Abstract. Hidayani AA, Fujaya Y, Trijuno DD, Rukminasari N, Alimuddin A. 2020. Genetic diversity of blue swimming crab (Portunus pelagicus Linnaeus 1758) from Indonesian waters (Sunda and Sahul Shelf, Wallacea region): Phylogenetic approach. Biodiversitas 21: 2097-2102. Blue swimming crab is one of the exploited fisheries commodities in Indonesia. This condition has contributed to the decline of their genetic diversity. The information on genetic diversity assumes importance for the conservation and the cultural purposes of species. The study aimed to determine the genetic diversity of blue swimming crabs from Indonesian waters using phylogenetic analysis. We conducted sampling of crab from several Indonesian waters, such the Aceh and Semarang (representing Sunda Shelf), Barru, South Sulawesi, and Maumere, Flores (representing Wallacea region) and Sorong, Raja Ampat and Kaimana (representing Sahul Shelf). Genetic diversity in this study using mitochondrial DNA (mtDNA) by implementing the method of Cytochrome c Oxidase Subunit I (COI). According to the findings, the blue swimming crabs from our study sites had a high genetic diversity variation. Three groups of crabs were determined using phylogenetic tree which formed three different unique clades. There was the same haplotype of crab observed from different locations, barring a sample from the Sahul Shelf which has a unique haplotype. There was no genetic speciation of crab samples from the Sunda Shelf and the Wallacea region were observed, except samples from the Sahul Shelf. Hybridization might occur between species of the crabs due to the finding of a cryptic species.

Abstract. Hasanah U, Binawanto, Alimuddin A, Boediono A, Kursini E. 2020. Short Communication: Effect of cryopreservation on ultrastructure and mitochondrial function of albino Pangasius catfish spermatozoa. Biodiversitas 21: 4524-4528. Cryopreservation techniques have been carried out on many endangered species and animals with unique characteristics. Successful cryopreservation techniques vary between species depending on various factors. The study used cryopreserved spermatozoa of the albino Pangasius catfish as samples. The cryopreserved spermatozoa were analyzed by its ultrastructure, functional mitochondria, and viability. The cryopreservation was performed using a combination of 10% methanol, skim milk, and fish ringer extender. A deep freezer is used for cryopreservation at -80 °C with a storage period of 14 days. Observations were made on fresh spermatozoa, post-equilibration spermatozoa, and frozen-thaw spermatozoa. This study found there were differences in ultrastructure and morphology in the three treatments. Fresh spermatozoa and post-equilibration spermatozoa appeared intact membrane, mitochondrial, and flagellar structures. In contrast, in frozen-thaw spermatozoa, there was damage to the cell membrane. The study showed different percentages of yields on functional mitochondria of fresh spermatozoa (98 ± 2%), spermatozoa post-equilibration (57 ± 7%), frozen-thaw spermatozoa (42 ± 3.21%). Cell viability showed that there were differences in viability of fresh spermatozoa and frozen-thaw (p <0.05), the results of fresh spermatozoa (92 ± 0.57%) spermatozoa post-equilibration (80 ± 3.51%), frozen-thaw spermatozoa (61 ± 2.30%).The study concluded that the spermatozoa cryopreservation affects the ultrastructure, mitochondrial function, and viability in albino Pangasius catfish spermatozoa.

Abstract. Sari DN, Nasrullah H, Ekasari J, Suprayudi MA, Alimuddin A. 2021. Sequence and expression analysis of glucokinase mRNA from herbivorous Giant gourami (Osphronemus goramy). Biodiversitas 22: 741-750. Glucokinase (GCK) is one of the enzymes that play important roles in carbohydrate metabolism and high glucose homeostatic in fish. The information about the GCK mRNA sequence and its expression is limited in Giant gourami, one of the most important herbivorous aquaculture species in Indonesia. The present study aimed to characterize the GCK mRNA and analyze its mRNA expression and plasma glucose levels after high glucose injection in Giant gourami. We also compared its sequence variability among carnivorous and herbivorous fish. The GCK mRNA was identified using polymerase chain reaction (PCR) method from the fish liver. Its mRNA level was analyzed by real-time PCR (qPCR). Giant gourami GCK mRNA sequence was 2104 nucleotide long, encoding 478 amino acids, and shared high similarity with other fish. GCK was mainly expressed in the liver. The mRNA level of GCK was highly up-regulated after 6 hours of high glucose injection, in-line with the plasma glucose in the blood. There are no major differences observed in the GCK amino acid sequences among Giant gourami and other fish. The knowledge gained from this study could be used as a reference for further exploration of metabolic regulation in Giant gourami.

