Abstract

Spiny Eel, Mastacembelus armatus categorized as endangered is a highly potential species in Bangladesh. Two different experiments were conducted on domestication and induced breeding of Spiny Eel, M. armatus at mini hatchery cum breeding complex under the Department of Fisheries Biology and Genetics, Bangladesh Agricultural University. For domestication, fish were reared under three different treatments (treatment I, II and III) each having three replications (R₁, R₂, R₃) in nine indoor cisterns (2.33 m × 1.34 m area each) for six months and fed with three different feeds namely commercial supplementary feed (Mega feed), trash fish and chicken viscera. Highest growth performance was observed upon statistical analysis in treatment II fed with trash compared with treatment I and III. Subsequently four induced breeding trials were conducted using carp pituitary gland (PG) extract. Male and female broods were induced to breed using different doses (35-100 mg.kg^-1 body weight of female and 5-10 mg.kg^-1 body weight of male) of PG extract. PG dose of 35 & 40 mg.kg^-1 body weight precipitated ovulation but successful fertilization (82.00 ± 2.21) was observed at the dose of 40 mg.kg^-1 body weight. Data were analyzed using one-way analysis of variance (ANOVA).
