Mystacoleucus marginatus is a type of freshwater fish that is spread in various countries with tropical climates, one of which is Indonesia. This fish can be found in the Brantas River Basin (DAS), East Java. In its development, identification of fish species needs to be done in detail and more deeply, so that the correct identification results can be obtained. This study aims to identify genetic and phylogenetic characteristics of Mystacoleucus marginatus in the Brantas River Basin based on the Cytochrome Oxidase C Subunit I (COI) gene. Test samples were taken from 11 individuals of Mystacoleucus marginatus in the Brantas watershed, from June to August 2018. The results showed that Mystacoleucus marginatus in the Brantas watershed had 2 Haplotypes with Haplotype (Hd)=0.96 diversity values and nucleotides diversity (Pi)=0.00357. These results indicate that the population in the Brantas watershed is interconnected between one location and another sampling location, this is supported by a phylogenetic topology of DNA barcodes showing a monophyletic clade, as well as a haplotype distribution indicating that the sample area is genetics are not isolated from one another. So that the type of Mystacoleucus marginatus scattered along the Brantas watershed is still in one species, which is indicated by the low level of genetic variation. Genetic identification efforts must be carried out continuously so that appropriate information can be obtained for the diversity of fish species, especially endemic fish.

The east coast of Bangka Island is an area prone to conflicts of interest, due to the use of the coast for tin mining and fishing by traditional fishermen. The threat of destruction of mangrove forests due to community tin mining on the east coast of Bangka Island has caused a decline in the crab population as the main catch of local fishermen.The study aimed to analyze efforts to manage mangrove ecosystems in conflict zones. The study was conducted from June to October 2023. The primary data was obtained through interviews fishermen community, direct observation, and documentation. The data analysis methods employed utilize a descriptive approach. Based on the survey results, the impact of tin mining activities causes a decrease in the area of mangrove forests. Reporting that the income of traditional fishermen in the productive fishing season is around IDR 65,000/day or IDR 980,000/month. Meanwhile, in the bad season, the income of traditional fishermen is IDR 13,000/day or IDR 205,000/month. Efforts to manage mangrove resources in conflict zones include mangrove restoration and mangrove forest educational tourism. The government's enforcement of regulations regarding the prohibition of tin mining in mangrove forest areas must be more massive so that mangrove resources remain sustainable. The government must significantly enhance the enforcement of legislation pertaining to the prohibition of tin mining in mangrove forest regions in order to ensure the long-term sustainability of mangrove resources.

Parosphromenus deissneri is a freshwater species known exclusively from Bangka Island, Indonesia. According to the IUCN Red List of Threatened Species in 2020, this species is endangered, and the population continues to decrease due to the consequences of open-pit tin mining on Bangka Island harming its natural ecosystem. Despite the fact that this species is regarded as endangered, no known conservation and domestication initiatives have been made to enhance its number in the wild. In this study, we propose to do domestication of P. deissneri using biotope principles and techniques to increase the P. deissneri capacity for adaptation and reproduction since these species believe they are in their natural habitat. This study was carried out from April to September of 2023 at Bangka Belitung Endemic Fish Laboratory. We designed the biotope concept using an aquarium with dimensions 200 cm x 100 cm x 50cm. Biotopes are equipped with aquatic plants, roots, twigs, dead leaves, sand, rocks, gravel, and water containing natural plankton as biotic and abiotic elements. In this study, a Parosphromenus deissneri broodstock of 20 individuals (10 males and 10 females) was maintained for a 5-month period, resulting in an 80% survival rate. During the study, one mating pair successfully produced approximately 14 eggs, 8 of which hatched. Following a 2-month larval development phase, 4 fry survived to adulthood, yielding a survival rate of 25% relative to the total number of hatched eggs. These results underscore the necessity for refined husbandry practices and optimal environmental conditions to improve fry survival and enhance reproductive success in future breeding efforts.
