Abstract:
The effect of salinity and stocking density on the growth and survival of Barbodes
gonionotus fry were studied. Experiments were carried out at the Aquaculture
Research Station Puchong, Department of Aquaculture, Faculty of Agriculture,
Universiti Putra Malaysia, Serdang, Selangor. Parameters measured once a week
were total length (cm), weight (g) and survival (%). Water quality such as dissolved
oxygen (DO), pH, ammonia, nitrite and temperature were monitored once in two
days prior to the water change. During the study period, fry were fed ad
libitum with commercial pellets (Star Feed with 42% Crude protein), two
times daily at 09:00 and 17:00 h. In the first experiment, 2 cm B. gonionotus
fry were used and place in 6 glass aquarium (58x38x38 cm). Fry were cultured
at three stocking densities, 3, 5 and 8 fry L-1. At the end of culture
period, it was found that B. gonionotus fry stocked at 3 fry L-1
showed significantly higher (p<0.05) final weight and total length. However,
stocking density of 5 fry L-1 resulted the highest percentage of
survival at the end of the experimental period. In the second experiment, B.
gonionotus fry were cultured in water with four different salinities, 0,
5, 10 and 15 ppt. Similarly, 2 cm fry were used and placed in 6 glass aquariums
(58x38x38 cm) with 40 L water. Treatment with 15 and 20 ppt were terminated
due to mass mortality between 3-7 days of exposure. As for the rest of the treatments,
it was found that B. gonionotus fry cultured at 0 ppt showed significantly
higher (p<0.05) final body weight and total length as compared to 5 and 10
ppt. However, by the end of the experimental period, the percentage of survival
was significantly the highest at 10 ppt. This study showed that B. gonionotus
fry can be stocked at 3 fry L-1 without adverse effect on its growth
and survival and survive well at 10 ppt.
