Berbagai ancaman terhadap populasi belida di alam, seperti rendahnya nilai indikator ketersediaan induk di alam (15%), tingkat pemanfaatan yang tinggi, dan beberapa aturan perlindungan sebagai bukti adanya kekhawatiran kepunahan belida, menunjukkan perlunya upaya pelestarian tertentu menuju pengelolaan belida yang berkelanjutan. Kajian bertujuan untuk memformulasikan upaya menjaga keberlanjutan populasi belida di alam dan mendukung upaya peningkatan produksi, dengan melihat kondisi terkini perikanan belida baik dari aktifitas penangkapan maupun budidaya. Analisis sederhana dilakukan terhadap produksi dan hasil tangkapan belida di wilayah Propinsi Riau serta perkembangan kegiatan budidaya. Hasil menunjukan bahwa terdapat beberapa hal positif yang mendukung pemanfaatan belida sebagai komoditi budidaya. Dari sisi penangkapan, kontribusi belida terhadap total produksi perikanan perairan darat baik secara lokal (Riau) maupun nasional adalah relatif kecil, namun sampai dengan saat ini kebutuhan pasar dan industri lokal Riau hingga luar Riau masih bisa dipenuhi. Di samping itu, terdapat mekanisme pasar yang memberlakukan harga tinggi pada ukuran besar serta keberadaan lubuk larangan sebagai daerah yang dilindungi. Hal positif lainnya adalah latar belakang genetik yang memungkinkan pemanfaatan benih dan indukan dari lokasi Kampar dan Palembang untuk keperluan pemulihan di alam. Serta telah dikuasainya teknologi pemijahan belida dalam lingkungan terkontrol di luar habitat alaminya. Di sisi lain masih terdapat kondisi yang tidak mendukung keberlanjutan sumber daya ikan belida antara lain kondisi alami habitatnya yang sudah mengalami degradasi. Degradasi yang lebih nyata terlihat diduga lebih cepat berdampak jika dibandingkan dengan upaya pemulihannya. Budidaya diyakini mampu menjembatani percepatan pemulihan tersebut guna meningkatkan produksi ikan belida dalam hal ini.Various threats occurred to clown knifefish (belida) populations in wild nature, such as the low value of indicators for the availability of broodstock in nature (15%), high utilization rates, and several protection regulations as evidence of clown knifefish extinction concerns, indicate the need for certain conservation efforts towards sustainable clown knifefish management. The study aims to formulate efforts to maintain the sustainability of clown knifefish populations to population also the needs in increasing production, by looking at the current conditions of clown knifefish fisheries both from fishing and aquaculture activities. A simple analysis was carried out on the production and catch of clown knifefish in Riau Province as well as aquaculture. The results show that there are several positive things that support the use of clown knifefish as an aquaculture commodity. In terms of fishing, the contribution of clown knifefish to total inland fishery production both locally (Riau) and nationally is small relatively, however until now the market and industrial needs of local Riau to outside Riau can still be met. In addition, there is a market mechanism that imposes a high price on large sizes as well as the existence of ‘lubuk larangan’ as a protected area. Other positive is the genetic background that allows the use of seeds and broodstock from Kampar and Palembang locations for recovery purposes in nature. Also technological developments of spawning in a controlled environment outside their natural habitat. On the other hand, there is unsupported condition to the sustainability of clown knifefish resources, including the degradation of habitat. The more obvious degradation is seen having a faster impact than the recovery effort. Aquaculture is believed to be able to bridge the acceleration of the recovery in order to increase the production of clown knifefish in this case.

