Tóm tắt
The study aimed to find the effect of feeding times of industrial feed on growth and survival rate of larvae and postlarvae of Giant fresh water prawn. The study included 5 treatments: (i) 5 times/day; (ii) 6 times/day; (iii) 7 times/day; (iv) 8 times/day and (v) control. Experimental tank volume was 120 liter and stocking density was 60 larvae/liter with water at salinity of 12‰. The results of the experiment showed that the length of postlarvae 15 (11.07 ± 0.15 mm), survival rate (54.4 ± 7.7%) and productivity (32,653 ± 4,646 con/m3 ) at treatments in larger 6 times/day but the difference was not statistically significant (p > 0.05) compared with the remaining treatments. It can be concluded that nursing freshwater prawn for feeding 6 times/day is most suitable.
