| description | This study was aimed to determine the growth performance and gonad maturation of Amur catfish, Silurus asotus reared in
captivity. A total of 600 juvenile Amur catfish were reared in a 20-tonne aerated fibreglass tank for 3 months. The changes to
body weight (mean ± SD) of Amur catfish at day 14 was 22.59 ± 3.59 g and attained a final average body weight of 110.95
± 19.72 g. The average body weight gains (%) were 213.50% and gradually decreased to 109.95%. The specific growth rate
recorded at 14-day intervals was 5.42%/day and fluctuated to 3.32%/day, 0.39%/day, 0.51%/day, with the corresponding
measurements of 15.36 ± 1.07 cm and increments to 24.22 ± 1.34 cm. The final total length the fishes attained was an
average of 25.58 ± 1.95 cm. The total length gain recorded was 124.61% and followed by 109.95%. The survival of Amur
catfish within the three months was 29.17%. Length-weight relationship of the Amur catfish showed a strong correlation at
log W = -2.6797 + 2.3102 log L and the value of the regression coefficient (b) equalled to 2.3102. Three stages of the oocyte
(PO = primary oocyte, PVO = previtellogenic oocyte and VO = vitellogenic oocyte) determined histologically indicated that
all-female gonad samples were in the developing stage. Matured gonad and spermatozoa were also observed in males. This
study concludes that Amur catfish attained good growth performance and fast gonad maturation in captivity and can be a
suitable species for aquaculture. |
