“…Hence, Kottelat (2013) has postulated that T. douronensis found in Peninsular Malaysia and Borneo (Sabah and Sarawak) is a synonym of T. tambra [ 52 ]. Despite the unstable taxonomy, researchers in Indonesia continue to use T. douronensis for species identification instead of T. tambra [ 94 , 95 , 96 , 97 ]. This postulation has been supported by Rahayu et al (2015) as their study reported that T. tambroides and T. douronensis are distinct species through genetic classification, along with morphological classification [ 98 ].…”

The king of rivers or mahseer comprises three genera: Tor, Neolissochilus, and Naziritor, under the Cyprinidae family. The Tor genus has been classified as the true mahseer due to the presence of a median lobe among the three genera. The Tor species are widely distributed across Southeast (SE) Asia, and 13 Tor species have been reported previously: Tor ater, Tor dongnaiensis, Tor douronensis, Tor laterivittatus, Tor mosal, Tor mekongensis, Tor putitora, Tor sinensis, Tor soro, Tor tambra, Tor tambroides, Tor tor and Tor yingjiangensis. However, the exact number of valid Tor species remains debatable. Different and unstandardized approaches of applying genetic markers in taxonomic identification and morphology variation within the same species have further widened the gap and ameliorated the instability of Tor species taxonomy. Therefore, synchronized and strategized research among Tor species researchers is urgently required to improve and fill the knowledge gap. This review is a current update of SE Asia’s Tor species, outlining their distribution, morphology, and genetic identification. In addition, the present review proposes that there are ten valid Tor species in the SE Asian region. This list will serve as a template and standard to improve the taxonomy of the SE Asian Tor species, which could serve as a basis to open new directions in Tor research.

“…Penelitian mengenai ikan semah telah banyak dilakukan, di antaranya pada aspek genetika populasi (Arifin et al, 2015), pematangan gonad (Subagja et al, 2015;Mellisa et al, 2019;Rahimi et al, 2019), pemijahan buatan (Ingram et al, 2005;Subagja et al, 2013), inkubasi telur (Effendi et al, 2015), pemeliharaan larva (Ingram et al, 2005), dan pemeliharaan benih dengan perlakuan pakan (Yanto & Hasan, 2014;Radona et al, 2016). Kegiatan penelitian menunjukkan bahwa ikan induk semah yang dipelihara sudah mampu beradaptasi pada kondisi kolam budidaya dan dapat bereproduksi melalui pemijahan buatan, serta pemijahan semi-alami.…”

Ikan semah (Tor douronensis) termasuk salah satu spesies dari genus Tor yang memiliki nilai ekonomis tinggi. Untuk meningkatkan produktivitas, informasi pertumbuhan benih yang dipelihara pada sistem budidaya karamba jaring apung (KJA) perlu dilakukan karena ikan semah umumnya dibudidayakan pada kolam dengan air yang jernih. Penelitian ini bertujuan untuk mendapatkan informasi laju pertumbuhan benih ikan semah generasi pertama dengan perlakuan padat tebar yang berbeda pada sistem pemeliharaan KJA. Percobaan dilakukan di Waduk Cirata, Cianjur, Jawa Barat selama lima bulan. Ikan uji (panjang total: 7-8 cm; bobot: 5-6 g) dipelihara di KJA (padat tebar 50, 75, dan 100 ekor/m3 dengan tiga kali ulangan). Pakan apung komersial dengan kadar protein 40% diberikan sebesar 6% per biomassa yang diberikan dua kali sehari. Parameter yang diamati yaitu pertumbuhan bobot mutlak, sintasan, laju pertumbuhan spesifik (SGR), dan biomassa. Hasil percobaan menunjukkan bahwa perlakuan padat tebar 50 ekor/m3 menghasilkan pertumbuhan terbaik dengan bobot akhir 15,89 ± 1,43 g; pertambahan mutlak 10,48 ± 1,41 g; sintasan 94,67 ± 4,6%; dan SGR 0,75 ± 0,04%. Dari hasil penelitian ini, padat tebar 50 ekor/m3 merupakan kondisi yang terbaik untuk pemeliharaan benih ikan semah di KJA. Hasil penelitian ini dapat dijadikan informasi awal tentang potensi budidaya ikan semah dengan sistem budidaya KJA perlu dikembangkan di masa yang akan datang.Semah mahseer (Tor douronensis) is a species from the genus Tor and highly valued in local and national markets. Nevertheless, the fish production from net cage is currently limited. In order to increase its productivity, research on the growth of semah mahseer fingerlings reared in floating net cage systems needs to be carried out as this species is predominantly cultured in the clean water ponds. This study was conducted to obtain information on the growth performance of the first generation of semah mahseer fingerlings reared with different stocking densities in a floating net cage system. The experiment was carried out in the floating net cage located at Cirata Reservoir, Cianjur, West Java, for five months. Fingerlings (total length: 7-8 cm; body weight: 5-6 g) were reared in the floating net cage (stocking density of 50, 75, and 100 ind./m3 with three replications). The fish were fed with a commercial diet (protein content of 40%) given at 6% of biomass twice a day. The parameters observed included weight gain, survival rate, specific growth rate (SGR), and biomass. The results showed that the stocking density of 50 ind./m3 had the best performance in terms of final weight of 15.89 ± 1.43 g, weight gain of 10.48 ± 1.41 g, survival rate of 94.67 ± 4.6%, and specific growth rate of 0.75 ± 0.04%. Based to the results of this study, the stocking density of 50 ind./m3 is the best condition for rearing semah mahseer fingerlings in floating net cages. The findings of this research can be used as the basic information for future aquaculture development of semah mahseer in net cages.

“…With the presence of antidopamine, the neurotransmitter is expected not to inhibit gonadal maturation so that the gonadal maturation process can be achieved more quickly. The combination of PMSG and antidopamine hormones has a positive effect on the reproductive performance of Tor douronensis, Channa striata, Poropuntius tawarensis, and Osteochilus hasselti [11,12,13,14,15]. The combination of PMSG and antidopamine hormones is expected to provide optimal results in the gonad maturation of bileh fish.…”

Bileh fish (Rasbora maninjau) still have difficulty spawning in a controlled manner in aquaculture containers because the maturation of female fish gonads is slow and takes a long time. Internal factors, including the hormonal system, strongly influence the maturation of fish gonads. This study aims to determine the effect of Pregnant Mare Serum Gonadotropin (PMSG) and antidopamine on female gonads of bileh fish. The research used an experiment with a CRD (Completely Randomized Design) experimental design. The experiment consisted of four treatments and three repetitions. The treatments were the administration of PMSG and antidopamine hormones at different doses through feed, namely: 0 ml/kg feed (P1), 0.5 ml/kg feed (P2), 1 ml/kg feed (P3) and 2 ml/kg feed (P4). The research procedures included container and fish preparation, hormone, and feed preparation, fish rearing, and data collection. The test parameters evaluated were weight gain (Wg), gonadosomatic index (GSI), and gonadal maturity level (GML). Data on test parameters were analyzed with statistics (Anova). The research results showed that the administration of PMSG hormones and antidopamine through feed had a significant effect on weight gain, gonadosomatic index and gonad maturity level of bileh fish (P<0.05). Effective and best treatment at P3 (1 ml/kg feed) with Wg 0.22grams, GSI 8.58%, and GML IV 60%.
