“…Making Senggarat fish one of the aquaculture products with farming activities is a very important activity that needs to be done to maintain the sustainability and availability of Senggarat fish so that it is not endangered. Is this consistent with what was said in [17] that wild fish domestication could be a strategic approach to protect endangered species. The status of sengarat fish farming is that wild fish are still being caught in the country, and there is no technology or effort to cultivate them.…”

Sengarat fish, with the Latin name Belodontichthys dinema, Bleeker 1851, is a fishery commodity with high economic value and became a proud species of the community and was used as an icon of Riau Province. The current condition is that the existence of Sengarat Fish continues to decline due to overfishing, the use of fishing gear that is not environmentally friendly, and habitat destruction. Therefore, it is necessary to domesticate as an effort to develop sengarat fish into one of the aquaculture commodities. This study aims to determine the ecological value and economic status from the angle of fishing fishers and collecting traders, as well as the public’s interest in sengarat fish farming. The research was conducted in Buluh Nipis Village, Siak Hulu District, Kampar Regency, in July 2022. The method used is a description analysis obtained from literature, interviews, and surveys. The respondents used for interviews and surveys were ten people with the status of capture fishers and one gathering merchant. The Kampar river environment, which is used as a sengarat fishing ground, has a reasonably good condition but has experienced siltation due to the conversion of land into oil palm plantations along the watershed. Based on interviews, the catch of sengarat fish by fishers has declined over the past five years. This is characterized by not every day sengarat fish caught and only existing in certain months or seasons. The economic status of sengarat fish is high economic fish, characterized by a reasonably high selling price in the market, which ranges from Rp.130,000 to Rp.150,000-per kilogram. The status of sengarat fish farming is that wild fish are still being caught in the country, and there is no technology or effort to cultivate them.

“…The difference between the Characiformes and Siluriformes species was evidenced during the embryonic development and larval stage. P. mangurus being a carnivorous species with predatory and competitive behavior (Arashiro et al 2020;Shiguemoto et al 2021), demonstrated rapid development of all organic systems compared to the larvae of Characiformes species, such as the differentiation of the structures of the primitive digestive tract, increasing in length and space in the lumen of the intestine a few hours after hatching. These events during the morphological development of P. mangurus are characteristic of carnivorous species (O'connell 1981; Chakrabarti et al 1995).…”

Primordial germ cells (PGCs) are embryonic pluripotent cells that can differentiate into spermatogonia and oogonia, making them a genetic source for germplasm conservation through cryobanking and the generation of germline chimeras. Therefore, PGC studies should be conducted for each species, given possible divergences in migratory patterns of PGCs. In this work, the PGCs of 3 neotropical species (Pseudopimelodus mangurus, Astyanax altiparanae, and Prochilodus lineatus) were characterized by microinjection into zygotes of mRNA synthesized from the ddx4 3'UTR sequence of P. mangurus. Visualization of labeled PGCs was achieved by fluorescence microscopy during embryonic development. In addition, ddx4 and dnd1 expressions were evaluated during embryonic development, larvae, and adult tissues of P. mangurus, to validate their use as a PGC marker. As a result, the effective identification of PGCs was obtained. DsRed-positive PGC of P. mangurus was observed in the hatching stage, GFP-positive PGC of A. altiparanae in the gastrula stage, and GFP-positive PGCs from P. lineatus were identified at the segmentation stage, with representative labeling percentages of 29% and 16% in A. altiparanae and P. lineatus respectively. The expression of ddx4 and dnd1 of P. mangurus confirmed the specificity of these genes in germ cells. These results point to the functionality of the P. mangurus ddx4 3'UTR sequence as a PGC marker, demonstrating that PGC labeling was more efficient in A. altiparanae and P. lineatus. The procedures used to identify PGCs in P. mangurus consolidate the first step for generating germinal chimeras as a conservation action of P. mangurus.

“…Wild fish adapted to aquaculture environment tend to experience a reproductive system disturbance, especially for female fish (Zohar & Mylonas, 2001). It could be caused by different and limitation of the rearing environments (Fobert et al, 2019), nutrient availability (Shiguemoto et al, 2021), egg substrates (Fukuda & Sunobe, 2017), pheromones, and environmental signals (Sorensen & Stacey, 2004) compared to its natural habitat. Aside from environmental manipulation, hormonal induction is reported to be the most successful method to stimulate the fish gonadal development for the domesticated fish.…”

Indonesian leaffish, Pristolepis grootii (Bleeker, 1852), is an undomesticated freshwater fish species native to the rivers, flooded swamps, and tributaries of Indonesia. The fish is mainly captured for consumption. In order to prevent its extinction and supply its growing demands, the artificial breeding of the fish should be developed. The purpose of this study was to determine the optimum dose of luteinizing hormone-releasing hormone analog (LHRHa) for stimulating the female P. grootii gonadal development at a dosage of 0, 1, 10, and 50 µg kg-1 of fish. Female fish (20.0 ± 0.6 g) were adapted for 30 days in the rearing environment and then separated into 12 aquariums with six fish per aquarium. Fish were then reared for another 21 days and fed with Tubifex sp. The LHRHa injection was conducted twice on day-7 and 14. Fish bodyweight, gonadosomatic index, gonad histology, blood estradiol-17â, and FSH-â and LH-â gene expression were evaluated at day 0, 7, 14, and 21. The results showed that the injection of the LHRHa hormone stimulated the development of fish gonads and was better achieved with a higher concentration of LHRHa. The best treatment was observed by the administration of 50 µg kg-1 of LHRHa that produced the fastest development among all treatments. This study demonstrated that the LHRHa induction could potentially stimulate the gonadal development of the newly domesticated fish. To our knowledge, this is the first study that reported the success of the induction of female gonad development in the Indonesian leaffish P. grooti.KEYWORDS:
