Abstract

Studies on the effects of feeding frequency on the growth and survival with
5-day old catfish [Clarias macrocephalus, Gunither) larvae of initial size ranging
from 7.9 + 0.4 mm to 8.0 + 0.4 mm in total length were conducted in glass
aquaria over a period of 28 days at an initial stocking density of 4 fish 1" . Four
feeding frequencies in the order of five feedings, three feedings, two feedings and
one feeding day " wiiitb live food {Moina and/or Tubifex worms) were studied.
Results indicated that a feeding frequency of three times day" was as good as
that of five times when the growth of larvae in term of length-gain was compared.
Larvae under the feeding frequency of five and three times day' showed significantly
(p < 0.05) higher growth and survival than those at two feedings and
one feeding day" , The survival rate did not differ significantly at the feeding
frequency of five and three times day" . A feeding frequency of three times day
with live food was, therefore, appeared to be suitable for rearing catfish larvae at
the ambient temperature which ranged between 26 and 31°C.
