“…However, despite their ecological significance, populations of many species of Sicydiinae are declining on a global scale, mainly due to unsustainable and illegal fishing practices (Devick et al 1995;Keith 2003a;Walter et al 2013). In addition, the entry of invasive species can cause the loss of local fish populations in Indonesia (Hasan et al 2019c;Hasan et al 2020a;Hasan et al 2020b;Hasan et al 2020d;Serdiati et al 2020).…”

Abstract. Hasan V, Valen FS, Islamy RA, Widodo MS, Saptadjaja AM, Islam I. 2021. Short Communication: Presence of the vulnerable freshwater goby Sicyopus auxilimentus (Gobiidae, Sicydiinae) on Sangihe Island, Indonesia. Biodiversitas 22: 571-579. A single specimen of freshwater goby Sicyopus auxilimentus was photographed and collected using fish traps between 8 and 15 September 2019 in the Laine waterfall, Sangihe island district, North Sulawesi Province, Indonesia. S. auxilimentus is amphidromous that live in both freshwater and marine environments. This species is currently listed as Vulnerable (VU) within the IUCN Red List Status. The specimen was identified as male S. auxilimentus based on the coloration of the preserved specimen: background yellowish; scale edges brown; posterior flanks and caudal peduncle orange; first dorsal fin black, second dorsal fin dusky black; pectoral fin slightly brown; ventral fin slightly dusky; anal fin blackish; caudal fin dusky brown. Specific morphological features were as follows: the base of the first dorsal fin was not connected to the second dorsal fin base; distance between the base of first and second dorsal fin was generally less than half of eye diameter; ventral fin rays were fused to belly only between fifth rays; posterior margin of caudal fins rays was rounded; scales were all ctenoid; scales appeared on the caudal peduncle, and between anal and second dorsal fins; anterior to which, scales became widely spaced and did not imbricate. Meristic characters were as follows: first dorsal fin rays VI; second dorsal fin rays I+9; ventral fin rays I+5; pectoral-fin rays 14; anal-fin rays I+9; caudal-fin rays 13; scales in lateral series 13; scales in zigzag series 7; scales in transverse series backward 7; scales in transerves series forward 4. This finding is considered the first record in Sulawesi and the fifth from Indonesian waters after findings in Halmahera, Java, Bali and Lombok. This record enhances the understanding of the distribution of S. auxilimentus in Indonesian waters. Monitoring is needed to assess the possibility of Sangihe Island being a growth ground, spawning ground, and/or on the migration route of S. auxilimentus. In the Laine waterfall, Sangihe island, freshwater conditions were as follows: salinity 3.5 psu, temperature 23-25°C, and dissolved oxygen 7.7-9.2 mg/l, which were ideal habitat for S. auxilimentus. S. auxilimentus from Sangihe Island, had 0.000 genetic distance than from S. auxilimentus from Bali, while the next closest genetic distance was S. zosterophorus at genetic distance of 0.090. In addition to onsite conservation, domestication programs are needed to increase commercial availability without depending on natural catches.

“…Further research, we suggest to applicate this method to other native or non-native fish that appear in Indonesian waters, such as Arapaima (Fadjar et al, 2019), Aligator gar (Hasan et al, 2020), Channidae (Pratama et al, 2020), Gobiidae (Hasan et al, 2021), Cichlidae (Insani et al, 2020), and Cyprinidae (Hasan et al, 2019).…”

Nemacheilus fasciatus is an Indonesian freshwater fish species that can be found in river waters on Java. This fish has a morphological similarity between species. This study aims to identify species of samples found and know their genetic kinship. This study used the Cytochrome Oxidase subunit I (COI) gene as a molecular marker, and then the results were analyzed using MEGA X software. The genetic structure and phylogeny of N. fasciatus sequences were combined with outgroup species from GenBank and analyzed using Maximum Likehood (ML), Pairwise Genetic Distance and Bootstrapping Phylogeny Model of Kimura 2 Parameters. The results showed that the primary pairs of LCO1490 and HCO2198 used to amplify the sample N. fasciatus with COI as a marker. The nucleotide frequencies of these loaches are A=26.5%, T=23.8%, C=19.9% and G=29.9%. The estimated Transition/Transversion bias (R) is 0.60. The number of haplotype diversity (Hd) was 0.972, and nucleotide (Pi) diversity was 0.05115. The kinship of N. fasciatus compared to the outgroup is closer to N. pallidus than N. chrysolaimos. Research needs to be conducted with a larger sample size for the genetic diversity of N. fasciatus in Indonesia.

The entry of foreign predatory fish into Indonesian open waters had the potential as a disease vector, predation, and damaging food webs that would have a systemic impact on the local ecosystem. In this study, we report the presence of the foreign predatory fish Jaguar cichlid Parachromis managuensis (Günther, 1867) from Central America in the Lingsar River, West Lombok Regency. This record is the first time for this species in Lombok, where previously this fish was found in Java. A description of the morphological characters of the captured specimens is provided in the discussion.
