, fishmeal (F2) and palm kernel cake (F3) respectively. The proximate composition of P.obscurus at commencement of the study was as follows: crude protein= 19.0 ± 0.06 %, carbohydrate = 2.0 ± 0.23, fat = 4.02 ± 0.02%, ash = 5.0 ± 0.00%, moisture = 70.0 ± 8.0%, NFE = 3.50 ± 0.1% with the caloric value of 249 Kj/kg. This result at the end of the study showed that the crude protein content of the fish was 18.00 ± 0.17 %, carbohydrate= 2.00± 0.0 %, moisture was 72.2 ± 2.00%, fat = 3.00%, while ash and caloric value of the fish were 5.00 ± 0.00 % and 253 Kj/kg respectively. There were no significant differences in the food value of the other food components in these fishes. The growth rates of 0.008gm.d-1; 0.005 gm.d-1 and 0.004 gm.d-1 were calculated for specimens that fed on F1, F2 and F3 respectively, implying that F1 was the best out the three compounded feeds. Survival rates were high giving 75%, 87% and 62% respectively were significantly different from each other (P<0.05). These results are discussed considering the response of P.obscurus to formulated feeds in artificial culture systems.&picture=http://www.aascit.org/aascit/decorators/img/journal/923.jpg)

Studies were carried out to identify suitable protein sources and the level of their concentrations in formulated feeds for Par-ophiocephalus obscurus fingerlings reared in artificial culture systems for 120 days. Determinations were made with standard procedures recommended by AOAC for assessing the proximate composition of the animals at the beginning and end of the investigation. The feeds compounded for the animals contained each 28%, 28% and 28% protein derived from blood meal (F1), fishmeal (F2) and palm kernel cake (F3) respectively. The proximate composition of P.obscurus at commencement of the study was as follows: crude protein= 19.0 ± 0.06 %, carbohydrate = 2.0 ± 0.23, fat = 4.02 ± 0.02%, ash = 5.0 ± 0.00%, moisture = 70.0 ± 8.0%, NFE = 3.50 ± 0.1% with the caloric value of 249 Kj/kg. This result at the end of the study showed that the crude protein content of the fish was 18.00 ± 0.17 %, carbohydrate= 2.00± 0.0 %, moisture was 72.2 ± 2.00%, fat = 3.00%, while ash and caloric value of the fish were 5.00 ± 0.00 % and 253 Kj/kg respectively. There were no significant differences in the food value of the other food components in these fishes.

Survival rates were high giving 75%, 87% and 62% respectively were significantly different from each other (P<0.05). These results are discussed considering the response of P.obscurus to formulated feeds in artificial culture systems.
