&description=The African catfish, Chrysichthys nigrodigitatus (Lacépède1802), is an omnivorous species cultured in both fresh and brackish waters because of its good growth rate, excellent taste, and high market demand. C. nigrodigitatus were collected from a fish landing site at Ogudu/Agboyi Lagos lagoon fishing grounds on monthly basis for six months within March to August 2013. The proximate and technological properties (body characteristics and yield indices) of wild C. nigrodigitatus were carried out. The proximate composition showed that protein in the edible tissue of the fish was 18.70% the lipid, ash and moisture contents were 4.50, 1.3 and 75.5% respectively. The mean and Standard deviation values of Total length (cm) and weight (g) were 27.69±2.05 and 159.87±28.48 respectively. However, the data obtained for the yield characteristic revealed a mean decrease in the order of fillet, head, frame and gut 43.92 > 32.38 > 17.06 > 5.74. This study shows that Chrysichthys nigrodigitatus has a high fillet yield and belong to high protein and semi high oil category of fish species.&picture=http://www.aascit.org/aascit/decorators/img/journal/892.jpg)
