, there has been no eel rearing until now, although some locations around the Batang Toru River are suitable for freshwater fish aquaculture activities.