Abstract. Irmawati, Meimulya, Tassakka ACMAR, Nadiarti, Rukminasari N, Kadriah IAK, Nasrullah H, Alimuddin. 2022. Identification, genetic diversity, and comparative evolution of the striped snakehead Channa striata (Bloch, 1793) in Wallacea, Indonesia. Biodiversitas 23: 3327-3337. Striped snakehead, Channa striata populations have declined in some areas of Wallacea. This study aimed to identify the species, analyze the genetic diversity, and trace the evolutionary relationships of snakeheads in the Wallacea region with snakeheads in other geographic areas. This study was identifying all specimens in this study as C. striata. The Wallacean C. striata sequences comprised three haplotypes with five polymorphic sites (single nucleotide polymorphisms, SNPs). No mutations were detected in the COI nucleotides of C. striata in the Tempe Lake complex, Patampanua River, and Bojo River; therefore, they belonged to the same haplotype. The C. striata from the Tangkoli tertiary drainage had unique haplotypes that differed from other C. striata haplotypes. The intraspecific genetic distance within C. striata was low while the interspecific genetic distance within the genus Channa was quite large, indicating that mutation rates are quite high in the genus Channa. Haplotype evolution showed that C. striata in Wallacea shared a common ancestral pathway with C. striata in Kalimantan, Java, and Bali and had a different ancestral pathway with C. striata in Lampung (Sumatra). The nucleotide composition of the C. striata COI gene followed the general pattern of the Teleostei and the Pisces superclass (T>C>A>G) with the G+C base percentage lower than the A+T percentage. The data from this study will be useful as a basis for designing germplasm conservation strategies and designing strategies to maintain C. striata populations and develop strains to meet future needs.

Abstract. Carman O, Mukti AT, Zairin JR M, Alimuddin. 2023. Reproductive performances of triploid male and female Nile tilapia Oreochromis niloticus (Linnaeus, 1758) at different ages. Biodiversitas 24: 4235-4242. Triploidization has been known as a chromosome set manipulation strategy to produce sterile fish. This study aimed to examine the reproductive and sterility performances of triploid male and female Nile tilapia Oreochromis niloticus (Linnaeus, 1758) at different ages. The triploidization process using heat shock of 41°C for four minutes at four Minutes After Fertilization (MAF) of the zygote old made the population of triploid tilapia. Two steps of fish rearing were conducted, namely indoor fish rearing and outdoor fish grow-out. Fish were reared in a controlled laboratory (indoor) at the Reproduction and Genetics Laboratory of Aquatic Organisms, Department of Aquaculture, Faculty of Fisheries and Marine Science, IPB University for four months, and then fish grow-out was performed in a controlled pond for two months. Reproductive performances such as Hepatosomatic Index (HSI), Gonadosomatic Index (GSI), gonadal development, and sterility of triploid and diploid for both male and female tilapias were analyzed. These results showed that triploid tilapia generally indicated late gonadal development and growth compared to diploids before and during maturation. Triploid female tilapia showed a lower HSI than diploid female tilapia (P<0.05). Otherwise, triploid and diploid males showed the same HSI. GSI of triploid males and females were lower than diploid males and females (P<0.05) at every age, namely three-, four-, five- and six-month-old fish. Based on the size and histology of the gonad, triploid male and female tilapias showed sterile characteristics with gametogenesis inhibition.

Abstract. Tarigan N, Sudrajat AO, Arfah H, Alimuddin A, Wahjuningrum D. 2023. Potential use of phytochemical from ethanolic extract of green seaweed Ulva reticulata in aquaculture. Biodiversitas 24: 6868-6879. Ulva reticulata is green seaweed with potential phytochemical properties in the aquaculture sector. Therefore, this study aims to determine phytochemical components and evaluate the toxicity of Ulva reticulata ethanolic extract on aquatic animals. The primary constituents in the sample were extracted using the maceration method with 96% ethanol. The antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, while toxicity level was determined using the Brine Shrimp Lethal Test (BSLT) method at concentrations of 0, 10, 100, 300, 500, 1000, and 2000 mg L-1. The results showed that Ulva reticulata ethanolic extract was qualitatively composed of alkaloids, flavonoids, saponins, tannins, phenols, and steroids with mid (++), low (+), low (+), low (+), low (+), and mid (++) activity levels, respectively. Based on quantitative analysis, the sample was composed of sitosterol (19.01 mg g-1), stigmasterol (35.00 mg g-1), saponins (17.04 mg g-1), flavonoids (82.16 mg QE 100 g-1), total phenols (144.00 g QE 100 g-1), and tannins (49.03 mg g-1). Furthermore, Ulva reticulata ethanolic extract had a strong antioxidant level with a 50% inhibitory concentration (IC50) of 53.00 ppm. The toxicity test showed that the 50% lethal concentration (LC50) of the sample was 481.86 mg L-1. These results showed that Ulva reticulata ethanolic extract was a non-toxic material with a high potential for phytochemical properties that could be beneficial for fish growth, reproduction, and health.
