WWW.WAS.ORG • WORLD AQUACULTURE • MARCH 2015 55 At harvest, the fish average body length was 13.6 cm and the average body weight was 12.8 g with an average daily body weight gain of 56.3 mg/d. (Fig. 6). The survival rate recorded at this phase was 87 percent. Conclusion The results of the present preliminary trial clearly indicate that silver sillago could be successfully spawned naturally in captivity. However, survival during larval rearing was very poor; therefore, future efforts to improve larviculture techniques are required. The grow-out results were not impressive and the fish required a long time to reach 12.8 g and hence their commercial viability as an aquaculture species is not promising. Nevertheless, the hatchery production of this species could serve to support restocking the depleted coastal areas around the Emirate of Abu Dhabi. Notes Omer M. Yousif, Krishnakumar K.
