Abstract:
The growth and survival rate of Clarias gariepinus larvae fed with cyprico (D1), Inert diet (egg
white + fish meal) (D2) and a combination of both diets (D3) were investigated for a period of
forty two days (6 weeks).each treatment was applied to 50 post yolk sac fry in triplicate plastic
tanks. The feed conversion ratio, mean feed intake, mean percentage weight gain, mean specific
growth rate, mean weight gain values and the survival rate were calculated. Among the three
treatments D2 had the lowest FCR value of (1.24+_0.37b
), mean feed intake of 0.21 +_ 0.18 and
lowest percentage weight gain of (220.00+_323.69a
). Diet D3 had the highest FCR value of
(2.98+_2.38a
) and PWG of (1530.00+_323.69a
) but had the lowest survival rate of 36%. Meanwhile
D1 had the highest survival rate of 60% and highest specific growth rate of (11.93+_8.95a
). It was
therefore concluded that the combination of cyprico and inert diet is the best fed for Clarias
gariepinus larvae culture. |
