EMBRYONIC AND LARVAL DEVELOPMENT OF A RED STRAIN OF THE EGYPTIAN AFRICAN CATFISH (Clarias gariepinus Burchell, 1822)
Abstract: Egyptian African
catfish is one of several African catfish (Clarias gariepinus) strains
introduced to Indonesia. Several breeding activities using that strain in
Sukamandi resulted in some individuals with redish-yellow body colour (a red
strain). Biological informations related to aquacultural aspects of that red
strain were still scarce. The present study aimed to elucidate the embryonic
and larval developments of the red strain compared to those of the black
(normal coloured) one, using the progenies obtained from artificial spawning of
each red and black coloured brooders. Results of the present study revealed
that embryonic developments of the red and black strains were similar. Their
larval development were also quite similar, however, both larvae could be
distinguished based on the pigmentation. The red strain larvae were
golden-red-yellowish in colour, while the black strain larvae were greyish
covered with dense melanophores. Total length of the red strain larvae tended
to be lower than those of the black strain.
