Selection of suitable media and intervals of media inoculation for culturing Tubificid worms

Abstract

Tubificid worms are aquatic invertebrates, belonging to the class Oligochaeta and family Tubificidae, used as an important live food for fishes. The study was conducted to culture Tubificid worms under running water in order to develop a suitable culture media and an optimum duration of media inoculation for culturing Tubificid worms. The worms were cultured under two experiments in cemented culvert system (160×25×10 cm3) for 90 days. In the first experiment the worms were cultured in three different media designated as treatment-I, treatment-II and treatment-III. The highest yield (503.39±22.98 mg cm-2) was found at 70th day of culture duration in the culture media containing a mixture of 35% mustard oil cake, 20% wheat bran, 25% cow-dung and 20% fine sand (treatment-III). Only 1.99 kg media ingredients valued BDT 29.85 were needed to yield 1 kg worms. In the second experiment, the worms were cultured at three different intervals of media inoculation i.e., 6, 10 and 15 days interval designated as treatment-I, treatment-II and treatment-III respectively using the media found best in the first experiment. Inoculation of media at 10 days interval showed significantly (P<0.01) higher production (488.94±5.60 mg cm-2).DOI: http://dx.doi.org/10.3329/jbau.v10i2.14925 J. Bangladesh Agril.

Effects of Wetting Media Cattle Blood, Rice Gruel and Water on the Yield and Amino Acid Composition of Tubificid Worms

“…Ahmed and Mollah (1992) suggested 20% MOC, 35% WB, 25% cow dung (CD) and 20% sand as a suitable medium for the sustainable growth of tubificid worms. However, Mollah et al (2012) obtained higher production by using a mixture of 35% MOC, 20% WB, 25% CD and 20% sand. Mariom and Mollah (2012) suggested using a mixture of 20% MOC, 20% WB, 30% SBM, 20% CD and 10% sand as the best medium to culture tubificid worms.…”

PEMANFAATAN BUNGKIL INTI SAWIT SEBAGAI MEDIA PERTUMBUHAN CACING SUTRA (Tubifex sp.)

“…Rerata populasi cacing sutra berdasarkan Gambar 2 menunjukkan pertumbuhan cacing sutra tertinggi diperoleh pada media 50% bungki inti sawit yaitu sebanyak 111.008 ind/m 2 , sedangkan populasi terendah terdapat pada media 100% lumpur sawah sebanyak 23.989 ind/m 2 . Jumlah populasi dari fekunditas cacing sutra dapat berbeda karena dipengaruhi oleh suhu, aliran air, dan bahan organik yang ada pada media budidaya (Mollah et al, 2012). Hasil analisis statistik dari biomassa dan populasi cacing sutra menunjukkan bahwa perbedaan formulasi media bungkil inti sawit memberikan pengaruh nyata terhadap biomassa cacing sutra (p<0,05).…”

Pengaruh Ketebalan Media Budidaya Cacing Sutra (Tubifex sp.) Menggunakan Lumpur Limbah Budidaya Lele

“…Pursetyo dan Putra (2011) menghasilkan 3180,0±314,7 g/m 2 dengan media lumpur dan kotoran ayam kering dengan pemupukan setiap lima hari. Mollah et al (2012) dapat menghasilkan cacing sutera sebesar 2802,6±220,3 g/m 2 pada media pasir halus, kotoran sapi, mustard oil cakedan wheat bran. Rendahnya produksi biomassa cacing sutera ini disebabkan karena perbedaan penggunaan bahan sebagai media.…”
