Mar. Hossain et al., THE EFFECTS OF DENSITY, LIGHT AND SHELTER ON THE GROWTH AND SURVIVAL OF AFRICAN CATFISH (CLARIAS-GARIEPINUS BURCHELL, 1822) FINGERLINGS, Aquaculture, 160(3-4), 1998, pp. 251-258
The effects of stocking density, light and shelter on the growth and s
urvival of Clarias gariepinus fingerings was evaluated. In this experi
ment African catfish with initial individual mean weight 0.79 +/- 0.1
g were reared at two different stocking densities-5 fish l(-1) and 10
fish l(-1) in either sheltered or unsheltered tanks with reduced and n
ormal light condition. In all conditions growth rate was significantly
affected by stocking density. The growth rate was significantly highe
r at low densities and in reduced light conditions where shelter was p
rovided. Survival rate was in excess of 79% in all treatments and was
not affected by treatment. (C) 1998 Published by Elsevier Science B.V.
