Abstract
Horabagrus brachysoma,
a threatened catfish was induced bred in captivity for the stocking material. A
comparative study by feeding three live feeds (mixed zooplankton, artimia and
tubifex) to larvae was undertaken during larval rearing. The rearing
performance of larvae in normal day light vs complete dark condition was also
studied. Both the experiments were carried out in triplicate glass aquaria for
a period of 21 days. The water quality parameters were within the acceptable
range in the rearing tanks of both the experiments. All the three live feeds
were accepted well by larvae. The results showed that the growth in terms of
final weight of larvae fed on mixed zooplankton was significantly highest (p<0.05)
compared to the larvae fed on artimia or tubifex. The parameters like weight
gain, SGR and yield were lowest (p<0.05) in artimia fed larvae. The survival
rate of larvae fed on mixed zooplankton, artimia and tubifex did not vary to
each other. The growth and survival of larvae reared under natural day light
and complete darkness did not also vary (p<0.05) to each other. Therefore,
the study recommends to rear this valued larva with live zooplankton in normal
condition for the captive hatchery production. The live feed like artimia or
tubifex may be an alternative when a shortage of zooplankton is experienced.
