“…In addition, Kelabau from the Siak and Rokan rivers were designated as one sub-sub group in group two ( Figure 4) because both rivers are geographically connected, allowing for hybridisation, whereas, there is inbreeding of these fish in the Kampar River, which causes a nucleotide diversity value of 0.0. Geographically, these three rivers (Siak, Kampar and Rokan rivers) have different environmental condition, that cause variations in morphology in fish (O. melanopleurus) based on truss morphometric 42 . Factors causing morphological variations are environmental differences, habitat pollution levels, long-term isolation and crossbreeding in populations 43,44 .…”

Background: Kelabau (Osteochilus spp.) is a freshwater fish commonly found in the rivers of Riau, Indonesia. Researchers believe that these are Osteochilus kelabau; however, accurate taxonomic determination of these fish in Riau waters has not been made. The purpose of this study was to facilitate the identification of the kelabau based on its morphology and genetics using biometric and cytochrome c oxidase subunit 1 (CO1) analyses, respectively. Methods: Fish samples were collected from the Siak, Kampar and Rokan rivers in Riau Province, Indonesia. The DNA of 90 fish was extracted from the caudal fins using a DNA extraction kit, after which it was amplified using primers Fish-F1 and Fish-R1. Sequencing was conducted by Applied Biosystems Macrogen Korea, and the DNA sequences were then edited and aligned using MEGA v. 7. All samples were BLAST-searched for identification using the National Center for Biotechnology Information and BOLD System. Phylogenetic trees were constructed, and the similarity index was calculated using accession numbers AP011385.1 and KC631202.1 in GenBank. Results: Analysis of the consensus barcode sequence for 86 species revealed a high percentage of barcode matches (96%–97% in GenBank and 96.6%–96.76% in the BOLD System). The nucleotide distance between groups of kelabau from the different rivers based on the Kimura 2-parameter model gave the following results: 0.05% between groups from the Siak and Kampar rivers, 0.09% between those from the Siak and Rokan rivers and 0.05% between those from the Kampar and Rokan rivers. The nucleotide distance between the groups in the Siak (0.09%), Kampar (0.00%) and Rokan (0.10%) Rivers indicated that the kelabau in those rivers were related to each other. Conclusions: Based on the results of the research data using CO1 and biometric analyses, the kelabau were confirmed to be O. melanopleurus.

“…The pH of the waters of the Koto Panjang Reservoir is between 5-6 means that the river water has a normal acidity. Asiah [17] said that in acidic water conditions, heavy metal ions are released into the waters, especially Cd++ and Pb++++ ions which are irritant and toxic to aquatic biota, including fish. Fish that live in it.…”

Water quality monitoring activities are important to be carried out regularly. This activity is intended as an effort to create sustainable cultivation activities. The Koto Panjang Reservoir is one of the reservoirs used for aquaculture activities, so monitoring activities at this location are important things to do. This activity was carried out using a survey method at two observation locations. Location 1 is the floating net caged area, and Location 2 is the upstream or non-floating net cages area. Direct water quality measurements were carried out in both locations: temperature, pH, and DO. In addition, water samples were taken to see the content of heavy metals, namely Cd and Pb. Water samples were carried out to see the heavy metal content at the Basic Chemistry Laboratory, Faculty of Engineering, Riau University. The results showed that overall, the physicochemical quality of water at the Koto Panjang Reservoir, both Locations 1 and 2, namely temperature, dissolved oxygen, and pH, still met the requirements for fish farming. While the value of Cd in all observation locations at the Koto Panjang Reservoir exceeds the quality standard, it can be said to be polluted. Unlike Cd, there is a difference in the value of Pb at Location I and II, namely Pb at Location I; the Pb value is outside the quality standard threshold or is said to be polluted, while Location II still has not exceeded the quality standard. The high Pb value at Location I was due to many fishing boat activities with engines.

“…The fusiform body shape tends to be elongated and allows fish to swim fast because it minimizes friction with water (Kilawati and Arfiati 2017). Asiah et al (2018) stated that the emergence of meristic characters is based on genetic factors. The environment can cause a modification of the meristic character.…”

Abstract. Anitasari S, Arfiati D, Susilo, Marhendra APW. 2024. Morphological characteristics of sex dimorphism in Gobiopterus sp. (Gobiiformes: Oxudercidae) from Ranu Grati Lake, Pasuruan District, East Java, Indonesia. Biodiversitas 25: 1214-1222. Ranu Grati is a volcanic lake located in Pasuruan, East Java, Indonesia which has high ecological value as a habitat for a unique endemic fish found only in this lake, namely the Lempuk fish (Gobiopterus sp.). The aim of this research is to determine the morphological characters based on sexual dimorphism of Lempuk fish. in Ranu Grati Lake. The result showed the body color of male and female Lempuk fish is transparent. Lempuk fish do not have sexual dichromatism or their sex cannot be distinguished based on their body color. Lempuk fish have vomer teeth and canine teeth. Types of male and female ctenoid scales have a comb-like shape. The position of the mouth of the Lempuk Fish is located near the top or head of the fish but not precisely at the tip. There are variations in the superior subterminal mouth type between male and female fish, especially in terms of anatomical details and mouth structure. Based on meristic observations of the Lempuk fish, it can be explained that this fish has a fusiform body shape, this shows that gobies generally have a small fusiform body and also has pectoral fins, pelvic fins, dorsal fins, tail fins and anal fins. In this study, we found from histological observations of the Lempuk fish, mature oocytes and spermatids were found in one histological tissue sample at male fish with gonad maturity level II. This change from female to male occurs at the size of the fish with fish size of 21.21-30.58 ± 2.14mm. It indicates that is Lempuk fish is a species hermaphrodite protogyn.
