Efforts to cultivate snakehead fish (Chanidae) still experience many problems, especially the availability of high-quality fry. To improve the quality of fry, improving the quality of broodstock is important. Genetic factors play an important role in the selection and breeding of snakehead fish parents. Therefore, it is necessary to explore sources of superior parents with good genetic characteristics. To achieve this goal requires studies from various fields such as ecology, biology, and genetics. Genetic studies can be started by examining the identity and relationships of snakehead fish from Merauke, as a first step in finding a source of germplasm that has high diversity. The aim of this research is to analyze the cytochrome oxidase subunit 1 (COI) gene fragment of snakehead fish from Merauke, Papua. DNA isolation was carried out using the Promega kit with standard protocols, amplification of the COI gene with primers F2 and R2 with the Go Taq Green amplification kit. A total of 653 base pairs of the COI gene fragment were obtained from the sequencing process, with a nucleotide composition of T (29.9%), C (28.8%), A (24.0%), G (17.3%). BLAST results on the NCBI database show that this sequence has 100% similarity to the Channa striata sequence from Papua with sequence ID OQ405388.1. This shows that the identification results of the snakehead fish from Merauke are Channa striata. Phylogenetic tree analysis also showed consistent results, namely the formation of a clade that was the same as the Channa striata fish group derived from GenBank data.

Nitrogen plays a significant role in the growth and metabolism of microalgae. The purpose of this study was to investigate the influences of different sodium nitrate concentrations on growth, biomass, and biochemical profile in Tetraselmis chuii. Four different nitrate concentrations, 0.5, 1.0, 1.5, and 2.0 g/L NaNO3 were applied in T. chuii culture under a batch system. It was found that a low nitrate concentration of 0.5 g/L NaNO3 produced the highest specific growth rate and biomass concentration of T. chuii. On the other hand, increasing nitrate concentration led to an increase in chlorophyll a+b and carotenoid in T. chuii, with the optimum nitrate concentration found at 1.5 g/L NaNO3. Under the nitrogen limitation condition, protein content was significantly decreased, but lipid and carbohydrate content were highly accumulated in the cells. This study provides a unique phenomenon that low nitrogen concentrations not only produce higher biomass but also accumulate high lipid and carbohydrate content.

Mastacembelus sp., a member of the Mastacembelidae family, is distributed across Java, Sumatera, and Kalimantan. Mastacembelus, locally named berod fish in the Brantas River lacks population’s descriptions and morphological analyses. Morphological analyses, including morphometric and meristic descriptions, are important for precise identification and classification of kinship relationships, serving as a cornerstone in the fields of biology, taxonomy, and conservation. This study aimed to conduct a comprehensive morphometric and meristic identification of the berod fish population in the Brantas River, East Java. A total of 37 samples were collected from 6 different locations: Blitar, Tulungagung, Kediri1, Kediri2, Nganjuk, and Mojokerto. The morphometric measurements were based on 25 characters, while the meristic calculations were based on 6 characters. The data analyzed with PCA and CA using SPSS and PAST programs. The results revealed that berod fish in the Brantas River had morphological characters belongs to the Mastacembelus unicolor. However, notable disparities were observed in meristic characters, particularly in the Dorsal Fin Spines (DFS). PCA analysis showed significant differences in morphometric characters but not supported by meristic characters. These results underscore the importance of integration both morphological and meristic analyses for a comprehensive understanding of the berod fish population.

Nilem fish (Osteochilus vittatus) is a species of freshwater fish from the Cyprinidae family which has ecological and economic importance in Indonesia, with its natural habitat in rivers, swamps and stagnant waters. Accurate species identification is very important in biological research and fisheries resource management, but morphological identification methods have several limitations. DNA barcoding is a revolutionary molecular technique that uses short DNA sequences to identify and differentiate species with high accuracy. The use of DNA barcoding in identifying freshwater fish in Indonesia has shown significant development, including in a comprehensive study documenting 1,172 native freshwater fish species. The research "Genetic Identification of Nilem Fish using the DNA Barcoding Approach" aims to characterize the genetics of nilem fish, compare the genetic profiles of various populations, and evaluate the effectiveness of DNA barcoding in distinguishing nilem fish from other Osteochilus species, with the hope of contributing to fish conservation and sustainable management efforts nilem in Indonesia. The DNA sequencing results obtained a sequence with a length of 619 base pairs with the composition of Nucleotides A (27.2%), G (17.6%), C (26.4%), T (28.8%). The BLAST results with the NCBI database showed a similarity of 99.84% with the O. vittatus sequence and 99.83% with O. hasseltii. Both species are synonyms with the official name O. vittatus. Phylogenetic analysis is also in line with the BLAST results which show that the sample sequence is in the same clade as the O. vittatus and O. hasseltii sequences. Identification with molecular markers of the COI gene was successfully used in determining the species of the Nilem fish (O. vittatus).

The Sentani snakehead fish (Oxyeleotris heterodon) is an endemic fish species that inhabits Lake Sentani and several other lakes in Papua Province, Indonesia. This species has important ecological and economic value, but is vulnerable to environmental change and overexploitation. Genetic identification, especially using the Cytochrome Oxidase 1 (COI) gene, is very important for conservation efforts and understanding the genetic diversity of Sentani Snakehead Fish. DNA barcoding techniques with the COI gene have become the standard method in molecular identification of species, allowing rapid and accurate identification. Unfortunately, the Sentani Snakehead Fish faces various threats such as habitat degradation, pollution, overfishing and the introduction of invasive foreign species. Therefore, genetic research is becoming increasingly important to support conservation efforts, providing in-depth understanding of the population status and adaptive potential of species. The results of DNA amplification and sequencing of COI gene fragments showed a DNA sequence with a length of 619 base pairs with the composition A (23.9%), G (18.1%), C (29.1%), T (28.9%). The results of identification by homology analysis in the NCBI and BOLD databases showed the highest similarity at 97.58% and 97.84% with the O. lineolate sequence. This is because there is no O. heterodon sequence from the COI gene fragment found in Genbank or the BOLD system. Phylogenetic tree analysis with several sequences that have close similarities shows a difference in clade between the O. heterodon sequence from this study with the O. lineolate sequence and other species.

The limitations of fish in digesting food depend on the presence of enzymes protease, amylase, and lipase that react with substrates in the digestive channel of fish. Supplementation methods can be performed to increase fish growth by adding prebiotics and probiotics to the feed. This study aims to determine the influence of the difference in the length of time fermented prebiotic feed (sweet potato extract) and probiotics (Bacillus megaterium) on the quality of feed. The results of the physical analysis of fish feed showed the color looks brown, fishy smell, texture, and general conditions of feed seemed completely normal. Chemical analysis showed that the proteins were best improved in B3 treatment, with the period of fermentation approximately 72 hours. Biological analysis suggests that the longer the fermentation time taken, the higher the abundance of bacteria obtained.Keywords: B. megaterium, chemistry and biology of fish feed, physical analysis, sweet potatoes (Ipomoea batatas L)