Penelitian pemeliharaan ikan belida, (Chitala lopis Bleeker, 1851) secara ex-situ bertujuan untuk mendapatkan teknik pembenihan yang tepat di luar habitat alaminya. Serangkaian eksperimen dilakukan adalah: 1) pemeliharaan benih dalam akuarium dengan padat tebar berbeda (45, 90, dan 180 ekor/90 L); 2) pemeliharaan benih dalam akuarium dengan jenis pakan berbeda (pakan buatan dan cacing tubifex); 3) pemeliharaan benih dalam waring dengan padat tebar berbeda (10 dan 20 ekor/m2); dan 4) pembesaran dalam waring dengan jenis pakan berbeda (cacing tubifex; cacing tubifex + pakan buatan, dan pakan buatan). Pemeliharaan benih dalam akuarium menggunakan ukuran awal 3,4 cm selama 30 hari memperlihatkan kepadatan 45 ekor/90 L memberikan laju pertumbuhan bobot terbaik sebesar 3,1%/hari dengan sintasan 96,7 ± 1,33%. Pemeliharaan lanjutan selama dua bulan dalam akuarium dengan pemberian jenis pakan berbeda menghasilkan pertumbuhan bobot tertinggi pada benih yang diberi pakan cacing tubifex sebesar 2%/hari dengan sintasan 29 ± 3,42%. Pemeliharaan benih ukuran 4,9 cm dalam waring yang diletakkan dalam kolam tanah menghasilkan pertumbuhan dan sintasan yang lebih tinggi pada padat tebar 10 ekor/m2 dengan laju pertumbuhan bobot 2,6% per hari dengan tingkat sintasan sebesar 77,3%. Pembesaran benih dalam waring dengan ukuran tebar 8-9 cm selama dua bulan menghasilkan pertumbuhan bobot yang lebih tinggi pada benih yang diberi pakan cacing tubifex (1,3%/hari) dibandingkan dengan pakan buatan (0,6%/hari) dan campuran pakan buatan + cacing tubifex (1,0%/hari).Research on the domestication of featherback fish, (Chitala lopis Bleeker, 1851) outside of their natural habitat was carried out primarily to obtain its feasible breeding techniques. A series of experiments was carried out including 1) seed rearing in aquariums with different stocking densities (45, 90, and 180/90 L); 2) rearing of seeds in aquariums with different types of feed (artificial feed and tubifex); 3) seeds rearing in net cage with different stocking densities (10 and 20 fish/m2); and 4) grow-out in net cage with different types of feed (tubifex; tubifex + artificial feed, and artificial feed). The results showed that seeds with an initial size of 3.4 cm reared in an aquarium for 30 days with a density of 45 fish/90 L produced the best weight growth of 3.1%/day with survival rate of 96.7 ± 1.33%. Two months of continued rearing carried out in an aquarium produced the highest weight growth for seeds fed with tubifex of 2%/day with survival rate of 29 ± 3.42%. Rearing of seeds sized 4.9 cm in net cage placed in earthen pond resulted in higher growth and survival than that of aquariums. The best density was 10 fish/m2 with weight growth rate of 2.6% per day and survival rate of 77.3%. Seeds sized of 8-9 cm cultured in net cage for two months produced higher weight growth when feed with tubifex (1.3%/day) than that of feed with artificial feed (0.6%/day) and mixture artificial feed + tubifex (1.0%/day).

“…The knowledge of fish reproduction is the most important in sustainable fisheries management, as well as to sustain fish processing business especially in Barito Kuala District. Numerous studies closely related to the featherback have been devoted to describe on reproductive biology [13,32,33], fecundity [6,34,35], genetic [36,37], length-weight relationship and condition factor [15,38], feeding habits [39,40], the age and growth [41], population dynamics [19], culture strategy [42,43] and conservation measures for this species [20,44]. In addition, Wibowo and Marson [37] reported that morphometric and meristic of N. chitala from Barito River, South Kalimantan were similar to those of C. lopis and N. notopterus from Kampar River, Riau Province, but genetically different from each other.…”

“…It is locally called "pipih" because of having flat body form (Figure 1). It belongs to family Notopteridae (fish with knifeback).Their unique styling also makes it kept in aquariums as ornamental fish [6].According to Arifudin [7], the featherback with medium size reach maximum of 100 cm length with average weight of 0.5-1 kg, while in nature it can reach up to 2-4 kg of fish. Its body shape is flat with small head size and at the nape of its neck looks hunchback.…”

Barito Kuala District is the largest producer of the featherback (Notopterus chitala) in South Kalimantan Province, Indonesia. It contributes about 42.29% of total regional fisheries production. Recently, supply and demand of raw material for fish chips processing business is completely dependent on the catch from the rivers. Ironically the capture fishery production for featherback tends to decline, which absolutely affecting on production volume and selling expense of the fish products. No commercial aquaculture supports this business, so far. Data on capture fishery, fish processing business and fish farming were tabulated and analyzed using descriptive method. There was a great market opportunity for featherback chips in this area of study, where the demand of fish chips (36 tons/year) was six times higher than the supply to the market (6 tons/year). The average annual profit received by the producer was USD 897. The Net Present Value (NPV), Internal Rate of Return (IRR), and Net Benefit Cost Ratio (Net B/C) were USD 2,796, 137%, and 4.59 with the Payback Period (PP) value was 8 months 15 days, indicating business was considered feasible and profitable, as well as has the favorable prospect. To increase the values, the culture business should be promoted. An attempt was made by Freshwater Fish Culture Center Mandiangin to culture them; however, the result are still being challenged to overcome this problem. The ideal interconnection of the three key issues was further discussed.
